Background Challenger was destroyed in the second minute of STS-51-L, the orbiter’s tenth mission, on January 28, 1986 at 11:38:00 a.m. EST, when an O-ring seal on its right solid rocket booster (SRB) failed. The O-rings failed to seal due to a variety of factors, including unusually cold temperatures. This failure allowed a plume of flame to leak out of the SRB and impinge on both the external fuel tank (ET) and SRB aft attachment strut. This caused both structural failure of the ET and the SRB pivoting into the orbiter and ET. The orbiter’s attitude rotated out of the…

(NASA SP-2010-4704) by Steven Dick [765 Pages, 9.11 MB] Remembering the Space Age. (NASA SP-2008-4703) by Steven Dick [482 Pages, 9.28MB] – Abstract: Fifty years ago, with the launch of Sputnik I on October 4, 1957 and the flurry of activity that followed, events were building toward what some historians now recognize as a watershed in history—the beginning of the Space Age. Like all “Ages,” however, the Space Age is not a simple, straightforward, or even secure concept.…
Background The following reports were created by Dr. J. Allen Hynek, the scientist infamous for having consulted for the U.S. Air Force’s Project Blue Book, then later devoting his life to the field of UFO research. These documents offer a rare glimpse into the life of Dr. J. Allen Hynek — away from his study into the UFO phenomenon. Document Archive John Greenewald, Jr. of The Black Vault gets Hynek papers declassified [2 pages] – This two page memo to the DTIC downgrades the restriction on 8 of Hynek’s papers. The FOIA case referenced is a letter filed by The…
