The Chandra X-ray Observatory, one of NASA’s vaunted Great Observatories that has transformed our understanding of the high-energy universe, now teeters on the brink of a funding abyss. In a proposed retrenchment, NASA’s fiscal year 2025 budget outlines severe cuts to Chandra’s operating budget, eliciting a chorus of disapproval from the astronomical community. Astronomers fear such cuts could spell the premature end of Chandra, leaving a void in X-ray astronomy that might not be filled for years.
Launched in 1999, Chandra has been a cornerstone of astrophysical research, allowing scientists to probe phenomena like supermassive black holes and galaxy clusters. It has complemented other space telescopes, including James Webb Space Telescope launched in 2021, by confirming the existence of entities like young galaxies. These cooperative ventures between telescopes underscore the value of a diverse suite of observational instruments.
NASA justifies these budget cuts with a narrative of degradation and rising operation costs, stating, “The Chandra spacecraft’s thermal management has been degrading over its mission lifetime, requiring active management to keep temperatures within acceptable ranges for spacecraft operations.” and “This makes scheduling and the post-processing of data more complex, increasing mission management costs beyond what NASA can currently afford.” Consequently, the agency has earmarked the once $68.3 million budget for a gradual wind down, slashing it by 40% to $41.1 million in 2025 and charting a decline to a scant $5.2 million by 2029.
However, astronomers argue that the degradation of Chandra has been manageable, countering NASA’s rationale. Patrick Slane, director of the Chandra X-ray Center, contends that despite challenges like increasing temperatures, the mission has effectively adapted with no significant loss in efficiency or complexity in data processing. Thus, the projected budget would not merely reduce operations but rather lead to Chandra’s decommissioning.
NASA officials stress the need to “balance the portfolio” amidst a challenging budget environment, according to Mark Clampin, astrophysics division director at NASA Headquarters. However, this approach has not sat well with many in the community. At a NASA Astrophysics Advisory Committee meeting, Nicola Fox, NASA associate administrator for science, acknowledged the search for more efficient ways to operate missions.
