OSIRIS-REx from NASA arrived on the asteroid Bennu in December 2018. Over the previous 12 months, he has lengthy imagined the floor of the asteroid, in search of a the place to take a pattern. Though the spacecraft has a number of scientific targets and a set of devices to realize them, returning samples is the important thing goal.
Now, NASA has narrowed the selection to 4 potential sampling places on the floor of the asteroid.
The spacecraft performed a one – month overview of every of the 4 websites. This section, known as Recon A, was accomplished in July. Mission operators now have high-resolution photos of every of the websites, detailing their topography, albedo, coloration and the suitability of sampling.
It’s now time to scale back the 4 websites to 2: a major website and a backup website. However sadly, Recon A has proven that every of the 4 websites is hard, and sampling may not be taking place in addition to anticipated. Though every of the 4 websites has an acceptable fine-grained materials, lower than 1 inch, they’re additionally harmful.
