On Wednesday, June 20, 2001, following a go ahead from Shuttle management, KSC workers began rolling Space Shuttle Atlantis out of the VAB at about 2:30 a.m. today. When weather officials noted the threat of lightning in the vicinity of the Launch Complex 39 area, managers returned Atlantis to the VAB as a safety precaution. Atlantis has been rescheduled for rollout to Launch Pad 39B at about 12:30 a.m. Thursday, June 21. (Reference KSC Shuttle Status 6/20/2001)

On Tuesday, June 19, 2001, Space Shuttle and International Space Station managers agreed to proceed with plans to launch Space Shuttle Atlantis no earlier than July 12. The official launch date will be announced after the Flight Readiness Review scheduled for June 28. The Terminal Countdown Demonstration Test is scheduled for June 28-29 at KSC.

On Thursday, May 31, 2001, NASA managers announced that Space Shuttle Atlantis will not launch before early July. The additional time will enable the International Space Station Program time to evaluate a problem with the Station's new robot arm. Shuttle and Station managers will reconvene in mid-June to assess a new launch date. The Flight Readiness Review has been postponed with a new date to be announced. Orbiter Atlantis rolled over to the Vehicle Assembly Building (VAB) last night, and workers are preparing to mate the orbiter to the external tank in VAB high bay 1. Once fully stacked, the Space Shuttle will remain in the VAB until a new rollout date is selected. (Reference KSC Shuttle Status 5/31/2001)

Managers announced a target launch date of no earlier than June 8 for Atlantis' next flight on mission STS-104. This shift accommodates an on orbit sun angle condition between May 18 and June 7. This so-called beta angel cut-out is an undesirable thermal condition for Shuttle/ISS docking operations. Previous launch date was no earlier than February 8, 2001.
