Live coverage: Two satellites blast off on Ariane 5

A Proton rocket blasted off from the Baikonur Cosmodrome in Kazakhstan at 2040 GMT (4:40 p.m. EDT) Friday with Turkey’s Turksat 4B communications satellite.

Monday night’s blastoff of a Vega rocket from the northern shore of South America dispatched a 2,500-pound Earth imaging satellite for Europe and put on a light show across the tropical spaceport at the edge of the Amazon.

An experimental microsatellite built and owned by Astro Digital, a California-based company, rode Rocket Lab’s Electron rocket into orbit at 9:22 p.m. EDT Wednesday (0122 GMT Thursday) from New Zealand.
