So No New Earth Trojans, But OSIRIS-REx’s MapCam Surpassed Expectations

Remember when I mentioned that NASA’s OSIRIS-REx spacecraft was going to be scanning for “Trojan” asteroids at Earth-Sun L4? Well the results are in and survey says: no new Trojans (besides 2010 TK7, which we already knew about.) But the search wasn’t in vain—it gave mission scientists a chance put the spacecraft’s OCAMS instruments to the test and they passed with flying…

NASA’s OSIRIS-REx Will Search for Asteroids Caught In Earth’s Orbit

Launched on Sept. 8, 2016, NASA’s OSIRIS-REx spacecraft is heading out into the main asteroid belt beyond the orbit of Mars to meet up with the 1,600-foot-wide asteroid Bennu. Ultimately OSIRIS-REx will map and collect a sample of Bennu’s surface, returning it to Earth in 2023. But while it’s still traveling through near-Earth space in…

Say Hello To Our Little Friend

On July 27, 2011, scientists announced the discovery of a small asteroid that shares its orbit with Earth: 2010 TK7, a  1,000-foot-wide asteroid, precedes our planet within the same path we take around the Sun. It’s currently located about 50 million miles away in a position known as a Lagrange point (L4, to be exact) where…
