Mars 2020 Adaptive Caching Assembly (ACA) Arrival

A close-up view of NASA’s C-130 aircraft that carries the Adaptive Caching Assembly (ACA) for NASA’s Mars Perseverance rover as it arrives at Kennedy Space Center’s Launch and Landing Facility in Florida on May 11, 2020. The ACA consists of seven motors and more than 3,000 parts, all working in unison to collect samples from the surface of Mars. A chief component of the assembly is the Sample Handling Arm, which will move sample tubes to the main robotic arm's coring drill and then transfer the filled sample tubes into a space to be sealed and stored. The Mars Perseverance rover is scheduled to launch in mid-July atop a United Launch Alliance Atlas V 541 rocket from Pad 41 at nearby Cape Canaveral Air Force Station. The rover is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet. The rover will search for habitable conditions in the ancient past and signs of past microbial life on Mars. The Launch Services Program at Kennedy is responsible for launch management.
