Hubble Tool Time Episode 5: Servicing Mission 3B

The video features NASA astronaut John Grunsfeld and EVA engineer Ed Rezak discussing the challenges and solutions involved in servicing the Hubble Space Telescope. They highlight the 2002 mission, which involved shutting down Hubble to repair its power system. The team developed a high torque PCU tool to handle connectors in space, ensuring successful repairs. The video concludes with the successful reactivation of Hubble, emphasizing the importance of innovative tool design for space missions.

What was the primary concern when the Hubble Space Telescope was turned off during the 2002 mission?

• It might collide with another satellite.

• It would lose all stored data.

• It might not turn back on.

• It could drift away from orbit.

Why was a left-handed astronaut needed for the 2002 Hubble mission?

• To operate a specific tool designed for left-handed use.

• To access connectors located on the left side of the instrument.

• To balance the team of astronauts.

• To test new ambidextrous gloves.

What was the main limitation of the existing tools for handling connectors in space?

• They were too heavy to carry.

• They were not compatible with the spacesuit.

• They consumed too much power.

• They required two hands to operate.

What was the key feature of the high torque PCU power control unit connector tool?

• It was designed for right-handed astronauts.

• It was simple and easy to use with gloved hands.

• It was motorized with computer chips.

• It had a built-in camera for precision.

How did the new tool prevent itself from floating away in space?

• It had a tether loop attached to the astronaut.

• It was magnetized to attach to the telescope.

• It was stored in a special compartment.

• It was controlled remotely from Earth.

What was the outcome after the new connectors were installed and the power was turned back on?

• The Hubble's data was lost.

• The Hubble required additional repairs.

• The Hubble resumed its operations successfully.

• The Hubble failed to restart.

What material was used on the tool to ensure a good grip on the connectors?

• Rubber

• Plastic

• Metal

• Silicone
