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. |
