NASA wants to send ever-heavier spacecraft – along with humans at some point – to Mars. Along those lines the space agency successfully tested a flying saucer-like craft from the U.S. Navy's Pacific Missile Range Facility in Kauai, Hawaii in June. NASA says it is developing three flying saucer, or rather Low Density Supersonic Decelerator (LDSD) systems. The first two are supersonic inflatable aerodynamic decelerators -- very large, durable, balloon-like pressure vessels that inflate around the entry vehicle and slow it from Mach 3.5 or greater to Mach 2 or lower.
