Go for Return to Flight launch today
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.
