Two communications satellites owned by Saudi Arabian and Indian operators rocketed into orbit Tuesday on top of a European Ariane 5 rocket, the first of up to 13 launches planned from French Guiana this year.

A United Launch Atlas 5 rocket is set to launch the U.S. Air Force’s fifth Advanced Extremely High Frequency communications satellite from Cape Canaveral. This timeline shows the major mission events planned over a nearly six-hour flight to an optimized geostationary transfer orbit.

The European Space Agency has confirmed a parachute for the ExoMars rover mission set for launch next July failed during a test over Sweden earlier this month, the project’s second parachute test accident since May.
