STS006-45-111 (7 April 1983) --- Astronaut Donald H. Peterson (port side) and F. Story Musgrave, STS-6 mission specialists, evaluate the handrail system on the starboard longeron and aft bulkhead, respectively, during a long extravehicular activity (EVA) aboard the Earth-orbiting space shuttle Challenger. The vertical stabilizer and orbital maneuvering system (OMS) pods frame a portion of Mexico?s state of Jalisco below. Punta Farallon and Sahta da Tencatita, about 120 kilometers (75 miles) south of Puerto Vallarta, are visible. Pacific waters form about half of the backdrop for this scene, photographed by one of two crew members who remained inside the spacecraft during the EVA. Astronaut Karol J. Bobko, pilot, took a number of pictures of his fellow crew members during their outside tasks and astronaut Paul J. Weitz, commander, took some photographs while remaining in command of the reusable vehicle. Photo credit: NASA
