NASA skips Discovery's 1st landing attempt
(AP)
Updated: 2005-08-09 15:58

Good conditions were expected at Edwards, while rain was in the forecast for White Sands.

NASA prefers landing shuttles at the same place where it launches them, to avoid the several days and estimated $1 million needed to ferry the spacecraft back from the West Coast atop a modified jumbo jet.

Monday's delay disappointed astronauts' families, who anxiously awaited Discovery's return. The mission, originally intended to last 12 days, has now spanned 14.

Discovery has enough fuel and supplies to stay in orbit until Wednesday, but NASA wants to hold out that option only if a technical problem arises.

Discovery is the first shuttle to return to orbit since Columbia's catastrophic re-entry in 2003. But Discovery's launch and flight to the international space station could be the last for a long while.

NASA grounded the shuttle fleet after a nearly 1-pound chunk of insulating foam broke off Discovery's external fuel tank during its July 26 liftoff 錕斤拷 the very thing that doomed Columbia and was supposed to have been corrected.

Discovery spent nine days hitched to the space station, where astronauts resupplied the orbiting lab and removed broken equipment and trash 錕斤拷 one of the main goals of the mission.

Another day was added to the mission when NASA grounded its fleet so astronauts could do additional work on the station. Discovery was the first shuttle to visit the orbiting outpost since 2002.

As a result of Columbia, Discovery's crew performed intense inspections of their ship on five different days. Astronauts also did a spacewalk to test new repair techniques and replaced a failed gyroscope on the station during another spacewalk.

In a third, unprecedented spacewalk, two protruding thermal tile fillers were removed from Discovery's belly. Engineers feared the material could cause dangerous overheating during re-entry.

Columbia was doomed by a 1.67-pound piece of foam that broke free from an external fuel tank at launch. The foam pierced a hole in the ship's left wing, and as the spacecraft re-entered the Earth's atmosphere, searing gases melted the wing from the inside. All seven astronauts aboard were killed.

Former shuttle astronaut Charles Bolden said there comes a time when every astronaut is ready to return home 錕斤拷 no matter how risky the ride.

"You always want to stay in space. You don't ever want to come home, but you invariably get homesick," he said. "With every orbit that you don't come home, it gets more and more frustrating."
