The Biden Administration proposed $27.2 billion for NASA's 2024 fiscal year. If approved by Congress, this would represent a 7.1% increase over 2023 levels. The budget would grow funding for NASA's Artemis lunar exploration program, Mars Sample Return, Earth Science, and technology research and development.

Highlights include:

  • Increase Mars Sample Return funding to $949M in 2024, with the following warning "costs are expected to increase beyond what is shown in the outyear profile in this budget. To address this budget challenge, NASA will have to either reduce funding for other activities within the Science Program or descope elements of the Mars Sample Return mission."
  • An indefinite delay of the VERITAS Venus mission "due to Jet Propulsion Laboratory (JPL) workforce issues raised in the Psyche Independent Review Board findings. NASA will continue to support the VERITAS science team."
  • Proposes $210 million for NEO Surveyor "to support a June 2028 launch readiness date."
  • $30 million to increase contributions to the European Space Agency's Rosalind Franklin rover "previously a joint Europe/Russia mission, which will search Mars for indications of ancient life"
  • Increase funding for Artemis' Human Landing System program by 27% to support "additional work with SpaceX to upgrade the version of Starship used for the Artemis III mission [and] invite other U.S. companies to provide new lander development and demonstration missions from lunar orbit to the surface of the Moon with an initial demonstration on Artemis V."

Analysis: NASA's 2024 budget is a solid foundation facing political headwinds

The requested $27.2 billion would keep all major human and robotic initiatives going forward, though most of it would be offset by inflation.
