“ Lock the doors”, remarked flight director Cain. The absence of communication and tracking data could mean only one thing. The Shuttle’s trajectory was timed to perfection. Even the radar used to track the Shuttle did not spot anything. All efforts from Houston to hail Columbia failed. Patchy communications were expected during re-entry, but not deathly silence. Then all communications from Columbia ceased abruptly. Further losses of sensors in the nose gear and main gear compounded the nervous atmosphere in mission control. Columbia could not make a landing while losing tire pressure. This was already bad news for the Shuttle. Soon, loss of tire pressure on the left side followed, with the readings again going off-scale. ![]() ![]() There was no commonality that could explain the fault and all other hydraulic system indications were good. The sensors measuring the data were all located in the aft of the Shuttle’s left wing. Telemetry indicated that hydraulic fluid temperatures had suddenly gone off-scale low. But nine minutes after entry interface into the Earth’s atmosphere, the ground team encountered the first hint of abnormality. Entry Flight Director LeRoy Cain gave Shuttle commander Rick Husband the go-ahead to initiate deorbit and reentry procedures. Inside mission control, engineers performed all the last minute checks. More than two decades later, STS-107 was Columbia’s 28 th mission. Its inaugural flight was on 25 th March 1981. The Shuttle that Never Came HomeĬolumbia was the first fully operational orbiter of the Space Shuttle Program. They were relaxed and jovial as the Shuttle re-entered the atmosphere, even shooting a video of what – no one realized – were their last moments. Anderson, Payload Specialist Ilan Ramon, and Mission Specialists David McDowell Brown, Kalpana “KC” Chawla, and Laurel Blair Salton Clark, had conducted microgravity research and completed experiments on commercial payloads on the debuting SPACEHAB Research Double Module. Captain Rick Douglas Husband, Pilot William “Willie” Cameron McCool, Payload Commander Michael P. The seven-member crew of STS-107 was preparing to come home after a successful 15-day mission. ![]() Nothing unusual was anticipated that day at NASA. They only numbered a couple of hundred, compared to the thousands who had gathered to watch STS-1 land. Spectators had gathered to watch Space Shuttle Columbia make what was considered another routine landing. It was an ordinary morning at the Kennedy Space Center in Cape Canaveral, Florida. A Successful 15-Day Missionįebruary 01, 2003. The lessons learned remain as relevant today as they were in 2003, if only we can keep them alive and continue to learn from this modern tragedy. By reading this introduction, and the articles accessible from the sidebar, you will learn all the facts that led to this tragedy, its technical and organizational causes, its consequences on NASA and future human spaceflight programs, the lessons learned, and the precious testimony of people directly involved in the event. This section of Space Safety Magazine is dedicated to the Columbia disaster. Its impact on US human spaceflight program, and the resulting decision to discontinue the Space Shuttle Program, was so dramatic that to this date NASA has not recovered an autonomous human access to space. The Columbia Disaster is one of the most tragic events in spaceflight history.
