Video: Antares rocket returns to flight with new engines

The last in an older generation of spin-stabilized Chinese weather satellites launched Tuesday toward a perch more than 22,000 miles over the equator, the start of a mission of at least four years monitoring tropical cyclones and other weather systems across Africa and Asia.

SpaceX is gearing up for the next big leap in the development of the next-generation Starship heavy-lift launch vehicle with a test flight to more than 40,000 feet over the Texas Gulf Coast as soon as Tuesday.

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into space from Cape Canaveral with NASA’s Mars 2020 mission.
