Jason 3 pre-launch news conference

Launching for the 20th time from the jungle of South America, a Russian-built Soyuz booster rocketed into orbit Wednesday with a new eye in the sky for the French military, the first in a series of upgrades planned for the country’s defense satellites over the next five years.

NASA wants to fly an astronaut on Russia’s next Soyuz mission to the International Space Station in April, a measure the agency says would ensure a continued U.S. presence on the research outpost in case of delays in the launch of SpaceX’s next Crew Dragon flight.

Nine Merlin engines on the first stage of SpaceX’s next Falcon 9 rocket briefly fired up on a Cape Canaveral launch pad Wednesday, and the launcher cleared a customary pre-flight checkout in preparation for liftoff early Sunday with a Canadian-owned communications satellite.
