Artemis I Prelaunch

NASA’s Space Launch System (SLS) rocket with the Orion spacecraft aboard is seen atop the mobile launcher at Launch Pad 39B, Saturday, Sept. 3, 2022, as the Artemis I launch teams load more than 700,000 gallons of cryogenic propellants including liquid hydrogen and liquid oxygen as the launch countdown progresses at NASA’s Kennedy Space Center in Florida. NASA’s Artemis I flight test is the first integrated test of the agency’s deep space exploration systems: the Orion spacecraft, SLS rocket, and supporting ground systems. The launch director waived off today’s Artemis I launch attempt at approximately 11:17 a.m. EDT. Photo Credit: (NASA/Keegan Barber)
