Mars Campaign Office (MCO)

Last updated: session 50, 2026-04-06

Summary

The Mars Campaign Office (MCO) is the NASA program managing technology development for long-duration human spaceflight — explicitly dual-destination: every active project is tagged both Mars and Moon. MCO is the umbrella for human life support, crew health, fire safety, radiation protection, food systems, and Earth-independent operations. It is not a Mars-only program in practice; it builds the human survival infrastructure required to keep humans alive for 1,000+ day missions regardless of destination.

122 total projects | 49 Active (40.2%) | 67 Completed (54.9%) | 6 Canceled (4.9%)

The 40.2% active rate is among the highest of any major NASA program — only MCO (new program, high growth rate) and GCD (54 active) approach this. For a 122-project program this is a sign of recent significant investment.

Portfolio Structure

By Technology Area (all 122 projects)

TX Area Count % Description
TX06 66 54.1% Human Health, Life Support, Habitation
TX07 22 18.0% Exploration Destination Systems (logistics, ISRU, habitation)
TX10 6 4.9% Autonomous Systems
TX12 5 4.1% Materials, Structures
TX01 4 3.3% Propulsion
TX13 4 3.3% Ground/Launch Infrastructure
TX09 4 3.3% Entry, Descent, Landing
TX05 3 2.5% Communications/Navigation
TX14 2 1.6% Thermal/Cryogenic
TX02 2 1.6% Computing/Avionics
TX08 2 1.6% Sensors/Instruments

Active portfolio (49 projects) is dramatically more concentrated: TX06 = 83.7% (41/49). When only active projects are considered, MCO is essentially a pure human health and life support program.

By Lead Organization (active projects)

Org Count %
Johnson Space Center 28 57.1%
Marshall Space Flight Center 6 12.2%
Glenn Research Center 5 10.2%
Ames Research Center 4 8.2%
Kennedy Space Center 2 4.1%
International Space Station 1 2.0%
IRPI, LLC 1 2.0%
Langley Research Center 1 2.0%
Goddard Space Flight Center 1 2.0%

JSC-dominant (57.1%) — consistent with JSC's mandate as the human spaceflight center. The 1 industry lead (IRPI, LLC on Emergency Breathing Apparatus) makes MCO essentially a NASA-center-only program. No academic grants, no SBIR — MCO funds center work.

TRL Distribution (all 122 projects)

TRL Count %
4 32 26.2%
5 27 22.1%
3 17 13.9%
6 16 13.1%
7 15 12.3%
2 9 7.4%
9 3 2.5%
8 2 1.6%
(none) 1 0.8%

TRL 4-5 dominant (48.3%). Only 1 null — MCO has excellent TRL data quality (99.2% fill rate). TRL 7+ = 20 projects (16.4%) — significant high-TRL output from a mid-TRL program.

Temporal Patterns

Three equal cohorts, each 17 projects: - 2011 cohort: cFS, OPALS laser comms, BEAM, disruption tolerant networking, Ka-Band debris tracking, Lunar-g Combustion, Autonomous Systems - 2014 cohort: AMPS power systems, CO2 removal, O2 gen, water processing, UWMS, logistics reduction (RFID + transfer bag), ShadowCam, MOXIE - 2024 cohort: EIO domain (4 projects, 2024-2030+), CEPS radiation, LOONS neutron spectrometer, HZETRN physics, food refrigeration, bioregenerative LSS, FROSTE cryogenic samples

2020-2022 sustained ramp-up: EES exercise (2020), crew health analogs, fire safety instruments. This 30-project cohort represents the Artemis era acceleration.

Pattern: The 2011 cohort projects are general human spaceflight infrastructure (cFS, laser comms, BEAM) that later got reclassified under MCO. The 2014 cohort built the ECLSS core. The 2020+ cohort is maturing those systems to exploration readiness, and 2024 added the EIO domain.

Destinations

Every active MCO project is tagged Mars (100%), and 89.8% also tagged Moon and Cislunar. This is MCO's defining programmatic statement: the technologies are dual-use for both destinations. Historically (all 122 projects): Moon=75.4%, Mars=73%. Projects have multiple destination tags.

