The STS-125 astronaut crew performed five back-to-back spacewalks to repair and service the Hubble Space Telescope. The tasks completed on these spacewalks extended the operational lifetime of HST through 2014. The success of the mission depended on the spacesuits, tools and skills that were used to repair Hubble and the people of NASA who make this all happen.

Spectacular sights, unexpected insights — the Hubble Space Telescope has brought both. Image Credit: USA Today

This six-week project asks student teams of four to design an astronaut tool that could fix a problem on the Hubble Space Telescope. The project encourages individual responsibility, collaboration and creativity; it requires integrated and experiential learning and concludes with the submission of a project portfolio that documents and demonstrates student accomplishments.

Teach students critical skills with this interactive activity based on Servicing Mission 3B. Image Credit: NASA

Students use critical thinking and reading skills by searching for word and picture clues from the events of the 2002 Servicing Mission 3B, including the shuttle launch and spacewalks to place mission events in the correct sequence.

Goddard Engineers and Divers Multi-Task for Hubble

How do NASA astronauts prepare for Hubble Space Telescope servicing missions? The planning can be tedious and the preparation involves a lot of time. The astronauts spend many hours practicing on intricate, full-sized models of the telescope. More information about training is available here.

Servicing Mission 4 astronaut Andrew Feustel trains with fellow astronauts and Hubble engineers in the clean room at NASA's Goddard Space Flight Center. Feustel is using a computer-controlled power tool, called the Pistol Grip Tool, to install the Wide Field Camera 3 into a high-fidelity Hubble model. Image Credit: NASA

The Crew Aids and Tools team at NASA's Goddard Space Flight Center is responsible for designing and manufacturing special equipment for astronauts to use on Hubble servicing missions. Engineers have been working on custom tools and other aids that astronauts will need as they make necessary upgrades and repairs to the famed observatory.
