Inside the Vertical Integration Facility (VIF) at Space Launch Complex 41 at Cape Canaveral Air Force Station (CCAFS) in Florida, United Launch Alliance (ULA) workers watch as the fourth and final solid rocket booster (SRB) for the United Launch Alliance Atlas V 541 rocket is lowered by crane on June 9, 2020. The SRB will be mated to the Atlas V booster. NASAs Mars 2020 mission with the Perseverance rover is scheduled to launch in July 2020, atop the Atlas V rocket from Pad 41. The rover is part of NASAs Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet. The rovers seven instruments 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.
