NASA | Hubble Memorable Moments: Powering Down

The video recounts a critical mission to repair the Hubble Space Telescope's power control unit. Engineers developed a procedure to safely power down the telescope, a task never done before. During the mission, a suit leak posed a significant challenge, but the team successfully managed the situation. The repair was completed, and the telescope was reactivated, ensuring its continued contribution to science. The mission highlighted the expertise and dedication of the team involved.

What was the critical issue discovered in the Hubble Space Telescope that required a complete power down?

• A problem with the telescope's lens

• A malfunction in the communication system

• A small fault in the power control unit

• A fault in the temperature control system

What was the name of the command procedure developed to power down the Hubble Space Telescope?

• Super Proc

• Telescope Off Command

• Hubble Shutdown Sequence

• Power Down Protocol

During the preparation for the power-down, what unexpected issue did the team encounter?

• A communication failure

• A spacesuit leak
