The most powerful configuration of United Launch Alliance’s Atlas 5 rocket blasted off April 14 from Cape Canaveral, hauling multiple U.S. Air Force satellites to a perch high above the equator after piercing a clear evening sky over Florida’s Space Coast with 2.6 million pounds of thrust.

NASA’s Perseverance rover, contained inside its aeroshell for a searing plunge into the Martian atmosphere next year, has been cocooned inside the payload shroud of its Atlas 5 launcher and mated with the rocket ahead of liftoff from Cape Canaveral scheduled for July 30.

The mission, dubbed Amazon Leo 6 by United Launch Alliance and Leo Atlas 6 (LA-06) by Amazon Leo, is the 10th batch of production satellites launched to orbit. Liftoff from pad 41 at Cape Canaveral Space Force Station is scheduled for 8:53:30 p.m. EDT (0053:30 UTC).
