#67 OSIRIS-REx NASA mission scientist Greg Brennecka brings us up to date on the incredible early findings from the Bennu asteroid sample.

Cosmic Coffee Time with Andrew Prestage

In September 2023, Greg Brennecka stopped by to preview the return to Earth of the OSIRI-REx asteroid Bennu sample return capsule. The sample landed safely and the mission scientists like Greg Brennecka have started their analysis. Some of our toughest questions are being answered by the data already. How old is Bennu? Is there organic material? Where was the asteroid formed? Is Bennu different from what we expected?
But hasn't been all smooth sailing. The mission team had to go into full innovation mode to overcome some early difficulties.
And we've only just begun!
