When a rubella scare grounded Command Module pilot Ken Mattingly in 1970, he was forced to watch from the sidelines as his two crewmates headed off to the Moon without him on the ill-fated Apollo 13. Two years later in 1972, Mattingly hoped for better luck on his new mission, Apollo 16. Unfortunately, while Apollo 13 had been an Oscar-worthy triumph over tragedy, Apollo 16 would turn out to be something of a farce.
In 1972, morale at NASA was low. A curtailed Apollo programme was heading into its final two missions and many staff members were being laid off. Meanwhile, the Soviets were making headlines with the Lunokhod rover and its robotic sample return missions, doing the work of the Apollo missions at a fraction of the cost and without risking human lives.
Not that the Apollo astronauts themselves minded the risk. In fact, they were pushing for more adventurous missions following the success of Apollo 15. Perhaps to the rugged landscape of the southern pole? Or even the lunar far side. Instead, NASA played it safe, and the fifth lunar landing was set to visit the equatorial lunar highlands for the first time. And so, on 16 April at 17:54 UT, Mattingly along with Commander John Young and Lunar Module Pilot Charles Duke launched on their way to Descartes crater, an area believed to be the site of past volcanic activity.
Though the launch went well enough, it wasn't long before the first of Apollo 16's many problems began. On the second day, as the crew were mounting the Lunar Module on the nose of the Command and +Service Module (CSM) and removing the former from its housing, Mattingly noticed a steady stream of white particles flowing from the Lunar Module's propellant tanks. Were they venting fuel?
"I think you're going to have to get in the Lunar Module and take a look at the... systems' gauges to tell what's going on here," came the order from the ground.

Could We Find Aliens by Looking for Their Solar Panels?- Designed to reflect ultraviolet and infrared, the panels have a unique fingerprint
Researchers searching for life beyond Earth spend a lot of time thinking about what telltale signs might be detectable astronomically. Forms of unambiguous evidence for the presence of life on another world are known as biosignatures. By extension, techno signatures are indicators of activity by intelligent, civilisation-building life.
Antimatter- In our continuing series, Govert Schilling looks at antimatter, the strange counterpart to most of the matter filling our Universe
Particles and corresponding antiparticles are very much alike, except they have opposite electrical charges. For instance, the antiparticle of the electron - known as the positron - has the same tiny mass, but while electrons carry a negative electrical charge, positrons are positively charged.
Where Have All The Milky Way's Early Stars Gone?- Our Galaxy has a curious lack of pristine stars
The Big Bang produced a Universe filled almost exclusively with hydrogen and helium; all other elements - what astronomers call metals - were produced by stars, supernovae and everything that happens later. So if you can pick out a pristine star with no metals polluting it from among the billions in the Milky Way, then you are likely to have a star dating from our Galaxy's earliest days.
