Was the Hubble telescope discontinued

Answer 1

Not yet. The Hubble Space Telescope is still in space, still operational. In fact, it received a substantial upgrade just last spring, with new gyroscopes, new sensors and a new communications array.

But the main telescope cannot be upgraded without being entirely rebuilt, which cannot be done in space. The original plan was that the Hubble Space Telescope would be captured in orbit by the Space Shuttle, returned to Earth, and rebuilt. Later, it would be re-launched. But because the Space Shuttle fleet itself is scheduled to be retired in the next few years, this plan has been abandoned.

The HST is tentatively scheduled to be de-orbited and crashed into the ocean in about 7 more years. With luck, there will be an even more powerful space telescope to replace it, but this is not yet firmly scheduled.
