[Geology2] Space Probe Passes Asteroid Lutetia

Space Probe Passes Asteroid Lutetia

Europe's Rosetta space probe has flown past the Asteroid Lutetia,
returning a stream of scientific data for analysis. The rock--some 120km
(75 miles) in its longest dimension--is the biggest asteroid yet visited
by a satellite.

Pictures showed Lutetia to be quite irregular in shape, its surface
marked
by a number of wide impact craters and even some intriguing grooves.
Rosetta's encounter with the asteroid occurred some 454 million km from
Earth, beyond the orbit of Mars.

"It's a new world discovered by Rosetta and it will keep scientists busy
for years," said Holger Sierks, the principal investigator on the Osiris
camera system which acquired the images on this page. "The pictures are
majestic; they take my breath away," Professor David Southwood, the
European Space Agency's director of science, told BBC News.
