I’m writing to you about budget cuts to NASA and the Chandra X-ray observatory are very concerning to me. Please restore full funding (approximately $70M/yr) to NASA’s Chandra X-ray Observatory in any FY25 legislation. Chandra, the most powerful X-ray telescope in history, is the vanguard of U.S. Leadership in High Energy Astrophysics, a Nobel-prize winning field that began in the US. Chandra is healthy, efficient, and returning its best-of-mission science. Its greatest discoveries lie ahead. Chandra is a keystone of multi-wavelength observations, providing enormous synergy with the James Webb Space Telescope and essentially all cutting-edge ground-and space-based telescopes for the next 5-10 years, vastly increasing our return-on-investment in these major facilities. It is critical that full funding to Chandra is restored before it’s too late. Without Congress, the proposed FY25 funding for Chandra would mandate devastating cuts to Mission Staffing by the fall of 2024, potentially leading to loss of the mission. Premature loss of Chandra will result in a death spiral for X-ray astronomy in the United States, resulting evaporation of a talented national workforce, and ceding US Leadership in the most important cosmic discoveries of the coming decade. The restoration of Chandra cannot be an unfunded mandate to NASA. Please take action to modestly increase the NASA Astrophysics Budget to ensure U.S. Leadership in making the greatest cosmic discoveries of the century. Thank you for everything you and your staff do to support your constituents and our incredible country.
