Playbook: “If all goes well, in six days, the unmanned Orion capsule — which can accommodate four astronauts in future missions — will begin orbiting the moon from a distance of some 43,000 miles from the lunar surface. On the way there, Orion will release 10 shoebox-sized research satellites called CubeSats. After 42 days, on October 10, Orion will splashdown back on Earth, entering our atmosphere at 25,000 miles per hour before parachuting into the Pacific near southern California.”
