OSIRIS-REx Reveals Secrets of Bennu — The Doomed Asteroid

The spacecraft OSIRIS-REx has reveled a wealth of new information about Bennu, a large, ancient asteroid. On March 19th, researchers released a wide range of scientific papers, providing a new look at this diamond-shaped body. New data shows Bennu is covered in massive boulders, which could hinder the spacecraft from gathering materials from the surface. Researchers have also spotted evidence water once existed on the body from which Bennu broke free. Gravity on the asteroid was also found to act in a strange manner, causing anything just outside its equator to be pulled toward the center of the asteroid, and shot into space.

Want to Blow Up an Asteroid? It’s Harder than You Think

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.

OSIRIS-REx Arrives at the Asteroid Bennu – Tucson and the World Celebrates

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.
