Space shuttle Endeavour has successfully docked with the
International Space Station (ISS) but engineers said some damage was
caused to the shuttle's heat shield during launch.
The Endeavour crew Friday positioned the shuttle alongside the ISS,
where they will install a truss that is part of station's solar
power system and will deliver supplies and equipment to the ISS
crew.
"It was a flawless rendezvous," said NASA Flight Director Matt
Abbott at a press conference in Houston, Texas. "Everything was from
the book."
Before docking at 18.02 GMT, the Endeavour performed a back flip
manoeuvre to inspect the shuttle for damage to its heat shield that
it may have sustained during take off.
The damage was about 7.5 by 7.5 cm in diameter on a tile on the
underbelly of the space craft and was most likely caused when a
piece of ice struck the tile during Wednesday's launch, according to
NASA Programme Manager John Shannon.
The spot would be examined more closely on Sunday to help decide
what repairs might be needed, Shannon said, adding that such repairs
were a new phenomenon.
"We have a rich flight history of tile damage." Shannon said. "In
the past we didn't even know we had damage and we flew back home."
Damage to the heat shield - much larger than that discovered on
Endeavour - was what led to the Columbia shuttle disaster in 2003,
in which seven astronauts were killed.
Endeavour blasted off Wednesday on its first flight into space since
that 2003 disaster.
