After more than a month's delay, space shuttle Endeavour and seven astronauts thundered into orbit Wednesday on a flight to the international space station, hauling up a veranda for Japan's enormous lab and looking to set a crowd record.
Success came on launch try No. 6, on the eve of the 40th anniversary of the liftoff of man's first moon landing.
But the mood was dampened somewhat when NASA managers watched the launch video.
Eight or nine pieces of foam insulation came off the external fuel tank during liftoff, and the shuttle was hit at least two or three times, said Bill Gerstenmaier, NASA's space operations chief. Some scuff marks were spotted, but that probably is coating loss and considered minor, he said.
In fact, Mission Control told the astronauts Wednesday night that the damage — which occurred not quite two minutes into the flight — looked to be less extensive than what occurred on the last flight. The impacts were around the edge of the shuttle where the right wing joins the fuselage.
Engineers immediately began reviewing all the launch pictures, standard procedure ever since flights resumed following the Columbia disaster. Gerstenmaier said zoom-in photos will be taken of the entire shuttle right before it docks with the space station Friday, to ascertain whether it suffered any serious damage. It will take days to go through all the data.
"The bottom line is we saw some stuff," said Mike Moses, chairman of the mission management team. "Some of it doesn't concern us. Some of it you just can't really speculate on right now. But we have the tools in front of us and the processes in front of us to go clear this vehicle for entry" at the end of the month.
At a news conference, Gerstenmaier noted that the Endeavour crew has shuttle repair kits on board. In case of irreparable damage, the astronauts could move into the space station for two to three months and await rescue by another shuttle.
