United Launch Alliance’s first full-scale Vulcan booster with two Blue Origin BE-4 engines arrived at Cape Canaveral Space Force Station on Saturday, the first time in more than a decade that a core stage from a new family of orbital-class rockets has rolled into the Florida launch facility.

A SpaceX Falcon 9 rocket was raised vertical at Space Launch Complex 4-East at Vandenberg Air Force Base in California on Sunday ahead of a planned liftoff with Argentina’s SAOCOM 1A radar observation satellite, and the first landing of a SpaceX booster on the U.S. West Coast.

A new optical Earth observation satellite launched by China Monday joins the country’s remote sensing network for land surveys, urban planning, and agriculture monitoring.
