Cryogenic Fluid Management (CFM) Portfolio¶
Created: 2026-04-06 (session 43)
Summary¶
The CFM portfolio is NASA TDM's major strategic investment in cryogenic fluid management — the enabling technology for long-duration space propulsion (Artemis upper stages, lunar propellant depots, Mars missions). Managed through an MSFC-led "portfolio project" structure, it funded ~12 sub-projects from 2021 onward. The portfolio project [116759] formally closed September 2024, but 3 sub-projects remain Active as of April 2026 and are completing their flight demonstrations.
Key finding: 2 of the sub-projects succeeded: SpaceX CPM&T (TRL 5 target, achieved, >3MT LOX transfer on Starship) and RFMG (TRL 7, Blue Ghost Feb 2025). The other 3 are still Active — all stuck at TRL 4 vs. targets of 7.
Portfolio Structure¶
The CFM Portfolio Project [116759] (MSFC-led, Completed Sep 2024) served as the administrative umbrella. Individual sub-projects were linked via "Advanced_From" outcomes. The portfolio itself did not conduct technology — it coordinated and documented the cluster.
Sub-project PM team (Dankanich/Peugeot/Kenny) appears in all sub-project records — the same PM team that managed the Made in Space/OSAM programs. Dankanich is STMD TDM Program Director.

The Two Successes: RFMG and SpaceX CPM&T¶
SpaceX On-Orbit Large-Scale Cryogenic Propellant Management and Transfer Demo [116764]¶
SpaceX (lead, Hawthorne CA) + GRC + MSFC | TRL 4→5 (target 5, achieved) | Nov 2020 – Dec 2024 | 2,715 views
What was demonstrated: Transfer of >3 metric tons of liquid oxygen between two tanks on a Starship in orbit. This is the on-orbit propellant transfer demonstration that was covered widely in 2024 — SpaceX used Starship's own propellant system to execute an internal LOX transfer between the header and main tanks.
TRL hit its target (5). Unlike CDM/LOXSAT 1/LEAPFROG whose targets are 7, this project had a conservative TRL 5 target — which it achieved. This reflects a realistic scoping for large-scale commercial vehicle demos where TRL advancement is bounded by the development stage of the vehicle itself.
Destination tagged: Mars + Moon and Cislunar — consistent with Starship's architecture role in NASA's sustainable Artemis/lunar depot plans.
PM: Christopher T Payne. Same program managers (Dankanich/Peugeot/Kenny) as the rest of TDM.
Significance: This is the largest cryogenic propellant transfer demonstration in spaceflight history. 3+ metric tons is orders of magnitude larger than any prior CFM demo. However, it's internal (same vehicle, same propellant type) — not a cross-vehicle transfer between depot and customer, which remains undemonstrated.

The Flight-Validated Success: RFMG [105674]¶
Radio Frequency Mass Gauging (GSFC-led, TRL 5→7). Flew on Intuitive Machines IM-1 Blue Ghost, which reached the lunar surface February 26, 2025. RFMG measured propellant mass in the tank by analyzing the resonant frequencies of an RF cavity — the approach is independent of orientation and works in microgravity. The test was successful throughout the mission.
This is TechPort's clearest CFM flight validation to date. The NextGen RFMG [158537] (TDM, TRL 4→5, 2023-2028) builds directly on this heritage with an SDR-based implementation.
TRL 5→7 in one flight test: consistent with FO program model (relevant environment = TRL 7). RFMG is the CFM portfolio's only completed flight demonstration.
The Three Still-Active Sub-Projects¶
CDM — Cryogenic Demonstration Mission [116762]¶
Lockheed Martin (lead) + ABL Space Systems + GRC + MSFC + K T Engineering | TRL 4→7 | May 2021 – Apr 30, 2026 | 3,014 views
Most ambitious sub-project: 17 critical CFM technologies in a single integrated LH2 flight demonstration. Technologies include LH2 transfer, long-duration storage, and pressure control. This is the capstone the entire portfolio was designed to build toward.
TRL stall: Began at TRL 4 in 2021. Still at TRL 4 in April 2026 — five years with no TRL advance, despite a target of 7. As of April 2026, CDM ends April 30.
