NASA TO TEST FLYING-SAUCER-LIKE DEVICE FOR MARS LANDINGS
NASA plans to launch a flying-saucer-shaped vehicle to test technology for landing heavy loads – and one day even people – on Mars. The Low-Density Supersonic Decelerator (LDSD) will be taken into the stratosphere from the Navy’s Pacific Missile Range Facility on Kauai. How the vehicle is launched – see IMAGE
After several weather delays, NASA successfully launched and recovered a “flying saucer” into Earth’s atmosphere Saturday to test technology that could be used to land on Mars.
Saturday afternoon, the ‘flying saucer’ splashed down in Pacific.
The test at the Kauai military range had been postponed several times since June 2 because of winds.
It may seem straight out of a B-movie, but the space agency says the launch had a serious purpose: to test technology that will help land spacecraft and someday humans on Mars.
NASA still relies on some of the basic designs developed more than 40 years ago to land the Viking spacecraft on Mars, principal investigator Ian Clark of NASA’s Jet Propulsion Laboratory said earlier this month.
The low-density supersonic decelerator, as it’s officially known, ascended into the skies dangling from a gargantuan balloon filled with helium. At 34 million cubic feet, the balloon filled the Rose Bowl, encasing the helium in a skin made of a high-tech film as thin as sandwich wrap.
After the balloon and its load soar to roughly 23 miles high, the balloon broke away from the vehicle and drop to Earth, the cue for a rocket attached to the saucer to fire. The rocket propelled the saucer to four times the speed of sound, duplicating the rapid clip of a spacecraft bound for Mars.
NASA’s latest rover on Mars, the Mars Science Laboratory, weighed about a ton. The new technology being tested would allow the landing of a load twice as heavy, and the use of multiple parachutes could mean even spacecraft of 20 to 30 tons could make a soft landing, Clark said.
At the test location high above the Earth, the air is as thin as the wispy atmosphere around Mars.
“We want to test them here — where it’s a lot cheaper — before we send them to Mars,” said project manager Mark Adler, also of the Jet Propulsion Laboratory.
