From the California News Times, June 9, 2021: There is a new robotics project at Fermilab called Argonaut and its mission is to sail into a sea of liquid argon kept at minus 193 degrees Celsius to monitor the condition inside the ultra-low temperature particle detector.

From Laboratory Equipment, May 31, 2021: Fermilab engineer Bill Pellico wondered if it would be possible to make the interior cameras movable using liquid argon detectors to inspect the inside of detectors.
