Hubble Tool Time Episode 4: Servicing Mission 3A

The video features NASA astronaut John Grunsfeld and engineer Ahmed Rezak discussing the Hubble Space Telescope's challenges and solutions. In 1998, Hubble's gyroscopes failed, leading to a split mission to replace them. The video details the difficulties faced by astronauts during the servicing mission, including working in tight spaces and avoiding damage to sensitive instruments. The team successfully replaced the gyroscopes and made additional upgrades. An innovative tool was developed, inspired by a simple pick stick, to ease the task. The video concludes with a light-hearted exchange.

What was the primary reason for splitting the Hubble servicing mission into 3A and 3B?
