Apollo 13 more immediate and visible warnings of anomalies. Because Apollo 13 followed the free-return trajectory, its altitude over the lunar far side was approximately greater than the orbital altitude on the remaining Apollo lunar missions. The Moon was almost at apogee during the mission (as it also was during the flights of Apollo 10 and Apollo 15), which also increased the distance from the Earth. The combination of the two effects ensures that Apollo 13 holds the absolute altitude record for a manned spacecraft, reaching a distance of from Earth on 7:21 pm EST, April 14, 1970. The A7L spacesuit intended
Apollo program stages, carrying dummy upper stages filled with water. The first flight with a live S-IV was launched from LC-37. This was followed by five launches of boilerplate CSMs (designated AS-101 through AS-105) into orbit in 1964 and 1965. The last three of these further supported the Apollo program by also carrying Pegasus satellites, which verified the safety of the translunar environment by measuring the frequency and severity of micrometeorite impacts. In September 1962, NASA planned to launch four manned CSM flights on the Saturn I from late 1965 through 1966, concurrent with Project Gemini. The payload capacity would have severely
