United Launch Alliance has released a replay of the May 5 liftoff of NASA’s InSight mission to Mars aboard an Atlas 5 rocket, as viewed by aft- and forward-facing cameras on the two-stage launch vehicle.

SpaceX’s next Falcon 9 rocket ignited its Merlin main engines for several seconds Thursday at Kennedy Space Center’s pad 39A ahead of a planned launch next week.

Two U.S.-built Intelsat communications satellites destined for different missions fired into space from French Guiana just after sunset Wednesday, vaulting due east over the Atlantic Ocean before separating from their Ariane 5 launcher right on target in geostationary transfer orbit.
