STRG Active Portfolio Analysis

Created: 2026-04-06 (session 41) | All 13 TX areas surveyed (session 80) | Cross-cutting synthesis added session 82**

Summary

STRG has 195 active projects (17.7% of 1,102 total) spanning 13 TX areas. The active portfolio skews heavily toward computational modeling and simulation — not hardware. TX12 (Materials/Manufacturing) is #1, driven by three distinct clusters: additive manufacturing certification, lunar dust mitigation, and in-space manufacturing. TX09 (EDL) is an unexpected #3, explained almost entirely by computational CFD grants. TX17 (GN&C) has 9 active STRG projects — the STRG slice of a 400-project global TX17 portfolio dominated historically by SBIR (55%); see tx17-gnc.md. TX11 (Software/Computing) is dead last at 3 projects (1.5%) — striking given the breadth of software research.

Portfolio survey complete (session 80): All 13 TX areas analyzed. The full active portfolio has been characterized, with individual sections for TX01, TX05, TX06, TX07, TX08, TX09, TX11, TX12, TX17, and the May 2025 183xxx cohort (TX01 + TX03 tracks). See Cross-Cutting Observations below for portfolio-level synthesis.

The May 2025 STRG Solicitation — 183xxx Cohort (session 58)

A discrete solicitation starting 2025-05-01 produced 8 projects (all with IDs in the 183xxx range, last-updated 2026-01-23, same Program Director Matthew Deans and Program Manager Hung Nguyen). These cluster into two complementary themes:

Track 1 — Advanced Propulsion (4 × TX01.4.x):

Project Lead Org TX Concept
183683 U. Minnesota (Ilic, Gregg ARC PM) TX01.4.6 Metasurface/photonic lightsails for directed energy propulsion
183676 CSM (Beik, Barth GRC PM) TX01.4.5 MW-scale dual-rotor NEP PMAD generator
183686 UT Austin (Underwood, Adams MSFC PM) TX01.4.6 Z-pinch fusion EM propulsion (low α)
183697 Purdue (Oguri JPL) TX01.4.6 Origami diffractive sail for directed energy

Two nuclear physics survivors ([183676] NEP PMAD + [183686] Z-pinch) and two directed energy / lightsail concepts ([183683] metasurface + [183697] origami diffractive). For nuclear context see propulsion-theme.md. For diffractive sails see diffractive-solar-sailing.md.

Track 2 — PSR Power Solutions (4 × TX03.x):

Project Lead Org TX Concept
183685 U. Chicago TX03.3.2 Oxychalcogenide superconducting power transmission for PSR
183711 CSM TX03.2.2 SOFC (O₂/CH₄) for PSR mobile assets
183700 UC Berkeley TX03.3.3 Piezoelectric power conversion (radiation-hard, cryogenic)
183693 Stanford TX03.1.1 Deployable lightweight solar reflectors to redirect sunlight into PSRs

All address the core Artemis challenge: permanently shadowed regions (PSRs) receive no direct sunlight. The 4 projects span the full PSR power stack: solar collection ([183693]), superconducting transmission ([183685]), cryogenic power electronics ([183700]), and fuel storage/delivery for SOFCs ([183711]). Together they constitute an academic research layer beneath the GCD LunaGrid engineering programs — see psr-power-strg.md for full analysis.

CSM correction (session 59): CSM appears in both tracks, but via different research groups. [183676] NEP PMAD = Omid Beik (GRC PM Barth). [183711] SOFC fuel storage = Michael Mcguirk (PM Chauby) — a different CSM group. CSM's dual presence reflects institutional breadth in energy/materials, not a single PI with two grants.

[183711] is NOT a conventional SOFC project: The innovation is stimulus-responsive adsorbent materials that replace cryogenic O₂/CH₄ dewars for fuel cell propellant storage. The adsorption approach removes the heavy cryogenic infrastructure bottleneck for mobile PSR fuel cell assets.

ML mismatch pattern (session 59): [183685] and [183711] are ML-mislabeled as TX07 (resource exploration/processing) due to PSR framing in their descriptions. Human classifiers are correct; ML is confused by the application context. Both have txMismatch=Yes — see field-completeness.md Issues 16–17.

Interpretation: This is a single coordinated solicitation — not two separate programs. Deans/Nguyen structured it to simultaneously advance both advanced propulsion (long-horizon deep-space access) and PSR surface power (near-term Artemis readiness). The two-track design preserves terminated TDM nuclear programs through academic channels while directly addressing Artemis operational gaps. All TX correct per human classifier — above-average taxonomy discipline for this program pair.

TX Distribution (Active, 195 Projects)

Query: portfolio_aggregate(group_by="primaryTx", filter={"program":"STRG","status":"Active"}), snapshot 2026-04-04

TX Area Count % Character
TX12 Materials/Manufacturing 30 15.4% AM, lunar dust, ISM
TX01 Propulsion 29 14.9% Exotic propulsion + RDRE CFD
TX09 EDL 24 12.3% Computational CFD (not hardware)
TX08 Sensors/Instruments 23 11.8% Mixed hardware + simulation
TX04 Robotics 18 9.2% Locomotion, manipulation
TX06 Life Support 16 8.2% Human health research (biomanufacturing, wearable diagnostics, water chemistry)
TX03 Power 13 6.7% Solar, nuclear, conversion
TX07 ISRU 10 5.1% Regolith processing, MOXIE follow-on
TX17 GN&C 9 4.6% Navigation algorithms (cislunar focus)
TX14 Thermal 8 4.1% Novel cooling (elastocaloric, ionic liquids)
TX05 Comms/Nav 6 3.1% Optical comms, networking
TX10 Autonomous Systems 6 3.1% Fault resilience
TX11 Software/Computing 3 1.5% Minimal presence

Key surprise vs. expectation: TX08 was expected to be #1 (it dominates IRAD and SBIR active portfolios). TX12 is #1 in STRG — NASA is betting academic research most heavily on materials, manufacturing certification, and lunar surface readiness.

TX01: Propulsion — Electric Propulsion Dominance + RDRE Cluster (29 projects)

Query: find_projects(program="STRG", technology_area="TX01", status="Active"), 29 results, snapshot 2026-04-04

Sub-area breakdown

Sub-area Projects Character
TX01.2.2 Electrostatic Propulsion ~14 Hall thrusters + electrospray (ionic liquid)
TX01.3.4 RDRE ~5 Rotating detonation physics + thermal management
TX01.4.3 Nuclear Thermal Propulsion 2–3 Post-TDM materials + modeling (survives termination)
TX01.4.6 Advanced/Exotic 3 2025 183xxx cohort (lightsail, Z-pinch, diffractive sail)
TX01.1.x Storable/Cryogenic Propellants 3 Hypergolic chemistry + LH2 critical heat flux
TX01.2.1 Integrated EP Systems 1 JANUS consortium (Georgia Tech, high-power EP)
TX01.4.5 Nuclear Electric Propulsion 1 NEP PMAD generator (CSM, 183xxx cohort)

3 misclassified projects inflate or distort counts — see Issues 25–27 in field-completeness.md.

JANUS [118384] — 5-year high-power EP consortium (2021–2026, ends Sep 2026)

The flagship STRG investment in electric propulsion. Georgia Tech-led, with partners spanning CA, CO, GA, IL, MA, MI, OH, PA — 8 states, major consortium.

