Labels:text | screenshot | font | document OCR: b. In April 1983, two members of the Space Shuttle Challenger crew, Story Musgrave and Donald Peterson, performed an extravehicular activity (an activity outside the spacecraft) while Challenger was at an altitude of 280 km. What fraction of Earth did they see? ( Use 6380 km for the Earth's radius.) Solution: For h = 280 and R = 6380 Az 280 Ap = 2(6380 + 280) = 0.021, or 2.1 percent. (Continued on next card.)
