This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Cape Canaveral with the SBIRS GEO Flight 4 satellite for U.S. military infrared reconnaissance.

SpaceX has postponed its next launch from the Kennedy Space Center indefinitely to examine data from a recent payload fairing test for another customer.
