SpaceX conducts engine test fire for communications satellite launch (members only)

Bound for an orbital rendezvous with the International Space Station on Wednesday, a commercial Cygnus freighter was successfully launched by an Atlas 5 rocket Sunday to restart American cargo deliveries to the research outpost.

SpaceX’s tenth launch of the year took off Tuesday from California’s Central Coast on a unique ridehsare mission to add satellites to Iridium’s communications network and replace two Earth science satellites which ended their observations last year.

The next launch of a SpaceX Falcon Heavy rocket has been delayed from July to October to await the readiness of its U.S. military payload, and the following Falcon Heavy flight has been rescheduled from late this year to some time in 2022, military officials said.