Active Portfolio: Technology Clusters

Cluster 1: ECLSS Core (~15 projects, MSFC + JSC lead)

The fundamental life support systems for exploration missions, all building from ISS heritage toward exploration-class capability:

Project ID Lead TRL Target End
CO2 Removal (93177) LSS MSFC 5 6 2030
O2 Gen and Recovery (93167) LSS JSC 4 6 2030
Wastewater Processing (93182) LSS JSC 4 6 2029
Oxygen Generation Assembly (157887) OGA ISS 6 9 2029
Universal Waste Management System (93128) UWMS JSC 7 8 2029
Urine Processor Assembly Upgrades (157885) UPA JSC 7 9 2028
Water Processor Assembly Upgrades (157886) WPA JSC 6 9 2029
AMCHX Condensing HX (157884) CHX JSC 5 9 2030
Exploration Sabatier (184079) ExS MSFC 4 7 2028

UWMS (5,250 views) and AMCHX (5,164 views) are the highest-viewed active MCO projects. These are the projects the community is tracking. UWMS is operational on ISS; AMCHX (157884) is a 3D-printed condensing heat exchanger targeting TRL 9 — one of the highest TRL targets in the active portfolio for a non-ISS-heritage device.

OGA TRL 9 target (157887) is credible: OGA is already deployed on ISS and has been producing oxygen for 13+ years. This project develops a compact exploration version. Target TRL 9 = flight-qualified exploration hardware, not speculative.

Cluster 2: Fire Safety (5 projects, GRC lead)

GRC runs MCO's fire safety portfolio, following the Saffire (13543) series (TRL 3→9, 2011-2025). Saffire burned materials inside a Cygnus cargo vehicle post-undocking — the only realistic large-scale spacecraft fire test possible. Series is now complete (TRL 9).

Current fire safety work: | Project | ID | Lead | TRL | End | |---------|-----|------|-----|-----| | Lunar-g Combustion (157846) | | GRC | 7 | Completed 2025 | | Partial-g Fire Detection (157850) | | GRC | 3 | 2029 | | Fire Scenario Modeling (157847) | | GRC | 5 | 2030 | | Li-ion Battery Tests (157848) | | GRC | 4 | 2027 | | Acid Gas Detection (157849) | | GRC | 5 | 2027 | | Emergency Breathing Apparatus (157851) | | IRPI | 5 | 2027 |

The Li-ion battery fire (157848) is identified as the worst-case spacecraft fire scenario for Orion. This project characterizes Li-ion thermal runaway behavior in elevated O₂/reduced pressure spacecraft atmospheres. Critical for HLS and Gateway cabin safety design.

Cluster 3: Human Health / Countermeasures (~10 projects, JSC lead)

Project ID TRL Range End
EES Development (157163) 4 1→9 2029
EES Physiology (157164) 3 1→7 2030
Sensorimotor Countermeasures (157166) 5 2→9 2030
MAVRIIC decision support (157165) 3 1→6 2026
Crew Health Analog CHAPEA (157177) 6 6→7 2029
Crew State & Risk Model (157626) 4 2→7 2030
Food Water Reduction (157181) 2 2→4 2033

Multiple TRL 9 targets (EES Dev, Sensorimotor) are ISS deployment targets — not speculative. These systems need to fly on ISS to demonstrate crew effectiveness. CHAPEA (157177) is the Mars surface analog habitat at JSC (crew isolation studies) — currently Active with TRL 6 and Transitioned_To outcome.

Cluster 4: Medical (~5 projects, JSC lead)

Project ID TRL End
Mini OCT (157621) 6 2029
Multi-Functional Medical Device (157729) 7 2026
IV Fluid Generation (96991) 6 2027
Chiron Health Portal (145030) 4 2027
Mag-EC ELISA (182471) 2 2027

Mini OCT (157621) — Spaceflight Associated Neuro-ocular Syndrome (SANS) diagnostic device. SANS (optic disc edema, visual impairment) is one of the top unresolved health risks for long-duration spaceflight. Mini OCT provides onboard retinal imaging to diagnose and monitor SANS without Earth support. TRL 5→9 target — needs ISS deployment.

MFMD (157729) — miniature multi-function medical device, TRL 6→8, ends Sept 2026. Consolidates 7+ separate medical functions (ultrasound, ECG, vitals) into one compact device for crews >6 months from Earth. TRL 7 now.

