Hubble Tool Time Episode 6: Servicing Mission 4

The video features NASA astronaut John Grunsfeld, astronaut trainer Christy Hansen, and EVA engineer Ed Rezak discussing the challenges and solutions involved in repairing the Hubble Space Telescope. They explain the importance of extra-vehicular activities (EVA), the design of astronaut-friendly tools, and the use of a fastener capture plate to prevent screws from floating away. The video also highlights the detailed procedures and training required for successful spacewalks, emphasizing safety and precision in a vacuum environment.

What is the primary purpose of a spacewalk?

• To explore new planets

• To perform maintenance and repairs on spacecraft

• To conduct space tourism activities

• To test new spacesuits

What was the main issue with the Space Telescope Imaging Spectrograph?

• It was not designed to be used in space

• It was too heavy to operate

• It had hundreds of tiny screws that needed removal

• It required a new power source

How did the team make the tools more astronaut-friendly?

• By making them larger

• By using color codes for different fasteners

• By making them lighter

• By adding more buttons

What was the purpose of the fastener capture plate?

• To store extra tools

• To hold the telescope in place

• To prevent screws from floating away

• To provide a power source

How did astronauts ensure they did not lose screws during the repair?

• By using magnetic tools

• By using adhesive

• By using a fastener capture plate

• By working in pairs

What is a critical safety concern for astronauts during spacewalks?

• Getting lost in space

• Running out of food

• Damaging their gloves

• Losing communication with Earth

Why is repeated training important for astronauts?

• To increase their spacewalk duration

• To improve their physical fitness

• To develop muscle memory for safety

• To learn new languages
