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.

This collection of official NASA photographs captures the United Launch Alliance Atlas 5 rocket rolling to the pad on Monday, successfully blasting off Tuesday and the Cygnus freighter arriving at the International Space Station on Saturday morning.

Russian Soyuz commander Alexander Misurkin and two U.S. astronauts — flight engineers Mark Vande Hei and Joe Acaba — lifted off Tuesday from the Baikonur Cosmodrome in Kazakhstan. The trio began their six-hour journey to the International Space Station with a launch aboard a Soyuz rocket at 2117 GMT (5:17 p.m. EDT), and docking occurred at 0255 GMT (10:55 p.m. EDT).
