One-of-a-kind meteorite unveiled UNIVERSITY OF ALBERTA NEWS RELEASE Posted: April 22, 2006 The depths of space are much closer to home following the University of Alberta's acquisition of a meteorite that is the only one of its kind known to exist on Earth! What makes it so rare? The meteorite is 'pristine' - that is, still frozen and uncontaminated - and so provides an invaluable preserved record of material from when the solar system formed 4.57 billion years ago. The Tagish Lake Meteorite is carbonaceous chondrite and, as such, represents primitive material from which the solar system formed. The meteorite is rich in pre-solar grains - grains from other stars that were present near our solar system when it formed. The meteorite contains primitive molecules that are the building blocks of the components necessary for life. The pristine state of the meteorite makes it especially important for scientific research purposes; it presents an unprecedented opportunity to look for extraterrestrial ices. The University of Alberta, through the Department of Museums and Collections Services and the Department of Earth and Atmospheric Sciences, led a consortium of partners that, together, acquired the pristine samples for mutual research and heritage interests. These partners include the Department of Canadian Heritage, the Royal Ontario Museum, Natural Resources Canada, and the Canadian Space Agency. Dr. Christopher Herd, the Curator of the University of Alberta Meteorite Collection, will lead future research on the University's approximately 650 grams of this unique extraterrestrial rock. "What's fascinating about the Tagish Lake Meteorite is that it enables us to probe the farthest reaches of our solar system by studying material that has come to us,' noted Dr. Herd, a professor of Earth and Atmospheric Sciences at the University of Alberta. The study of the meteorite has the potential for revolutionizing our understanding of the formation of the solar system. The meteorite fell on the frozen surface of Tagish Lake, northern BC, in Canada on January 18, 2000. The University of Alberta is home to Canada's second-largest meteorite collection. Most recently, Dr. Herd has established a research program in the study of meteorites from Mars; research in meteorites in the collection and others on loan to the University continues to this day. Expertise in other areas of space research reside on campus ranging from the history of space exploration to the formation of dust devils on Mars, and spanning the humanities, engineering and the sciences. |

This 25th anniversary celebration of the first space shuttle launch took place April 12 at Space Center Houston. Speakers included Johnson Space Center Director Mike Coats, NASA Administrator Mike Griffin, Congressman Tom DeLay, Senator Kay Bailey Hutchison, STS-1 commander John Young and pilot Bob Crippen. 
Dial-up: 
During this NASA news conference on April 10, agency officials unveil the Lunar Crater Observation and Sensing Satellite, or LCROSS, that will launch piggyback with the Lunar Reconnaissance Orbiter spacecraft in October 2008. LCROSS will use the launch vehicle's spent upper stage to crash into the moon's south pole in an explosive search for water.
Daniel Andrews, the LCROSS project manager from NASA's Ames Research Center, narrates this animation depicting the mission from launch through impact on the lunar surface.
In this highly entertaining program, commander John Young and pilot Bob Crippen of the first space shuttle crew tell stories and memories from STS-1. The two respected astronauts visited Kennedy Space Center on April 6 to mark the upcoming 25th anniversary of Columbia's maiden voyage.