  • PI: Mitchell L. Walker (GA Tech) | PM: John T. Yim (NASA HQ)
  • Goal: Physics-based limits, mitigation techniques, and probabilistic lifetime assessment for ~100 kW class high-power EP systems
  • Output: Hall thruster state estimation paper (J. Physics D), ion thruster plume neutralization paper (Plasma Sources Sci+Tech), project website (januselectricpropulsion.com)
  • TRL 2→4 — highest TRL target in TX01 STRG; achievable for EP system-level physics (no hardware qualification needed)
  • Significance: 100 kW class EP is the enabling technology for nuclear electric propulsion (NEP) to Mars. JANUS builds the physics understanding that mission EP systems require. Ends September 2026 — final-year now.
  • Data quality note: GA Tech listed as MSI/PBI (Predominantly Black Institution) — almost certainly a data error. GA Tech is not a PBI. Issue not yet filed in field-completeness.md (add if confirmed).

University of Michigan Hall thruster dynasty — 5 projects

U Michigan is the dominant academic institution in Hall thruster research, with 5 active STRG grants:

ID Project Focus
158636 Hall thruster without pole erosion TRL 2→3, 2024-2028; new magnetic shielding geometry
158679 Electrodeless applied-field MPD thruster TRL 2→3, 2024-2028; high-power >10kW, crewed Mars
156333 Ultra-high thrust density Hall (>100 N/m²) TRL 2→3, 2023-2027; >100 kW, >2000s Isp target
118463 Facility effects on high-power Hall testing TRL 2→3, 2022-2026; ground test validity for >100 kW
156327 PIC anomalous transport closure models TRL 2→3, 2023-2027; multifidelity simulation

Michigan covers the full Hall thruster stack: new shielding geometries, ultra-high thrust density, facility-effect corrections, and plasma physics modeling. Consistent PI team likely coordinated through the JANUS consortium.

RDRE academic cluster — 5 projects (feeds GCD RDRE TDM [158559])

ID Project Lead Org Focus
118450 Wave/mode structure in RDREs UIUC 5,870 views (highest in TX01); wave multiplicity physics; PM Hugh Perkins (GRC)
158616 Spray-detonation dynamics Stanford Detonation initiation + propagation in liquid spray, 2024-2026
118443 Thermal management with generative design UTSA Heat loads in RDRE + laser diagnostics; 2022-2026
156358 Experimental geometry optimization Purdue Variable-geometry modular RDRE; 2023-2027; MISLABELED TX01.4.3 NTP (see Issue 27)
118450 (see above)

STRG→GCD pipeline: These 4-5 STRG academic projects provide the physics foundations for GCD RDRE TDM [158559] (MSFC+AFRL engineering program, $Xm, zero TechPort documents). PM Hugh Perkins (GRC) on [118450] = same propulsion center managing the GCD engineering program. UIUC [118450] with 5,870 views is the most-read TX01 STRG project — indicating strong interest from the RDRE engineering community.

NTP research survives TDM termination

The TDM NTP/NEP program was terminated December 2025 (see nuclear-propulsion-dual-termination.md). But STRG academic grants run to completion:

ID Lead Focus Period
158683 MIT Liquid core NTP transient modeling 2024-2028
158586 UCSB Refractory metal AM powders for SNP 2024-2028

Both started Aug 2024, both end Aug 2028 — started and will complete AFTER TDM termination. The materials science knowledge base continues. Note: WPI [158508] (refractory powder production) in the TX12 section also explicitly targets NTP/NEP — three STRG academic grants survive the program-level termination.

Stanford spacecraft charging [156329] — 3,371 views (highest EP project)

"Modeling Spacecraft Charging Incident from the Effect of Background Plasma on Satellites with Electric Propulsion" — PI Sigrid Elschot, Stanford, 2023-2027, TRL 2→3. Computational model of background plasma interaction with EP-satellite surfaces. High views reflect industry concern: as EP-equipped constellations (Starlink, OneWeb, etc.) proliferate, plasma-induced surface charging becomes a practical reliability issue. This is the academic research foundation for a growing commercial problem.

Misclassifications in TX01 STRG

Three projects in the TX01.2.2/TX01.4.3 bins are misclassified: - 158665 "Project Tethys: Extracting Water from Martian Environment" (WPI) — filed under TX01.2.2 (Electrostatic Propulsion). Actually an ISRU project (Mars water extraction). txMismatch=Yes; ML correctly predicts TX07.1.3. → Issue 25 - 118459 "Beamed Microwave Energy Propulsion" (PSU) — filed under TX01.4.3 (NTP). Neither nuclear nor ISRU (ML: TX07.1.3, also wrong). Beamed energy propulsion = TX01.4.6 or TX01.4.2. txMismatch=Yes. → Issue 26 - 156358 "Optimization of Device Geometry for RDREs" (Purdue) — filed under TX01.4.3 (NTP). Clearly an RDRE project (TX01.3.4). No txMismatch flag shown despite clear error. → Issue 27

TX12: Materials & Manufacturing — 3 Clusters (30 projects)

The #1 STRG TX area. Sub-area breakdown reveals three distinct investment themes.

Cluster A: Additive Manufacturing Certification (~10 projects)

NASA is funding the academic foundations for certifying AM metal parts for flight. This is the bottleneck: AM can produce complex geometries, but flight qualification is not established.

ID Project Lead Org Focus
156318 IMQCAM (flagship, 5,348 views) Carnegie Mellon AM certification institute (TX12.4.1)
118448 AM fatigue prediction from porosity/roughness Carnegie Mellon Process→property linkage (TX12.2.2)
156357 In-situ acoustic emission monitoring (AM) Georgia Tech Defect detection during LENS printing (TX12.4.2)
158508 Refractory metal powder production Worcester Polytechnic Pre-alloyed powders for NTP/NEC (TX12.4.1)
118497 Robotic in-situ consolidation (thermoplastics) UT Austin Out-of-autoclave TPC manufacturing (TX12.4.2)
156363 Computational materials (refractory HEA) Cornell High entropy alloy discovery (TX12.1.2)
158628 Refractory bond coat / oxidation protection UC Irvine CrTaO4 coatings for rocket environments (TX12.4.1)
158508 Oscillatory magnetic field AM finishing U Florida Internal surface finishing for rocket nozzles (TX12.4.1)

Notable: WPI refractory powder project [158508] explicitly mentions "nuclear thermal and electric propulsion" as target applications — continuing NTP materials research even after the TDM programs were terminated Dec 2025.

Notable: CMU has two separate STRG projects (IMQCAM institute + AM fatigue prediction), both in TX12 — the university with the deepest AM certification investment.

Cluster B: Lunar Dust Mitigation (5-6 projects)

A dedicated investment cluster responding to the Apollo lessons. Lunar dust is abrasive, electrostatic, and highly adhesive — a known threat to equipment longevity in sustained surface ops.

ID Project Lead Org Approach
156318 Doped-YSZ ceramic coatings Embry-Riddle Impact/wear-resistant coating (TX12.1.5)
182221 Bioinspired surface textures U Arkansas Anisotropic textures repelling dust (TX12.1.4)
182204 Hierarchical nanostructures (adhesion engineering) UT Austin Controlling adhesion to repel dust (TX12.1.4)
182220 Anisotropic structured surfaces UCF Electrostatic dissipative coating (TX12.1.4)
182203 Crumpled nano-ball coatings UC Irvine Deformable nanostructure coatings (TX12.1.4)

Pattern: 4 of 5 lunar dust projects have IDs in the 182xxx range (2025 cohort) — NASA issued a specific solicitation for dust mitigation in ~2024-2025. All are TRL 2→3-4, ending 2028. The diversity of approaches (ceramics, bioinspired, nanostructures, electrostatics) suggests no consensus yet on the optimal solution.

