Created: 2026-04-06 (session 31)

Portfolio Overview

Active projects: 68
Programs: STRG 30 (44.1%), SBIR/STTR 18 (26.5%), FO 7 (10.3%), GCD 5 (7.4%), MSFC IRAD 3 (4.4%), EPSCoR 2 (2.9%), TDM 1 (1.5%), NIAC 1 (1.5%), AAVP 1 (1.5%)
TRL distribution: TRL 2: 24 (35.3%), TRL 4: 16 (23.5%), none/0: 15 (22.1%), TRL 3: 9 (13.2%), TRL 5-6: 4 (5.8%)
Max TRL: 6 (only 2 projects at this level)
Query: find_projects(technology_area="TX12", status="Active") + portfolio_aggregate(group_by="program", filter={"primaryTx":"TX12","status":"Active"}), snapshot 2026-04-04

Surprise: TX12 is far larger than TX10 (68 vs 11 active projects) and covers a wider scope — materials science, structures, and manufacturing all bundled together. The TRL ceiling is strikingly low: no active TX12 project is above TRL 6. This is consistent with the STRG-dominant funding mix (academic, TRL 2-3 focus).

Theme 1: In-Space Manufacturing (ISM) — GCD Cluster

A cluster of 5 new GCD projects in 2025 signals renewed NASA investment in in-space manufacturing:

Project ID Lead TRL Period
Space Recycling and Manufacturing 184649 MSFC — 2025-05 to 2026-04
AAMIDRSS (AM Inspection, Detection, Repair) 184648 LaRC — 2025-04 to 2028-06
Continuous Manufacturing of Rollable Elements 184657 LaRC — 2025-09 to 2026-09
ISM-ASTRO 184656 MSFC — 2025-09 to 2026-09
Space Habitat Structures with AM 147017 Big Metal Additive — 2023-07 to 2026-12

All GCD ISM projects share PM: Mary J. Werkheiser (Program Director) and Mark N. Thornblom (Program Manager). This is a coordinated portfolio, not independent awards.

Space Recycling and Manufacturing ([184649]): Focuses on in-space recycling to reduce resupply mission frequency. Destinations: Moon, Mars, beyond. Ends April 2026.

AAMIDRSS ([184648]): Automated defect detection and repair for wire-based additive manufacturing in space — sensors mounted on AM tool. Ends June 2028 (longest horizon in the GCD ISM cluster).

Continuous Manufacturing of Rollable Elements ([184657]): Novel process for large thin-shell composite structures that can be rolled/folded for compact stowage. Source material: thin-ply carbon fiber + thermoplastic. LaRC PI: Juan Fernandez. Short duration (1 year, ends Sept 2026).

ISM-ASTRO ([184656]): Study + industry engagement to guide future ISM investments. Focus: metals ISM, verification technologies, recycling, electronics ISM, modeling. Explicitly commercial-development oriented. Ends Sept 2026.

Space Habitat Structures with AM ([147017]): Big Metal Additive (Colorado), aluminum AM for habitat structures (docking/berthing rings). Claims 95% reduction in lead time vs forged machined parts (from 12-36 months to ~weeks). GCD project, ends Dec 2026.

Theme 2: Additive Manufacturing Certification — CMU IMQCAM

Institute for Model-Based Qualification & Certification of Additive Manufacturing ([156318])
STRG, Carnegie Mellon University + Johns Hopkins. TRL 2→4. 2023-2028. 5,348 views — highest in TX12.

IMQCAM = multi-institution center (spans CT, MD, OH, PA, TN, TX, VA) developing computational models for certifying metal AM parts in spaceflight applications. PIs: Somnath Ghosh + Anthony Rollett (both CMU). Focus: process-structure-property linkage for powder-bed fusion parts.

Significance: Metal AM parts in spaceflight currently require extensive empirical testing for each part/machine/material combination. Model-based certification could dramatically reduce this cost. This is the foundational research enabling the GCD ISM hardware programs.

Theme 3: FO In-Space Manufacturing Experiments

Flight Opportunities runs 7 TX12 projects that test manufacturing processes in reduced-gravity parabolic flights and eventually ISS:

Project ID Lead TRL Target Notable
SEADS (Space Enabled Advanced Devices and Semiconductors) 155248 MSFC 6 Semiconductor printing in microgravity
Evaluation of Pantographic Structures 182833 Carnegie Mellon 6 Deployable load-bearing digital twin
MoS2 Microgravity Annealing 184143 Goeppert LLC 5 Radiation-hardened electronics
In Space Dry Printing Electronics 158562 Auburn 6 Multi-material electronics printing
Reduced-Gravity Laser Welding 155259 MSFC 6 Computational model validation
FAME (Fluids at Altitude Mixing) 155247 Redwire Space 6 Fluid mixing in microgravity
Novel Property Measurement for ISM 106649 U of Florida 6 Material property measurement technique

SEADS Deep-Dive ([155248])

SEADS = On-Demand Manufacturing of Electronics (ODME). Goal: electrohydrodynamic (EHD) inkjet printing of semiconductor devices on ISS.

