NASAs NEOWISE Completes Scan for Asteroids and Comets

NASAs NEOWISE mission has completed its survey of small bodies, asteroids and comets, in our solar system. The missions discoveries of previously unknown objects include 20 comets, more than 33,000 asteroids in the main belt between Mars and Jupiter, and 134 near-Earth objects (NEOs). The NEOs are asteroids and comets with orbits that come within 45 million kilometers (28 million miles) of Earths path around the sun.

NASA Comet Hunter Spots Its Valentine

NASAs Stardust spacecraft has downlinked its first images of comet Tempel 1, the target of a flyby planned for Valentines 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 comets nucleus.

A Valentines Day Return to Comet Tempel 1

On February 14, 2011, NASAs Stardust-NExT (New Exploration of Tempel 1) mission will encounter Comet Tempel 1, providing a unique opportunity to measure the dust properties of two separate comets (Wild 2 and Tempel 1) with the same instrument for accurate data comparison. The encounter will also provide a comparison between two observations of a single comet, Tempel 1, taken before and after a single orbital pass around the sun.
