Important dates:

  • Notice of intent to propose (mandatory): Due April 14
  • Sample request submission: Due May 1
  • Decision announcement: No later than early July
  • Sample distribution: July, 2023

Please check the Ryugu sample catalog and consider your research proposal based on the information described in the guidebook.

Anybody who wants to submit a sample request for the third AO, please login to your account and register by April 14. The proposal submission deadline is May 1.

Because samples from B-type asteroid Bennu will be returned by OSIRIS-REx in this September, this AO will be the last chance to study Ryugu samples before their return.
