Tuesdays starting on April 16, 2019, we will be releasing a new six-part mini-series about the tools used on Hubble's servicing missions, hosted by retired NASA astronaut John Grunsfeld.
Hubble was uniquely designed to be serviced in space so that components could be repaired and upgraded. Astronauts performed challenging spacewalks on five servicing missions from 1993 to 2009 to keep Hubble operating so that it could change our fundamental understanding of the universe.
In addition to enabling Hubble's scientific discoveries, the tools developed by teams at NASA's Goddard Space Flight Center and tested with the Johnson Space Center furthered NASA's human exploration capabilities. These tools and the knowledge gleaned from the Hubble servicing missions are used today by astronauts on the International Space Station, and will be critical to NASA's future crewed missions to the moon and Mars.
