OSIRIS-REx Did One Last Close Flyby of Asteroid Bennu. It’s Almost Time to Come Home

After more than two years in orbit around asteroid Bennu, NASA’s OSIRIS-REx spacecraft is ready to come home. It’s bringing with it a pristine sample of space rocks that geologists here on Earth are eager to study up close. The sample will arrive in September 2023, but we won’t have to wait nearly that long for new data from OSIRIS-REx. Last week, the probe carried out one final flyby of Bennu, in an effort to photograph the sample collection site. The photographs are being downlinked now, and should be here by midweek.

If you’ve been following the OSIRIS-REx mission, you probably already know why scientists are keen to see these photographs, but if you haven’t, hold on to your hats – it’s a wild story.

OSIRIS-REx is Heading for Home in May

The OSIRIS-REx team decided to delay the spacecraft’s departure from asteroid Bennu for two months. The departure window opens in March 2021, and the original plan had OSIRIS-REx setting course for Earth on March 3, to bring home the asteroid samples it collected last October.

Now, a revised timeline has the spacecraft leaving Bennu on May 10, 2021. This won’t affect the target delivery data of September of 2023, but it will allow for more observations of the asteroid.

OSIRIS-REx Collected So Much Material, the Sample Capsule Overflowed. Time to Bring it All Home.

Is there such as thing as too much asteroid?

Scientists and engineers for NASA’s OSIRIS-REx decided to perform an “early stow” of the sample from Asteroid Bennu collected by the spacecraft on October 20, because the collection container is full-to-overflowing, possibly jamming the collector head from sealing shut.

Success! OSIRIS-REx Touches Asteroid Bennu to Collect Samples

Out in the asteroid belt, 207 million miles (334 million km) from Earth, a little spacecraft briefly touched down on the surface of Asteroid Bennu today, attempting to collect samples of dust and rocks.

NASA’s OSIRIS-REx spacecraft (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) spent about 10 seconds on the ancient asteroid to collect samples, slated to come back to Earth in 2023.  While mission scientists and engineers need to confirm that samples from the asteroid were collected, preliminary data show that every step of the procedure went as planned.

Just A Couple Of Weeks From Now, OSIRIS-REx Will Grab A Sample From Bennu

NASA is about to achieve another first for their organization. In about three weeks time, on October 20th, the OSIRIS-REx spacecraft will descend to Bennu’s surface, briefly touch down, and collect a sample from the asteroid. The spacecraft will collect a minimum of 60 grams (2 oz.) of material for return to Earth.

OSIRIS-REx Descended Down to Just 75 Meters Above the Surface of Bennu in a Recent Test

NASA’s OSIRIS-REx spacecraft is getting ready for its big moment. OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is at asteroid Bennu, preparing to collect a sample of ancient rock. And collecting that sample means taking step after meticulous step.
