Asteroid 2008 BT18: 1 rock now seen as 2 asteroid buddies
By: William Atkins
Astronomers discovered asteroid 2008 BT18 earlier in 2008, thought it was a giant rock hurling through space near Earth, but now have found out that it is, actually, two asteroids--what astronomers call a binary asteroid.

Not everybody wants to go to Moon before going to Mars
By: William Atkins
NASA’s Constellation lunar base program is geared toward sending astronauts to the lunar surface by 2020. But, should the United States go to the Moon or, maybe, instead go to an asteroid to better prepare ourselves for the big trip to Mars?

Asteroid 2007 WD5 passes safely by Mars; 2007 TU24 does same with Earth
By: William Atkins
Going from a 3.6% chance to a zero chance of hitting Mars, Asteroid 2007 WD5 raced by the Red Planet without a collision, coming within about 13,700 miles of the planet. Also, Asteroid 2007 TU24 passed by Earth, a day earlier, on January 29, 2008, without any problems.

Comet Wild 2 looks like asteroid to NASA Stardust spacecraft
By: William Atkins
NASA’s Stardust mission to Comet Wild 2 back in 2004, in which samples were returned to Earth, are now being analyzed by astronomers. They are surprised because the comet looks more like an asteroid: calling it an asteroid-like comet.

Sandia simulation shows small near-earth objects can cause big troubles
By: William Atkins
A Sandia supercomputer has found that the space body causing the Tunguska explosion, which destroyed hundreds of thousands of acres and thousands of animals, in Siberia in 1908 was 3-4 times smaller than what first thought. Humans should pay attention to these smaller space bodies for the sake of millions of lives.
