X-38 Passes 1st Flight Test
Washington, DC March 13, 1998 - 
Washington, DC March 13, 1998 - Dropping down from a sun-washed sky over the Mojave Desert in California, the X-38 test vehicle landed on Edwards Dry Lake Thursday morning after its first flight test. NASA space officials declared the test a success, opening the way to some 20 additional flights in which a series of three scale models of what will eventually be a piloted rescue craft for the International Space Station will be verified.In Thursday's test, a model of the X-38 was carried aloft by a B-52 bomber, the same carrier airplane that once hauled the X-15 research rocketship in the 1950's and 1960's. At 8:30am PST, the wingless craft, based on a U.S. Air Force spacecraft design more than 25 years old, was released for descent to the desert floor. Within four seconds after separation, the X-38 deployed a special kind of steerable parachute called a parafoil, or parasail. The chute alllows ground controllers to direct the craft to different landing sites. The sail was successfully deployed, but during the glide back down to earth a tear developed in the chute that is now under investigation. The damage did not effect the landing of the craft, but space officials want to better understand what caused the tear before sending the X-38 prototype up again. Following a series of tests during the next two years, a larger full scale version of the vehicle will be launched in the payload bay of a Space Shuttle and placed adrift in orbit. The unmanned craft will then be brought back to a controlled landing in a full test of its ultimate mission. NASA and the space station's international partners will keep X-38 vehicles docked at the station for immediate emergency escape should troubles arise. Astronauts will be able to board the craft and ride it back to earth without need for controls - that function will be performed by "pilots" on the ground. The X-38 will become operational on the station by 2003, if the series of tests that started Thursday prove the design.

Satellite Launch To Boost DTH In India
Calcutta, India (SPX) Dec 28, 2005The successful launch Thursday of India's heaviest satellite from spaceport of Kourou in French Guyana may have boosted the country's space research efforts to yet another level, but it has also lifted the spirits of at least three Direct-To-Home televisions broadcasters, one of which has been waiting for years to launch its services in India. |
