NASA is asking commercial space companies how they would extend the life of the Hubble Space Telescope, which is expected to reenter the atmosphere by 2034.
That date is the clock. Hubble's orbit is slowly decaying, and left alone it is expected to come down by 2034. The telescope has also developed several malfunctions on board. NASA's request is for proposals, so what exists today is an open call to industry for ideas, not a chosen plan.
The two problems are not the same, and that shapes what a good answer looks like. Reentry is a question of altitude. The malfunctions are a question of aging hardware. A company that could only push Hubble into a higher orbit would buy time, but it would not fix what is already failing aboard. Extending the telescope's life in a meaningful way likely means addressing both, or accepting that Hubble keeps working in a diminished state.
The open question is whether any proposal can handle the orbit and the failing hardware together, or whether NASA ends up choosing which problem to solve first.
