From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by 98.207.237.179 (talk) at 00:35, 19 May 2020 (→‎Proposed space observatories: Xuntian: updated launch year). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

This list contains proposals for space telescopes, space-based (situated in space) astronomical observatories. The list of proposed space observatories 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.

Proposed space observatories

"Active" in this list means it is still under consideration for development, not that it is in orbit

Design studies

Calisto architecture for SAFIR.[33] This shows a design concept for a deep infrared space telescope harnessing JWST technology, for the SAFIR program.

Four NASA Design studies from 2018:[34]

Additional examples and non-space telescopes

For launch in the 2030s, NASA is evaluating four possible designs: the Origins Space Telescope, Lynx X-ray Surveyor, Habitable Exoplanet Imaging Mission (HabEx), and Large UV Optical Infrared Surveyor (LUVOIR).[36]

Balloon-borne telescopes have been in use since the 1950s. A 20–30 meter balloon telescope has been suggested.[37] The balloon would be transparent on one side, and have a circular reflecting mirror on the other side.[37] There are two main designs using this principle.[37]

  • Large Balloon Reflector (LBR) (sub-orbital version)
  • Space-based Large Balloon Reflector (LBR)
    • TeraHertz Space Telescope (TST)[38]
