Right this moment within the historical past of astronomy, Columbia takes off on its ill-fated remaining mission.

On Jan. 16, 2003, House Shuttle Columbia launched on its twenty eighth mission, STS-107. NASA had 5 extra house shuttle missions deliberate for 2003, however STS-107 was the one one targeted on scientific analysis; the others have been targeted on persevering with enlargement of the Worldwide House Station. The astronauts – Individuals Rick Husband, Willie McCool, Michael Anderson, David Brown, Laurel Clark, and Kalpana Chawla, and Ilan Ramon of Israel – accomplished an formidable and productive mission. The group performed practically 80 experiments, starting from combustion in microgravity to enhancing the effectivity of anticancer medication, throughout their 16 days in orbit.
Nonetheless, whereas they have been in orbit, NASA’s post-launch evaluation revealed {that a} piece of froth insulation had damaged off the exterior tank throughout liftoff, impacting the insulating tiles on the underside of Columbia’s left wing. It was unclear the quantity of injury it had prompted, and comparable “foam-shedding” occasions had occurred throughout different house shuttle launches. NASA administration concluded the strike posed no actual hazard – or, if it did, there could be nothing the astronauts might do to treatment it whereas in house.
Because the shuttle reentered the environment on Feb. 1, the outlet the influence had prompted allowed superheated air to breach the wing, melting its aluminum construction and in the end destroying it. The remainder of Columbia disintegrated, breaking up at an altitude of 39 miles (63 kilometers) over northeast Texas. All seven astronauts have been killed within the catastrophe. NASA’s accident investigation board report analyzed not solely the bodily faults, however the organizational causes rooted within the historical past and tradition of the house shuttle program – together with constraints on assets, lax security practices, poor communication, and fluctuating priorities. The next yr, President George W. Bush introduced that the house shuttle program could be retired by 2010.
