The future of NASA's Earth science missions is hanging in the balance. Some missions are already being asked to plan for their own end. This worrying news came from Rep. George Whitesides, who shared that both new and ongoing Earth science missions have been told to get ready for potential budget cuts starting in 2026. He stressed that this is not a final decision, but the mere possibility is a big red flag.

This news has sparked a lot of talk about what the White House might do with NASA's budget. Some reports suggest that the science budget could be cut by as much as 50%. That's a huge chunk of the current $7. 3 billion budget. Nicky Fox, NASA's associate administrator for science, was asked about these rumors. She said NASA hasn't seen the 2026 budget yet, so they haven't run any scenarios. But she did warn that a 50% cut would mean some tough decisions.

Other NASA officials are also feeling the uncertainty. Karen St. Germain, director of NASA's Earth science division, dodged questions about the budget, saying it's above her pay grade. Shawn Domagal-Goldman, acting director of NASA's astrophysics division, said they're at "peak uncertainty" right now. This includes budget worries and potential agency restructuring.

The budget uncertainty is affecting both new and old missions. For example, NASA is planning to release a call for a new Small Explorer astrophysics mission, but that depends on the 2026 budget. The same goes for NASA's response to a senior review of extended astrophysics missions, like the Hubble Space Telescope. The challenge is that they don't know if they'll have a flat budget or if it will change.

Adding to the confusion is the reported termination of $420 million in NASA contracts. The agency hasn't given details on which contracts were cut. Casey Dreier, chief of space policy at the Planetary Society, found only about $74. 5 million in terminated contracts. Charles Webb, acting director of NASA's planetary science division, said he hasn't seen details about the terminated contracts. He suggested that the decisions are being made by the NASA Shared Services Center, which handles procurement activities.
