McLaughlin’s depth apparently once allowed underground water, which otherwise would have stayed hidden, to flow into the crater’s interior. (more…)
NASA Comet Hunter Spots Its Valentine
NASA’s Stardust spacecraft has downlinked its first images of comet Tempel 1, the target of a flyby planned for Valentine’s Day, Feb. 14. The images were taken on Jan. 18 and 19 from a distance of 26.3 million kilometers (16.3 million miles), and 25.4 million kilometers (15.8 million miles) respectively. On Feb. 14, Stardust will fly within about 200 kilometers (124 miles) of the comet’s nucleus. (more…)
