Space Station Nearly Struck By Debris

NASA controllers attempted to fire the International Space Station’s rockets to move it out of the way of a piece of Russian space junk which was going to pass too close for comfort. Unfortunately, the computer program designed to execute the maneuver crashed the ISS for 90 minutes. Fortunately the debris missed the station by a safe margin.

Mir Will Have One Last Crew

Although they’re still planning for Mir’s fiery destruction later this year, Russian space officials have announced they’ll be sending one final crew to the doomed station. It’s still unknown how the Russians will be able to guide Mir’s 100 tonnes safely back to Earth and crash into an uninhabited area.

Cosmonauts Try to Raise Money for Mir

Desperate to keep Mir in orbit, two Russian cosmonauts have begun a grassroots effort to find funding for the doomed space station. Vitaly Sevastyanov and Gherman Titov have created the “People’s Charity Foundation” as a way for ordinary Russians to contribute to the station’s funding. They’ll need to raise $100 – $250 million to keep it up another year.

Originally slated for launch later this year, Japanese space officials have pushed back the launch of the Lunar-A spacecraft for at least 3 years. The spacecraft is designed to orbit the moon, and deploy penetrator probes into the surface. Upon tests, however, these probes were found to malfunction when they hit the ground, requiring the Japanese to redesign the system from scratch.

Electrical Problem May Have Caused IKONOS Failure

It seems that aerospace companies do nothing but post-mortems these days. Lockheed Martin believes that the IKONOS 1 rocket launched from an Athena II rocket never reached orbit because of an electrical problem, which stopped a protective cover from being ejected at the proper time. With the additional load of the cover, the rocket didn’t have enough energy to reach orbit.

WIRE Failure Caused by Power Glitch

An investigation into the failure of the Wide-Field Infrared Explorer (WIRE) satellite has concluded that a surge in a circuit led to the failure of the satellite. When the satellite was turned on, the surge caused it to prematurely blow the bolts on a sunscreen which protected a hydrogen tank. The unprotected hydrogen sublimated, spinning the satellite out of control.
