The Space Shuttle Columbia exploded during reentry on February 1, 2003, killing all seven crewmembers.
A hard drive was recovered from the wreckage, that hard drive was part of an experiment to study how xeon gas flows in microgravity.
Amazingly 99% of the data of the hard drive was able to be recovered and now, over 5 years after the explosion, the results of that experiment has been published in the journal Physics Review E.
RIP Colonel Rick Husband, Commander William McCool, Lt. Colonel Michael Anderson, Colonel Ilan Ramon, Kalpana Chawla, Captain David Brown, and Captain Laurel Clark.
