CAPE CANAVERAL, Fla. — The countdown is ready to begin for NASA's biggest test flight of the year.
At 10:23 a.m. EDT (1423 GMT) today (Aug. 27), the countdown clock will start ticking down to the planned launch of NASA's Artemis 1 mission, an ambitious first flight to the moon by the agency's most powerful rocket ever — the Space Launch System (SLS) — and its Orion spacecraft. The uncrewed test flight is scheduled to launch Monday (Aug. 29) at 8:33 a.m. EDT (1233 GMT) from Pad 39B here at the Kennedy Space Center.
"This first launch is another step in the blueprint of our sustainable exploration of the solar system," Jim Free, NASA's associate administrator for exploration systems development, told reporters here in a briefing Friday.
