Live coverage: Falcon 9 rocket conducts static fire test

SpaceX published a livestream for the mission, suggesting it could launch its more than 400-foot-tall rocket by mid-March. There are still a number of outstanding items before that could happen, including the Federal Aviation Administration issuing a launch license.

SES announced Thursday it has tapped SpaceX for two additional Falcon 9 rocket launches from Cape Canaveral to deliver more Boeing-built O3b mPower broadband satellites into orbit, adding to a pair of Falcon 9 flights ordered by SES last year to launch the first batch of mPower platforms beginning in late 2021.

After years of studies, test-firings and a survey of U.S. industry in preparation for launch of a Mars Sample Return mission in 2026, NASA has settled on a solid-fueled design for a miniature rocket with a first-of-its-kind purpose: Launching a payload from Mars for a trip back to Earth.
