NASA tests game changing composite cryogenic fuel tank

Posted July 2, 2013 by

NASA recently completed a major space technology development milestone by successfully testing a pressurized, large cryogenic propellant tank made of composite materials. The composite tank will enable the next generation of rockets and spacecraft needed for space exploration. Cryogenic propellants are gasses chilled to subfreezing temperatures and condensed to form highly combustible liquids, providing high-energy…

NASA’s Fermi makes first gamma-ray study of a gravitational lens

Posted January 6, 2014 by

An international team of astronomers, using NASA’s Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source. This accomplishment opens new avenues for research, including…
