I'm not aware of any specific mission or project called "OSIRIS-REx STraile" as of my last knowledge update in September 2021.
However, it's possible that this is a reference to a space mission or scientific project that was initiated after that date or a term with a specific context.
If you could provide more information or context about "OSIRIS-REx STraile," I would be happy to help you with a description or any related information I may have.
