well as the Space Shuttle. She relinquished this position on being assigned to command STS-93. After returning from that mission, she became the chief information officer at the Astronaut Office. In that role she automated the scheduling system, an initiative of the new Chief of the Astronaut Office, Charles Precourt. She then became the chief of the Space Shuttle Branch, remaining in this role until November 2000, when she left on maternity leave. On returning to work in January 2001, she became the chief of the Safety Branch, replacing Rick Husband, who left to command the STS-107 mission. In turn, Collins handed over the position to Dom Gorie when she was assigned to command STS-114 in late 2001. The STS-114 mission involved docking Atlantis with the ISS to transfer crewmen and supplies. Jim Kelly was assigned as the mission's pilot and Stephen Robinson and Japanese JAXA astronaut Soichi Noguchi were assigned as mission specialists. The mission would take Expedition 7 to the ISS and bring Expedition 6 back. Some of supplies would be transferred to the ISS from the Multi-Purpose Logistics Module, which would then be filled with experiments, equipment that was no longer required, and garbage to be returned to Earth. Three spacewalks were scheduled, to install an external stowage platform on the ISS Quest Joint Airlock and to replace a gyroscope that had failed. Collins was concerned about the proposed workload; she knew from her experience on STS-93 that a hectic schedule and pressure to get things done often resulted in mistakes. Problems discovered with the propellant feed lines on Atlantis and then on Discovery in June 2002 led to the entire Space Shuttle fleet being grounded again until October, pushing the launch date back to 6 March 2003. The fleet was then grounded again after the Space Shuttle Columbia disaster in February 2003. STS-114 now became NASA's "return to flight" mission to test safety improvements in addition to resupplying the ISS. The crew remained the same, but instead of the ISS expedition crew members, STS-114 would take three additional mission specialists to handle the greater workload: Andy Thomas to coordinate the spacewalks and Wendy Lawrence to operate the robotic arm, which was equipped with specialized cameras so that the Space Shuttle could be surveyed for damage. STS-114 was already scheduled to be the next mission flown, but it is unlikely that it would have remained so if
