Space Shuttle Discovery is on course to land at the Kennedy Space Center this afternoon, and after a busy time in orbit, Rochester native Pam Melroy and her crew are ready to come home. During 15-days in space astronauts installed a new module, relocated and repaired damaged solar arrays and conducted four spacewalks while also transferring supplies and personnel. Once Discovery is safely on the ground, nasa personnel won't have a lot of down time as they make final preparations to move Space Shuttle Atlantis out to the pad for its launch early next month.
