STS-41B / Challenger Patch
The first untethered space walks were performed by astronauts McCandless and Stewart. First in-space use of the Manned Maneuvering Unit. West German-built Shuttle Pallet Satellite (SPAS), originally flown on STS 7, became the first satellite to be reburbished and flown again. Two satellites were successfully deployed, but failure of the satellite rocket motors left them in radical Earth orbits. Challenger landed February 11, at 8:47 AM, EST at the Kennedy Space Center, FL. The flight marked the first time the spacecraft landed at its launch site. Mission duration was seven days, 23 hours, 17 minutes. Challenger traveled 2.8 million miles in 127 orbits. Patch description: The Space Shuttle Challenger, making its fourth spaceflight, highlights the 41B insignia. The reusable vehicle is flanked in the oval by an illustration of another PAM-D assisted satellite deployment; and astronaut making the first non- tethered extravehicular activity; and eleven stars. 4" diameter embroidered patch. Availability: Usually ships within one business day.
