Einstein Observatory
Einstein Observatory (HEAO-2) was the first fully imaging X-ray telescope put into space and the second of NASA's three High Energy Astrophysical Observatories. Named HEAO B before launch, the observatory's name was changed to honor Albert Einstein upon its successfully attaining orbit.〔(【引用サイトリンク】url=http://www.cfa.harvard.edu/hea/hm/heaob.html )〕 〔(【引用サイトリンク】url=http://www.britannica.com/EBchecked/topic/181406/Einstein-Observatory )〕 ==Launch== The Einstein Observatory, HEAO-2, was launched on November 13, 1978, from Cape Canaveral, Florida, on an Atlas-Centaur SLV-3D booster rocket into a near-circular orbit with an initial altitude slightly above 500 km. Its orbital inclination orbit was 23.5 degrees. The Einstein Observatory satellite re-entered the Earth's atmosphere and burned up on March 25, 1982.〔(【引用サイトリンク】url=http://ecuip.lib.uchicago.edu/multiwavelength-astronomy/x-ray/impact/08.html )〕
