NASA Makes History by Successfully Landing a Spacecraft on an Asteroid

A NASA spacecraft touched down on an asteroid for the first time history.

NASA’s OSIRIS-REx has briefly landed on the Bennu asteroid, located 200 million miles from Earth. It was a quick touch-and-go (TAG) type of landing that allowed the spacecraft’s robotic arm to gather dust and pebbles from the asteroid that will be delivered to Earth for analysis in 2023.

These samples will give scientists a rare glimpse into the early solar system, as Bennu is an ancient asteroid formed billions of years ago. The particles sampled on its surface may help us understand the building blocks of our own planet. This historic mission has been over a decade in the making, and its success shows the incredible technological advances we’re achieving.

“Today’s TAG maneuver was historic,” said Lori Glaze, Planetary Science Division Director at NASA Headquarters in Washington. “The fact that we safely and successfully touched the surface of Bennu, in addition to all the other milestones this mission has already achieved, is a testament to the living spirit of exploration that continues to uncover the secrets of the solar system.”

According to preliminary data, the collection was a success. If this is confirmed, OSIRIS-REx will start heading back towards Earth in March 2021. If not, another collection attempt will occur in January. OSIRIS-REx will need to have collected about 60 grams of material—roughly the size of a candy bar – for the mission to be declared successful.

So space fans, let’s keep our fingers crossed!
