Arlington National Cemetery
The Space Shuttle "Challenger" Memorial was dedicated on May 20, 1986, in memory of the crew of flight STS-51-L, who died during launch on January 28, 1986. Transcribed on the back of the stone is the text of the John Gillespie Magee, Jr. poem "High Flight", which was quoted by then President Ronald Reagan when he addressed the disaster. Although many remains were identified and returned to the families for private burial, some were not, and were laid to rest under the marker. Two crew members, Scobee and Smith, are buried in Arlington. On February 1, 2004, NASA Administrator Sean O'Keefe dedicated a similar memorial to those who died when the Shuttle "Columbia" broke apart during reentry on February 1, 2003. Astronauts Laurel Clark, David Brown and Michael Anderson, who were killed in the "Columbia" disaster, are also buried in Arlington.
Columbia (supercomputer)
It was slowly phased out as its successors at NAS, the petascale Pleiades supercomputer and the Endeavour shared-memory system, expanded to meet with NASA's growing high-end computing needs. At the time of its decommissioning in March 2013, Columbia was made up of four nodes over 40 SGI Altix 4700 racks, containing Intel Itanium 2 Montecito and Montvale processors to make up a total of 4,608 cores with a theoretical peak of 30 teraflops and total memory of 9 terabytes.
