The story of Apollo 13 (called a “successful failure” by the mission commander Jim Lovell) goes beyond a tale of survival. The mission also successfully completed a scientific investigation that is still helping to inform our understanding of the Moon to this day. Early in Apollo 13’s voyage, Mission Control sent the spacecraft’s empty S-IVB rocket booster on a collision course with the lunar surface, where a seismometer set up by the Apollo 12 mission would measure the tremors.
The video below, published by NASA Goddard Channel contains archival footage captured by the crew & newly-uncovered audio. It highlights the beginning and end of that impact experiment and shows how current data and imagery from NASA’s Lunar Reconnaissance Orbiter mission help us better interpret and analyze the results.
