Misja NEAR na Erosie...

The face of Eros
On 12 February this year, the Near-Earth Asteroid Rendezvous (NEAR)
Shoemaker spacecraft landed on the asteroid Eros. Three analyses of what it
saw are published in this week's Nature, revealing a miniature world of
surprising complexity, far removed from the public's view of asteroids as
featureless lumps of rock. Eros, which measures 34 x 13 x 13 kilometres, is
strewn with boulders, nearly 7,000 of which are more than 15 metres across.
Most of these resulted from an impact that formed the 7.6-kilometre-wide
'Shoemaker' crater, the asteroid's main feature, write Joseph Veverka, of
Cornell University, Ithaca, and colleagues. The asteroid also has many
mysterious 'ponds' of bluish dust. What caused these is unclear, but solar
energy may have made the particles electrically charged, causing them to
levitate out of the asteroid and settle on its surface. In an accompanying
News and Views article, Erik Asphaug of the University of California, Santa
Cruz, discusses the possible relevance of these findings for would-be
asteroid miners, or those trying to divert an asteroid from a course to hit
the Earth.
