NASA gave the green light for a launch attempt Tuesday for Space Shuttle Discovery on its Return to Flight mission (STS-114). Launch is scheduled for 10:39 a.m. EDT, and it will be carried live on NASA TV.
Senior NASA managers met Sunday at Kennedy Space Center for a launch readiness meeting. Discussions focused on recent problems related to a liquid hydrogen low-level fuel sensor inside the external fuel tank, which prompted postponement of the Shuttle’s launch on July 13. Since then, engineers have been working around-the-clock on troubleshooting the sensor system issue.
During the countdown, managers will monitor for recurrence of the problem. If any new sensor-related issues occur, engineers would stop the countdown to reassess the situation.
During their 12-day mission to the International Space Station, Commander Eileen Collins and her six fellow astronauts will test new techniques and equipment designed to make Space Shuttles safer. They also will deliver supplies and make repairs to the Space Station.
