Sunday: NASA Asteroid Lander To Return With Samples

ABC News reports:

An asteroid NASA’s been tracking for nearly 25 years could impact Earth in the future, a new report reveals. First discovered in 1999, Bennu, the near-Earth asteroid, could possibly drift into the planet’s orbit and could hit the planet by September 2182, according to the OSIRIS-REx science team.

Bennu passes near Earth every six years and has had three close encounters with Earth in 1999, 2005, and 2011, experts said in the ScienceDirect study. There is a 1 in 2,700, or 0.037% chance that Bennu could hit Earth by 2182, scientists said.

If Bennu would hit Earth, it would release 1,200 megatons of energy, which is 24 times the energy of the most manmade nuclear weapon, according to IFLScience.

On Sept. 24, 2023, NASA’s OSIRIS-REx mission will make history by returning samples of the asteroid Bennu to Earth after seven years in deep space. Launched in 2016, the OSIRIS-REx spacecraft reached asteroid Bennu in October 2020 and collected samples from the near-Earth asteroid’s surface.

It will return those samples in a special capsule and parachute, with landing set for 10 a.m. EDT (1400 GMT) at Department of Defense’s Utah Test and Training Range near Dugway, Utah. The probe is currently about 1.8 million miles (2.8 million km) away, speeding toward Earth at roughly 14,000 mph (23,000 kph).
