Galileo takes the plunge

GalileoAfter five months of independent flight, the Galileo atmospheric probe slams into the atmosphere of giant planet Jupiter at a speed over 100,000mph, burrowing over a hundred miles into the huge planet’s dense atmosphere before the heat of entry and the atmospheric pressure crush the probe. Deploying a parachute to slow its descent, the probe survives for nearly an hour, its sensors finding a surprisingly dry atmosphere. As it plummets toward the center of Jupiter, the Galileo probe registers 450mph winds, but never finds any hints of anything resembling a solid surface. The sum total of the probe’s sensor readings – the entirety of our data gathered directly within the atmosphere of Jupiter – tops out at 460 kilobytes of data.

Mission accomplished! Now keep going.

GalileoBeating the odds imposed upon it by the unforgiving environment around the planet Jupiter and its major moons, and engineering challenges such as a high-gain antenna that never unfurled properly after its 1989 launch, NASA’s Galileo space probe completes its two-year mission. Since the spacecraft is still intact and reasonably healthy, NASA gains a two-year extension, which it calls the Galileo Europa Mission, focusing on the two innermost large moons, icy Europa and volcanic Io. Trajectories are planned to fly Galileo even closer to these moons than ever before, though the harsh radiation zone around Jupiter itself could fry Galileo’s main computer and end the mission at any time.

The longest-serving astronaut retires

Gemini 3A 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.

AKATSUKI arrives at Venus

Akatsuki at VenusThe Japanese space probe AKATSUKI, launched in 2010 but left in an orbit around the sun by an engine glitch, catches up with its original target, the planet Venus, and fires its attitude control thrusters. The lengthy engine burn slows AKATSUKI enough to be captured by Venus’ gravity, in an elliptical 13-day orbit that brings the probe within 250 miles of the Venusian clouds it was sent to study at its closest, and nearly a quarter million miles away from the planet at the furthest. Another engine burn is planned for March 2016 to circularize and shorten AKATSUKI’s orbit so it can begin its observations of the planet’s weather patterns.
