NASA’s Martian Flying Saucer Descent Vehicle


NASA is building its own flying saucer as part of a project to get bigger payloads to Mars. The disk-shaped object is called a Low Density Supersonic Decelerator due to fly for the first time this June.

During its Mach 3.5 descent, it will inflate like a pufferfish to increase atmospheric drag, slowing its speed to about twice the speed of sound. That will trigger the deployment of a super-strong 100-foot-wide (33.5-meter-wide) parachute, which should slow down the test vehicle.

NASA had to use a complex, rocket-powered sky crane to get its 1-ton Curiosity rover safely down to the surface of Mars in 2012, but the payloads required for human missions to Mars are expected to weigh significantly more. The sky-crane system can’t handle payloads that heavy.

About Heretic

I design video games for a living, write fiction, political theory and poetry for personal amusement, and train regularly in Western European 16th century swordwork. On frequent occasion I have been known to hunt for and explore abandoned graveyards, train tunnels and other interesting places wherever I may find them, but there is absolutely no truth to the rumor that I am preparing to set off a zombie apocalypse. Nothing that will stand up in court, at least. I use paranthesis with distressing frequency, have a deep passion for history, anthropology and sociological theory, and really, really, really hate mayonnaise. But I wash my hands after the writing. Promise.
