The crew of the NASA tugboat Clermont II navigates a barge of super-cool liquid oxygen through the 7 -mile canal system at SSC prior to a Space Shuttle Main Engine test.

NASA tugboat Clermont II arrives at the B-2 Test Stand the day after a hot fire test of the core stage for the first flight of NASA’s Space Launch System rocket, Saturday, Jan. 16, 2021, at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. During the test the four RS-25 engines fired for a little more than one minute and generated 1.6 million pounds of thrust. The hot fire is the final test of the Green Run test series, a comprehensive assessment of the Space Launch System’s core stage prior to launching the Artemis I mission to the Moon.
