Did Something Hit Shuttle on Launch?

March 12, 2008 — -- NASA late today showed pictures of a small white object that may have hit the Space Shuttle Endeavour nine seconds after liftoff Tuesday -- but cautioned that it's far too early to tell just what the object is, or whether it's a cause for worry.

"In the video it kind of looks to some folks like there might have been an impact there; what I would tell you is it's a little bit of an optical illusion," said LeRoy Cain, the Launch Integration Manager, from the mission control center in Houston.

He said they would know more after Endeavour docks with the International Space Station. Shortly before docking, the station crew takes hundreds of high-resolution still pictures of the shuttle's nose and belly. They are later transmitted to Houston for study.

But was it a bird? A piece of ice? A piece of foam insulation from the shuttle's external fuel tank? No saying.

NASA flight director Mike Moses says says the good news is that the shuttle isn't going fast enough, ten seconds into the launch, for a debris strike to be a problem.

"I can't even begin to speculate on what it might be. We will let the experts figure it out and do a trajectory analysis to see where it came from," Moses said.

"We're at step two of, oh, a hundred" in trying to analyze it, said Cain. There were other small pieces of debris that came off the shuttle later in the climb to orbit, he said, adding that video of them would be routinely analyzed.

"We don't know if they impacted the vehicle, we don't know what they were, we don't really have enough data yet to say much more than that."

The astronauts spent their first full day in space using the orbital boom attached to the space shuttle's robotic arm to examine Endeavour inch by inch to see whether any signs of damage could be detected on the orbiter's fragile heat shield. Nothing immediately popped out at anyone during the scan, according to Moses.

This mission, designated STS-123, is one of a dozen that remain on NASA's shuttle manifest. All remaining shuttle flights, except for one to repair the Hubble Space Telescope, are dedicated to finishing construction of the space station.

Inside Endeavour's cargo bay are parts of a large laboratory called Kibo, built by the Japanese space agency. Japanese astronaut Takao Doi, who flew on a shuttle mission in 1997, is on board to oversee the assembly of the Kibo lab.

In addition, Endeavour's crew will install a Canadian-made, two-armed robot nicknamed Dextre that can move around to different parts of the space station.
