Launch and mission officials gathered this morning for the OSIRIS-REx Flight Readiness Review and concluded that there are no issues or concerns that would preclude continuing to target launch next Thursday, Sept. 8. Liftoff aboard a United Launch Alliance Atlas V rocket is planned for 7:05 p.m. EDT from Space Launch Complex 41 on Florida’s Cape Canaveral Air Force Station.
The Atlas V, including the payload fairing containing the OSIRIS-REx spacecraft, is in place at the pad, where vehicle closeouts have started. The spacecraft on-pad functional test will be completed today. A launch countdown dress rehearsal is set for Friday afternoon.
The Launch Readiness Review planned for Tuesday, Sept. 6 will be the final prelaunch readiness check before teams proceed with the countdown.