Cluster 5: Radiation Protection (4 projects)

Project ID Lead TRL End
CEPS radiation spectrometer (182428) JSC 4 2031
LOONS neutron spectrometer (182437) GSFC 4 2031
HZETRN physics (182431) LaRC 3 2030
Solar Particle Warning (ISEP) (182433) JSC 6 2030

All 4 are from the 2024 cohort — new radiation protection cluster. CEPS and LOONS are instruments; HZETRN is a radiation transport code. ISEP (182433) (Solar Energetic Particle Warning) is at TRL 6 — near operational. The MCO "RadWorks" umbrella has been running since 2018.

Cluster 6: Earth Independent Operations (EIO, 4 projects, 2024)

All 4 EIO projects started Oct 2024, running through 2030-2036. See topics/mco-eio-earth-independent-ops.md for full analysis. Summary: - Vehicle Systems (157866) — HPSC + ECLSS testbeds, TRL 4, 2031 - Anomaly Response (157864) — ML fault detection, TRL 3, 4,068 views - Mission Management (157867) — MSFC, TRL 2, 2036 horizon (longest in MCO) - Crew Interaction (157865) — ARC, TRL 3, human-computer interaction for Mars

Cluster 7: Food and Bioregenerative Systems (KSC + JSC)

Project ID Lead TRL End
Ohalo III crop production (97036) KSC 6 2029
Bioregenerative Life Support (157839) KSC 5 2029
Mars Food Refrigeration (182790) JSC 5 2031
Food Water Reduction (157181) JSC 2 2033

Ohalo III (4,587 views) — already producing lettuce and food crops in ISS-representative closed environments. TRL 6 → 9 target. See topics/mco-human-health-countermeasures.md.

Bioregenerative Life Support [157839] — the integration hub for biological waste recycling. Not a single technology but the coordination effort connecting multiple bioreactor streams (USF fecal/wastewater bioreactors, Texas Tech/JSC urine bioreactor, KSC APMBR+AnMBR) into a closed-loop system. TRL 5 currently, target TRL 7 by 2029. On the critical path to Artemis X (2035) permanent lunar habitat. Full analysis: topics/bliss.md.

High-TRL Completed Projects

The historical portfolio includes some significant technology achievements:

Project ID TRL Period What
Spacecraft Fire Safety Demo (Saffire) 13543 3→9 2011-2025 Saffire I-VI series: large-scale spacecraft fires inside Cygnus post-undocking
Core Flight Software 11771 9→9 2012-2014 cFS — the NASA open-source flight software standard, now used across most NASA missions
OPALS (Optical Payload for Lasercomm Science) 13541 7→9 2009-2014 JPL laser comms demo on ISS — first optical link from space
BEAM (Bigelow Expandable Module) 11692 7→9 2013-2020 Bigelow expandable habitat attached to ISS, still in use
Cardiovascular Countermeasures 157168 4→9 2020-2024 ISS-deployed cardiovascular exercise countermeasures
Polaris ASTRA 116432 5→9 2021-2024 SSC, autonomous satellite technology for space robotics
Polaris DPAC 116433 2→9 2021-2023 MSFC, mission planning/control autonomous software (TRL 2→9 in 2.5 years — suspicious)
Near Earth Asteroid Scout 14656 7→9 2014-2023 Solar sail CubeSat, flew on SLS-1, Nov 2022 (comms failure; TRL 9 claim questionable)
Autonomous Systems and Operations 32946 5→8 2014-2024 ARC, activity/resource planning, TRL 5→8 in 10yr
Lunar-g Combustion Investigation 157846 2→7 2022-2025 GRC, combustion in partial gravity — feeds lunar fire detection design

Polaris DPAC (116433): Verified session 50. TRL current = 7 (not 9 — the trlEnd=9 was misread in session 49 via trl_min filter). Outcome: Transitioned_To ISS (Oct 2024) + Closed_Out (Jun 2025). The software was deployed to ISS as a mission planning/control tool. TRL 7 = demonstrated in relevant environment (ISS deployment). TRL 9 was the target but not achieved — the Transitioned_To record marks adoption into operations, but the project closed at TRL 7. Data quality flag resolved: TRL 2→7 in 2.5 years, still fast but credible for flight software deployment.

