The US President FY27 Budget proposes budget cancellations to 10 Planetary science Division (PSD) projects including Venus missions such as DAVINCI, Veritas, VenSAR (Envision Contribution) and budget cancellations of up to 53 science missions.
FY 2027 President's budget request proposes a 23% cut to NASA ($18.8 billion total), including a 47% reduction to the Science Mission Directorate, which could terminate over 40–53 science missions.
The budget proposes a 26% cut to the Planetary Science Division, from the $2.541B appropriated by Congress in FY26 to a proposed $1.876B in FY27.This includes a significant reduction in the Planetary Science Research & Analysis budget. Astrophysics Research would see $297.8M to $108M from FY24 to FY27 and Heliophysics Research FY24 from $247.4M to $118.1M.
The DAVINCI with $500M max budget cap is a primary candidate for FY27 Budget cancellation would also reduce the planetary science budget by nearly a third.The ESA EnVision mission, planned for a 2032/2033 launch, relies on a NASA-provided radar instrument (VenSar 150kg with S-band 5.47m x 0.60m phased array antenna which would have been provided by JPL).The total ESA contract for Thales & partners to build the EnVision probe is €367 million $500M Cap.
With several astrophysics mission telesecopes scheduled to be canceled, Heliophysics missions such as Solar and Heliospheric Observatory (SOHO) and PSD The Mars Sample Return (MSR).
Other Major impacted projects include the Chandra X-ray Observatory and Mars Sample Return and also Office of STEM Engagement and roughly $1.1 billion from the International Space Station.
Proposed NASA cuts would mean a 47% loss to the planetary science budget from 2026 Request.
