Hubble re-enters in 2037, and is useless because of orbital mechanics a few years before that.
I think it's unlikely the current reaction wheel system lasts to that ~2032 timeframe, let alone significantly beyond.
Of 6 wheels, 2 are working well, 1 is dodgy, and 3 have failed. 3 are required to keep orientation.
