Lesson Plans Astronomy Lessons (NASA Science) Provides lessons on Mars, the sun, meteors, asteroids, comets, and more. 8-00 News -01-12-06 Stardust Mission to Return with Comet Dust (TeachersFirst.com) "NASA's Stardust mission return capsule will land Sunday, Jan. 15, at approximately 2:12 a.m. Pacific time (3:12 a.m. Mountain time) on the Utah Test and Training Range. Stardust is completing a 2.88 billion mile round-trip odyssey to capture and return cometary and interstellar dust particles to Earth." 01-06 -01-15-05 Spacecraft Arrives on Earth With Comet Sample (Bloomberg.com) "A NASA capsule carrying pieces of a comet landed safely at a U.S. Air Force testing range in the Utah desert this morning after a two-year journey aboard the agency's Stardust spacecraft." 01-06 -02-01-06 Comet Discoveries (ABC News) "The Deep Impact space probe found the first evidence that comets have ice on their dusty surfaces, raising the possibility that comets may have delivered life-giving water to a primeval Earth, NASA scientists said Thursday." "Scientists long ago concluded that comets are frozen, dusty remnants from the formation of our solar system 4.6 billion years ago. Some have theorized that comets smashing into the early Earth delivered primitive organic compounds and water that helped give rise to life." 02-06 -02-20-06 Comet Dust Sparks Scientific Interest (MSNBC News) "Scientists say comets represent the cold leftovers from the solar system's beginnings, 4.5 billion years ago. The Stardust samples confirm that the material thrown off by Comet Wild 2 has not undergone chemical change for billions of years, Brownlee said: 'It's never been hot.' " 02-06 -06-27-05 NASA: Possible Fireworks on the Fourth (CBS News) "NASA hopes to shoot off its own celestial sparks in an audacious mission that will blast a stadium-sized hole in a comet half the size of Manhattan. It would give astronomers their first peek at the inside of one of these heavenly bodies." 6-05 -07-04-05 NASA Strikes Comet (CNN News) "A NASA space probe slammed into a comet early Monday, capping a six-month mission that researchers hope will give them new clues about the birth of our solar system." 7-05 -07-04-05 NASA Strikes Comet (International Herald Tribune) "On Sunday night, NASA fired a 3-foot-wide, 820-pound copper barrel directly into the path of a 9-mile-long, potato-shaped comet by the name of Tempel 1. The two successfully collided at 23,000 mph while a mother craft photographed the action from a safe distance and sent the pictures home to us." "Beneath the dirty ice crust of a comet like Tempel 1 is material that has been in deep-freeze since the birth of our solar system. Mixed into this timeless frozen treat are organic molecules like those that seeded the young Earth with raw materials for making life. That ice may hold some buried chapters of the story of our origin." 7-05 Papers Comet Hunter - Countour (Contour.org) Provides news about Countour, an unmanned spacecraft or probe that is designed to study several comets. 8-02 Comet Hyakutake Comets (Hamilton) Includes pictures, articles, and links. Comets (KidsAstronomy.com) Provides a picture and information on comets. 11-00. First Close-up Picture of a Comet (Fox News) "NASA said Saturday it has captured dozens of close-up images of a distant comet that show the frozen ball of rock and ice spewing jets of dust and gas into space." "The Stardust spacecraft...took 72 images of the dark nucleus of comet Wild 2 during a derring-do flyby Friday that occurred 242 million miles from Earth." 1-04 Questions About Comets (ASK and Astronomer for Kids) Provides questions and answers for kids and adults. 01-06 Projects Comet Properties (University of California) Provides activities to study the properties of comets. 3-01
