NASA’s LDSD flying saucer slated for first near-space flight
NASA’s LDSD flying saucer slated for first near-space flight
NASA’s rocket-powered test vehicle is scheduled to take to the skies for its first near-space test from U.S. Navy’s Pacific Missile Range Facility (PMRF) located on Kauai, Hawaii within the next few days. The Low-Density Supersonic Decelerator (LDSD) project’s flying saucer appearance makes it look like it’s straight out of a Steven Spielberg film. Planned to test out reentry technologies it has…

Rocket Sled Testing at China Lake (NASA, International Space Station, 03/29/12) by NASA's Marshall Space Flight Center Via Flickr: Hello Flickr friends! I highly recommend watching the video linked at the end of this caption. VERY cool stuff...! NASA recently performed a trial run on a rocket sled test fixture, powered by rockets, to replicate the forces a supersonic spacecraft would experience prior to landing. The sled tests will allow the Low-Density Supersonic Decelerator Project, or LDSD, to test inflatable and parachute decelerators to slow spacecraft prior to landing and allow NASA to increase landed payload masses, improve landing accuracy and increase the altitude of safe landing-sites. These new devices represent the first steps on the technology pathway to land humans, habitats and return rockets safely on Mars or other destinations. This test series is led by the Jet Propulsion Laboratory in Pasadena, Calif., and conducted at the U.S. Naval Air Weapons Station at China Lake, Calif. LDSD is one of nine missions managed by NASA's Marshall Space Flight Center's Technology Demonstration Missions Program for NASA’s Office of the Chief Technologist in Washington.

LDSD: NASA's Flying Saucer Today is World UFO Day, and if you saw a "flying saucer" a couple weeks ago in the skies over Hawaii, don't worry, it wasn't a UFO, it was a test flight of NASA's next generation spacecraft. The Low-Density Supersonic Decelerator (LDSD) conducted its second test on June 8th, splashing down in the Pacific Ocean. The inflatable re-entry vehicle’s purpose is to aid in the eventual safe landing of larger payloads on the Martian surface. As part of the June 8th's test flight -- which launched at 7:45am HST, the LDSD was floated to a height of 120,000 feet (37 kilometers) by a giant balloon before it successfully separated as planned at 11:35am HST. Soon after separating, an onboard rocket took the craft to an altitude of 180,000 feet, where the Supersonic Inflatable Aerodynamic Decelerator (SIAD) -- the first braking technology of its kind -- deployed near Mach 3 speeds at 11:37am. "Developing and demonstrating entry, descent and landing technologies such as supersonic decelerators is critical to enabling our journey to Mars," said Steve Jurczyk, associate administrator for the Space Technology Mission Directorate at NASA Headquarters in Washington. "The technologies tested on LDSD are giving us data and insight into the capabilities we’ll need to land more mass than we currently can on Mars, which will enable more capable robotic missions, as well as human precursor missions to the Red Planet." Only fourteen seconds after SIAD inflation, a 100 foot wide parachute -- the largest supersonic parachute ever flown -- was released. This parachute is more than double the surface area of the parachute utilized to slow down Curiosity's Martian descent in August of 2012. However, the parachute began to generate large amounts of drag, and ultimately a tear appeared in the canopy at about the time it was fully inflated. "Early indications are that we got what we came for, new and actionable data on our parachute design," said Mark Adler, project manager for LDSD at NASA's Jet Propulsion Laboratory. "At present, our data is in the form of low-resolution video and some other nuggets of data which were downlinked in real-time. But this will soon change when our test vehicle makes port, and we have the opportunity to inspect the ultra-high resolution, high-speed imagery and other comprehensive information carried in the memory cards on board our saucer."
