SpaceX launched a Falcon 9 rocket at 8:51 a.m. EST (1351 GMT) Sunday from Cape Canaveral with the first in a new line of upgraded U.S. Air Force GPS navigation satellites. The launch was delayed five days due to technical and weather concerns.

Engineers ran into problems repressurizing the Artemis 2 moon rocket’s upper stage helium tanks overnight Friday, a problem that will require rolling the huge rocket off the launch pad and back to its processing hangar for troubleshooting. The work will push the already delayed mission from March to at least early April, officials said Saturday.

Veteran Russian commander Oleg Novitskiy, rookie flight engineer Pyotr Dubrov, and NASA astronaut Mark Vande Hei launched into orbit Friday from the Baikonur Cosmodrome in Kazakhstan at 3:42 a.m. EDT (0742 GMT). The crew members rode a Soyuz capsule in pursuit of the International Space Station, where docking occurred at 7:05 a.m. EDT (1105 GMT).
