T-4 Minutes and Holding
Countdown clocks have temporarily paused at the T-4 minute mark. This is a planned, 15-minute hold expected to release at 10:59 p.m. EST. Liftoff of the Solar Orbiter spacecraft aboard a United Launch Alliance Atlas V rocket remains on schedule for 11:03 p.m.
Launch Weather Officer Jessica Williams briefed the launch team just a few minutes ago. There are barely any clouds, she reported, and no precipitation expected. The potential for ground winds remains, and the overall forecast predicts a 90% chance of favorable conditions at launch time.
