  • Ian Clark, LDSD principal investigator at JPL
To participate by phone, reporters must contact Kim Newton by email at kimberly.d.newton@nasa.gov or 256-653-5173 no later than 5 a.m. Tuesday.
Audio of the teleconference will be streamed live at:

NASA’s Low-Density Supersonic Decelerator test vehicle
NASA’s Low-Density Supersonic Decelerator test vehicle begins its ascent to 180,000 feet aboard a helium-filled balloon. It launched from the U.S. Navy’s Pacific Missile Range Facility on Kauai, Hawaii, to test entry, descent and landing technologies NASA will need to land large payloads on Mars and other distant planets.

LDSD launched at 7:45 a.m. HST (1:45 p.m. EDT) from the U.S. Navy’s Pacific Missile Range Facility using a large scientific balloon. After it was carried to an altitude of nearly 120,000 feet, the LDSD test vehicle separated from the balloon. An on-board rocket motor ignited and continued to carry the vehicle to nearly 180,000 feet.
Two advanced decelerator technologies – a supersonic inflatable aerodynamic decelerator and a supersonic parachute – were tested. The supersonic inflatable aerodynamic decelerator deployed and inflated. The supersonic parachute also deployed, however, it did not perform as expected. Data was obtained on the performance of both innovative braking technologies, and the teams are beginning to study the data.
The LDSD project is one of several cross-cutting technologies NASA's Space Technology Mission Directorate is developing to advance the critical technologies required to enable future exploration missions to destinations beyond low-Earth orbit, including an asteroid, Mars and beyond.
LDSD testing is conducted through NASA's Technology Demonstrations Missions program, based at the agency’s Marshall Space Flight Center in Huntsville, Alabama, with technology development work and testing led by JPL. NASA's Wallops Flight Facility in Virginia coordinated range and safety support with the Pacific Missile Range Facility and provided the balloon systems used to launch the LDSD test vehicle.

NASA's LDSD Project Completes Second Experimental Test Flight

NASA's Low-Density Supersonic Decelerator
NASA's Low-Density Supersonic Decelerator hangs from a launch tower at U.S. Navy's Pacific Missile Range Facility in Kauai, Hawaii. The saucer-shaped vehicle will test two devices for landing heavy payloads on Mars: an inflatable donut-shaped device and a supersonic parachute. The launch tower helps link the vehicle to a balloon; once the balloon floats up, the vehicle is released from the tower and the balloon carries it to high altitudes. The vehicle's rocket takes it to even higher altitudes, to the top of the stratosphere, where the supersonic test begins.

Engineers are poring over the data following the second experimental landing technology test of NASA's Low-Density Supersonic Decelerator (LDSD) project. The saucer-shaped LDSD craft splashed down at 11:49 a.m. HST (5:49 p.m. EDT) Monday in the Pacific Ocean off the west coast of the Hawaiian island of Kauai.
During this flight, the project team tested two decelerator technologies that could enable larger payloads to land safely on the surface of Mars, and allow access to more of the planet's surface by assisting landings at higher-altitude sites.
"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."
A high-altitude balloon carrying the LDSD test vehicle launched at 7:45 a.m. from the U.S. Navy's Pacific Missile Range Facility (PMRF) on Kauai.  As planned, at 11:35 a.m., the vehicle separated from the balloon at about 120,000 feet above the ocean. An onboard rocket motor then took the vehicle to 180,000 feet, where the first braking technology, the Supersonic Inflatable Aerodynamic Decelerator (SIAD), deployed at about Mach 3 at 11:37 a.m.
Fourteen seconds after SIAD inflation, the test vehicle's parachute was released into the supersonic slipstream, according to plan. Preliminary analysis of imagery and other data received during the test indicates the Supersonic Ringsail parachute deployed. This 100-foot-wide parachute is the largest supersonic parachute ever flown. It has more than double the area of the parachute used for the Mars Science Laboratory mission that carried the Curiosity rover to the surface of Mars. The chute began to generate large amounts of drag and 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 (JPL) in Pasadena, California. "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."
Monday’s flight test was the second for the project. During the first flight on June 28, 2014, the main goal was to demonstrate and operate the vehicle through its entire mission. That flight also carried the two LDSD braking technologies, and the SIAD worked perfectly during the first test. However, the supersonic parachute did not inflate as designed. With the data from last year's test, the LDSD team developed a new formula for this year's chute, making it stronger and more curved into its top to help it survive the initial shock of supersonic wind.
"The physics involved with LDSD is so cutting-edge we learn something profound every time we test," said Ian Clark, principal investigator for LDSD at JPL. "Going into this year's flight, I wanted to see that the parachute opened further than it did last year before it began to rupture. The limited data set we have at present indicates we may not only have gone well down the road to full inflation, but we may have achieved it.
“We also saw another successful inflation of our 20-ft SIAD and another successful deployment and inflation of our supersonic ballute (an inflatable drag device that extracts the parachute). Both of those devices have now had two great flights, and we have matured them to the point where they can be used, with confidence, on future missions,” Clark added. “We’re not just pushing the envelope. We flew a 7,000-pound test vehicle right through it."
NASA expects to make high-resolution imagery and comprehensive data from the test available to the public in about two weeks.
NASA's Space Technology Mission Directorate funds the LDSD mission, a cooperative effort led by JPL. The Technology Demonstration Mission Program at NASA's Marshall Space Flight Center in Huntsville, Alabama, manages LDSD. NASA's Wallops Flight Facility, on Wallops Island, Virginia, coordinates range and safety support with PMRF and provides the balloon systems for the LDSD test.
