This version of the Atlas V has launched a number of powerful payloads over the years, including Curiosity and Submit Mars rover.
The rocket blasted off toward the launch pad on Friday (December 3), traveling 550 meters from ULA’s vertical integration facility to the platform.
There are two satellites tucked into the payload streamer, each with a series of technology models and experiments that will be tested in orbit.
Most payloads are flagged, which is sponsored by the US Army’s Space Testing Program – a division that oversees space-related activities at the Department of Defense. However, the two largest satellites, known as STPSat-6, also carry NASA’s New Laser Communications Payload.
Also on board is a National Nuclear Security Administration payload designed to detect nuclear explosions from space.
