NASA | Update: Hubble SM4 Flight Day 4

The video provides an update on the STS 125 mission, focusing on the first spacewalk activities, including the replacement of the Wide Field Planetary Camera 2 with a new generation camera. It also covers the installation of a new command data handling package and a 19-year-old flight spare computer. The video highlights the successful completion of tasks, preparations for future spacewalks, and the installation of a soft capture mechanism for potential future robotic servicing. Additionally, it discusses the replacement of Hubble's gyroscopes and batteries to extend its operational life, ensuring continued scientific observations.

What were the two major activities during the first spacewalk of the STS 125 mission?

• Replacing the wide field Planetary Camera 2 and installing a new command data handling package
