Also doing a surgical procedure. On the bottom of the sea. When the doctor is in Canada.
From Tariq Malik at Space.com:
Long-term moon missions would be safer if astronauts could receive the best health care possible without having to send a range of specialists to take care of any eventuality. The work aboard NEEMO 9 paves the way for surgery on the moon that is performed by doctors on Earth -- which (do I have to say it?) is extremely cool.
One of the key goals for the NEEMO 9 crew included the assembly and operation of a surgical robot designed to allow physicians to dress wounds remotely with only an Internet link-up between them.
Canadian doctor Mehran Anvari, a veteran of telemedicine experiments with past NEEMO crews, directed the robot to suture a gash inside Aquarius. But instead of working aboard Aquarius, or even aboard a surface ship, Anvari sat at a workstation in the Canadian city of Hamilton, Ontario, where he directs the Center for Minimal Access Surgery at McMaster University.
