Planetary Science at a Crossroads: Triumph, Uncertainty, and the Fight to Protect NASA's Future

The past week has brought a mix of triumph, uncertainty, and new discoveries in planetary science, especially in the United States, as the field continues to expand our understanding of the solar system and beyond. One of the most striking developments is the ongoing analysis of supernova SN 2025PHT, spotted in the galaxy N G C 1637. Remarkably, the James Webb Space Telescope, known as JWST, captured images of what appears to be the progenitor star before it exploded in July 2025. According to data from the All Sky Automated Survey for Supernovae and follow-up observations by Hubble and JWST, this marks one of the rare instances where astronomers have a clear view of a star both before and after it becomes a supernova, shedding light on the final stages of stellar evolution and the environments in which these cosmic explosions occur. Meanwhile, NASA’s ability to conduct planetary science faces mounting challenges due to a U.S. government shutdown, which has left about eighty five percent of the NASA workforce on unpaid leave, as reported by The Planetary Society. Despite the shutdown, recent advocacy efforts by scientists and space supporters have yielded partial victories. The House of Representatives has moved to maintain NASA’s overall budget at twenty five billion dollars, a significant improvement over earlier White House proposals that would have slashed science funding by almost half, with Earth Science programs bearing the brunt. This reprieve has already saved missions like OSIRIS APEX, a spacecraft repurposed to visit the asteroid Apophis in 2027, from cancellation. Yet, the future remains uncertain, with ongoing pressure to defend the science budget and prevent further program cuts. In California, the University of California, Santa Cruz, has highlighted how crucial NASA funding is for research and education. According to the university’s annual report, NASA is a top ten source of external research funding, supporting work in astronomy, planetary science, and related fields. Earlier this month, researchers nationwide participated in a Day of Action to advocate for preserving NASA’s science programs, fearing that proposed cuts could jeopardize future missions and scientific progress. On the bright side, space missions continue to push forward internationally. China’s Tianwen-2 mission is expected to launch in 2025 on a journey to a near-Earth asteroid and later to a comet, showcasing the global expansion of planetary exploration. In the U.S., a diverse slate of planned missions for 2025 includes NASA’s S P H E R E X and P U N C H, both designed to launch on SpaceX’s Falcon 9, as well as new lunar landers from private companies like Astrobotic and Intuitive Machines, and a potential crewed polar orbit mission by Fram2. However, exact launch dates for many of these remain uncertain, reflecting both the ambition and the instability of the current environment.
