NASA announces green aircraft challenge

Washington, August 2 (ANI): The NASA Innovative Partnerships Program and the Comparative Aircraft Flight Efficiency (CAFE) Foundation have announced the Green Flight Challenge, which is a flight efficiency competition for aircraft that can average at least 100 mph on a 200-mile flight while achieving greater than 200 passenger miles per gallon. The prize for the aircraft with the best performance is 1.5 million dollars. The competition is scheduled for July 2011 at the Charles M. Schulz Sonoma County Airport in Santa Rosa, California. A variety of innovative experimental aircraft using electrical, solar, bio-fuel or hybrid propulsion are expected to enter. Several major universities and aircraft builders have expressed their intention to enter teams in the challenge. To win, teams must use cutting-edge technologies in mechanical and electrical engineering, structures, aerodynamics and thermodynamics. As a national showcase of “green” technology, the challenge is expected to help advanc...

NASA: Despite run of tough luck, shuttle lands safely

Computerworld - After a grueling and technically intensive 16-day mission in space, the seven-person crew of the space shuttle Endeavour safely touched down at Kennedy Space Center in Florida this morning. The shuttle landed as scheduled at 10:48 a.m. ET. It was a picture-perfect landing for a shuttle that had a tough time getting off the ground due to a gaseous hydrogen leak that scuttled two scheduled launches and bad weather that derailed three other attempts. The shuttle finally blasted off on July 15 - its sixth launch attempt. Yesterday, mission control specialists found that one of Endeavour's forward thrusters, which control altitude and speed upon re-entry, failed during a test of control systems. As shown today, NASA had reported that the shuttle could land safely without the thruster. Returning from orbit, the shuttle and its crew left behind a new porch for the Japanese laboratory on the International Space Station, new batteries installed to store power collected from...

This week in space history: Vikings explore, photograph Mars

Viking 2 entered Mars orbit on Aug. 7, 1976, and set about separating fact from fiction surrounding the red planet. In 1906, "Mars and its Mystery" (Little, Brown and Co.) theorized that a "large, irregular, dark region" contained "bodies of waters, or seas. Š From remote times it has been taken for granted by the best of minds that other worlds besides ours sustain life." Wernher von Braun, the German scientist who developed the Saturn V that launched Americans to the moon, and Willy Ley discussed long-held theories in "The Exploration of Mars," (The Viking Press/1956). They wrote: "This was the picture of Mars at mid-century: a small planet of which three-quarters is cold desert, with the rest covered with a sort of plant life that our biological knowledge cannot quite encompass." In the mid-1890s, astronomer Percival Lowell was lecturing on Martian features he called canals, Mark Littman stated in "Planets Beyond" (Wiley Sc...
