Stardust Snaps the Moon as it Flies By.

Mir's Gyros Have Failed But Docking Will Still Proceed
Stardust Snaps the Moon as it Flies By
15 Years After the Challenger Tragedy, What Lessons Were Learned?
MIR'S GYROS HAVE FAILED BUT DOCKING WILL STILL PROCEED
Because of a sudden power loss last week Mir's gyroscopes have failed, and Russian ground controllers haven't been able to get them working again. The gyros are necessary to keep the station aligned, so while they're not working controllers are using a collection of small thrusters to ensure the station doesn't spin out of control. Even without the gyros, the Russians still plan to dock a Progress cargo vessel later this week to transfer fuel to the station. Mir will be brought back to Earth in early March.
STARDUST SNAPS THE Moon AS IT FLIES BY
On its way to meet up with Comet Wild-2 in 2004, the Stardust probe flew by the Earth and the Moon on January 15th. This flyby gave engineers a valuable opportunity to determine how well they had cleared off the probe's cameras after they were covered with an unknown goo earlier this year. As it buzzed by, controllers used Stardust to take pictures of the Moon's north pole. Although there is still some of the unknown substance on the camera, the imaging is clear enough for the probe to successfully complete its mission.
15 YEARS AFTER THE CHALLENGER TRAGEDY, WHAT LESSONS WERE LEARNED?
A recent technical delay with the Space Shuttle Endeavour gave journalists a hook to consider what lessons were learned since the Challenger disaster 15 years ago. In 2001, controllers are willing to scrub a mission for a problem that might not even exist. But 15 years ago, many engineers felt an accident like the Challenger was not only possible, it was inevitable.