Why microgravity helps: EHD printing produces better trench filling conformity and fewer voiding defects in sub-µm semiconductor manufacturing under zero-g. Current manufacturing requires costly facilities, hundreds of lithography masks, and complex etch/deposition/growth process flows. EHD is maskless, contact-free, and etching-free.

Partners: Intel, NAU (Northern Arizona University), Fujifilm, TEL (Tokyo Electron Limited), Axiom Space.

Flight history: - Nov 2023 + Feb 2024: Parabolic flights — did not achieve goals, got learning - March 5, 2024: Demonstrated EHD printing of insulator and semiconductor on conducting material — first success

Status: TRL 4, ends April 30, 2026 (target TRL 6). Will likely close near TRL 4-5.

Confidence: speculative on TRL achievement, suggestive on technical approach (one flight demo completed)

Theme 4: In-Space Assembly and Joining — Full Ecosystem

Session 48 deep-dive. Full topic page: topics/isam-joining.md

The in-space joining portfolio spans five technology approaches and multiple programs. Lockheed Martin is the dominant industry player, with three concurrent NASA collaborations.

TDM anchor: Joining Demonstrations In-Space 156390
Lockheed Martin (Palo Alto CA), TRL 4→8 target, Oct 2026. 4,769 views. PI: Robert Biggs.
Scope: structural + electrical + fluid joining — the three categories needed to fully assemble a spacecraft on-orbit. Heritage: CIRAS [94090] (2016-2018, Northrop Grumman, TALISMAN robot arm, TRL 4→5) → Lockheed ACOs (SMART-C + FABORM, 2023-2025) → Joining Demos.

TRL 8 concern (confirmed): As of Feb 2026, still TRL 4 with 8 months remaining. CIRAS reached only TRL 5 with a similar scope. TDM pattern (MMPACT, Mason, CDM, LEAPFROG, LOXSAT, PRO-TP) = systematic 2–3 level TRL shortfall. Prediction: Joining Demos closes at TRL 5–6, not 8. Confidence: suggestive.

Lockheed joining portfolio (all three programs):

Project Program Technology Period Status
SMART-C 146998 GCD ACO Thermoplastic composites (order-of-magnitude improvement target) 2023–2025 Completed
FABORM 147009 GCD ACO FSW blank-forming for large metallic structures 2023–2025 Completed
Joining Demos 156390 TDM Structural+electrical+fluid joining 2023–2026 Active TRL 4→8

Boeing habitat application 147006: Complex Curvature Retractable Pin Tool FSW, GCD, Boeing. Goal: weld aluminum in complex 3D geometries for "docking ports, hatches, windows." Boeing explicitly plans to implement in their habitat product line (Orbital Reef context). Ground manufacturing capability, not in-space joining.

MSFC government complement — laser welding: - IRAD suborbital LBW 157858: Hardware prototype built FY24 (conformal vacuum chamber + laser + weld camera), TRL 4→5. Needs suborbital flight for TRL 6. - Parabolic flight LBW 155259: First microgravity+vacuum laser weld (Aug 2024), TRL 4→6 FO. - Swarm robotics welding 184352: UTEP+MSFC autonomous robotic welding, TRL 1→4, completed Jan 2026. - All three MSFC welding programs PM'd by Dankanich.

Alternative approaches: - Reversible adhesive: ATSP Innovations 113487, TRL 6 (highest in space joining), SBIR, no GCD/TDM follow-on visible. - Solar-powered orbital welding: Blueshift/Outward SO-WARM 154537, TRL 4–5, Fresnel lens concentrator approach. - ICME modeling: CFD Research 158612, active SBIR, TRL 3→5, physics-based weld quality prediction pipeline.

Theme 5: Lunar Surface Construction Materials

Several SBIR and one GCD project targeting lunar surface structural needs:

Project ID Lead TRL Focus
Brickbot Lunar Surface Demo 182898 Astroport Space Technologies 4→6 Brick-laying robot, subscale demo (Active through Jan 2027)
C-Tower 158752 Ceres Robotics 3→5 Mobile, retractable 50-kW solar array mast
Lunar Truss Design and Construction 158718 Bond Technologies 4→5 Structural truss construction
Novel Lunar Landing Pad Reinforcement 182908 Linc Research 5→5 Landing pad structures
LEWC (Lunar Extreme Water Container) 158618 Moonprint Solutions 4→6 Water containment for extreme lunar conditions

C-Tower ([158752]) — Notable: Ceres Robotics, TRL 3→5 SBIR. Mobile, retractable truss mast for relocatable 50-kW vertical solar arrays on the lunar surface. 2,314 views. This is a structural solution to the lunar power distribution problem — instead of fixed solar infrastructure, deploy and move it as needed.