Cluster C: In-Space Manufacturing (ISM) (5 projects)

Building the academic foundations for manufacturing structures in space — relevant to Artemis surface habitats and large space telescopes.

ID Project Lead Org Focus
156340 Modeling robotic deformation processing MIT Large structures via robotic incremental forming (TX12.4.1)
156334 Autonomous EHD inkjet printing for ISM U Wisconsin-Madison AI-controlled semiconductor printing (TX12.4.2)
182205 Weld-ASSIST (welding digital twin) U Illinois Chicago Digital twin for in-space welding (TX12.4.2)
182219 Lunar metal welding defect modeling UT Dallas Keyhole instability in lunar vacuum welding (TX12.4.2)
158429 Regolith AM feasibility Rice University ISRU-based additive manufacturing (TX12.4.1)

Note: The EHD inkjet project [156334] (U Wisconsin) is related to SEADS [158773] in FO program (Intel/Fujifilm partnership). SEADS is the flight demo of EHD semiconductor printing that the Wisconsin work supports at the foundational level.

Other TX12 Notable Projects

  • 118371 Grain Boundary Engineering of Thermoelectrics for RTGs — Northwestern, TX12.1.7. Using grain boundary engineering to improve thermoelectric efficiency for RTGs. Classified TX12 (Special Materials) not TX03 (Power) — cross-boundary. Active 2022-2026.
  • 158653 Elastocaloric Refrigeration (Iowa State) — TX12.1.7, TRL 2→3, 2024-2027. This is a third elastocaloric project in TechPort (alongside Texas A&M [158568] + UIUC [158417] in TX14.X). Iowa State is classified as special materials (TX12); the other two as thermal management (TX14.X: Other). Same technology, human classifier split across two TX areas within the same solicitation. See tx14-thermal-management.md and field-completeness Issue 18.
  • 118268 Hierarchically Tailorable Composites (UW-Madison) — TX12.1.1, TRL 2→3. Composite materials for large space telescopes and dimensionally stable structures. HWO-relevant.

TX09: EDL — Computational CFD, Not Hardware (24 projects)

TX09 is #3 in STRG active projects. The surprise: it's not parachutes or heat shields being built — it's computational simulation tools and models. Of 24 projects, ~13 are in TX09.4.5 (Integrated Modeling and Simulation for EDL).

Query: find_projects(program="STRG", technology_area="TX09", status="Active"), 24 results, snapshot 2026-04-04

Sub-area breakdown

Sub-area Projects Focus
TX09.4.5 Integrated Modeling and Simulation ~13 CFD, turbulence modeling, hypersonic aero
TX09.3.1 Touchdown Systems 3 Autonomous landing algorithms
TX09.4.6 Instrumentation for EDL 2 Laser diagnostics, TPS sensors
TX09.2.1 Aerodynamic Decelerators 2 Parachute FSI (Stanford, UIUC)
TX09.1.1 Thermal Protection Systems 2 MHD entry plasma, intumescent ablators
TX09.3.2 Propulsion for Landing 1 Green propellant plume chemistry (UCF)

Key clusters

Hypersonic turbulence/CFD cluster (~6 projects): UC Boulder dominates (3 projects: ACCESS consortium [118383], wall-modeled LES [156378], MHD entry plasma [158557]). Also USC hypersonic boundary layer [156375], MIT large-eddy simulation [156323], Colorado State / UT Austin thruster jet interaction [158405]. These are all computational tools for predicting aerothermal environments during entry.

ACCESS multi-university consortium [118383]: 5 universities (Colorado, UIUC, Kentucky, Minnesota, New Mexico) + 3 international (Oxford, NCAR-Bari, Italian Institute). Active 2021-2026. TRL 2→4. The flagship STRG investment in EDL simulation.

Plume-surface interaction (PSI) cluster (~4 projects): Johns Hopkins plume-surface thermal [118454], UC Berkeley thruster chemistry [156331], UIUC PSI dynamics [158654], Auburn crater formation [158007]. All studying how retropropulsion engines affect lunar/Mars regolith. Directly relevant to crewed lunar and Mars landers.

Taxonomy mismatch in TX09: Two projects are misclassified: - [158641] Stanford "Adaptive World Models for Space Robotics" — classified TX09.4.5 (EDL simulation) but is actually about ML-based robot world models for RPOD/surface robotics. Should be TX04 or TX10. - [156373] Georgia Tech "Image-Based Relative Navigation" — classified TX09.4.5 but is about visual RPOD navigation. Should be TX17.2.1.

TX07: ISRU — 5 Technology Tracks, 1 Mislabeled Propulsion Project (10 projects)

Query: find_projects(program="STRG", technology_area="TX07", status="Active"), 10 results, snapshot 2026-04-04

The 10 STRG active TX07 projects span a wide range of approaches to in-situ resource utilization. All are TRL 2→3. All share Deans/Nguyen as Program Director/Manager. The cluster runs across 5 genuine technology tracks plus one misclassified project.

ID Project Lead Org Track Period Notes
158209 Apollo Regolith Landing Pad Bricks UTSA (HSI) Thermochemical 2024-2026 1,730 views; uses Apollo samples + simulants; PM Edmunson (MSFC); ends Jul 2026
118468 Hollow Anode MRE for Lunar O2 Caltech Electrochemical 2022-2026 Faber lab; MRE at 1600°C; novel anode design; ends Jul 2026
158632 H2 Plasma-Enhanced ISRU O2 UIUC Plasma 2024-2028 Sankaran; PM Engeling (JPL)

158634 Cyanobacteria for Mars Bioproduction Georgia Tech Biological 2024-2028 Peralta-Yahya; PM Roberson (KSC)
156348 Biological Regolith Augmentation (Mars Agriculture) Texas A&M (MSI) Biological 2023-2027 Howe; aeroponic + microbial soil enrichment
156319 Planetary Excavation Optimization UCF (HSI) Acquisition 2023-2027 Britt; low-gravity excavation methods
158600 Debris Salvage to Lunar Feedstock Georgia Tech Non-regolith 2024-2028 Lightsey; orbital debris → commodity metal; PM Reidy; unique concept
158554 PREHEAT (propulsion mislabeled TX07) Cornell ⚠️ Propulsion 2024-2028 Petro; NEP/SEP thrusters; txMismatch=Yes; ML TX01.2.2 correct; PM Johnson (JPL)

Notable patterns:

Biological track: Two projects ([158634] Georgia Tech + [156348] Texas A&M) form the only explicitly biological ISRU cluster in TechPort. Both target Mars, both use engineered microorganisms, both are at TRL 2. PM Luke Roberson (KSC) on the cyanobacteria project — NASA's biomanufacturing expert signals institutional seriousness. If either reaches TRL 3, it would be NASA's first biological ISRU proof-of-concept.

