Latest Asteroids Stories
While disaster movies are made about the looming threat of asteroids colliding with the earth, scientists are studying the space rocks for their mineral potential. Now scientists at the University of Strathclyde in the UK have identified a new category of asteroid they deem easy to capture.
NASA Deputy Administrator Lori Garver announced this week that the agency has received more than 400 responses to its request for information on its Asteroid Initiative.
NASA is looking for asteroids, and is seeking help from citizen scientists to locate the dangerous space rocks and reduce the potential threats they may pose to human populations.
Using the orbiting Wide-field Infrared Survey Explorer (WISE), NASA scientists have been able to identify and categorize 28 new asteroid families found in the main belt between Mars and Jupiter.
Asteroids and other objects in our solar system collide often, but researchers are not always able to detect or track such impacts from Earth. This means that we are sometimes caught unaware by the "rogue debris" created by the impacts.
Within NASA’s new FY2014 budget proposal lies a project known as the Asteroid Retrieval and Utilization Mission. This project would be the first to capture a small near-Earth asteroid and safely redirect it to a lunar orbit so that astronauts can visit and explore it. Such a mission would expand scientific knowledge of the origins of both humanity and the universe.
The giant Chicxulub crater in Yucatan is evidence that sometime around 65 million years ago a massive asteroid smashed into the earth wiping out most life that existed at that time, including all non-avian dinosaurs. While it is hard to imagine a similar scenario taking place today, there is currently little that we could do but sit and “pray.”
Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...
Asteroid Belt -- The Asteroid belt is a region of the solar system falling roughly between the planets Mars and Jupiter where the greatest concentration of asteroid orbits can be found. It is believed that, during the first million years of the solar system history, planets formed by accretion of planetesimals. Ripetute collisions led to the familiar rocky planets and to the gas giant's cores. However, in this zone of the system the strong gravity of Jupiter inhibited the final stages...
Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less Î”V than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...
