Mars Tribute Marks Memories of Shepard’s Flight
The team exploring Mars via NASA’s Opportunity rover for the past seven years has informally named a Martian crater for the Mercury spacecraft that astronaut Alan Shepard christened Freedom 7. On May 5, 1961, Shepard piloted Freedom 7 in America’s first human spaceflight. The team is using Opportunity this week… Read more“Mars Tribute Marks Memories of Shepard’s Flight”
NASA’s Gravity Probe B Confirms Two Einstein Space-Time Theories
NASA’s Gravity Probe B (GP-B) mission has confirmed two key predictions derived from Albert Einstein’s general theory of relativity, which the spacecraft was designed to test. The experiment, launched in 2004, used four ultra-precise gyroscopes to measure the hypothesized geodetic effect, the warping of space and time around a gravitational… Read more“NASA’s Gravity Probe B Confirms Two Einstein Space-Time Theories”
STS-134 Launch Scrubbed; Progress Docks to Station
Shuttle launch director Mike Leinbach stated that Endeavour’s launch will be no earlier than Monday at 2:33 p.m. EDT. Engineers need that time to troubleshoot an issue that resulted in today’s launch scrub. During today’s countdown, engineers detected a failure in one of two heater circuits associated with Auxiliary Power… Read more“STS-134 Launch Scrubbed; Progress Docks to Station”
NASA Technology Looks Inside Japan’s Nuclear Reactor
Design techniques honed at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., for Mars rovers were used to create the rover currently examining the inside of Japan’s nuclear reactors, in areas not yet deemed safe for human crews. The iRobot PackBot employs technologies used previously in the design of “Rocky-7,”… Read more“NASA Technology Looks Inside Japan’s Nuclear Reactor”
