After a test flight in 2018, the Orion Spacecraft will splash into the Pacific Ocean near San Diego, at which point Navy Divers and Coast Guard and Air Force rescue workers will need to recover the uncrewed spacecraft. The mission will be a practice run in preparation for an eventual trip to Mars. Here, workers practice their rescue techniques inside the Neutral Buoyancy Laboratory at NASA's Johnson Space Center in Houston this week. NASA/Radislav Sinyak
