NASA called off today's planned launch of the shuttle Endeavour earlier this morning when a hydrogen leak was discovered near the Ground Umbilical Carrier Plate. The GUCP was also the location of the leak that shut down Saturday's launch attempt, so it appears that the repairs made to that system over the last few days did not quite have the desired effect.
According to NASA's website, the launch has been rescheduled for 11 July, at 7:39 pm EDT.

Apparently the launch is on hold, they hope to have the issues resolved soon and a new launch date scheduled.
