NASA Prepares OSIRIS-REx to Safely Store Leaking Asteroid Samples

NASA’s robotic spacecraft Osiris-Rex is set to start on Tuesday a fragile procedure to retail outlet the cherished particles it scooped up from the asteroid Bennu, but which had been leaking into space when a flap got wedged open up.

The probe is on a mission to obtain fragments that scientists hope will help unravel the origins of our photo voltaic system, but that strike a snag following it picked up too massive of a sample.

Fragments from the asteroid’s surface are in a collector at the stop of the probe’s three-metre (10-foot) arm, little by little escaping into room since some rocks have prevented the compartment closing entirely.

That arm is what arrived into call with Bennu for a several seconds very last Tuesday in the end result of a mission introduced from Earth some four years in the past. 

The probe is believed to have collected some 400 grams (14 ounces) of fragments, considerably much more than the bare minimum of 60 grams essential, NASA stated beforehand.

Experts need to have to stow the sample in a capsule that is at the probe’s centre, and the operation was moved up to Tuesday from the prepared November 2 date because of to the leak.

“The abundance of materials we collected from Bennu created it attainable to expedite our selection to stow,” stated Dante Lauretta, job main.

OSIRIS-REx is established to appear home in September 2023, ideally with the greatest sample returned from space considering the fact that the Apollo period.

The stowing procedure will get various times, NASA mentioned, due to the fact it requires the team’s oversight and enter as opposed to some of OSIRIS-REx’s other operations that run autonomously.

Soon after each step in the course of action the spacecraft will deliver data and photos back to Earth so experts can make sure almost everything is proceeding accurately.

The probe is so considerably absent that it takes 18.5 minutes for its transmissions to reach Earth, and any sign from the manage area requires the similar quantity of time to get to OSIRIS-REx.