Plasma track: Two plasma-based projects ([158632] H2 plasma + [118471] plasma-photocatalytic) share the non-thermal plasma approach for ISRU chemistry. Both target Mars atmospheric CO2 as feedstock. Different mechanisms — H2 plasma reduction vs. plasma-catalytic conversion — but same principle: use non-equilibrium plasma chemistry to drive ISRU reactions at lower energy than thermal approaches.

Debris-to-feedstock [158600]: Unique concept — does not use regolith. Instead, salvaged orbital debris is processed on the lunar surface into commodity metal feedstock (aluminum, steel, titanium) meeting purity standards for in-space manufacturing. Glenn Lightsey (Georgia Tech space systems) leads. Bridges orbital debris remediation and ISRU in a way no other project does. Low views (401) despite the innovative concept.

Issue 19 — PREHEAT misclassification: Cornell [158554] is a propulsion project (NEP/SEP electric thrusters). The "ISRU" connection is use of ISRU-derived propellant, but the technology being developed is the thruster. Human classifier focused on propellant source rather than technology class. ML correct. See field-completeness.md Issue 19.

Three closing in 2026: [158209] UTSA (July), [118468] Caltech (July), [118471] UAB (August) — three STRG TX07 projects end this year with no known follow-on. If results remain at TRL 3 with no Transitioned_To, they join the typical STRG academic output profile (knowledge + publications, no NASA mission application).

TX08: Sensors/Instruments — Astrophysics Detector Cluster (23 projects)

Query: find_projects(program="STRG", technology_area="TX08", status="Active"), 23 results, snapshot 2026-04-04 (session 79)

Expectation vs. reality: TX08 in SBIR and IRAD is dominated by Earth observation and remote sensing. In STRG, it is almost entirely astrophysics instrumentation — space telescope detectors, spectrometers, and enabling components for the next generation of space observatories. Only 2 projects have "Earth" as primary destination.

Sub-area breakdown

Sub-area Count Character
TX08.1.1 Detectors and Focal Planes 14 (61%) KIDs, TES, SNSPDs, CMOS — astrophysics focal planes
TX08.1.3 Optical Components 2 UV gratings, fiber nulling for exoplanets
TX08.1.5 Lasers 2 PBL lidar (Earth), lunar power beam
TX08.3.4 Environment Sensors 2 Planetary aerosol + neuromorphic gas sensor
TX08.1.4 Microwave/mm/Submm 1 mm-wave acoustic filters (comms)
TX08.1.2 Electronics 1 Spintronics extreme-environment devices
TX08.1.6 Cryogenic/Thermal 1 Holey-Si thermopiles for ice giants
TX08.3.1 Field/Particle Detectors 1 Analog CMOS for radiation environments
TX08.X Other 1 Quantum sensing Earth climate institute

TX mismatch rate: 5/23 (22%) — higher than SBIR (~4%), lower than NIAC (~50%). Most common error: classifying quantum or bio-sensing instruments as life support (TX06.3) or quantum comms (TX05.5.2).

Cluster A: Superconducting Detector Arrays (~9 projects)

The heart of the TX08 STRG portfolio is a coordinated investment in superconducting detector technologies feeding NASA's next-generation astrophysics observatories (HWO, PRIMA/Origins, X-ray probe).

KIDs for far-IR astronomy:

ID Lead PI Notes
158553 Caltech/JPL Jonas Zmuidzinas STRG NSTGRO fellowship, 2024-2028, TRL 2→3. Mid/far-IR KIDs targeting "3 orders of magnitude more sensitive than prior detectors." Zmuidzinas is the inventor of KID technology.
156364 UC Santa Barbara — MKID high-res spectrograph for space (TRL 2→3, 2023-2027). Multi-object spectrograph using 2D projection.
158436 U Chicago — mm-wave integral field spectrometer for line intensity mapping (TRL 2→3, 2024-2028). CMB/reionization science. Destination: outside solar system + Earth.

[158553] is the critical connection to the far-IR probe ecosystem: Zmuidzinas is already Co-I on SAT [157590] (Hailey-Dunsheath/Bradford KIDs, the highest-TRL far-IR KID project). His STRG NSTGRO grant advances far-IR KID sensitivity as a graduate research fellowship — simultaneously, his group is funded through APRA (QCD-KID hybrid [157536]) and completed SAT [157590]. The Caltech/JPL far-IR team operates across three funding channels at once.

X-ray TES and radiation-hardened superconductors:

ID Lead Notes
156367 U Wisconsin-Madison X-ray TES for sounding rocket; IGM/CGM diffuse gas. TRL 2→3, 2023-2027.
158655 MIT 3,720 views (highest in cohort). Radiation hardness study of superconducting detectors + electronics. TRL 2→4, 2024-2027.
158492 UT Dallas 3,718 views (nearly tied). Transparent superconductors for SNSPDs — optical transparency without sacrificing sensitivity. TRL 2→3, 2024-2027.
156365 UC Irvine Holey-Si thermopiles for planetary remote sensing; ice giants (Uranus/Neptune) down to 30K. TRL 2→3, 2023-2027.
158668 RIT Radiation-hard CMOS for single-photon counting at room temperature. 1,242 views. TRL 2→4, 2024-2027.

Why MIT [158655] and UT Dallas [158492] have 3,700+ views: Radiation hardness is the universally shared bottleneck for space deployment of any superconducting detector. Every KID, TES, and SNSPD program must qualify hardware against the space radiation environment. These two projects feed ALL astrophysics detector programs simultaneously.

Cluster B: Quantum and Novel Sensing (~5 projects)

ID Lead Description
158402 UT Austin Epitaxial vacuum cavities for chip-scale cold atom sensors (TRL 2→3, 2024-2028). Connects to cold-atom-quantum-sensing.md. Epitaxial growth replaces glass-blown cells — CubeSat-compatible manufacturing route.
156317 UT Austin Quantum Pathways Institute — quantum sensing for Earth climate science (TRL 2→4, 2023-2028). 1,399 views. txMismatch (ML predicts TX05.5.2 quantum comms).
158385 U Maryland NV-NMR biosignature detector — NV centers in diamond + hyperpolarization + microfluidics for single-cell life detection (TRL 2→3, 2024-2028). txMismatch (ML: TX06.3.1 medical).
158010 NYU 3D DNA nanomaterials for space biosensors — Watson-Crick base pairing for highly selective molecular recognition (TRL 2→3, 2024-2028). Destination: Earth only.

UT Austin cluster: UT Austin appears THREE times in TX08 STRG ([158402], [156317], [158471]), plus [118446] in TX17 and [118497] in TX12. The university has one of the broadest STRG cross-area footprints in this portfolio.

Biosignature detection: [158385] (NV-NMR) and [158010] (DNA nanomaterials) form a small cluster of novel life-detection sensor investments. Both TRL 2→3, pre-mission concept. Not connected to any active flight program in TechPort — speculative future capability building.

TX06: Life Support & Habitation — Human Health Research, Not ECLSS Hardware (16 projects)

Query: find_projects(program="STRG", technology_area="TX06", status="Active"), 16 results, snapshot 2026-04-04 (session 80)

Expectation vs. reality: Expected water processors, CO2 removal hardware, atmosphere management systems. Reality: human health research dominates — wearable diagnostics, biomanufacturing, biomedical countermeasures. TX06.3.1 Medical Diagnosis is the largest sub-area (5/16 = 31%). STRG funds academic foundations for crew health management; MCO funds the operational hardware NASA centers deploy. Compare tx06-life-support-eclss.md for the MCO ECLSS counterpart.

