Atlantis crew docks with space station
HOUSTON (AP) —The crews of Space Shuttle Atlantis and the International Space Station greeted each other with hugs and handshakes yesterday after the shuttle arrived at the orbiting outpost.
But amid the smiles and salutations, engineers in Houston 220 miles below started evaluating whether a peeled-back thermal blanket should be fixed by astronauts.
A decision likely will be made in the next day or two, and if the answer is to fix it, another decision will be made on whether it will be done during one of three scheduled spacewalks or during an extra, unplanned one.
Engineers who had studied past damage to the blanket area, located on a pod of engines near the shuttle’s tail, on other shuttle missions were uncomfortable with the safety margins of a piece of the blanket sticking out during re-entry into Earth’s atmosphere when temperatures on the shuttle’s heat shield can reach as high as 2,900 degrees during re-entry.
Temperatures at the blanket’s location reach only 700 degrees to 1,000 degrees Fahrenheit.
“The concern is that if it sticks up, you get additional heating,” said John Shannon, chairman of the mission management team.
Engineers were confident the loosened blanket was caused by aerodynamic forces during launch, not by being hit by a piece of debris during liftoff.
“Since this wasn’t an impact blow, we have high confidence that the structure beneath it is pristine,” Mr. Shannon said. “There’s no damage.”
The rest of the vehicle appeared to be in fine shape, NASA said. Sensors reported six hits on the wing during launch, but engineers were not concerned about them.
Hatches between the two spacecraft opened about 90 minutes after the shuttle docked with the space station following leak checks.
After exchanging greetings and receiving a safety briefing from Mr. Yurchikhin, both crews resumed working.
“Are you sure Clay is onboard?” Mr. Yurchikhin said.
“Yes, we checked before we launched from Florida,” Mr. Sturckow said amid laughter.
Mr. Sturckow eased the shuttle into the space station’s docking port. Latches fastened the shuttle and orbiting space lab together at 3:36 p.m. The shuttle’s two-day chase of the space station ended about 210 miles above southeastern Australia.
It was the first visit this year by a shuttle to the space station. The shuttle was delivering Mr. Anderson, the newest member of the space station’s crew, as well as a new segment to the orbiting outpost.
