NASA wants its future space telescopes designed to be serviceable, like Hubble
In a briefing at a recent science conference, a NASA official made it clear that it wants its proposed Habitable Worlds Observatory (HWO) — presently undergoing its initial design studies for launch in the 2040s — be designed in a way that it can be maintained, repaired, and upgraded, much like the Hubble Space Telescope.
NASA is planning for HWO to be serviceable, which means that they will need to figure out a way to work on, repair, and maintain the observatory while it operates roughly a million miles (1.5 million kilometers) away. “HWO will have to be serviceable to some extent,” NASA’s astrophysics division director Shawn Domagal-Goldman told Space.com during a session at the American Astronomical Society’s (AAS) 248th meeting in Pasadena, California.
This design decision not only makes sense, NASA should have made it common practice a decade ago. The ability for robots to do this work is becoming increasingly robust, and in the next decade will become commonplace. For NASA to have launched anything in the past decade without this in mind was shameful.
