NASA tests Flying Saucer shaped Mars Lander


NASA has a cool new toy. It looks like a flying saucer and will be used to land heavy cargo on Mars.

NASA works on new technology to land cargo on Mars. NASA calls this new spaceship Low-Density Supersonic Decelerator (LDSD).

Yesterday scientists and engineers at the NASA’s Jet Propulsion Laboratory in Pasadena performed the final tests of the LDSD test vehicle before going to Hawaii for its near-space test. The rocket-powered, saucer-shaped test vehicle will go into near-space from the Navy’s Pacific Missile Range Facility on Kauai, Hawaii, in June.

In the lab NASA performed a “spin table test” in which the 15-foot-wide, 7,000-pound test vehicle was spun up to 30 rpm to check its balance.

In mid-April, the vehicle will be flown to Kauai. During the June experimental flight test, a balloon will carry the test vehicle from the naval facility to an altitude of about 120,000 feet (36 kilometers). There, over the Pacific, it will be dropped and its booster rocket will kick in and carry it to 180,000 feet (55 kilometers), accelerating to Mach 4. Once in the very rarified air high above the Pacific, the saucer will begin a series of automated tests of two breakthrough technologies.

The supersonic inflatable aerodynamic decelerator (SIAD-R), which is an inflatable doughnut that increases the vehicle’s size and, as a result, its drag, will be deployed at about Mach 3.8. It will quickly slow the vehicle to Mach 2.5 where the parachute, the largest supersonic parachute ever flown, will deploy. About 45 minutes later, the saucer is expected to make a controlled landing onto the Pacific Ocean off Hawaii.

The upper layers of Earth’s stratosphere are the most similar environment available to match the properties of the thin atmosphere of Mars. The LDSD mission developed this test method to ensure the best prospects for effective testing of the new and improved landing technologies here on Earth.

The LDSD crosscutting demonstration mission will test breakthrough technologies that will enable large payloads to be safely landed on the surface of Mars, or other planetary bodies with atmospheres, including Earth. The technologies will not only enable landing of larger payloads on Mars, but also allow access to much more of the planet’s surface by enabling landings at higher-altitude sites.