Moonprint Solutions ([158618]) — Also appears in Mycotecture team (David Cadogan as inflatable expert). The same small company is building water containers and advising fungal habitat development.

HELCoW (158264) — ICON Technology, SBIR Phase I, completed Feb 2025: Direct diode laser (DDL) for cleaning and conduction welding of aluminum and stainless steel in vacuum environments. TRL 2→3. Applications: orbital assembly, lunar surface construction, spacecraft repair and recycling. CLPS-payload compatible. PI: Brian Vattiat (ICON Build). TX Mismatch: human=TX12, ML=TX08.1.5 Lasers (both partially correct — it's a laser used for construction). Note: MSFC FO project [155259] (Reduced-Gravity Laser Welding) provides the government-funded computational model parallel to HELCoW's commercial hardware. ICON Technology is the primary contractor in MMPACT [116319] (GCD, surface construction) and is now diversifying into orbital construction via HELCoW. See topics/lunar-surface-construction.md for full context.

Theme 6: Dust Mitigation Materials — STRG Investment

Strong STRG focus on lunar dust mitigation coatings and surface treatments. The January 2025 cohort (182xxx IDs) produced 4 dust mitigation projects with identical start dates (2025-01-27, end 2028-01-26, TRL 2→4), plus an earlier 2024-start project:

Project ID Lead Approach Views Start
Doped-YSZ ceramic coatings 158637 Embry-Riddle Passive wear-resistant lunar dust coating 399 2024-08
Crumpled nano-ball coatings 182203 UC Irvine Deformable nanocoatings with mechanical energy absorption, adaptable adhesion 1,253 2025-01
Hierarchical dust-mitigating nanostructures 182204 see live record Van der Waals adhesion mechanisms for dust removal 630 2025-01
Anisotropic structured surface 182220 U Central Florida Anisotropic electrostatic-dissipative coatings 617 2025-01
Bioinspired surface textures 182221 U Arkansas Bio-mimetic dust repulsion (lotus leaf, shark skin) 649 2025-01

(Note: [182205] Weld-ASSIST and [182219] lunar metal welding computational model are also 182xxx January 2025 STRG projects in TX12 but cover in-space welding — see isam-joining.md)

The 4 dust mitigation approaches span different physical mechanisms: 1. [182221] Bioinspired textures — surface microstructure mimicking natural hydrophobic/anti-adhesive surfaces 2. [182204] Hierarchical nanostructures — engineering Van der Waals forces at nanoscale to prevent particle adhesion 3. [182220] Anisotropic coatings — directional surface structures with electrostatic dissipation 4. [182203] Crumpled nano-ball coatings — deformable nanoparticle coatings that absorb mechanical energy from impacting dust

[182203] view count (1,253) is notably higher than others — the crumpled nano-ball concept attracts more attention. Full record (session 60): PI = Nam Sungwoo (UC Irvine); materials are 2D nanosheets (MoS₂, graphene, MXenes) crumpled into nano-balls that form corrugated coatings minimizing dust contact area; also electrostatically dissipative, neutralizing lunar dust charge. Target: 90% dust clearance. Start date 2025-01-01 (one month earlier than the other 182xxx Jan 2025 projects). Under same Deans/Nguyen program contacts.

ML mismatch pattern: All 4 January 2025 dust mitigation projects have txMismatch=Yes. Human classified as TX12 (materials science); ML predicted TX07.2.5 (Particulate Contamination Prevention). The ML focuses on the application context (dust mitigation = contamination), while humans correctly identify the core research as materials science (TX12). This is the inverse of the PSR power mismatch (Issues 16-17 in field-completeness.md) — there the ML fires TX07 when the human classified TX03. Here: ML fires TX07 when human classified TX12. PSR/lunar-dust framing consistently confuses the classifier toward TX07.

All dust mitigation projects are early-stage STRG TRL 2→3 or 2→4. The duplication of approaches is deliberate — portfolio search for the right material solution before committing to engineering development.

Theme 7: Advanced Structural Materials — STRG

Dominant STRG themes:

Refractory alloys (3+ projects): - High-entropy refractory alloys via ML discovery — Cornell ([156350]) - Refractory metal powder production — WPI ([158508]) - Oxidation protection of refractory metals — UC Irvine ([158628])

All TRL 2→3. These feed nuclear propulsion and high-temperature propulsion applications (connection to TX01 refractory needs).

