All going well as it seems, even the weather, before next week’s launch of the space shuttle Endeavour, with the mission of sending a Japanese laboratory to the International Space Station. The launch is set to take place on Tuesday at 2:28 a.m. EDT (0628 GMT) from the Kennedy Space Center in Florida.

After a problem occurred with the high-power amplifier on one Ultra High Frequency (UFC) radio, NASA decided to use the backup system for the March 11 flight, as it meets all the flight safety rules requirements.

“We have no other issues to report,” said NASA test director Steve Payne during the STS-123 Countdown Status Briefing. “The systems are clean, it appears it’s going to be a good day for us and Endeavour and her crew are ready to launch.”

As it appears, on the day of the launch there will be only 10 percent chance for the weather to delay the launch. In the worst scenario, the chances will not pass 20 percent, so everything looks good so far for Endeavour.

NASA will have a total of two opportunities to complete the launch, on March 11 and March 12, before it will have to make way for the Air Force Delta 2 rocket, which carries a Global Positioning System navigation satellite. The next attempt, in case the first two fail, is scheduled to take place on March 17, in the evening.

The space ship’s crew will spend 16 days in space and on the International Space Station, for the installation of the Japanese Kibo complex and attachment of a Canadian robot on the outside of the station for maintenance purposes.

Endeavour is set to return on March 26 at the Kennedy Space Center, at around 8:35 p.m. if everything goes as planned. The International Space Station has been the center of many new adjustments and missions, as new tools and international laboratories are being added.
