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.

Watch “Live” as NASA’s OSIRIS-REx Nabs an Asteroid Sample

Today’s the day! The OSIRIS-REx spacecraft is going to reach out and boop asteroid Bennu! You can watch the broadcast here as the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission attempts to collect a sample of an asteroid on Tuesday, Oct. 20, at 6:12 pm EDT (5:12 pm CDT, 3:12 PDT).

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.

Asteroid Bennu has little pieces of Vesta on it

The asteroid belt is a chaotic place.  Things smash into each other, get thrown into completely different orbital planes, and are occasionally visited by small electronic spacecraft launched by humans.  All three things seem to have happened to the asteroid Bennu, which is currently being orbited by OSIRIS-REx, a mission launched by NASA in 2016.

The most recently released results from the mission show that Bennu might have small pieces of Vesta on it.  Given that Vesta is one of the biggest asteroid belt objects and Bennu is a near Earth asteroid millions of kilometers away from the asteroid belt, this hints at a pretty exciting past history for the asteroid currently being visited by NASA’s first asteroid sample return mission.

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.

These are the Boulders OSIRIS-REx is Going to Use to Navigate Down to the Surface of Bennu

Meet OSIRIS-REx’s “Guide Boulders.”

When the NASA spacecraft first arrived at asteroid Bennu over a year ago, the surface of the asteroid was much different than expected. Instead of a surface with large, smooth areas, nearly the entire surface is covered in boulders. That meant that NASA had to do a re-think of the sampling procedure.

Asteroid Bennu is Getting Some Official Names for its Surface Features

Late last summer, NASA and the International Astronomical Union’s Working Group for Planetary System Nomenclature (a.k.a WGPSN) approved the naming convention for features on Bennu, the asteroid currently being orbited and studied by the OSIRIS-Rex spacecraft. The naming theme chosen was “birds and bird-like creatures in mythology.”

The first twelve features thusly named have now been announced. But more importantly, some of these features will be instrumental in helping to guide OSIRIS-REx to the surface of the asteroid later this year.

OSIRIS-REx did its Closest Flyover Yet, just 250 Meters Above its Sample Site

NASA’s OSIRIS-REx is getting closer, physically and temporally, to its primary goal. The spacecraft arrived at Bennu at the end of 2018, and for just over a year it’s been studying the asteroid, searching for a suitable sampling site. To do that, it’s getting closer and closer.
