It's a scene reminiscent of NASA's glory days, back when men still walked on the moon. A space capsule descends under a canopy of three orange-and-blue parachutes, swaying gently in the breeze. The spacecraft splashes down in the Pacific at a leisurely 15 miles an hour, and the chutes settle into the water beside it. A recovery boat rumbles into position beside the spacecraft, and divers hit the water.
