NASA and FEMA are working together to devise strategies in case a massive asteroid or comet is found heading toward the Earth. Although asteroids hit our planet on a regular basis, few cause significant damage. In 2013, a meteor exploded over the city of Chelyabinsk in Russia, injuring 1,100 people. Roughly 66 million years ago, an asteroid the size of Mount Everest hit the Earth, ending the age of dinosaurs. Researchers do not currently know of any asteroid or comet headed on a collision course with our planet.Read More Is Earth Ready for the Next Asteroid Strike?
Science fiction is filled with stories of astronauts blowing up asteroids just before they strike the Earth. But, doing so could be even worse than doing nothing, as fragments of these bodies could impact the Earth in multiple locations, like a shotgun blast. Now, new research from Johns Hopkins University shows even attempting to blow up an asteroid might prove futile. Computer models of impacts between two asteroids show that such events would likely result in short-term fragmenting of the bodies, but these pieces would come together again within hours, recreating a mass much like the original asteroid. Researchers are on the lookout for asteroids and comets heading toward the Earth that could endanger areas from small cities to the entire planet.Read More Want to Blow Up an Asteroid? It’s Harder than You Think
On the night of Monday, January 21st, asteroid 2019 AX8 passed 6.9 million kilometers (or 4.3 million miles) from the Earth, after first being seen just two weeks before. The asteroid measured between 28 and 63 meters (equivalent to 92 to 207 feet) across, roughly half the height of the Great Pyramid of Giza. To face threats like this one, NASA is planning to launch the Double Asteroid Redirection Test (called DART) in 2022, in an effort to change the course of such a body. The rocket will collide with the asteroid Didymos B, the smaller of two asteroids which orbit each other. This test will be the first-ever attempt to redirect an asteroid.Read More Asteroid AX8 Skims Earth as NASA Prepares Plans to Save Planet from Future Threats
The OSIRIS-REx spacecraft arrived at the asteroid Bennu on December 3rd. This mission will return samples from this body to the Earth for study by researchers. Bennu was discovered in 1999, and this carbon-rich asteroid is believed to be older than the solar system. Researchers hope the mission will help teach us more about the ancient solar system and the formation of life on Earth. The sample material is scheduled to land in the desert of Utah in the year 2023. This is the first U.S. mission to land on an asteroid.Read More OSIRIS-REx Arrives at the Asteroid Bennu – Tucson and the World Celebrates
A new plan from NASA could help prevent mass disaster if the Earth is hit by a giant meteor. Although no object is currently predicted to strike our home planet, this new report outlines ways to detect and deflect dangerous objects, as well as contingency plans should an impact occur.Read More NASA Reveals New Plan to Save Earth from Asteroids
