NASA has just announced that the mission managers have decided to scrub Tuesday's launch attempt .
Preliminary preparations are also under way to roll the orbiter back to the Vehicle Assembly Building, although no final decision has been made to allow for possible changes in Tropical Storm Ernesto's track. That decision is expected by midday Tuesday. NASA's lighted launch window extends to Sept. 13, but mission managers are hoping to launch by Sept. 7 to avoid a conflict with a Russian Soyuz rocket also bound for the International Space Station. Officials are talking with our Russian partners about the issue.
NASA technicians planned to carry out additional tests on Sunday to check whether space shuttle Atlantis was damaged by a lightning strike at the launch pad and the agency said the ship's launch would likely be delayed at least until Tuesday.
Managers debated overnight whether the shuttle's twin solid rocket boosters could have been affected by a huge bolt of lightning that hit the Florida launch pad Friday afternoon.
The launch of space shuttle Atlantis, scheduled for Sunday, has been delayed 24 hours because of a lightning strike and other weather concerns, NASA officials said Saturday.
Earlier, Kathy Winters, NASA’s shuttle weather officer, said there was a 40 percent chance that weather at the Kennedy Space Centre would prohibit the lift off at 4:30 p.m. Sunday.
Stormy weather and a lightning strike at the launch pad forced technicians on Friday to delay fuelling the system that will power the space shuttle during the mission. The interruption wasn't expected to affect the countdown since the fuelling had started earlier than planned. The lightning struck a wire on a tower used as lightning protection and didn't appear to cause damage.
According to officials at the U.S. space agency, NASA will attempt to launch space shuttle Atlantis on August 27 to restart construction of the half-built International Space Station.
"We set the launch date for the 27th, I think it's around 4:30 in the afternoon, so we're ready to go for that" - Bill Gerstenmaier, associate administrator for space operations.
NASA engineers are looking at a possible problem with a key antenna aboard the space shuttle Atlantis, which is set for launch later this month to the international space station.
Engineers noticed that bolts holding the KU-band antenna box inside the shuttle’s cargo bay might not be the proper type. Officials say it’s too early to know if the bolts are a problem — noting that Atlantis has flown many missions with the bolts “as-is.” The concern is that the antenna could shake loose during liftoff, a potentially dangerous situation.
The space shuttle Atlantis has been moved to the launch pad 39-B early today in preparation for an August 27th lift-off. The launch window is between August 27 and September 13.
The Shuttle Atlantis (ISS 12A) STS-115 is scheduled to launch at 20:25-20:35 GMT (4:25-4:35 p.m. EDT) on August 27th, 2006, from LC-39B, Kennedy Space Centre, Florida. The nineteenth U.S. mission to the International Space Station, will deliver and attach the next port truss segment to the station -- the Integrated Truss Structure P3/P4 and associated set of power-generating solar arrays.
