This video uses data gathered from the Lunar Reconnaissance Orbiter spacecraft to recreate some of the stunning views of the Moon that the Apollo 13 astronauts saw on their perilous journey around the farside in 1970. These visualizations, in 4K resolution, depict many different views of the lunar surface, starting with earthset and sunrise and concluding with the time Apollo 13 reestablished radio contact with Mission Control. Also depicted is the path of the free return trajectory around the Moon, and a continuous view of the Moon throughout that path. All views have been sped up for timing purposes.

The story of Apollo 13 goes beyond a tale of survival. The mission also successfully completed a science 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. This video highlights the beginning and end of that impact experiment, and shows how current data and imagery from NASA’s Lunar Reconnaissance Orbiter mission helps us better interpret and analyze the results.
This video not only contains archival footage captured by the crew of Apollo 13, but also newly-uncovered audio of a humorous exchange between astronauts Jim Lovell, Fred Haise, and Capcom Vance Brand at Mission Control. This booster impact experiment audio had been recorded and sent to the National Archives and Records Administration in 1970, but was unplayable at that facility due to differences in audio equipment, so it sat in storage. The only machine capable of playback is located at NASA’s Johnson Space Center, but that equipment had been out of service for decades. In 2015 an effort funded by the National Science Foundation saw the equipment refurbished, and all 7,200 hours of Apollo 13 audio was digitized. This material was first made publicly available in early 2020 at ApolloInRealTime.org. Among this never-before-heard material we were able to find the conversation covered in this video.
This video also utilizes images from the Lunar Reconnaissance Orbiter Camera (LROC) as well as a data visualization of the Moon showing the locations of the booster impact experiment relative to the Apollo 12 seismometer station. The network of seismometers set up during the Apollo era, combined with data from the LRO mission, is teaching us about moonquakes and the interior structure of the Moon. This information will be useful to all future NASA missions to the lunar surface.

During the Apollo 13 mission, after the explosion of an oxygen tank crippled the Service Module, the astronauts had to abandon the third Moon landing. The Apollo 13 crew used the Lunar Module as a lifeboat. The Lunar Module was jettisoned by the Command Module just prior to re-entry.
A team of engineers from the University of Toronto Institute for Aerospace Studies (UTIAS) played a key role in the separation of the Lunar Module and the Command Module. As the tunnel connecting the two modules was pressurized, the UTIAS team had to determine how much pressure was necessary to safely separate the modules. Not an easy task considering the fact that if there was too much air in the tunnel, the explosion that triggered the separation would have damaged the hatch of the Command Module, and the astronauts would not have survived the re-entry.
The Apollo 13 astronauts, Commander James A. Lovell, Command Module Pilot John L. Swigert, and Lunar Module Pilot Fred W. Haise, were recovered by the U.S.S. Iwo Jima in the South Pacific after splashing down on April 17, 1970.
If you are in Toronto next Tuesday, on April 13, 2010, you can meet some of the members of the UTIAS team at the Canadian Air and Space Museum. They will receive the Pioneer Award for their role in the Apollo 13 rescue.
