Curiously, the featured image does picture the Earth setting over a lunar edge. This was possible because the image was taken from a spacecraft orbiting the Moon - specifically the Lunar Reconnaissance Orbiter (LRO). In fact, LRO orbits the Moon so fast that, from the spacecraft, the Earth appears to set anew about every two hours.

Above all, rating a spacecraft is more than a set of requirements, a process, or a certification. It involves a mindset, instilled by leadership, where each person feels personally responsible for their piece of the design and for the safety of the crew.
