STS-41-C was extended one day due to problems capturing the Solar Max satellite, and the landing on April 13, 1984, took place at Edwards Air Force Base, instead of at Kennedy Space Center as had been planned.Nelson, using the Manned Maneuvering Unit (MMU), flew out to the satellite and attempted to grasp it with a special capture tool, called the Trunnion Pin Acquisition Device (TPAD).Nelson and van Hoften then began the repair operation, replacing the satellite's attitude control mechanism and the main electronics system of the coronagraph instrument.Other STS-41-C mission activities included a student experiment located in a middeck locker which found that honeybees can successfully make honeycomb cells in a microgravity environment.The 6 days, 23 hours, 40 minutes, and 7 seconds mission ended on April 13, 1984, at 5:38 a.m. PST, when Challenger landed safely on Runway 17, at Edwards Air Force Base, having completed 108 orbits.
Alternate mission patch, referencing the mission's original designation, STS-13; and landing under a black cat, given that April 13, 1984, was a Friday the 13th.
