NASA has just announced it will postpone the 39th and final launch of space shuttle Discovery until November 30 at the earliest, after a hydrogen gas leak stalled this afternoon's scheduled liftoff.
Meanwhile, Robonaut, who was supposed to start his career as the first humanoid robot in space this week, remains shut in his custom SLEEPR crate while the shuttle sorts out its problems.
Perhaps its sentimentality that's making Discovery stall its 39th and final mission. Scheduled to launch at 3:04 p.m. today after four days of delays for reasons ranging from helium and nitrogen leaks to voltage irregularities to stormy weather, the shuttle began leaking hydrogen fuel this morning midway through the fueling process.
NASA engineers are still working to figure out exactly what caused a brief, one-time irregular power drop to one of the main engine controllers on the shuttle Discovery. But even if they fix the glitch the thrice-delayed mission faces an 80 percent chance of being delayed by weather tomorrow, Kathy Winters – NASA's appropriately named shuttle weather officer – says.
An electrical issue affecting a main engine computer controller has prompted NASA mission managers to postpone the launch of the Space Shuttle Discovery's final mission to Thursday at 3:29 p.m. EDT, further delaying a launch that has been pushed back twice already.
Let the 3-D deluge begin! The New York Times reports today that Discovery is partnering with Imax and Sony to create an all 3-D all the time HDTV station in 2011. The partnership is due to be announced officially this week at CES, which we'll be covering live starting tomorrow. I'm going to start calling it 3-D-E-S from this moment forward.
NASA has wanted to get a better look at its space shuttle landings ever since the tragic disintegration of space shuttle Columbia in 2003. Part of the space agency's solution: a modified Navy aircraft that can take 10,000 to 15,000 images of space shuttles traveling at a few miles per second.
Space shuttles have about 10,000 thermal tiles that protect their underbelly and wings during the white-hot descent from orbit. A protective layer of air molecules forms around the shuttle with temperatures up to 3,000 degrees F -- still mild compared to temperatures of more than 9,900 degrees F beyond the boundary layer.

Several Florida residents have reported seeing the Leptotyphlops microsnake long before it was announced as a new species, which herpetologist Blair Hedges named for his wife.
Readers want to know: how can you tell if the new animal or plant you've stumbled across is a unique, as of yet unnamed species?
Do you know the answer?

It's a scene reminiscent of NASA's glory days, back when men still walked on the moon. A space capsule descends under a canopy of three orange-and-blue parachutes, swaying gently in the breeze. The spacecraft splashes down in the Pacific at a leisurely 15 miles an hour, and the chutes settle into the water beside it. A recovery boat rumbles into position beside the spacecraft, and divers hit the water.
