How Hubble’s Servicing Mission 3A Saved the Day

The video discusses the history and significance of Hubble's servicing missions, focusing on the challenges and successes of Servicing Mission 3A. It explains the critical role of gyroscopes in Hubble's operations and how their failure led to the mission being split into two parts. The video highlights the successful execution of SM 3A, which included replacing gyroscopes and upgrading Hubble's systems, ensuring the telescope's continued scientific contributions. The video concludes with a festive message from the narrator.

Why was there a discrepancy in the numbering of Hubble's servicing missions?

• Servicing Mission 3 was split into two parts due to gyroscope failures.

• Servicing Mission 4 was canceled and then reinstated.

• The missions were named after the astronauts involved.

• The missions were named based on the year they were launched.

What role do gyroscopes play in Hubble's operations?

• They provide data for scientific experiments.

• They maintain the telescope's orientation in space.

• They help in focusing the telescope's lens.

• They power the telescope's solar panels.

What was the main priority of Servicing Mission 3A?

• Repairing the telescope's mirror.

• Upgrading the solar panels.

• Replacing all the gyroscopes.

• Installing a new camera.

What was one of the challenges faced by the SM 3A team?

• Lack of funding for the mission.

• Shortage of astronauts for the mission.

• Limited time for training due to the mission split.

• Inability to communicate with Hubble.

What upgrades were made to Hubble during the SM 3A mission?

• A new mirror and lens system.

• A more advanced computer and new insulation panels.

• A new camera and solar panels.

• A new propulsion system.

When was Servicing Mission 3B successfully completed?

• October 1999

• May 2009

• March 2002

• December 1999

What was the outcome of the final servicing mission in 2009?

• Hubble was replaced by a new telescope.

• Hubble was upgraded for continued scientific research.

• Hubble was moved to a new orbit.

• Hubble was decommissioned.
