First stage of NASA’s ‘space elevator’ contest won

By / November 6, 2009

LaserMotive‘s photovoltaic-powered machine became the first in the three-year history of NASA’s space elevator contest to climb a 2,953-foot-long ribbon, securing a prize of $900,000. The competition saw teams use laser-powered robots they designed and built to climb a 1 kilometer-long cable suspended vertically from a hovering helicopter. LaserMotive fell short of the $2 million…

Inflatable ceramic heat shield a success

By / September 3, 2009

An inflatable heat shield was successfully tested, demonstrating for the first time that light, flexible devices could be used to protect a spacecraft as it enters the atmosphere at hypersonic speeds. The outside of the shield is made of several layers of 3M’s Nextel heat-resistant fabric woven from thin strands of ceramic. This covers several…

Artist’s rendering of Stardust’s aerogel packs. Credit: NASA NASA reported Monday that the aerogel grid that was carried by the agency’s Stardust spacecraft captured an amino acid, a finding that suggests that some of the building blocks of life may be present in much of the universe. The amino acid is glycine, the smallest of…

Would 441 pounds satisfy your sapphire craving?

By / July 11, 2009

Rubicon Technology claims it has successfully grown the world’s largest Al2O3 crystal, a boule that weighs in at 200 kg (441 lb). The company says it plans to use the material to form “high quality large-size optical windows and next-generation wafer products with dimensions over 12 in.” This is quite a leap for Rubicon. Normally,…

Proposal for new space heat shield

By / June 22, 2009

As NASA and other space agencies send space vehicles on missions that bring them closer and closer to the sun, one problem is finding improved heat shields. Recently, a group from Johns Hopkins University announced it has some innovations to offer for near-solar environments, using a shield with an alumina optical surface. Their research is…
