Kennedy announced the ambitious goal of sending an American safely to the Moon before the end of the decade. This challenge guided the work of NASA and accelerated technology development through 17 Apollo Missions that took place between the years of 1967 and 1972. The President’s goal was achieved on July 20, 1969, when Apollo 11 commander Neil Armstrong stepped off the Lunar Module's ladder and onto the Moon's surface. This image shows the launch of Apollo 7 in 1968, the first Apollo mission to carry a crew into space. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/6870605/6870605.dc.xml Tue, 01 Oct 1968 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/DHJRPPeru2011/DHJRPPeru2011.dc.xml Dieter Hartmann with his wife in Peru on one of their many travels. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/DHJRPPeru2011/DHJRPPeru2011.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/DieterHartmann1060/DieterHartmann1060.dc.xml Dieter Hartmann stands next to his mother on his first day of school holding an Easter cone full of candy. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/DieterHartmann1060/DieterHartmann1060.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/New_Array/New_Array.dc.xml VERITAS (Very Energetic Radiation Imaging Telescope Array System) is a system of four ground-based telescopes focused on gamma-ray science. Since gamma-rays cannot penetrate the atmosphere, the telescopes are detecting the particles created when gamma-ray photons collide with the atmosphere. Optical telescopes can then image the display the secondary particles make when passing through the atmosphere. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/New_Array/New_Array.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/ernestrutherford/ernestrutherford.dc.xml Ernest Rutherford sitting in his lab (right) with his assistant, Hans Geiger.
