Photos: Atlas 5 rolls out for launch

Intelsat and SES, operators of the two largest fleets of geostationary communications satellites, have ordered 10 spacecraft from Maxar, Northrop Grumman and Boeing for launches beginning in 2022 to replace C-band capacity being transitioned to 5G cellular network services.

The Space Force says it changed the nickname of a GPS navigation satellite launched in June from Columbus to instead honor Matthew Henson, a Black explorer on the first expedition to the North Pole more than a century ago, “to acknowledge a fuller history of courageous explorers and pioneers.” The military’s next GPS navigation satellite, set for launch Friday night, is nicknamed Sacagawea.

Delays have set up the possibility of up to three rocket launches this weekend from different pads along Florida’s Space Coast, including two SpaceX missions on Sunday that could set a company record for the shortest span between two Falcon 9 rocket launches. But in the world of ever-changing launch schedules, numerous factors such as weather and technical issues could thwart launch plans this weekend.
