NASA has selected SpaceX and United Launch Alliance to deliver to orbit a joint U.S.-European oceanography mission and the next land imaging satellite in the Landsat series on Falcon 9 and Atlas 5 rockets.

The European Space Agency’s Aeolus winds observatory is set for liftoff aboard a Vega rocket to kick off a three-year mission to measure global wind profiles from an orbit nearly 200 miles (320 kilometers) above Earth.

Another batch of 52 Starlink satellites launched late Tuesday from Vandenberg Space Force Base in California, on the way to join SpaceX’s fleet of more than 4,000 spacecraft beaming broadband signals around the world.
