The two missions will be launched within roughly three weeks of one another from New Zealand. Liftoff of the Electron rocket with the PREFIRE-1 satellite occurred at 7:41 p.m. NZST (3:41 a.m. EDT, 0741 UTC) on Saturday.

SpaceX’s Falcon 9 rocket disintegrated shortly after launch from Cape Canaveral on Sunday, dealing a blow to the entrepreneurial space company and NASA’s supply chain to the International Space Station.

Keeping up a tradition dating back to the dawn of the Space Age, a Russian Soyuz rocket emerged from a hangar at the Baikonur Cosmodrome in Kazakhstan before sunrise Saturday for rollout to Launch Pad No. 1 at the Central Asia space base, moving into position for liftoff Monday with a U.S.-Russian-Canadian crew heading for the International Space Station.