Extreme-temperature ceramics: - Ultra High-Temperature Ceramics (UHTC) composites — MIT ([156339]), TRL 2→3

Carbon nanotube composites: - CNT+regolith for lunar habitats — Syracuse ([158661]) - CNT optimization via ML — Virginia Commonwealth ([156341], 1,373 views)

Shape memory alloys: - NiTi60 bearings in cryo-vacuum — FSU ([118451]) - Low-hysteresis SMAs for actuation + thermal management — U Michigan ([156360])

Elastocaloric refrigeration ([158653]): Iowa State, STRG, TRL 2→3. Elastocaloric = stress-induced heating/cooling in SMAs. Could replace vapor-compression cooling for space applications. 1,328 views — niche but interesting for thermal management.

RTG thermoelectrics: Grain boundary engineering of RTG thermoelectrics — Northwestern ([118371]), TRL 2→3. Connection to RPS program.

Regolith ISRU for additive manufacturing: 158429 Rice University (PI: Fred Higgs), TX12.4.1, TRL 2→3, Aug 2024–Jul 2026, 1,595 views — highest of any active STRG TX12 project. Uses binder jet 3D printing (BJ3DP) with regolith simulants as feedstock — rheometry characterization → DEM digital twins → AI-accelerated simulation → physical validation. Dual-destination: Moon and Mars. Short 2-year project (not the typical 3-year STRG). High views reflect public appeal of "3D printing with Moon/Mars soil." Connection to tx07-isru-exploration-destinations.md (construction ISRU pathway) and lunar-surface-construction.md (complements MMPACT/Mason hardware level with fundamental feedstock research).

Theme 8: Mycotecture — NIAC Phase III

Mycotecture off Planet: En Route to the Moon and Mars ([158470])
NIAC Phase III. PI: Lynn J. Rothschild (NASA ARC). TRL 3→6. 2024-10 to 2026-10. 3,914 views.

Growing fungal mycelial (myco) biocomposites for space habitats, furniture, and structures. Vision: grow habitat from local organics rather than launch 29,000 kg of habitat to Mars.

Phase III roadmap (from poster, file ID 387766): 1. Earth: Fungal strain selection, radiation testing, material property characterization 2. Starlab (LEO): Test mycotecture paneling on commercial space station 3. Moon (CLPS): Lunar surface habitat prototype via Commercial Lunar Payload Services 4. Mars: Full habitat deployment (ultimate goal)

Key Phase II results: - Grew a mycelium dome atop a 4×4 m inflatable model - Developed high-throughput fungal material production method - Sand/regolith simulant composites tested - Melanin-producing strains incorporated for radiation protection - UV causes hyphal damage (challenge) - Tunable mechanical properties via production parameter adjustment

Team: Multi-disciplinary — NASA ARC (PI), architects (redhouse studios, Newcastle, Northumbria), engineers (BMSIS, Stanford, McMaster), Moonprint Solutions (inflatables), Melatech (melanin/radiation), Blue Marble Space Institute.

Assessment: Most speculative of the TX12 projects but backed by NIAC Phase III funding — meaning it survived two rounds of peer review. The specific challenge of UV hyphal damage + the logistics of delivering living fungal cultures to the Moon/Mars remain unresolved. Confidence: speculative for flight application, suggestive for material properties.

Key Findings

  1. TX12 TRL ceiling is 6. No active manufacturing/materials project has reached TRL 7+. The entire portfolio is in research and early development.

  2. ISM cluster is newly activated (2025). Five GCD projects started 2025, all under Werkheiser/Thornblom. This represents a coherent program push following the Made in Space/Redwire era.

  3. SEADS is the most technically ambitious FO project in TX12. In-space semiconductor manufacturing with Intel/Fujifilm/TEL partners — but parabolic flight results mixed; ISS demo not yet confirmed.

  4. Joining Demos TRL 4→8 ambition needs scrutiny. Same PM team as stalled OSAM-1. No technical specifics in TechPort description.

  5. Dust mitigation is a genuine STRG investment thesis (4+ parallel approaches). No dominant solution has emerged.

  6. CMU IMQCAM (5,348 views) = the foundational research that must succeed for any ISM hardware certification path.

Open Threads

  1. SEADS closeout (April 30, 2026): What TRL did EHD semiconductor printing reach? Did it get to ISS?
  2. AAMIDRSS: Long horizon (2028). What specific defect types can the sensor detect? Check for documents.
  3. Joining Demos TRL check (Oct 2026): Will Lockheed Martin achieve TRL 8? What joining methods?
  4. Mycotecture Phase III closeout (Oct 2026): Starlab paneling delivered? CLPS proposal accepted?
  5. Dust mitigation winner: Among the 4+ STRG coating approaches, which will progress to FO testing?
  6. C-Tower ([158752]): Ceres Robotics, mobile solar mast — who is funding Phase II if SBIR Phase II ends July 2026?
  7. ISM-ASTRO study results ([184656]): What does NASA decide about future ISM investments? Ends Sept 2026.