NEA Scout (14656): Verified session 50. TRL current = 7 (began at 7, target was 9). Outcome: Closed_Out 2023-09-01. Has a closeout report. TRL 7 is appropriate — the spacecraft hardware was verified in its launch environment, but comms failed post-deployment so TRL 9 (successful operation in final environment) was never achieved. Data quality flag resolved: no error in TechPort, TRL 7 is correctly recorded.

Outcome Tracking

  • Transitioned_To: 12 (highest fraction of any MCO outcome type)
  • Infused_To: 0
  • Closed_Out: unknown (not queried)

Key Transitioned_To outcomes: - MOXIE (33080) — Mars Oxygen ISRU experiment, JPL. TRL 5. Flew on Perseverance rover (Feb 2021 landing). Produced oxygen on Mars surface (SOEC electrolysis). First in-situ resource utilization technology to operate on Mars. MCO project → actual Mars mission. - ShadowCam (96950) — ASU, TX08, TRL 6. NASA instrument on KPLO (Korean Pathfinder Lunar Orbiter), launched Aug 2022. Images permanently shadowed regions of lunar surface. - UWMS (93128) — ISS toilet, TRL 7. Operational on ISS. - REALM (93175) — RFID autonomous logistics, TRL 7. Operational RFID system for ISS cargo management. - Logistics Transfer Bag (93176) — TRL 7→8, reusable crew transfer bag, ISS deployed. - CHAPEA (157177) — crew analog habitat, TRL 6. 3 CHAPEA missions at JSC simulating Mars surface operations. - Polaris DPAC (116433) — autonomous planning, Transitioned_To noted. - RadWorks (10581) — radiation monitoring, TRL 6.

Program Character

What MCO is

MCO is the human spaceflight equivalent of GCD's surface technology portfolio — it builds the survivability stack. Where GCD makes hardware to operate on lunar/Martian surfaces, MCO makes the systems that keep humans alive and healthy during the journey and stay. The dual-destination mandate (Moon + Mars 100%) is programmatic — MCO does not fund Mars-specific technology; it funds human physiology and life support technology that applies to any long-duration mission.

JSC dominance

57.1% of active projects are JSC-led. This reflects JSC's institutional mandate as the human spaceflight center. MSFC adds propulsion/life support subsystems. GRC runs fire safety. ARC leads EIO. The distribution is function-driven, not politically distributed.

No SBIR, no academia

MCO projects are 100% NASA center work (one industry exception: IRPI for Emergency Breathing Apparatus). This distinguishes MCO from STRG (academic grants), SBIR (industry-led), and GCD (industry partnerships). MCO is building core government capability that cannot be outsourced to industry at this stage — the physics of human physiology in space is a government-funded basic capability.

The 10-year gap

The 2011-2014 cohorts and 2024 cohort are each 17 projects. The gap (2015-2019: only ~20 projects) reflects budget volatility and the transition from ISS-focused to exploration-focused programs. The 2020-2022 acceleration = Artemis program re-establishing the human spaceflight technology roadmap.

Open Threads

  1. UWMS + UPA closeout (2028-2029) — Both currently TRL 7-7, targeting 8-9. What specific technologies close the gap from ISS-proven to exploration-proven?
  2. ~~NEA Scout TRL 9 flag~~ — RESOLVED (session 50): TRL current = 7 (not 9). Target was 9, never achieved. Outcome: Closed_Out 2023-09-01. No data error — TRL 7 correctly recorded.
  3. ~~Polaris DPAC TRL 2→9 in 2.5 years~~ — RESOLVED (session 50): TRL current = 7 (not 9). Transitioned_To ISS (Oct 2024), Closed_Out (Jun 2025). TRL 7 = ISS deployment. TRL 9 was target, not achieved.
  4. MOXIE scale-up gap — PARTIALLY ADDRESSED (session 50): OxEon MOMS [158003] SBIR active through Sept 2026 is targeting 1-3 kg/hr O2 at TRL 5. This is at the lower bound of mission-relevant production. No TRL 7+ system demo is funded. See topics/mars-isru-o2.md for full analysis.
  5. EIO Mission Management (157867) — ends 2036, longest horizon in active MCO by 5 years. This 12-year program represents MCO's commitment to Mars readiness. What are the major milestones?
  6. ~~Bioregenerative Life Support~~ — RESOLVED (session 50): Full architecture mapped. See topics/bliss.md. Four-stage evolution framework, six bioreactor streams, Artemis X (2035) target, BLiSS [157839] is the integration hub.
