Live coverage: Atlas 5 countdown and launch journal

Four NASA satellites that will create a constellation of formation-flying spacecraft were placed aboard their shared United Launch Alliance Atlas 5 rocket Friday.

SpaceX hurled a secret cargo into space for the U.S. government’s spy satellite agency Saturday, the 30th rocket launch to fly into Earth orbit from pads on Florida’s Space Coast in 2020. The Falcon 9 flight broke an annual record for missions to reach orbit from the Florida spaceport that stood for 54 years.

A Russian Proton rocket lifted off at 1017 GMT (6:17 a.m. EDT) Wednesday from the Baikonur Cosmodorme in Kazakhstan. After a marathon 16-hour-long launch sequence, the Proton and its Breeze M upper stage will deploy the Eutelsat 5 West B video broadcast satellite and a robotic satellite servicing payload aiming to attempt the first-ever docking in geosynchronous orbit.
