ensure the United Launch Alliance-built rocket is ready for liftoff
during the rover’s 23-day launch window. The Atlas Spaceflight
Operations Center, ULA’s launch team, a few miles away, powered up the
Atlas 5 rocket and ran the rocket through a practice countdown. During
the test — called a “wet dress rehearsal” — ULA loaded super-cold liquid
hydrogen and liquid oxygen into the Atlas 5’s Centaur upper stage, and
pumped liquid oxygen into the Atlas first stage booster.
