Hubble was uniquely designed to be serviced in space so that components could be repaired and upgraded. Astronauts using custom-designed tools 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.Join John, EVA engineer Ed Rezac, and astronaut trainer Christy Hansen in this episode of Hubble Tool Time to learn about creating a Fastener Capture Plate to capture 111 screws in order to repair the Space Telescope Imaging Spectrograph on Servicing Mission 4 in 2009.In addition to enabling Hubble's scientific discoveries, the tools developed by teams at NASA's Goddard Space Flight Center and tested in collaboration 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.For more information, visit https://nasa.gov/hubble.Credit: NASA's Goddard Space Flight Center/Katrina Jackson.Music credits: \"Wine On It\" by Kevin Blanc [SACEM]; KTSA Publishing SACEM; Gum Tapes; Killer Tracks Production Music. \"Breakthrough\" by Donn Wilerson [BMI]; Killer Tracks BMI; Killer Tracks Production Music. || ",

            "description": "Battery Modules.  The six batteries currently on board the observatory are all original equipment. After more than 17 years of continuous operation the batteries are degrading. In the current condition, the Hubble electrical power system requires careful management of system state of charge to assure adequate power margins for all operational scenarios. This will become more difficult, and will start to constrain operations. The replacement of the two Hubble battery modules (each containing three batteries) will rejuvenate the electrical power system. This, combined with the power system enhancements made in Servicing Mission 3B, will result in ample power margins for the remainder of Hubble's lifetime. || ",
