The next space telescope will be the Nancy Grace Roman telescope which is a wide angle telescope so not an exact replacement. https://roman.gsfc.nasa.gov/ http

The longer term goal is the Luvoir telescope but its not yet been approved and will probably require significant R&D like JWST.

- mlyle 4y agoSure. I'm not talking about the timelines of existing plans for new telescopes. I'm comparing ROI vs: - mission to reboost and service Hubble in various ways - launching a new space telescope mission
- Sharlin 4y agoIt takes about fifteen years from concept studies to launch for a Hubble-class space telescope. I guess you could make it in ten if you just chose to replicate Hubble's instruments and if NRO had another spare Keyhole stashed somewhere...
- MichaelCollins 4y agoThe NRO donated two and parts for a third to NASA in 2012. One is apparently being used for the Roman Space Telescope, which would seem to leave another and a primary mirror of a third still unused.
