That's big news not just because such an object had never been spotted before, but also because a Trojan could make such an easy and nifty place for astronauts to visit." 08-11 Asteroid - Near-Collision With Earth (CNN) Provides information on the mile wide asteroid 1997 XF11, which is expected to pass 30,000 miles from the earth in 2028. 11-99 Asteroid Exploration (JHUAPL) Provides information about the Near Earth Asteroid Rendevous (NEAR) Mission to orbit the asteroid Eros 433 in 1999. Asteroid NT7 Unlikely to Hit Earth (CNN News) "The asteroid, dubbed 2002 NT7, is travelling at 28 kilometres per second and there is a chance, initial calculations indicate, that it could hit our planet on February 1, 2019." "However, scientists said on Wednesday that the calculations are preliminary and the risk to the planet was low." 7-02 Asteroid Reports to Prevent an Extinction Level Event (National Geographic) "The Minor Planet Center, a clearing house for asteroid observations, receives up to 15,000 new sightings a day from the LINEAR telescopes alone." "The Center is part of a (U.S.) 3.5-million dollar-a-year NASA program, called Spaceguard, that locates asteroids in Earth's neighborhood. This program focuses on the estimated 1,200 to 1,500 larger asteroids in our area that are over 1 kilometer (0.6 mile) wide and could be potential planet killers, like the one that probably killed the dinosaurs some 65 million years ago." Asteroids (Hamilton) Includes articles and pictures of asteroids. Astronomy - Mission to Visit an Asteroid (CNN) Summarizes the plan by Japan to land on an asteroid and then have the spacecraft return to earth with a sample. Visitors sometimes misspell as astroid or astroide. 6-02 Averting an Asteroid Strike (Christian Science Monitor) "Scientists and engineers who have studied the problem of deflecting a dangerous asteroid believe the technical issues are difficult but solvable. The challenge now is figuring out the legal issues of who takes action on behalf of humankind and of what their responsibilities and liabilities will be." 05-09 Chicxulub Crater (Space.com) "When a giant space rock slammed into Earth 65 million years ago near the present-day village of Chicxulub on the Yucatan Peninsula, not only did it wipe out a lot of dinosaurs, it left behind a huge crater and, inside that pock, an even bigger mystery." Computer Model: Microbes Probably Survived Asteroid Bombardment (NASA) "The study focused on a particularly cataclysmic occurrence known as the Late Heavy Bombardment, or LHB. This event occurred approximately 3.9 billion years ago and lasted 20 to 200 million years. In a letter published in the May 21 issue of Nature magazine titled 'Microbial Habitability of the Hadean Earth during the Late Heavy Bombardment,' Oleg Abramov and Stephen J. Mojzsis, astrobiologists at the University of Colorado's Department of Geological Sciences, report on the results of a computer modeling project designed to study the heating of Earth by the bombardment." "Results from their project show that while the Late Heavy Bombardment might have generated enough heat to sterilize Earth's surface, microbial life in subsurface and underwater environments almost certainly would have survived." 05-09 Extinction Level Event (National Geographic) "Scientists studying the fallout from a huge asteroid that crashed into Earth 65 million years ago have gained better understanding of the event that most likely took out the dinosaurs and much other life on the planet." "The asteroid that created the Chicxulub (pronounced CHEEK-shoo-loob) crater, located on the Yucatán Peninsula of Mexico, was probably more than 6 miles (10 kilometers) wide, researchers estimate. The resulting crater was 110 to 125 miles (180 to 200 kilometers) wide and very deep. Today it is buried under several miles of limestone and is mostly underwater." Questions About Asteroids (ASK and Astronomer for Kids) Provides questions and answers for kids and adults. Visitors sometimes misspell as astroids, asteroides, or astroides. 01-06 Spacecraft Orbits Asteroid (Time.com) "The fact is, however, Vesta is the second largest object in our solar system's asteroid belt — and one of the oldest objects in the solar system as a whole — and Dawn is one of the coolest little spacecraft NASA has ever built. Together they could yield important clues to the origins of the sun and the planets, not to mention helping NASA engineers demonstrate their increasingly sophisticated cosmic-flying skills." 07-11 Spacecraft to Bring Back Sample from Asteroid (SpaceDaily.com) "If all goes well, Hayabusa will be the first spacecraft to bring home raw material from an asteroid, part of the primeval rubble left over from the making of the Solar System." 9-05 Projects Asteroid Collisions (Hamilton) Simulate an asteroid collision with the earth or another planet.. Asteroids (NASA - Jet Propulsion Lab) Provides basic information about asteroids that orbit the sun. Also provides directions on making an asteroid-like object out of potatoes. 3-00
