This activity requests $20.1M in FY2027, 15% of project MSL-01, down 42% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project MSL-01 of PE 0602025E. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.

FY2027 planned work

- Complete builds of operationally relevant magnetohydrodynamic prototype pumps and conduct operational testing. - Conduct operational analysis and assessment of scalability study, evaluate future transition paths for PUMP technology. - Perform full scale inlet testing to verify modeling and simulation tools for VLEO inlets. - Complete testing and characterization of low drag materials systems developed for low earth orbit (LEO). - Deploy low drag materials to a persistent low Earth orbit spacecraft. - Develop and validate microstructure-informed lifing models to predict the performance of additively manufactured structural components. - Demonstrate the transferability of the sensor package and lifing models across two additive manufacturing platforms and two feedstock suppliers. - Explore applying previously developed methods to predict the service life and failure modes of a challenge part. - Demonstrate novel intrinsic approaches for metal-like toughness in ceramics and manufacture bulk ceramic part of more significant thickness, while also exceeding even greater flexural strength and even greater fracture toughness.

FY2026 to FY2027 change

The FY 2027 decrease reflects a shift from space launch and system development activities to testing and demonstration.

Before the request year

FY2026: the year under way

Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

FY2026 plans — current year

- Deliver experimental payloads for in-space demonstration of polymer composite manufacturing and radio frequency antenna structure assembly. - Launch and conduct material manufacturing and assembly technology demonstrations in low earth orbit. - Complete thruster testing for sustained operations in very low earth orbit (VLEO). - Test optimized design of air-collecting inlet and use experimental data for model validation. - Test low-drag materials for use in low Earth orbit to understand drag and degradation characteristics. - Test low-drag coatings applied to actual spacecraft components for preservation of functional performance to de-risk near-term inclusion on flight spacecraft. - Complete design for the prototype and scalability study for an operationally relevant magnetohydrodynamic pump. - Complete electrode material testing and concept feasibility verification to determine candidates suitable for an operationally relevant prototype magnetohydrodynamic pump. - Develop sensor packages capable of detecting micro-scale defects during metal additive manufacturing. - Develop microstructure model of additively manufactured components that include defects. - Explore and develop microstructure-based component-lifing models to predict the performance of additively manufactured structural hardware. - Develop and fabricate bulk ceramic test coupons that are of a certain minimum thickness, while also exceeding a particular flexural strength and a specific fracture toughness. - Assess ceramic microstructure stability through elevated temperature exposure. - Add additional complexity to material composition to ensure system can operate with unstable supply lines. - Plan testing and validation of material conversion capabilities for a widely varied scrap materials. - Verify and validate complex material predictions with unknown and contaminated material. - Perform burst pressure test on pressure vessels to validate material performance prediction capabilities. - Execute end-to-end design validation analysis of scrap material conversion, material property prediction, and redesign of a rocket.

Three years, and no five-year plan

An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.

This activity is 15% of project MSL-01's FY2027 request and 1.2% of PE 0602025E's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
