Apollo 13 (April 11–17, 1970) was the seventh crewed mission in the Apollo space program and would have been the third Moon landing.The craft was launched from Kennedy Space Center on April 11, 1970, but the landing was aborted after an oxygen tank in the service module (SM) exploded two days into the mission, disabling its electrical and life-support system.
In fact, within hours after the accident, Apollo 13 used the lunar module to maneuver from its planned trajectory to a circumlunar free-return trajectory. [7] Apollo 13 was the only Apollo mission to actually turn around the Moon in a free-return trajectory (however, two hours after perilune, propulsion was applied to speed the return to Earth ...
The trajectory followed by Apollo 13 Sketch of a circumlunar free return trajectory (not to scale).. In orbital mechanics, a circumlunar trajectory, trans-lunar trajectory or lunar free return is a type of free return trajectory which takes a spacecraft from Earth, around the far side of the Moon, and back to Earth using only gravity once the initial trajectory is set.
A new documentary chronicling the events surrounding the Apollo 13 mission, in which three astronauts found themselves stranded in space following a catastrophic explosion, is being released on ...

Lunar Orbiter spacecraft. The Lunar Orbiter program was a series of five uncrewed lunar orbiter missions launched by the United States in 1966 and 1967. Intended to help select Apollo landing sites by mapping the Moon's surface, [1] they provided the first photographs from lunar orbit and photographed both the Moon and Earth.
Chabot Observatory calendar records an application of optical tracking during the final phases of Apollo 13, on April 17, 1970: Rachel, Chabot Observatory's 20-inch refracting telescope, helps bring Apollo 13 and its crew home. One last burn of the lunar lander engines was needed before the crippled spacecraft's re-entry into the Earth's ...
