Driven by three RS-68A main engines, a United Launch Alliance Delta 4-Heavy rocket lifted off early Sunday from Cape Canaveral carrying NASA’s Parker Solar Probe on a historic mission to study the sun.

Onboard video cameras captured critical events during the 50th Atlas 5 rocket launch, beaming back views in stunning clarity of staging and spacecraft separation.
