A veteran of the Gemini, Apollo and shuttle programs, 74-year-old astronaut John Young retires from NASA, capping off a 42-year career with the space agency. Young joined NASA in 1962 after hearing President Kennedy’s historic directive to launch a manned mission to the moon, and only three years later Young flew with Mercury veteran Gus Grissom on Gemini 3, the first manned two-person NASA mission. Young commanded Gemini 10 in 1966, was the command module pilot for the moon-orbiting Apollo 10 mission, and in 1972, Young commanded Apollo 16, landing in the moon’s mountainous Descartes region. Young commanded the first space shuttle mission, the maiden flight of Columbia in 1981, and commanded the ninth shuttle flight in 1983. Young had also served as the Chief Astronaut, determining crew assignments and making personnel decisions. In the wake of the Challenger disaster in 1986, Young became one of NASA’s most outspoken critics, and was reassigned to the position of special assistant for engineering, operations and safety – a move he regarded as a political one.

NASA orders the crew of the International Space Station to cut back on meals. Without the Space Shuttle delivering supplies to the station, resupply missions have been flown only by Russia’s much smaller unmanned Progress capsules, but the station was never designed to be restocked by Progress alone. Astronaut Leroy Chiao and cosmonaut Salizhan Sharipov are ordered to cut back on calories – with a reduction in workload to match – until more food arrives on a Progress capsule scheduled for liftoff on Christmas Eve. A failure of that flight could lead to an order to abandon the station.

Launched ahead of its identical twin, Voyager 1, in 1977, NASA’s Voyager 2 spacecraft surpasses its 10,000th day in deep space. At 11 billion miles from Earth, Voyager 2 is one of the most distant human-made objects in space, surpassed only by Voyager 1. Both Voyagers are expected to function well into the 2020s, and are expected to have left the solar system to enter interstellar space by then.
Astronomers at Palomar Observatory discover a body beyond Neptune’s orbit that initial observations show is larger than Pluto. Eris is quickly dubbed the tenth planet by the media and the scientific community, and it is later found to have a small moon of its own in a close orbit, which is later named Dysnomia. But events overtake Eris and Dysnomia before the science textbooks have a chance to be rewritten to include a tenth planet: Eris becomes a case study in an ongoing debate within the International Astronomical Union about the definition of a planet. In 2006, the IAU will establish a set of parameters which determine that Eris isn’t a planet – and then rewrites the history books by deciding that Pluto isn’t either.
After months of delays in development of its elaborate guidance software system, NASA’s Deep Impact unmanned space probe is launched on a mission to intercept, and fire an impactor into, Comet Tempel 1 half a year later. In order to catch up with the comet, Deep Impact is lofted into orbit by a Delta II rocket, which puts the spacecraft on a precise course at a speed of roughly 64,000mph. Deep Impact will fire the impactor into the comet in July to study the distribution and composition of the debris scattered by the resulting impact.
The European Space Agency’s Huygens probe successfully lands on Saturn’s largest moon, Titan, gathering measurements and taking mind-boggling images from the sky all the way down to the surface. Perhaps the biggest discovery of the initial pictures is an aerial view of what appear to be tributaries leading to a large body of liquid – an almost delta-like region as viewed from the sky. (Thanks to Titan’s thick atmospheric haze, its surface has never before been seen.) Huygens itself manages to touch down on dry land, on a plain scattered with chunks of ice, slowed to only 15 miles per hour by parachutes during its descent (despite upper-level winds estimated at around 300mph). Even if Huygens had splashed down in a body of liquid, the probe is designed to stay afloat.
