Cause for Earth's Wobble Uncovered
NEAR Takes Closest Ever Pictures of Eros
Two New Mir Missions Announced for 2001
CAUSE FOR EARTH'S WOBBLE UNCOVERED
Scientists have known about a strange wobble in the Earth's rotation since it was discovered by Astronomer Seth Carlo Chandler back in 1891, but they've only recently uncovered what causes it. It turns out that changes in pressure at the bottom of the ocean as well as fluctuations in the atmosphere are to blame. Any stress applied to the surface of the Earth affects its spin.
NEAR TAKES CLOSEST EVER PICTURES OF EROS
A short engine burn last week brought the Near Earth asteroid Rendezvous (NEAR) spacecraft to an altitude of just 35 km - close enough to take the most detailed pictures of asteroid Eros so far. The latest images show fine detail on the asteroid's surface, including strangely-shaped boulders and minor impact craters. NEAR will spend the next 10 days at this altitude, and even get a little closer.
TWO NEW MIR MISSIONS ANNOUNCED FOR 2001
Although it's currently empty, the financial backers for the Mir spacestation have plans to fill it again in 2001. The first mission will begin when businessman Dennis Tito begins his $20 million trip to the spacestation. He and two cosmonauts will join the two cosmonauts that will already be on board. Then Tito will return with the two original cosmonauts, leaving the relief crew on board to conduct an extended mission for the second half of 2001.
