List of proposed space telescopes

List of proposed space telescopes

Add article description


This list contains proposals for space telescopes, space-based (situated in space) astronomical observatories. It is a list of past and present space observatory plans, concepts, and proposals. For observatories in orbit, see list of space telescopes. Unlike that list, this one includes concepts and proposals that are unlikely ever to be launched, as they may have been cancelled or were only proposals.

Additional examples and non-space telescopes

For launch in the 2030s, NASA is evaluating four possible designs: the Origins Space Telescope, Lynx X-ray Observatory, Habitable Exoplanets Observatory (HabEx), and Large UV Optical Infrared Surveyor (LUVOIR).[28]

Balloon-borne telescopes have been in use since the 1950s. A 20–30 meter balloon telescope has been suggested.[29] The balloon would be transparent on one side, and have a circular reflecting mirror on the other side.[29] There are two main designs using this principle.[29]

  • Large Balloon Reflector (LBR) (sub-orbital version)
  • Space-based Large Balloon Reflector (LBR)
    • TeraHertz Space Telescope (TST)[30]

Additional examples

8 meter segmented LUVOIR-B (formerly ATLAST) telescope
ATLAST produced several versions for the LUVOIR telescope
