Photos: Atlas 5 rocket aims for International Space Station

The European Space Agency’s Solar Orbiter spacecraft — assembled in Britain and set for liftoff in February — has completed environmental testing in Germany and is scheduled to ride a cargo plane to NASA’s Kennedy Space Center in Florida to begin launch preparations Oct. 31, several weeks earlier than planned to avoid complications stemming from Brexit.

The launch of NASA’s Mars 2020 rover is less than a year away, and the steady pace of work inside the craft’s pristine assembly hall in California is keeping the mission on schedule for liftoff from Cape Canaveral next July, despite growing costs, according to mission managers.

The Falcon 9 rocket’s fifth flight of the year will take off from Cape Canaveral on Thursday, heaving the Thaicom 8 communications satellite into orbit on an easterly trajectory from Florida’s Space Coast.
