Watch the Falcon 9 launch from pad 39A

The NROL-167 mission is the fourth launch to add satellites to the National Reconnaissance Office’s so-called “proliferated architecture” constellation. Liftoff happened at 10:13 a.m. PDT (1:13 p.m. EDT, 1713 UTC).

Russian cosmonaut Alexey Ovchinin and NASA astronaut Nick Hague landed safely downrange in Kazakhstan on Thursday after a Soyuz booster failure cut short their ascent into orbit from the Baikonur Cosmodrome toward the International Space Station. The emergency landing was the first Soyuz in-flight abort since 1975.

Sunday’s Falcon 9 rocket failure may have blemished SpaceX’s success record, but the mishap will not keep the entrepreneurial space company from competing for U.S. military launch contracts with rival United Launch Alliance, according to an Air Force general.
