English: Inside the Rotation, Processing and Surge Facility high bay at NASA’s Kennedy Space Center in Florida, engineers and technicians with Jacobs Engineering on the Test and Operations Support Contract have removed the environmental cover from the first of two pathfinders, or test versions, of solid rocket booster segments for NASA’s Space Launch System rocket. Preparations are underway to perform a simulated grain inspection of the booster’s interior. The Ground Systems Development and Operations Program and Jacobs will conduct a series of lifts, moves and stacking operations using the booster segments, which are inert, to prepare for Exploration Mission-1, deep-space missions and the journey to Mars. The pathfinder boosters arrived at Kennedy from Orbital ATK in Utah aboard an Iowa Northern train owned by Goodloe Transportation of Chicago.