In-space biomanufacturing cluster — 3 projects (19%)

The most unexpected and coherent cluster in STRG TX06: three independent groups developing biological platforms for on-demand pharmaceutical production in space. Shared premise: a 3-year Mars mission cannot carry a sufficient pharmacy, and drugs degrade under radiation. Solution: engineer organisms to synthesize therapeutics in-flight.

ID Lead Organism Approach
156323 U Florida (Amor Menezes PI) E. coli, P. putida, lettuce Genetic circuits regulate pharmaceutical output in response to dynamic space conditions (radiation, microgravity). Most controllable; bacteria offer fastest production cycles but highest contamination risk. 679 views. 2023-2027.
158621 UC Davis (Karen McDonald PI) Duckweed (Lemna japonica) CRISPR-modified aquatic plant expressing ActRIIB-Fc — prevents muscle atrophy and bone density loss from microgravity. Dual-purpose: food + drug. Destinations: Moon, Mars, LEO. 425 views. 2024-2028.
156369 U Michigan (Libo Shan PI) Kalanchoe laetivirens ("Mother of Thousands") Succulent produces hundreds of clonal plantlets via asexual reproduction → self-replicating pharmacy. Antibodies, peptides, vaccines via Agrobacterium transformation. Drought-tolerant, fits existing space plant growth hardware. 662 views. 2023-2027.

Three platform strategies competing for the same niche: - Bacteria (UF): fastest production, most controllable, highest contamination risk - Aquatic plant (UC Davis): photosynthetic, dual food/drug, targets the most space-specific need (ActRIIB muscle atrophy countermeasure) - Succulent (Michigan): drought-tolerant = low water use; asexual reproduction enables self-sustaining pharmacy without Earth resupply

Connection to STRG TX07 biological ISRU: TX07 also has a biological cluster ([158634] Georgia Tech cyanobacteria + [156348] Texas A&M) targeting food/O₂ production from regolith. Both TX06 and TX07 bio clusters represent NASA STRG's bet on synthetic biology as life support infrastructure — pharmaceuticals (TX06) vs. food/O₂ (TX07). Together: 5 projects.

Connection to BLiSS: BLiSS [157839] (MCO) integrates plants, microbes, and crew in a 4-stage bioregenerative concept but does not currently include pharmaceutical biosynthesis. The STRG biomanufacturing cluster is the academic foundation for a potential future BLiSS pharmaceutical module.

Water recovery cluster — 3 projects

Two closing mid-2026: [118466] and [118467] end July–August 2026 with no visible pipeline to MCO. STRG water research and MCO operational hardware (UWMS TRL 7-8) are separated by a decade of maturation with no formal escalation mechanism in TechPort.

ECLSS hardware bridge — 1 project

158412 NC State (Sajjad Bigham PI): "Novel, Nature-Inspired, 3D-Printed Zeolite Topologies for Selective Carbon Capture"
TRL 2→3 | 2024-2028 | 614 views | Destinations: Moon, Mars, LEO

The only STRG TX06 project with a traceable connection to an operational NASA ECLSS subsystem. Current 4BCO2 scrubber uses randomly packed 2mm zeolite beads with three problems: gas maldistribution (preferred pathways reduce CO2 uptake), poor thermal management during regeneration, and low volumetric efficiency.

Solution: bioinspired bronchial-tree geometry printed by robocasting — monolithic 3D topology replaces random packing. Benefits: uniform gas flow, better heat transport, higher CO2 sorption capacity, better mechanical stability. Fundamental research needed on zeolite manufacturing and sorption physics before geometry optimization.

Direct ECLSS pipeline: Improved zeolite sorbent geometries could replace packed-bed canisters in the 4BCO2 scrubber. No MCO or GCD project is funding this at TRL 2 — NC State is the upstream feeder for a potential future ECLSS upgrade.

STRG TX06 vs. MCO TX06 — complementary layers

Feature STRG TX06 (16 projects) MCO TX06 (49 projects)
TRL range All TRL 2→3 TRL 6-8 (operational targets)
Institutions Universities NASA centers + industry
ECLSS hardware 1 project (NC State zeolite CO2) Full ECLSS systems (UWMS, OGA, AMCHX)
Biomanufacturing 3 academic concept projects 0 direct equivalents
View counts 393–804 1,000–5,000+ (UWMS 5,250)

STRG TX06 is the 10-15 year academic feedstock layer for crew health technology. The view count gap (STRG peaks at 804 vs. MCO operational hardware at 5,250) reflects the community's stronger attention on engineering hardware than academic foundations.

Taxonomy mismatch

Issue 29: 156352 MIT SuperLimbs — filed TX06.2.1 (Pressure Garment). The technology being developed is a wearable robotic system (TX04.4.1), not a pressure garment. The spacesuit integration context led a human to classify it under TX06; ML correctly predicts TX04. See field-completeness.md Issue 29.

TX17: Guidance, Navigation & Control (9 STRG active projects)

TX17 = Guidance, Navigation & Control (GN&C). Globally 400 projects across 32 programs; see tx17-gnc.md for full portfolio. The 9 STRG active projects are the academic research tier of a much larger investment area. All 9 STRG active TX17 projects are:

  • TX17.2.1 Onboard Navigation Algorithms: 8 projects
  • TX17.1.1 Guidance Algorithms: 1 project

Query: find_projects(program="STRG", technology_area="TX17", status="Active"), 9 results, snapshot 2026-04-04

158624 Robust spacecraft guidance under uncertainty CU Boulder Chance constraints, cislunar trajectories (TX17.1.1)

Pattern: CU Boulder has 3 TX17 projects. UT Austin has 2. All are computational/algorithmic — no hardware. All are TRL 2→3. Focused on: autonomous cislunar navigation, multi-body gravity (icy moons, cislunar), event-based sensors, robust optimization under uncertainty.

Note: The CARMEL project [184634] (GCD, TX10.4.3) has an ML prediction of TX17.2.1 — a human classified it as operational assurance but the ML sees it as navigation algorithms. This reflects a real ambiguity (CARMEL's reference mission involves autonomous navigation certification).

TX05: Communications & Navigation — Orbital Debris Cluster Dominates (6 projects)

Query: find_projects(program="STRG", technology_area="TX05", status="Active"), 6 results, snapshot 2026-04-04 (session 80)

Expectation vs. reality: Expected optical comms algorithms, network protocols, quantum comms theory. Reality: orbital debris mitigation (3/6 = 50%) is the dominant theme — not communications. TX05 contains the debris sub-area (TX05.6.3), and STRG is funding three independent academic approaches to the debris problem.

Sub-area breakdown

Sub-area Count Character
TX05.6.3 Orbital Debris Mitigation 3 (50%) Metamaterial deorbit, dust cloud avoidance, laser removal
TX05.5 Revolutionary Communications 1 (17%) Subwavelength integrated photonics for harsh environments
TX05.4.2 Revolutionary PNT Technologies 1 (17%) Quantum optimal photonic processing
TX05.1.6 Optimetrics 1 (17%) AR&D optical maneuver detection — mislabeled TX04.5.2

Orbital debris cluster — 3 projects (already in tx05-comms-nav.md)

These three were identified in session 65 as the STRG debris spectrum (track→avoid→remove). Full analysis in tx05-comms-nav.md; brief summary here:

ID Lead Approach Views Notes
158717 Auburn Metamaterial particles that change albedo/charge → improve trackability of sub-10cm debris 814 Mar 2024–Feb 2027
156380 Virginia Tech Just-in-time collision avoidance via targeted dust cloud deployment from orbital platform 1,345 Oct 2023–Oct 2026
156377 West Virginia U Reconfigurable space-based laser network for rapid debris removal 1,386 (highest in TX05 STRG) Oct 2023–Oct 2026; txMismatch (ML: TX08.1.5 Lasers — borderline; TX05.6.3 correct for application)

View counts (1,345–1,386) far exceed the TX06 cohort range (393–804) — the orbital debris problem has broader community attention than life support research.

