![]() Ground-based telescopes saw a pronounced drop in costs after 1980, and the researchers say the same thing can happen with space telescopes. They can never be cheaper than ground-based telescopes, but ground-based telescopes simply can't perform the way space telescopes can. There's also no doubting their expense and their drain on NASA's budget. They deliver results impossible to get in any other way. There's no doubting the scientific rationale for large space telescopes. It is available on the arXiv preprint server. They presented their paper at the SPIE Optics + Photonics 2023 conference in August. They've written a paper presenting their thoughts titled "Approaches to lowering the cost of large space telescopes." The lead author is Ewan Douglas, an Assistant Professor of Astronomy at the University of Arizona, Steward Observatory. However, a team of researchers thinks there are ways to bring the cost of space telescopes down. These space telescopes will likely be extremely expensive. NASA is already planning and developing the Nancy Grace Roman Space Telescope (formerly WFIRST) and the Habitable Worlds Observatory (formerly LUVOIR) for launch in 2027 and the late 2030s, respectively. The JWST is barely a year into its mission and we're already anticipating the next space telescopes. Can we make space telescopes less expensive?
