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.

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).

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 is blanketed by rocks and huge boulders. And now that the OSIRIS-REx spacecraft is taking a close look at those rocks, researchers are able to see something surprising for an airless body: the rocks have tiny cracks and fissures.

The date is finally set for OSIRIS-REx’s sampling maneuver. The spacecraft has been at asteroid Bennu since the end of December 2018. During that time, it’s found a few surprises, and mapped the surface in great detail.
Now, we can circle October 20th on our calendars, as the date OSIRIS-Rex will collect its sample.

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.

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.

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.

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.

While the OSIRIS-REx spacecraft was orbiting asteroid Bennu,
one of the instruments on board happened to catch a glimpse of a black hole ‘out
of the corner of its eye,’ so to speak.
While intently focusing on the asteroid, the Regolith X-Ray Imaging Spectrometer (REXIS) happened to catch the X-rays from a newly flaring stellar mass black hole. While the flare occurred 30 thousand light years away, the flash in distant space was visible just off the limb of asteroid Bennu, in the edge of the instrument’s field of view.
