Shuttle Foam To Be Left Off Fuel Tank
Houston (UPI) Dec 16, 2005 The insulating foam on the space shuttle that broke loose during liftoff last July, will be removed from future launches, NASA officials said in Houston. William H. Gerstenmaier, director of space operations, at the National Aeronautics and Space Administration, said a large section of the foam that shielded pipes and cables on the shuttle's large external fuel tank would most likely not be used again, the New York Times reported Friday. Engineers have long assumed the area, known as the PAL ramp, needs the insulating foam to protect equipment, but wind-tunnel tests and computer models indicate the foam is no longer necessary. "The best thing to do is to just take it off," Gerstenmaier said in a telephone news conference from the Johnson Space Center in Houston. NASA engineers had been surprised when a one-pound piece of foam broke free from the area despite years of efforts to eliminate or reduce foam shedding.

The Next Shuttle Book Review
Marion IA (SPX) Dec 02, 2005Dave Ketchledge, a high powered rocketry hobbyist, has written and e-published a new book, titled The Next Shuttle, devoted entirely to the construction and flight of Shuttle prototypes, their technical problems, how they were solved, and successors of the Shuttle today. Dave is a professional Instrumentation Engineer, a former Navy nuclear reactor operator and testing engineer, and a member of both NAR and TRA. Back in the 1990s, Dave coined the term Vertical Trajectory System, or VTS to describe several active guidance systems potentially useful to amateur rocketry. |
