The shuttle launch scheduled for last Saturday, June 13th, was scrubbed at the last minute because of a bad seal causing a dangerous hydrogen leak on the external fuel tanks.
The launch of STS-127 Endeavor will be delayed until the problem can be corrected. The next available launch window is June 17.
In addition to planned mission experiments, the Endeavor crew will be in orbit for 16 days to deliver spare parts and to support the installation of a lab module, Kibo, for Japan.
