How was Atlantis configured internally to maximize the cargo delivered to the ISS?
Flying in a disposition configuration utilizing the Payload Gear Bay like a massive trunk
To achieve the primary goal of maximizing inventory delivery to the ISS, Atlantis flew in what was described as a 'disposition' configuration. This involved utilizing the Payload Gear Bay, essentially turning it into a massive trunk to carry the most cargo possible, including the MPLM Raffaello. Engineers had to conduct fascinating logistics, scrutinizing every square inch of available volume to squeeze in maximum supplies. This requirement meant that the flight profile, including thrust levels and SRB burn duration, needed precise calculation to ensure the heavy mass could still achieve orbital insertion safely.
