The U.S. Space Force has swapped rockets for an upcoming GPS satellite launch, moving to a SpaceX Falcon 9 while the investigation into an anomaly with ULA's Vulcan Centaur continues.

NASA’s Artemis II rocket and Orion spacecraft moved to the launch pad Friday, with a crewed moon flyby targeted for April after earlier delays.

And once again, the company the Pentagon is paying to launch it can’t answer the call. United Launch Alliance, a 50-50 joint venture between Boeing and Lockheed Martin, was supposed to launch the final satellite for the Space Force’s GPS Block III program this month.

The launch has been pushed back to 10:20 a.m.

SpaceX's Falcon 9 is set to launch 25 Starlink satellites from Vandenberg Space Force Base to low-Earth orbit at 10:16 p.m. Monday.

SpaceX launches, NASA's Artemis II mission and a planetary collision are among the latest news updates in FLORIDA TODAY's 321 Launch space newsletter.

Those were two of the updates given by the commander of Space Launch Complex-30 at a presentation on Thursday.
