Astronomers have obtained the first images of an asteroid on course to make its closest approach to Earth on Tuesday, showing the space rock is lopsided.
The new images, taken with the Goldstone Solar System Radar Telescope in California's Mojave Desert, refine estimates of the asteroid's size.
Named 2007 TU24, the asteroid was estimated to span up to 2,000 feet (610 meters), but is now thought to have a diameter of about 800 feet (250 meters).

Scientists at NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, Calif., have determined that there is no possibility of an impact with Earth in the foreseeable future.
Other radar telescopes will point toward the asteroid as it makes its closest approach to Earth, 334,000 miles (537,500 kilometers), at 3:33 a.m. Eastern time Jan. 29.
For comparison, the moon is an average of 239,228 miles (385,000 kilometers) away.

RE: Fall from `Space ~0~~~~X
WASHINGTON (AP) -- A large U.S. spy satellite has lost power and propulsion and could hit the Earth in late February or March, government officials said Saturday.[/b]
[/align][align=center]Defunct Spy Satellite Falling From Orbit
A senior government official says lawmakers and other nations are being kept apprised of the situation.[/align][/align][/align][/align]The satellite, which no longer can be controlled, could contain hazardous materials, and it is unknown where on the planet it might come down, they said.
The officials spoke on condition of anonymity because the information is classified as secret.
"Appropriate government agencies are monitoring the situation," said Gordon Johndroe, a spokesman for the National Security Council.
"Numerous satellites over the years have come out of orbit and fallen harmlessly. We are looking at potential options to mitigate any possible damage this satellite may cause."
Watch why the bus-sized satellite is causing concern »He would not comment on whether it is possible for the satellite to be perhaps shot down by a missile. He said it would be inappropriate to discuss any specifics at this time.

The goal is to hit the satellite just before it enters Earth's atmosphere and blast it apart so that the hydrazine tank explodes. The smaller debris would be more likely to burn up in the atmosphere.
NASA Administrator Michael Griffin said there's nothing the military can do to make the outcome worse.

WASHINGTON (CNN) -- The U.S. military may try within days to shoot down a failed satellite using a missile launched from a Navy ship, officials announced Thursday.
A Delta II rocket lifts off in December, carrying a reconnaissance satellite that failed hours later.
[align=center][/align][align=center][/align] A Delta II rocket lifts off in December, carrying a reconnaissance satellite that failed hours later.
Gen. James Cartwright, vice chairman of the Joint Chiefs of Staff, told reporters at the Pentagon that the window to accomplish the mission could begin in three to four days, and remain open for seven to eight.
While much space trash and debris have safely crashed to Earth after burning up in the atmosphere on re-entry, authorities said what makes this 5,000-pound satellite different is the approximately 1,000 pounds of frozen toxic hydrazine propellant it carries.
Without any intervention, officials believe the satellite would come down on its own in early March.
If it came down in one piece, nearly half the spacecraft would survive re-entry and the hydrazine -- heated to a gas -- could spread a toxic cloud roughly the size of two football fields, Cartwright said.
Hydrazine is similar to chlorine or ammonia in that it affects the lungs and breathing tissue, the general said.
The option of striking the satellite with a missile launched from an Aegis cruiser was decided upon by President Bush after consultation with several government and military officials and aerospace experts, said Deputy National Security Adviser James Jeffrey.

Try?
Try to shoot it down?
TRY????????
So we can shoot missles from planes with cameras in the nose and these missles will impact the designated target but we can't hit the broadside of a barn (or spy satillite) with all the Japanese technology we have in this country???
