Astronauts aboard the International Space Station have begun depressurizing the vestibule, which connects the Raffaello multipurpose logistics module to the Earth-facing port of the Harmony node. The process is expected to take about 90 minutes. Once that is complete, Atlantis Pilot Doug Hurley and Mission Specialist Sandy Magnus will use the space station robotic arm to remove Raffaello from Harmony and return it to Atlantis’ cargo bay.
