SpaceX called off a planned Falcon 9 liftoff from Space Launch Complex 4E at Vandenberg Space Force Base, according to Spaceflight Now. The mission was carrying an unspecified number of satellites for a U.S. Space Force national security payload.

With the original attempt scrubbed, teams are now aiming for the backup opportunity on Wednesday, Sept. 16. The four-hour launch window opens at 6 p.m. PDT (9 p.m. EDT / 0100 UTC Thursday), giving SpaceX several chances within that span to send the rocket skyward.

Details on the exact satellites and their purpose remain undisclosed, consistent with the classified nature of many Space Force missions. Spaceflight Now is providing live coverage as the countdown resumes.
