Image: Capturing the Solar Maximum Mission satellite

Description: Launched April 6, 1984, one of the goals of the STS-41C mission was to repair the damaged free-flying Solar Maximum Mission Satellite (SMMS), or Solar Max. The original plan was to make an excursion out to the SMMS and capture it for necessary repairs. Pictured is Mission Specialist George Nelson approaching the damaged satellite in a capture attempt. This attempted feat was unsuccessful. It was necessary to capture the satellite via the orbiter's Remote Manipulator System (RMS) and secure it into the cargo bay in order to perform the repairs, which included replacing the altitude control system and the coronograph/polarimeter electronics box. The SMMS was originally launched into space via the Delta Rocket in February 1980, with the purpose to provide a means of studying solar flares during the most active part of the current sunspot cycle. Dr. Einar Tandberg-Hanssen of Marshall Space Flight Center's Space Sciences Lab was principal investigator for the Ultraviolet Spectrometer and Polarimeter, one of the seven experiments of the Solar Max.
