A Two-toned Crater on Asteroid Eros
Explanation: What lies beneath the surface of asteroid Eros? This image taken two weeks ago by the robot NEAR spacecraft orbiting the dark asteroid shows a kilometer-wide crater where some type of light material lies beneath some of the darker surface regolith . This light substance, seen on other photographs , may be relatively fresh material not yet well exposed to a darkening solar wind and micro meteorite impacts. As fuel wanes, NASA plans to end the NEAR spacecraft mission on February 12 with a spectacular controlled descent to the asteroid's surface . Although not designed to survive a landing, it is hoped that NEAR will be able to record and relay high-resolution pictures on its way down.
