^Lot 582 STS-41 Modular Servicing Tool

One-of-a-kind module servicing tool ‘shop test’ device, used during training for the STS-41C Solar Max repair mission. This device was used at the WETF (Weightless Environment Training Facility) at the Johnson Space Center by the crew of space Shuttle Challenger (STS-41C), in preparation of their mission objective to capture, repair, and redeploy the crippled Solar Maximum Mission satellite–‘Solar Max’—that had been launched in 1980. Device, painted light blue (aka ‘Cepi-blue’), measures 23? high, 11.5? wide and weighs in at 13.35 pounds. The device was air-driven and used an impact wrench as a drive method, as any sort of electric power could not be used in the underwater facility. Top of device bears a “NASA Goddard Space Flight Center” sticker, with a “GSFC Satellite Servicing Project Property Action Control Tag,” label affixed to the bottom, filled out in an unknown hand, “Module Servicing Tool (LT-WT),” with serial number “Proto.” In fine, used condition, with areas of missing paint, and scattered dings and dents. Accompanied by two photos of the tool, one a ‘red-numbered’ NASA photo; the other a color 8 x 10 satin-finish photo of the device interfaced with the Integrated Orbital Servicer System. The importance of this device and shuttle mission cannot be understated as no one in human history had grabbed an orbiting satellite, repaired it, and redeployed in the same mission. This trainer was integral in making that mission’s success possible.