Comms/photonics — 2 new projects

ID Lead Technology Notes
156343 Vanderbilt Deep subwavelength integrated photonics PICs for harsh environments Enables radiation-hard, thermally stable PICs for space optical comms and sensing. TX05.5 Revolutionary Comms. 463 views. 2023-2027.

[156355] U Arizona is the most conceptually distant STRG project in TX05 — quantum information theory applied to communications. "Orders of magnitude improvement over current communications and sensing technologies" if photonic optimal receivers are realized. TRL 2→3 is extremely early for quantum comms. Connects to the DSQL project documented in tx05-comms-nav.md (JPL quantum link, 10-year horizon).

Mismatch

Issue 30: 118518 UT Austin — filed TX05.1.6 (Optimetrics). The project is about autonomous rendezvous and docking using optical maneuver detection algorithms — RPOD (TX04.5.2). The "optical" in the title caused a human to file it under TX05 (optical = comms context). ML correctly predicts TX04.5.2. See field-completeness.md Issue 30. Ends Aug 2026.

TX11: Software/Computing — Nearly Absent (3 projects, 1.5%)

Query: find_projects(program="STRG", technology_area="TX11", status="Active") — 3 results, snapshot 2026-04-04 (resolved session 82)

Only 3 active STRG projects in TX11 — and all 3 have txMismatch=Yes. The surprise: none are "software" in the traditional computing sense. All are mission analysis tools or astrodynamics algorithms.

ID Project Lead Sub-area End
118462 Keyhole-Based Planetary Defense Impact Risk Assessment UIUC TX11.3.3 Model-Based Systems Eng. Aug 2026
118386 Numerical Methods for Distributed Spacecraft Coverage UT Austin TX11.5.1 Mission Architecture Tools Jul 2026
118457 Rapid Computational Methods for DSM Coverage Analysis UCF TX11.5.1 Mission Architecture Tools Jul 2026

What they actually are: - [118462] UIUC is a planetary defense project — keyhole corridor analysis for asteroid deflection trajectory design. Classified TX11 because it builds trajectory software; substantively TX05.6 (planetary defense/orbital debris) or TX09 orbital dynamics. - [118386] and [118457] are competing satellite coverage analysis algorithms — near-identical problem statement (fast numerical methods for distributed spacecraft spatiotemporal coverage), different institutions. Both TX11.5.1. Views 579 vs 411 — similar interest levels. Either a deliberate competition or parallel funding of the same gap.

Key insight: STRG TX11 = astrodynamics and mission analysis tools, not general computing or AI/ML. The near-absence of TX11 in STRG confirms that: 1. NASA's STRG doesn't fund general software research (NSF domain) 2. Astrodynamics algorithms end up classified TX11 only when they're framed as "tools/methodologies" rather than physics (TX09) or GN&C (TX17) 3. All 3 projects' txMismatch=Yes means the human TX11 classifications are likely wrong — the ML probably assigns them to TX09, TX17, or TX05

All three end mid-2026 with no visible follow-on.

Cross-reference: TX11 Software page documented the AI/ML valley of death at TRL 6→7 — STRG's near-zero presence confirms academic AI/ML research has no formal STRG pathway to NASA flight software validation.

Cross-Cutting Observations

STRG = Computation First, Hardware Second

Across all TX areas, STRG's active portfolio skews toward simulation tools, algorithms, and modeling frameworks rather than hardware prototypes. This is visible in: - TX09: ~13/24 in "Integrated Modeling and Simulation" sub-area - TX12: 5-6 in "Computational Materials" and "Digital Transformation Technologies" sub-areas - TX17: 9/9 are pure algorithm research

This reflects the academic constraint: universities can build models and algorithms; hardware development requires infrastructure SBIR and industry partners provide.

Elastocaloric Bets: 3 Universities, 2 TX Areas

ID Lead TX Notes
158568 Texas A&M TX14.X: Other Thermal Mgmt STRG, TRL 2→4, Jan 2024–Jan 2027
158417 UIUC TX14.X: Other Thermal Mgmt STRG, TRL 2→4, Jan 2024–Jan 2027, txMismatch=Yes (ML→TX12)
158653 Iowa State TX12.1.7 Special Materials STRG, TRL 2→3, Mar 2024–Feb 2027, txMismatch=Yes (ML→TX14)

Three bets on elastocaloric (solid-state mechanocaloric) cooling, classified under two TX areas. Texas A&M and UIUC framed as cooling systems (TX14); Iowa State framed as advanced materials (TX12). ML resolves in opposite directions — UIUC flagged mismatch toward TX12, Iowa State toward TX14. The txMismatch flags pointing in opposite directions confirm this is a genuine human framing ambiguity, not a clear-cut error. Texas A&M and UIUC also target TRL 4 (plan hardware demo), while Iowa State targets only TRL 3 (materials study). All three view counts are anomalously high (1,328–1,385): solid-state cooling without refrigerants has broad appeal.

Synthetic Biology: A 5-Project Cross-Area Portfolio Bet

STRG contains 5 synthetic biology projects split across two TX areas:

TX06 — Pharmaceutical biomanufacturing (3 projects): - 156323 UF: E. coli/P. putida + lettuce — genetic circuits for pharmaceutical production - 158621 UC Davis: CRISPR duckweed (Lemna japonica) — ActRIIB-Fc for muscle atrophy - 156369 Michigan: Kalanchoe "Mother of Thousands" succulent — self-replicating pharmacy

TX07 — Biological ISRU and food production (2 projects): - 158634 Georgia Tech: Cyanobacteria for Mars bioproduction (O₂ + feedstocks from CO₂) - 156348 Texas A&M: Microbial soil enrichment for Mars aeroponic agriculture

These 5 projects constitute an emergent synthetic biology portfolio: TX07 = food and O₂ from biology; TX06 = drugs from biology. Same philosophy — use engineered organisms as life support infrastructure — applied to two different resource gaps. All TRL 2→3. No explicit coordination visible in TechPort (different PMs: TX06 = Settles/Orourke; TX07 = Roberson/KSC). But the co-investment reflects an implicit NASA STRG bet that biology is a viable engineering path for deep-space self-sufficiency.

See also: bliss.md for the MCO bioregenerative system concept (integrates plants/microbes for water + O₂, currently separate from the pharmaceutical track).

Refractory Metal AM: An Implicit NTP Materials Pipeline

WPI's refractory powder production project [158508] explicitly targets NTP and NEP propulsion systems — even though both TDM NTP/NEP programs were terminated Dec 2025 (see nuclear propulsion surprise). STRG continues funding the materials science foundations even after the program-level investment ended. This is either: - Pre-competitive materials research with dual-use potential (e.g., for SBIR companies), OR - A lag artifact — the grant was awarded before Dec 2025 terminations and runs to 2028

Program-Level Escalation Pathways (added session 82)

Expectation: STRG academic grants would have clear pipeline links to GCD/MCO/SBIR. Reality: pathways are largely inferred from PM names and center affiliation — TechPort has no formal STRG→GCD citation mechanism.

