NASA cuts shuttle trip short


NASA is concerned Hurricane Dean is heading for Houston.

CAPE CANAVERAL, Fla. (AP) — On Saturday, NASA ordered space shuttle Endeavour back to Earth a day early out of fear that Hurricane Dean might disrupt flight operations.

The shuttle is now scheduled to depart from the international space station today, and landing is set for Tuesday.

The astronauts had hurriedly completed a shortened spacewalk Saturday and were still cleaning up from it when the decision came down from mission managers. The two crews shook hands and said goodbye, then closed the hatches between their docked spacecraft.

NASA worried the hurricane might veer toward Houston, the home of Mission Control, forcing an emergency relocation of flight controllers to Cape Canaveral. The makeshift control center there would not be nearly as good or big as the Houston operation, and that’s why managers wanted to bring Endeavour back to Earth early.

Tough to call

Hurricane Dean, a fierce Category 4 storm, was headed toward Mexico’s Yucatan Peninsula and the Gulf of Mexico. It was uncertain whether the storm might strike the Texas coastline late in the week; that uncertainty made NASA’s decision — so many days in advance — all the harder.

LeRoy Cain, who headed Saturday’s mission management team meeting, acknowledged that the hurricane’s predicted path was shifting southward and farther from Houston. But he said it would have been irresponsible for NASA not to cut the mission short, considering most everything had already been accomplished in orbit.

NASA is ready to rush a skeleton crew of flight controllers to Cape Canaveral, but only if the shuttle cannot land Tuesday for some reason and the hurricane is bearing down on Houston and threatening the city for several days, Cain said.

In 26 years of space shuttle flight, NASA never has had to call up an emergency Mission Control, although it’s been practiced.

Saw it from space

During a spacewalk that was shortened to save time, Dave Williams and Clay Anderson could see the eye of the giant hurricane as the shuttle-station complex orbited 214 miles above the Caribbean, exclaiming “oh wow” and “holy smokes.”

Williams and Anderson tackled only the most important space station maintenance chores that had been planned for the fourth and final spacewalk of Endeavour’s mission. Mission Control cut two hours from the spacewalkers’ to-do list so the hatches between the linked spacecraft could be closed late Saturday afternoon.

The two men attached a stand to the station’s exterior for a shuttle inspection boom. The stand won’t be used until next year. They also retrieved two experiments from the outside of the station for return to Earth, and hooked up antenna equipment.

NASA’s hurricane deliberations followed a decision to forgo shuttle repairs.
