Granted it's in bold at the bottom of the release, but I almost missed it... this web-media feature has a bunch of imagery and discussion and analysis of all four sites:

Nice animation (and explanation) HERE of the four possible sites (definitely do a full screen on this).

Surprisingly regular pattern of cracks on Bennu's boulder ( from this picture ).
The beauty of natural physical processes common in the Universe... |

The down selection to a primary and backup sampling site could occur as early as today.
In the meantime here are a couple of article links. One is an update and another is about a close call that almost postponed the sampling a great deal. LINK: The midst of selection LINK: Engineers pull off rescue !!! Quote from the end of the second article: QUOTE NASA will announce the primary sample site, as well as a backup, on Dec. 12. Two final reconnaissance flyovers at even lower altitudes beginning in January will allow the OSIRIS-REx team to collect final, detailed images of these sites. |

It will be Nightingale. Osprey is the backup site.

New, detailed pictures of the surface of Nightingale, taken January 22, 2020 from 600 m - on the OSIRIS-REx website (and also nice mosaics).
Pictures: NASA/Goddard/University of Arizona, slightly changed. |

More nice boulders from a 600 m (pictures from OSIRIS-REx: NASA/Goddard/University of Arizona, slightly changed)
The first one looks a bit like cracked erratic with glacial polish ![]() |

From the OSIRIS-Rex website: "On Feb. 11, NASA’s OSIRIS-REx spacecraft safely executed a 0.4-mile (620-m) flyover of the backup sample collection site Osprey... Preliminary telemetry, however, indicates that the OSIRIS-REx Laser Altimeter (OLA) did not operate as expected during the 11-hour event. The OLA instrument was scheduled to provide ranging data to the spacecraft’s PolyCam imager, which would allow the camera to focus while imaging the area around the sample collection site. Consequently, the PolyCam images from the flyover are likely out of focus. The other science instruments... all performed nominally during the flyover... The mission team is currently reviewing the available data from the flyover in order to fully assess the OLA instrument..."

First official (approved by IAU) Bennu surface feature names: 11 boulders (Saxum) and 1 Regio.
Most prominent boulder (22 m high) is officially designated Benben Saxum. |

Time to update my map! No craters are named yet but I expect we will get a few more names later. When I can get a version of the new map without text I will put it into this map.

Google translate: saxum == stone. That's a new one to me.
I enjoy this sort of thing. Had to give my doctor wife a hard time when I discovered the posterior fossa isn't where I'd expect it to be. |

This is a new category in the Solar System nomenclature. So far, "saxum's" (actually: Saxa) names have been approved only for Ryugu (only 3, e.g. Otohime Saxum) and Bennu (11).
PS. When I hear: "posterior fossa", I think about one of these things (I know it's Chasma - not fossa - on Tethys, but it looks good): |
