Astronauts at work\u003cbr/\u003eNASA conducted a swift series of tests on the ground on Monday to determine whether spacewalking astronauts need to fix a deep gouge in Endeavour's belly for re-entry, and assembled a special team to weigh the three repair options.\u003cbr/\u003eThe gouge is relatively small: 3.5 inches (9 centimetres) by 2 inches (5 centimetres), but part of it penetrates through the protective thermal tiles, leaving just a thin layer of coated felt over the space shuttle's aluminium frame to keep out the more than 2,000-degree (1,100-Celsius) heat of re-entry. \u003cbr/\u003eThe exposed area is 1 inch (2.5 centimetre) long and less than a quarter-inch (0.6 centimetres) wide.\u003cbr/\u003eMission managers expect to decide by Wednesday whether astronauts should go out and patch the gouge. \u003cbr/\u003eThe damage is benign enough for Endeavour to fly safely home; it's more a matter of avoiding extensive post-flight repairs to any possible structural damage, said John Shannon, chairman of the mission management team.\u003cbr/\u003e\"This is not a catastrophic loss of orbiter case at all. This is a case where you want to do the prudent thing for the vehicle,\" Shannon told reporters Monday evening. \u003cbr/\u003eNASA has never attempted this type of repair on an orbiting shuttle, and two of the three remedies, all developed following Columbia's catastrophic re-entry - are untested in space. \u003cbr/\u003eEngineers are uncertain whether it was foam insulation that came off Endeavour's external fuel tank and struck the shuttle at lift-off, as was the case for Columbia four years ago, or whether the debris was ice or a combination of materials, Shannon said.\u003cbr/\u003eDespite extensive redesigning of the shuttle fuel tank that has already cost NASA a few hundred million (m) dollars, foam has repeatedly fallen off the tank during launch, although nothing nearly as big as the piece that crippled Columbia.\u003cbr/\u003eDepending on how NASA addresses the latest problem, space shuttle flights could possibly come to a temporary halt, stalling construction at the international space station once more. \u003cbr/\u003eFoam problems have caused two lengthy hold-downs.\u003cbr/\u003eTo patch the gouge, spacewalking astronauts would have to perch on the end of the shuttle's 100-foot (30.5-meter) robotic arm and extension boom, be manoeuvred under the spacecraft, and either apply black paint, screw on a protective plate or squirt in goo.\u003cbr/\u003eThe black coating, intended to help dissipate heat, was tested on a previous shuttle flight. \u003cbr/\u003eThe two other repair methods have been tested in vacuum chambers on Earth, but never in space.\u003cbr/\u003eShannon said the fact that the space shuttles are slated to retire in 2010, and the space station needs to be completed by then, did not enter the discussions.\u003cbr/\u003eA six-and-a-half-hour spacewalk by two of Endeavour's astronauts on Monday, meanwhile, was comparatively routine.\u003cbr/\u003eAstronauts Rich Mastracchio and Dave Williams ventured outside for the second time in three days, removing a 600-plus-pound (272-kilogram) gyroscope from the space station's exterior that failed last October. \u003cbr/\u003eThey installed a new one in its place that was carried up aboard Endeavour. \u003cbr/\u003eThe space station has four gyroscopes to keep it steady and pointed in the right direction.\u003cbr/\u003eEven before Endeavour's lift-off, NASA was planning a third spacewalk for Wednesday and a fourth for Friday to carry out more space station work. \u003cbr/\u003eAny shuttle repairs, if ordered, would take place on one of those two outings. \u003cbr/\u003eThe shuttle isn't due to leave the station until next Monday; landing is set for 22 August.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv
