[edit] Introduction

The crew members: John W. Young, commander; Ken Mattingly, command module pilot; and Charles Duke, lunar module pilot. It was a J-class mission, featuring a Lunar Rover. It brought back 94.7 kg of lunar samples. It included three lunar EVA: 7.2 hours, 7.4 hours, 5.7 hours and one trans-earth EVA of 1.4. This was only the second trans-earth EVA ever and was used to bring in film from exterior cameras and conduct an experiment on microbial survival.

The Apollo 16 subsatellite was launched from the CSM while it was in lunar orbit. The subsatellite carried out experiments on magnetic fields and solar particles. It was launched April 24, 1972 at 21:56:09 UTC and orbited the Moon for 34 days and 425 revolutions. It had a mass of 80 lb (36.3 kg) and consisted of a central cylinder and three 1.5 m booms.

En route to the moon, the Apollo 16 astronauts took several photos of Earth. One of which was with North America in the background, with much of the northern portion of the continent under extensive cloud cover.

[edit] Mission highlights

A malfunction in a yaw gimbal servo loop in the main propulsion system of the CSM Casper caused concerns about firing the engine to adjust the CSM's lunar orbit, and nearly caused the Moon landing to be scrubbed. But it was decided that the malfunction presented relatively little risk, and Young and Duke (who were already undocked, and flying LM Orion when the problem occurred) were permitted to land on the Moon. However, the mission was shortened by a day (reducing the time in orbit around the Moon after the LM left the Moon and docked with the CSM), as a safety measure.

Young and Duke spent three days exploring the Descartes highland region, while Mattingly circled overhead in Casper. The astronauts discovered that what was thought to have been a region of volcanism was actually a region full of impact-formed rocks (breccias). Their collection of returned specimens included an 25 pound (11.7 kg) chunk that was the largest single rock returned by the Apollo astronauts^[2] (nicknamed Big Muley after Bill Muehlberger, principal investigator for the mission's geology activities^[3]). The Apollo 16 astronauts also conducted performance tests with the lunar rover, at one time getting up to a top speed of 11 miles per hour (18 kilometers per hour), which still stands as the record speed for any wheeled vehicle on the Moon (listed as such in the Guinness Book of Records).

[edit] Relics

The command module is currently at the U.S. Space & Rocket Center, in Huntsville, Alabama. The lunar module ascent stage separated 24 April 1972 but a loss of attitude control rendered it out of control. It orbited the Moon for about a year. Its impact site on the Moon is unknown.

[edit] Mission insignia

The circular patch featured an eagle with wings outstretched, perched atop a red, white, and blue shield, over a lunar surface. The vector symbol from the NASA logo was placed on top of the shield, and then across the shield were written the words APOLLO 16. The artwork was bordered in white, with a blue band carrying 16 stars and the crew names. There was a gold border. The patch was designed by NASA artist Barbara Matelski.

[edit] Trivia

Charles Duke left a plastic-encased photo portrait of his family on the moon. As a photograph, it could not be interpreted as 'art' (such as Fallen Astronaut).

John Young was caught twice using profanity on the moon when (a) he was complaining about drinking orange juice while on open mike and (b) when he tripped over the cable connected to the Heat Flow Experiment, pulling it out and rendering the experiment non-operational.

Merle Haggard's music was brought along at the request of the crew.

[edit] Quotes

"I mean, I haven't eaten this much citrus fruit in 20 years. And I'll tell you one thing, in another 12 days, I ain't never eating any more," John Young, reacting to stomach problems caused by drinking extra orange juice (to prevent a mineral deficiency identified in crew of Apollo 15).