Two structural mechanisms carry STRG TRL 2-3 results forward:

Track 1 — STRG physics → GCD engineering (shared PM center):

The most traceable pathway. PM name is the primary evidence of intentional pipeline:

STRG Cluster Key Example Evidence Downstream Program
RDRE physics UIUC [118450] (5,870 views) PM Hugh Perkins (GRC) = same center managing GCD RDRE TDM [158559] GCD TDM [158559] (MSFC+AFRL integrated system)
PSI / plume-surface JHU [118454], Auburn [158007], Berkeley [156331] Topic alignment to GCD SCALPSS/STRATFI lander programs GCD lunar EDL (SCALPSS TRL 7, STRATFI commercial)
TX06 zeolite CO2 NC State [158412] (NC State → bronchial-tree 3D zeolite) Only STRG project with traceable ECLSS subsystem line (4BCO2 scrubber) MCO ECLSS (no formal link — relies on independent discovery)
TX07 cyanobacteria Georgia Tech [158634] PM Luke Roberson (KSC) = NASA's biomanufacturing PM Potential future GCD/TDM (no TRL 4+ biological ISRU program exists yet)

Track 2 — STRG component/material → SBIR or SAT qualification:

STRG Cluster Key Example Mechanism Downstream
Far-IR KID detectors Zmuidzinas NSTGRO [158553] + radiation hardness MIT [158655] Academic groundwork → SAT grants (Bradford TRL 4→6, [157590]) → CT4LT HWO maturation SAT → CT4LT → HWO instrument
AM certification CMU IMQCAM [156318] (5,348 views = #1 STRG TX12) Certification standards framework → SBIR companies seeking flight qual SBIR AM companies
Dust mitigation 182xxx cohort 4 projects (2025) Novel approaches → SBIR companies providing Artemis surface hardware GCD/SBIR surface systems
TX12 ISM welding U Chicago [182205], UT Dallas [182219] Digital twins for in-space welding → Lockheed ISAM Joining Demos [156390] and MSFC laser welding TDM ISAM [156390]

What's NOT escalating (weak or absent pathways):

  • TX11 Software (3 projects): Too abstract; no GCD/MCO equivalent at TRL 4+. AI/ML research lacks a formal STRG→flight-software path.
  • TX17 GN&C algorithms: CU Boulder (3 projects), UT Austin (2) — all TRL 2→3 computational. No GCD navigation pick-up documented. Knowledge goes to publications.
  • TX10 Autonomy (6 projects): Academic fault-resilience and behavior research. MCO/GCD operate autonomy at TRL 6-8 (EIOAR, CARMEL) independently.
  • TX05 Debris mitigation (3 projects): No MCO/GCD debris "engineering" equivalent — orbital debris is managed operationally (CARA, USSF), not via GCD tech programs.
  • TX06 Biomanufacturing pharma cluster (3 projects): The most ambitious STRG bet with the weakest escalation path. No NASA equivalent at TRL >2 for space pharmaceutical production. If these 3 projects reach TRL 3, there is no waiting GCD program to receive them — a new program would need to be created.

Structural limitation — TechPort visibility gap:

STRG grants cannot record Transitioned_To during their active period. The escalation analysis is PM-name based, not TechPort-structure based. The real pipeline from STRG paper → SBIR solicitation → GCD pick-up is largely invisible in TechPort. This is one of the three undercount mechanisms documented in outcome-tracking.md.

The biological cluster as structural outlier:

The 5-project synthetic biology portfolio (3 pharma in TX06 + 2 ISRU in TX07) is the only STRG cluster that targets a fundamentally new engineering capability with no current higher-TRL equivalent. All other clusters (RDRE, AM, detectors, EP) have a GCD or SAT program already operating at TRL 4+. Biology-based life support does not. This makes the synthetic biology cluster both the most ambitious and the highest-risk STRG bet — it requires creating a new program track, not just feeding an existing one.

Institution Concentration (added session 82)

University Active STRG Projects (est.) Primary TX Areas
University of Michigan 5+ TX01 EP exclusively (Hall thruster dynasty)
CU Boulder 5 TX09 CFD (ACCESS) + TX17 nav algorithms (3) + TX08
UT Austin 4–5 TX17 + TX08 quantum sensing + TX12 AM
Georgia Tech 4 TX01 JANUS + TX07 bio ISRU + TX09 + TX17
Carnegie Mellon 2 TX12 AM certification (IMQCAM + fatigue)
Texas A&M 2+ TX06 bio pharma + TX07 ISRU + TX14 elastocaloric
Stanford 2+ TX01 RDRE spray dynamics + TX17 + TX09

Patterns: Michigan has the most concentrated STRG presence (all EP) — consistent with their historical Hall thruster dominance. CU Boulder is most prolific across TX areas (CFD + GN&C). Georgia Tech is most cross-cutting (propulsion + ISRU + navigation). CMU is the deepest single-topic investment (AM certification is their explicit specialization).

No HBCU or MSI has a major STRG presence in the active portfolio — STRG MSI/HSI representation comes primarily from TX07 (UTSA [158209] HSI for Apollo regolith bricks; Texas A&M [156348] MSI for ISRU agriculture) and TX09 (University of New Mexico in the ACCESS consortium). The synthetic biology pharma cluster has no MSI lead PIs despite the medical/health research framing.

TX03: Power — PSR Power Access (13 projects)

Query: find_projects(program="STRG", technology_area="TX03", status="Active") — 13 results, snapshot 2026-04-04

Organizing theme: Permanently Shadowed Regions (PSRs) are the central challenge. All 4 183xxx cohort projects (May 2025, Deans/Nguyen PM) explicitly target PSR power access. The pre-183xxx projects converge on the same constraint from different angles: radiation-hard solar cells for outer-planet/cislunar missions, cryogenic power electronics for extreme cold, laser power beaming into shadow.

Key findings

Philip Lubin — directed energy ecosystem. Project Moonbeam [118528] (STRG TX03, laser power beaming for lunar PSRs, TRL 3→5, ends May 2026) is by Philip Lubin (UCSB) — the same PI as NIAC Phase III "PI Defense" [158596] (planetary defense via bolide pulverization) and diffractive solar sailing context. Lubin's underlying platform is a modular, scalable directed energy array that he applies to multiple mission contexts: power beaming, planetary defense, and propulsion. The STRG Moonbeam result feeds the same laser hardware ecosystem as the NIAC defense work. Cross-reference: pi-defense.md, diffractive-solar-sailing.md.

Geoffrey Landis — cross-program power extremes connector. Moonbeam's PM is Geoffrey Landis (GRC). Landis is also co-investigator on TRC [158706] (NIAC, outer planet power via thermoradiative cell, RIT/GRC). These are completely different power problems — lunar PSR laser beaming vs. outer solar system radioisotope power — but both address the same meta-challenge: delivering power to environments with no viable sunlight. Landis bridges the two domains as the GRC power-extremes research coordinator. See topics/outer-planet-access.md.

