KENNEDY SPACE CENTER, Florida—The two-day countdown for the launch of NASA's Artemis II mission began Monday evening, with clocks timed for the first of six opportunities in early April to send a crew of four astronauts around the far side of the Moon.
Liftoff from Launch Complex 39B at Kennedy Space Center in Florida is scheduled for a two-hour launch window opening at 6:24 pm EDT (22:24 UTC) on Wednesday. NASA has backup launch opportunities each day through Monday, April 6, or else the mission will have to wait until the end of the month.
Mission managers said Monday that all systems were looking good for launch this week. The weather forecast is favorable, with an 80 percent chance of acceptable conditions for liftoff Wednesday. The only weather concern at the launch site in Florida is a low chance of rain showers and cloud cover that could present a risk of lightning. But with a two-hour launch window, there should be plenty of time to wait out any scattered storms.
