  • Alan Bean, Apollo Moonwalker and Artist, Dies at 86
    For Immediate Release Media Contacts: Laura Cutchens Astronaut Scholarship Foundation 407-403-5907 or 407-474-3196 [email protected] Justin Miller Astronaut Scholarship Foundation 407-403-5908 or 407-724-3002 [email protected] Alan Bean, Apollo Moonwalker and Artist, Dies at 86 HOUSTON, Texas — Apollo and Skylab astronaut Alan Bean, the fourth human to walk on the moon and an accomplished artist, has died. Bean, 86, died on Saturday, May 26, at Houston Methodist Hospital in Houston, Texas. His death followed his suddenly falling ill while on travel in Fort Wayne, Indiana two weeks before. “Alan was the strongest and kindest man I ever knew. He was the love of my life and I miss him dearly,” said Leslie Bean, Alan Bean’s wife of 40 years. “A native Texan, Alan died peacefully in Houston surrounded by those who loved him.” A test pilot in the U.S. Navy, Bean was one of 14 trainees selected by NASA for its third group of astronauts in October 1963. He flew twice into space, first as the lunar module pilot on Apollo 12, the second moon landing mission, in November 1969, and then as commander of the second crewed flight to the United States’ first space station, Skylab, in July 1973. “Alan and I have been best friends for 55 years — ever since the day we became astronauts,” said Walt Cunningham, who flew on Apollo 7. “When I became head of the Skylab Branch of the Astronaut Office, we worked together and Alan eventually commanded the second Skylab mission.” “We have never lived more than a couple of miles apart, even after we left NASA.

  • The Scientific Legacy of Apollo
    The Scientific Legacy of Apollo Ian A. Crawford, Department of Earth and Planetary Sciences, Birkbeck College, University of London ([email protected]). Article published in the December 2012 issue of the Royal Astronomical Society’s journal Astronomy and Geophysics (Vol. 53, pp. 6.24-6.28). Abstract On the 40th anniversary of the last human expedition to the Moon, I review the scientific legacy of the Apollo programme and argue that science would benefit from a human return to the Moon. Introduction This December marks 40 years since the last human beings to set foot on the Moon, Gene Cernan and Harrison “Jack” Schmitt of Apollo 17, left the lunar surface and returned safely to Earth. This anniversary alone would have justified a retrospective look at the legacy of the Apollo project, but it has been given additional poignancy by the death earlier this year of Neil Armstrong, the first man to set foot on the lunar surface with Apollo 11 in July 1969. The history of the Apollo project, and its geopolitical motivation within the context of the Cold War, is of course well documented (e.g. Chaiken 1994; Burrows 1998; Orloff and Harland 2006) and need not be repeated here. However, although the scientific legacy of Apollo has also been well-documented (e.g. Heiken et al. 1991; Wilhelms 1993; Beattie 2001), and is generally well-known within the lunar science community, I have found that it is still underappreciated by many astronomers, and even some planetary scientists who are not directly involved in lunar studies.

Our center will be a consortium composed of senior level investigators representing Indiana University, Princeton University, University of Tennessee, Pacific Northwest National Laboratory, Oak Ridge National Laboratory, Lawrence Berkeley National laboratory, University of Toronto, and the Lunar and Planetary Institute. We believe our expertise in subsurface ecosystems and our access to extraordinary analytical facilities and field sites will enable development of synergistic relationships with other biological, geological and planetary research in the NAI.