UIUC radiation-hard solar cells [158490] — 1,618 views. Strain-balanced superlattices to maintain lattice coherence in inverted metamorphic multi-junction cells under radiation damage. At 1,618 views this is the highest-viewed project in the TX03 cohort, suggesting the solar cell radiation-hardening problem is widely tracked. Feeds any mission using solar power in radiation-intensive environments (cislunar, Europa, Mars transit).

Cryogenic power electronics cluster. Three projects address extreme cold: Clemson [118479] (semiconductor characterization at cryogenic temps, TRL 3 — only TX03 project already at TRL 3), UT Austin [156362] (on-chip magnetics for compact converters), UC Berkeley [183700] (piezoelectric conversion). Together these constitute the power conditioning layer required by PSR assets — the regolith mining and sample collection equipment that would operate in -230°C PSRs needs power electronics that won't fail.

2026 closures: 4 projects end this year. [118498] UC Berkeley thermionic (Aug), [118528] UCSB Moonbeam (May), [118529] RIT receivers (Jul), [118460] CU Boulder charge sensing (Aug). None have visible outcomes in TechPort yet. Moonbeam is highest-priority for follow-up — TRL 3→5 target in a closing program.

TX mismatch rate: 4/13 = 31%. Much higher than SBIR baseline (~4%). The PSR power cluster spans TX03/TX07 conceptually (power for ISRU operations), causing 2 of the 4 mismatches. The charge sensing project [118460] is a clear miscategorization — it belongs in TX04.5 (rendezvous proximity ops), not TX03 (power).

Escalation gap: No GCD-level laser power beaming project exists after the BET assessment study [184670] ends April 30, 2026. STRG Moonbeam (TRL 3→5) has no visible GCD or SBIR receiver program. If Moonbeam reaches TRL 5, the next TRL step is unfunded.

TX04: Robotics — Extreme-Environment Access + Cislunar RPOD (18 projects)

Query: find_projects(program="STRG", technology_area="TX04", status="Active") — 18 results, snapshot 2026-04-04

Organizing theme: STRG TX04 is a two-cluster portfolio: (1) extreme-environment surface mobility targeting icy worlds (Enceladus, Europa) and lunar PSRs — soft robots, ice grippers, legged locomotion, cryogenic actuators; (2) cislunar RPOD mathematics — safe rendezvous trajectories and capture dynamics for in-space servicing. All 18 projects are TRL 2→3, university-led. No hardware above bench-scale.

Key findings

CU Boulder RPOD cluster. Two TX04 projects ([158555] safe rendezvous + [158399] capture dynamics) from CU Boulder, both cislunar. Combined with CU Boulder's TX17 portfolio (Scheeres [2 projects] + McMahon [1 project]), CU Boulder has 5 concurrent STRG grants in cislunar GN&C/RPOD — the most concentrated STRG investment in the in-space servicing problem. Both TX04 projects end 2028, suggesting sustained funding.

UC Merced dry film lubricants [158635] — the cryogenic actuator problem. Current rover actuators require heaters to stay above −130°C. PSRs reach −230°C, and lunar night reaches −180°C. This is the only STRG project directly targeting the heaterless actuator problem — lubricants that maintain viscosity and tribological properties at PSR temperatures. Directly enables surface rovers operating without heater-power overhead. Ends 2028 — no follow-up program visible in GCD.

Icy world mobility cluster. Harvard vine robots [156370] + UC Berkeley ice grippers [156321] + UC Berkeley legged [158761] + Northeastern snake [158639] = 4 projects on extreme access. All target crater interiors, caves, and icy world surfaces where conventional wheeled rovers fail. This is a coherent STRG bet that rigid robots can't access Europa vents or lunar PSR caves — soft and multi-modal robots might.

TX mismatch rate: 5/18 = 28%. TX04 is used as a broad "space robotics" bin but the content spans AI/navigation, materials, software, and structural dynamics. Specific mismatches: - [156347] UT Austin → TX17.2.3: cislunar orbit determination (navigation, not robotics) - [156335] Stanford → TX17.2.3: surface mapping using NeRF (navigation perception, not hardware robotics) - [118436] Yale → TX12.1.8: soft robot skins = material science as much as robotics - [156325] U Minnesota → TX15.1.3: deployable structures = aeroelastic/structural dynamics - [156372] USC → TX11.1.7: formal safety verification = software methodology

MIT 4D Sensing [158368] — high-value perception project. 1,596 views and a 4-year grant (2024–2028). Addresses optimal sensor deployment for reconstructing dynamic 3D scenes under computational/mass constraints — the fundamental challenge for rover surface science. Builds toward mission scenarios like Mars recurring slope lineae monitoring and lunar volcanic site characterization.

Escalation gap — same structural problem as TX03. The bimodal TRL gap (STRG 2-3 vs GCD 5-9) is clearest in TX04. Harvard vine robots, UC Berkeley ice grippers, and UC Merced dry lubricants have no waiting GCD program. The STRG TX04 investment advances capabilities that current GCD programs (HI-RATE, LAUNCHER, Mobility Coordinator — all for Artemis wheeled rovers) don't target. The icy world access cluster is 8–15 years from a mission that would test these technologies.

Open Threads

  1. What are the 3 TX11 STRG projects? RESOLVED (session 82) — All 3 are astrodynamics/mission analysis tools (not general software): UIUC [118462] planetary defense keyhole analysis (TX11.3.3), UT Austin [118386] + UCF [118457] competing distributed spacecraft coverage algorithms (both TX11.5.1). All 3 have txMismatch=Yes. All end mid-2026.
  2. Lunar dust mitigation cohort (182xxx): All 4–5 projects awarded ~2025. Was there a specific BAA solicitation? What performance targets were set?
  3. CU Boulder TX17 dominance: 3 navigation algorithm projects from one university. CU Boulder's PI team seems to have a strong relationship with NASA GN&C programs.
  4. TX17 global scope: RESOLVED — 400 projects across 32 programs, SBIR/STTR dominant (55%), see tx17-gnc.md.
  5. Iowa State elastocaloric [158653] vs Texas A&M [158568] + UIUC [158417]: Are these independent groups or aware of each other? Results could potentially be coordinated (unlikely — STRG grants are competitive). The mutual txMismatch (ML sees each group's work as the other's TX area) confirms genuine framing ambiguity.
  6. STRG TX03 Power. RESOLVED (session 83) — Full section written above. 13 projects; PSR power access is organizing theme; laser power beaming cluster (Moonbeam/RIT) ends 2026 with no GCD follow-on; UIUC radiation-hard cells [158490] highest-viewed (1,618); Lubin directed energy ecosystem spans TX03 + NIAC PI Defense.
  7. STRG TX04 Robotics. RESOLVED (session 83) — Full section written above. 18 projects; two-cluster portfolio (icy-world mobility + cislunar RPOD); 5/18 TX mismatches (28%); UC Merced dry lubricants [158635] = only heaterless actuator project; CU Boulder 5-project cislunar cluster; bimodal TRL gap persists with no GCD bridge.
  8. TX03+TX04 escalation pathways. RESOLVED (session 83) — Both TX03 and TX04 have structural escalation gaps. Laser power beaming (Moonbeam TRL 3→5) has no GCD receiver. Icy-world mobility (vine/grippers/legged) has no GCD receiver — GCD surface mobility targets Artemis wheeled rovers only. The only TX04 cluster with potential near-term escalation is CU Boulder RPOD (cislunar in-space servicing is an active GCD/TDM interest).
