Fewer
than 24 hours after the successful launch of Space Shuttle Endeavour,
NASA officials said its
mission was
going well despite two glitches and a strange object spotted in video of the launch.
โIt was a beautiful, awesome night launch,โ said Mike Moses, lead shuttle flight director for the STS-123 mission, noting that an on-orbit inspection of Endeavourโs heat shield progressed without any hiccups. โItโs going great, no issues to report there.โ
Led by commander Dominic Gorie, the mission of the seven-astronaut crew of Endeavour is
to deliver the first of Japanโs three-piece Kibo laboratory and Canadaโs monstrous
robot named Dextre to the international space station (ISS). Their
16-day mission will be packed with
five 6.5-hour spacewalks all dedicated to
assembly of the growing orbital outpost.
Several hours after Gorieโs crew launched into space March 11
, spacecraft communicators told Gorie that a strange object was spotted in launch video 10 seconds into the liftoff.
The object, seen as a white streak in
imagery gathered during Endeavourโs launch, originated
a distance away from the shuttleโs now-discarded 15-story external fuel tank, then disappeared. Moses said heโs not sure if the object vanishes because it slammed into the nose cap of Endeavour, or if it simply slipped behind the port-side of the orbiter.
โWe donโt know what it is yet, and weโre still looking at it,โ Moses said of the mystery object, which he does not think is an errant chunk of ice or insulating foam shed from the orange external tank. โThe imagery is very inconclusive.โ
Whatever the case, Moses said heโs confident Endeavour will be in good shape for a March 26
landing.
โFor the health of this orbiter, I can kind of put it out of my mind because [weโve scanned] the nose cap at the front end of the orbiter,โ he said.
Prior to docking with the international space station, Commander Gorie, shuttle pilot Gregory H. Johnson and mission specialist Takao Doi of Japan performed the six-hour inspection using the shuttleโs
15-meter
sensor-tipped extension boom.
Moses also noted
two problems that occurred during launch โ the failure of a heat-dissipating system and a
computer that controls firing of the orbiterโs thrusters โ are of little concern for the completion of the STS-123 mission because of redundant systems and potential fixes.
Spacewalkers Rick Linnehan and Garrett Reisman were
slated to begin the first of five planned excursions
at about 9:23 p.m. EDT
March 14, with initial assembly on Dextre. The
shuttle Endeavour arrived at the space station late
March 12.
Dextre is an on-orbit servicing robot designed to cut down on the number of dangerous spacewalks astronauts have to perform.
โItโs this giant robot with arms and โฆ wrists and hands,โ Linnehan said of the special-purpose dexterous manipulator
, as it is formally known.
Linnehanโs and Reismanโs
job was to attach each of Dextreโs
52-kilogram
hands to its respective
300-kilogram
arm during the spacewalk and to
fully assemble the massive robot arms on a mobile platform on the space stationโs Port 1 truss.
In all, the astronauts were scheduled to conduct three spacewalks to complete Dextre.
Before the astronauts partially piece Dextre together, however, they also were scheduled to
help prepare the Japanese Logistics Pressurized (JLP) module for its voyage out of Endeavourโs payload bay. The module is the first piece of Japanโs massive laboratory called Kibo, which means โHopeโ in Japanese.
Immediately after leaving the airlock, the spacewalkers will migrate to the payload bay and remove thermal covers that protected the JLP module during flight.
Bob Behnken and Leopold Eyharts, robotic arm operators and STS-123 mission specialists, will then hoist the 9.2-ton cylindrical module that will serve primarily as extra space for the Japan Aerospace Exploration Agencyโs Kibo laboratory.
โI donโt mean to insult my own payload here,โ Reisman said, โ[but] itโs really just a closet of the Japanese laboratory.โ
As the orbital closet is delivered to the top of the Harmony module, where it will remain until STS-124 astronauts deliver its
11-meter
counterpart called the Pressurized Module, Reisman said he might
be a little distracted. โWeโll be focused on our โฆ work, but out of the corner of our eye weโll see them taking this big module outside the payload bay,โ he said.
