Power outage interrupts Atlantis space walk

A partial power outage at the International Space Station briefly interrupted today's spacewalk, knocking out robotic camera views of the two astronauts as they worked to install a spare antenna.
The outage happened two hours into the 7 1/2-hour spacewalk by Atlantis crewmen Garrett Reisman and Stephen Bowen. The space station's main command-and-control computer suddenly crashed. A backup computer kicked in, but power temporarily was lost to some equipment, including the video monitors being used by the robot arm operator, Piers Sellers.
Reisman was perched on the end of the space station's 58-foot robot arm when Sellers lost his camera views. Bowen was working with connectors on the space station's framework. The lead flight director later said that may have inadvertently contributed to the computer shutdown.
NASA said neither spacewalker was ever in any danger. In 10 to 15 minutes, everything was back to normal, although the backup computer remained in charge.
"Ah, much better," Sellers said when his camera views came back.
The spacewalkers then had to contend with a tough connector and refasten some bolts. A few hours later, the 6-foot dish antenna and its boom finally were installed on the space station. Bowen proudly shook the 14-foot structure. "It doesn't wobble anywhere," he reported.
A tiny gap remained between the dish and boom, however, and Mission Control had the astronauts strap the assembly down as engineers analyzed the situation. Locks on the antenna also were not removed, as an extra precaution.
Lead flight director Emily Nelson said she needs to know from the structural engineering team in the next day or two whether the antenna will need more work during an upcoming spacewalk.
The astronauts also hooked up a storage platform for the station's Canadian-built robot, named Dextre, and loosened the bolts on six batteries that will be replaced on the next two spacewalks. They jokingly asked for more work as the spacewalk went into an hour of overtime.
"You guys might not be tired, but I'm done," said Dominic "Tony" Antonelli, who monitored everything from inside.
Reisman spent the entire spacewalk on the end of the robot arm, and enjoyed the ride.
"I'm way the heck up here now," Reisman called out from his perch. "I might only be about 5-foot-4, but right now, I think I'm the highest person around. Woooo!"
"Yeah, like you're two-thirds of the way up of being like a Hubble guy," replied astronaut Michael Good from inside the space station. Good worked on the Hubble Space Telescope last May in a considerably higher orbit.
Shuttle Atlantis and its crew of six delivered the antenna and other spare parts to the space station Sunday. NASA wants to stockpile as much equipment at the orbiting complex as possible before the shuttle program ends.
Only two more shuttle missions remain. For Atlantis, though, this is it.
NASA may add an extra chore to the second or third spacewalk coming up this week. A cable is snagged at the end of the shuttle's inspection boom. Mission managers said it should be a quick and easy job to free it. The problem prevented the shuttle crew from properly checking Atlantis over the weekend for launch damage.
Mission managers will wait before deciding whether the shuttle astronauts, while still at the station, must check the sections of the left wing and other areas that were missed in Saturday's survey.
The crew will take on another major objective Tuesday, attaching a new Russian-built compartment to the space station.smile

reasury takes $1.6 billion loss on Chrysler loan

The Treasury Department said Monday it will lose $1.6 billion on a loan made to Chrysler in early 2009.
Taxpayer losses from bailing out Chrysler and General Motors are expected to rise as high as $34 billion, congressional auditors have said.
Treasury said Monday that Chrysler repaid $1.9 billion of a $4 billion loan, which was extended before the company filed for Chapter 11. The government hopes to get another $500 million from the company that emerged from bankruptcy, Chrysler Group LLC.
The original loan was made in January 2009, when the Bush administration was scrambling to rescue Chrysler, GM and their auto financing arms.
The Congressional Budget Office estimated in March that the government's $85 billion bailout of the automakers would cost taxpayers $34 billion.
Much of it will depend on how much the government recovers from its eventual sale of nearly 61 percent of GM and about 10 percent of Chrysler.
GM has said it could conduct a public stock offering later this year. Chrysler officials have said a public stock offering is not likely before 2011.
The Treasury Department made the announcement about the loss from Chrysler on a day when GM reported its first quarterly profit in nearly three years. That moved GM closer to a stock offering that would repay at least part of the $43 billion it owes the government.
GM on Monday announced it had made net income of $865 million, or $1.66 a share, in the first quarter. That compared with a loss of $6 billion, or $9.78 a share, a year earlier. Debt and other expenses were cut by its stay in bankruptcy court last year. Strong new-model sales also helped, GM said.apple