ABL Space Systems is listed as a partner organization. ABL Space's RS1 rocket failed its first and only launch attempt in January 2023; ABL subsequently shut down its commercial launch business. CDM never recorded a TRL advance — TRL 4 at project start, TRL 4 at the final month before April 30, 2026 closeout. Zero TRL gain after 5 years. This is the worst outcome in the CFM portfolio — the capstone project, intended to demonstrate 17 critical LH2 technologies in a single integrated flight demo, appears never to have flown.
RFMG NextGen connection: [158537] (2023-2028) does not depend on CDM's success — it's SDR-based and extends the lunar gauging capability. CDM's LH2 transfer and storage results (if any) would inform future TDM investments.
Confidence: Confirmed Active as of Feb 13, 2026. Outcome record not yet filed. Check after April 30, 2026 for final status update. The ABL RS1 failure in January 2023 is the most plausible explanation for the zero TRL gain — speculative, not confirmed in TechPort records.
LOXSAT 1 [116757]¶
Eta Space (lead, Merritt Island FL) + Rocket Lab Photon | TRL 4→7 | Apr 2021 – Apr 2027 | 3,247 views
Small-scale flight demonstration of a complete LOX (liquid oxygen) fluid management system. Scope: 10 different CFM technologies on a 9-month technology demonstration as the primary payload on a Rocket Lab Photon satellite in LEO.
Assessment: Most likely to fly of the three. Rocket Lab Electron is an operational commercial launch vehicle with regular cadence; Photon satellites have flown to high-energy orbits (CAPSTONE used a Photon). Eta Space is a dedicated cryogenics startup. Ends April 2027 — a year from now. The LOX fluid management challenge is less demanding than LH2 (higher temperature, lower vapor pressure).
TRL stall: At 4 vs. target 7. Has not yet flown or recorded TRL progress. States: AL, CA, CO, FL, MN, OH — multi-org consortium.
LEAPFROG (Long Endurance Advanced Prototype Flight Demonstration) [116758]¶
United Launch Alliance (lead, Denver CO) | TRL 4→7 | Sep 2021 – Sep 2026 | 2,730 views
Most operationally integrated: ULA LEAP experiment is embedded in the Centaur V upper stage itself — the LH2 main propulsion stage of the Vulcan Centaur rocket. The demonstration involves: - LH2 propellant transfer from Centaur V main tank to an auxiliary (LEAP) LH2 tank in microgravity - Tank pressure control - LEAP LH2 thruster operation using Centaur V propellants - Line chilldown and No-Vent-Fill demonstration
This is not a dedicated demonstration vehicle — it is embedded in an operational launch system. Every Vulcan Centaur mission that uses a Centaur V upper stage is a potential LEAPFROG test opportunity. Vulcan Centaur completed its first flight in January 2024 (VC1, with Astrobotic Peregrine CLPS payload). Subsequent Vulcan missions would carry the LEAP experiment as a secondary objective.
TRL stall: At 4 vs. target 7. Ends September 2026 — five months from now. TX mismatch: human classified TX14 (thermal/storage), ML predicts TX01 (propellant systems).
Key question (TechPort can't answer): Has LEAPFROG already flown on Vulcan Centaur? The TRL remaining at 4 and the Active status suggest either it hasn't flown yet, or it has flown but TechPort hasn't been updated.
Pattern Analysis¶
Two successful demos, three still-Active: - SpaceX CPM&T [116764] (>3 MT LOX internal transfer, TRL 5) and RFMG [105674] (gauging, TRL 7) both succeeded. - CDM, LOXSAT 1, and LEAPFROG (propellant management and cross-vehicle transfer, complex integration) are all stuck at TRL 4 vs targets of 7.
Pattern: Conservative TRL targets succeed; ambitious ones (TRL 7 = flight validation in relevant environment) lag. SpaceX's Starship demo was scoped to TRL 5 (tech demonstration) and used an existing vehicle's own internal transfer system — not a cross-vehicle depot scenario. RFMG is a sensor, not an active management system. The hard problem — external cross-vehicle LOX/LH2 transfer in orbit — remains undemonstrated.
CFM as Artemis dependency: NASA's sustainable Artemis architecture requires in-space propellant depots and cryogenic transfer. If none of the three active flight demos succeed before 2027, the technology gap in LH2 active management grows. RFMG's success addresses gauging. Storage and transfer remain undemonstrated at TRL 7.
Portfolio umbrella closure (Sep 2024): The portfolio project closed, but the three sub-projects continued under TDM. This may represent budget and schedule restructuring after the portfolio's formal multi-center coordination ended.
