Debuting lighter structural components to carry heavier satellites into orbit, a Russian Proton rocket fired into space from Kazakhstan on Thursday and successfully placed a U.S.-built television broadcast craft into orbit for Intelsat and DirecTV.

Amazon has selected United Launch Alliance’s Atlas 5 rocket for nine missions from Cape Canaveral to deploy satellites for the Kuiper internet constellation, a fleet designed to eventually number more than 3,200 spacecraft, the companies announced Monday.

SpaceX fired up a Falcon 9 rocket at Cape Canaveral Wednesday in a pre-flight test for a Starlink satellite launch Sunday, moving closer to the company’s final mission before sending two NASA astronauts into orbit for the first time May 27.
