Clickbait fluff article.
Hubble stopped working. NASA engineers have determined that Hubble broke it's PCU. Need to switch to the backup. If the programming instructions to switch to the backup fail, Hubble might be no more.
>So NASA engineers checked and double-checked their plans before the agency approved the switch. The team has run simulations of the switch on Hubble-imitating computers on Earth, and NASA has done two reviews of the hardware-switching procedures.
>NASA has rebooted Hubble using this type of operation in the past. In 2008, after a computer crash took the telescope offline for two weeks, engineers switched over to redundant hardware.
So it looks like they are undertaking the necessary precautions.

All testing of procedures for the switch and associated reviews have been completed, and NASA management has given approval to proceed. The switch will begin Thursday, July 15, and, if successful, it will take several days to completely return the observatory to normal science operations. > The team performed a similar switch in 2008 ...
