Asteroid AX8 Skims Earth as NASA Prepares Plans to Save Planet from Future Threats

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.

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.

110 Years After Tunguska, Astronomers Ready a New Telescope to Search for Threatening Asteroids from Space

Astronomers are building a new telescope designed to search for asteroids which could threaten the Earth. Called the Large Synoptic Survey Telescope, this new observatory under construction in Chile is expected to find 65 percent of the objects which could threaten our home world. It was 110 years ago when an object from space caused a massive blast in Siberia which flattened trees in an area 2,000 square kilometers in size.
