Computer failure scrubs X-38 Space Station Return Vehicle test: also an eyeopening comparison of the very different CNN and Aviation Now reports on the same story

Compare the two stories below.

The First is from Aviation Now. It clearly states that there was a problem with the computers on the X-38 that caused.

CNN, on the other hand, reports the event as an electrical problem. There is not a single mention of the word, computers in the CNN report. This is either extremely sloppy reporting on CNN's part or a clear example of how the mainstream media distorts and/or overtly lies about events, especially those that may be related to y2k failures.

Space Station Return Vehicle Test Postponed To March 29

NASAs X-38 Crew Return Vehicle test was called off on Feb. 26 when a problem with the vehicles computers arose. Chris Nagy, chief engineer for the X-38 program at NASAs Dryden Flight Research Center, Edwards AFB, Calif., said the test has been rescheduled for March 29.

The problem centered on the X-38s two Input/Output (I/O) computers, which showed abnormal readings during the initial phases of the test, Nagy said. When the vehicle was examined, the glitch was traced to the I/O computers, which either went down simultaneously or in rapid succession for unknown reasons, he said.

The same computers also relay commands controlling the X-38s aerosurfaces during flight. Failure of the computers to properly send the commands could cause loss of control and conceivably loss of the prototype; therefore, the launch was postponed to determine what happened. Scheduling issues forced the lengthy delay.

The X-38 program is focused on developing a crew rescue vehicle for use on the International Space Station. In this test, the prototype vehicle is to be dropped from under the wing of a B-52 at an altitude of 39,000 ft. It will do several maneuvers during 11 seconds of free flight before deploying a parafoil and landing.

Electrical trouble scrubs X-38 test flight

EDWARDS, California (CNN) -- A prototype spacecraft designed to serve as a "lifeboat" for the International Space Station developed an unexpected electrical problem on Saturday, forcing NASA to scrub a test flight.

Known as the X-38, the low-cost vehicle is expected to become the first new U.S. manned spacecraft to fly to and from space in more than 20 years.

High winds on Friday pushed the test back a day. And on Saturday a B-52 took off carrying the X-38. The prototype was supposed to be released from 35,000 feet and land at the Dryden Flight Research Center.

But within minutes the X-38 experienced a electrical short, possibly in its flight control system, said Dryden spokesman Alan Brown. The B-52 returned to Dryden without releasing the X-38.

The problem was "totally unexpected and relatively minor," Brown said.

But since project managers "didn't understand what caused it, they were worried it might happen again" and decided not to complete the test, Brown said. The flight will most likely be rescheduled for the end of March.

One reason the flight test in California will be delayed at least several weeks is that some of the mission personnel will participate in a test of the X-38's parafoil in Yuma, Arizona, later this week, Brown said.

Last month, the X-38 team successfully flew the largest parafoil parachute ever at the U.S. Army's Yuma Proving Ground. Mission engineers released a parachute with an area almost one and half times as big as the wings of a Boeing 747 jumbo jet.

Early proposals to develop and build a crew return vehicle exceeded $2 billion. NASA estimates it can produce the X-38 prototype at one-tenth the cost, in large part by using many existing technologies and over-the-counter parts to construct the vehicle.

NASA and the European Space Agency are developing the X-38 primarily as an emergency rescue vehicle for the ISS. But space officials hope to apply the design to other purposes, such as a manned spacecraft that could be launched on the French Ariane 5 booster.
