40 year-old NASA science satellite falls harmlessly from sky off Alaska

After almost 40 years circling Earth, a retired NASA science satellite plunged harmlessly through the atmosphere off the coast of Alaska, NASA reported Monday. The Defense Department confirmed that the satellite - placed in orbit in 1984 by astronaut Sally Ride - reentered late Sunday night over the Bering Sea, a few hundred miles from Alaska. NASA said it's received no reports of injury or damage from falling debris. Late last week, NASA said it expected most of the 5,400-pound (2,450-kilogram) Earth Radiation Budget Satellite to burn up in the atmosphere, but that some pieces might survive. The space agency put the odds of falling debris injuring someone at 1-in-9,400. Space shuttle Challenger carried the satellite into orbit and the first American woman in space set it free. The satellite measured ozone in the atmosphere and studied how Earth absorbed and radiated energy from the sun, before being retired in 2005, well beyond its expected working lifetime.

NASA fuelling new moon rocket for launch after leaks, hurricanes

NASA began fuelling its new moon rocket on Tuesday for a middle-of-the-night launch, its third try to put an empty capsule around the moon for the first time in 50 years. Fuel leaks plagued the first two attempts in late summer, then a pair of hurricanes caused more delays. While engineers never pinpointed the cause of the escaping hydrogen, they altered the fuelling process to minimise leakage and were confident that all the plumbing in the 322-foot (98-metre) rocket would remain tight and intact. NASA added an hour to the operation to account for the slower fill-up, vital for reducing pressure on the fuel lines and keeping the seals in place. It seemed to work, with no major leakages reported during the early stages. "So far, everything is going very smoothly," said assistant launch director Jeremy Graeber about an hour into fuelling. The rocket was being gassed up with nearly one million gallons (3.7 million litres) of super-cold hydrogen and oxygen. After more than four hours,
