At 7:42 a.m. EDT, Discovery is scheduled to undock from the ISS to initiate the return home of the STS-124 crew, having arrived at the ISS on June 2nd to deliver the Japanese Pressurized Module (JPM), the second component of the Kibo lab. Three spacewalks were performed during the mission. Discovery is scheduled to land at Kennedy Space Center in Florida on Saturday.
Later on Wednesday, with a launch window extending from 11:45 a.m. to 1:40 p.m. EDT, NASA’s GLAST spacecraft is slated to launch aboard a United Launch Alliance (ULA) Delta II rocket. The mobile service tower will be retracted from around the Delta II at about 2:00 a.m. The liquid oxygen loading, which initiates the launch countdown’s final phase, will start at 10:15 a.m. The hypergolic propellants were loaded into the rocket’s second stage over this past weekend.
