Chandra's director, Dr. Harvey Tananbaum, explains the significance of that early image. http://chandra.harvard.edu/resources/podcasts/ts/ts072607.html http://chandra.harvard.edu/resources/podcasts/ts/ts072607.html Thu, 26 Jul 2007 12:00:00 EST Just after midnight on July 23, 1999, the Space Shuttle Columbia launched in orbit with the heaviest payload ever carried by a shuttle.
