“The decision to end direct federal support for the ISS in 2025 does not imply that the platform itself will be deorbited at that time — it is possible that industry could continue to operate certain elements or capabilities of the ISS as part of a future commercial platform . . . NASA will expand international and commercial partnerships over the next seven years in order to ensure continued human access to and presence in low Earth orbit.”
The budget also proposes that NASA increase reliance on commercially-operated satellites. The budget would reduce funding for “NASA’s current Government owned and operated fleet of communications satellites and associated ground stations” and cancel, “pending an independent review, an overbudget project to upgrade the current” fleet.
The budget also proposes to cut funding for NASA’s Earth Sciences research program by approximately 6% and its Astrophysics program by 12%. Five Earth Science missions—PACE, OCO-3, RBI, DSCOVR Earthviewing instruments, and CLARREO Pathfinder—would be terminated along with and one Astrophysics project—the Wide-Field Infrared Survey Telescope (WFIRST).
