61st Session of the United Nations Office for Outer Space Affairs "Committee on the Peaceful Uses of Outer Space"
COPUOS's 61st Session
The United Nations Office for Outer Space Affairs (UNOOSA) runs several annual meetings on space issues. Their "Committee on the Peaceful Uses of Outer Space" (COPUOS) is meeting in Vienna, Austria right now. Technically, it is COPUOS's 61st Session, and the meetings are scheduled from March 28 to April 8, 2022.
COPUOS was set up in 1959, and deals entirely with international cooperation on the peaceful uses of outer space.
The U.S. has 4 scheduled presentations, which I have linked below.
The US Head of Delegation, Emily Pierce, will present (or has already presented) the U.S.'s position on several topics. Ms. Pierce is the Attorney-Adviser, Office of the Legal Adviser, U.S. Department of State. (That's according to last year's list of participants. I was unable to verify current titles and responsibilities. In any event, she is this year's Head of Delegation.) Also, I would bet she works through the "U.S. Mission to International Organizations in Vienna" (UNVIE) because they liaise with UNOOSA and the links below are all from UNVIE's website.
