NASA Group to Analyze New Vehicle-Descent Technologies

NASA technologists will get a opportunity next summer time to experience the good old days when Organization technical engineers would connect space-age devices to rockets just to see if the gadgets proved helpful.

In what will be the first of four high-altitude enhance routes to begin in the summertime season of 2013, technologists at NASA's Jet Space Clinical (JPL) in Pasadena, Calif., and Wallops Journey Ability in Wallops Isle, Va., are planning to evaluate new deceleration gadgets that could substitute present nice technological innovation for getting ever-larger payloads at higher levels on Mars.

NASA is using a sequence of explode snowmobile assessments at the U.S. Naval Air Weaponry Place at Chinese suppliers Pond, Calif., in planning for full-up assessments of the Low-Density Supersonic Decelerator Venture, or LDSD. The project is examining water and parachute decelerators to slowly spacecraft prior to getting and allow NASA to enhance arrived payload public, enhance getting precision and enhance the elevation of secure landing-sites.

NASA hasn't examined deceleration technological innovation supersonically since 1972 when it performed four high-altitude assessments of a supersonic parachute used during the Viking program. "We’ve been trapped with that style ever since," said Level Adler, NASA’s Low-Density Supersonic Decelerator (LDSD) program lead. NASA will use the same technological innovation again this year when it provides the Fascination rover to Mars.

However, planetary landers of the next day will require much bigger move gadgets than any now in use. "What we need is new technological innovation to slowly bigger, bulkier landers from the supersonic connections of environmental use of subsonic ground-approach connections," Adler said.

The LDSD program is targeted at providing NASA a new and enhanced ability. Financed by NASA’s Area Technology Program, the JPL-led team programs to perform full-scale, stratospheric assessments of three possibly cutting-edge technological innovation. The aim is to increase their technology-readiness levels to about six, which means they could be used in a plane project, perhaps as early as 2018.

The first two are supersonic water decelerators, large stress boats that fill around an access automobile and slowly it from Mach 3.5 or quicker to about Mach 2. One of these water gadgets actions nearly 20 toes across (six meters), the other nearly 26 toes (eight meters). The third technological innovation is a 110-foot (33.5-meter) parachute to further slowly the access automobile from Mach 2 to subsonic connections needed for a secure getting. All three would be the biggest gadgets of their kind ever traveled at connections several times greater than the rate of audio.

The style involves the group to connect the test automobile outfitted with the decelerator and parachute to a Wallops-provided high-altitude enhance. Once the enhance gets to an elevation of about 22 kilometers (36 kilometers) above Global exterior, the explode would flame its applications and bring check automobile to Martian environmental densities at an elevation of 31 kilometers (50 kilometers) at Mach 4. There, check automobile would set up the supersonic decelerator, followed by the parachute.

Perfect Wedding of Capabilities

The project harnesses the strong points of both companies, said Scott Schaire, Wallops LDSD performing project administrator. While NASA JPL and its companies are creating check automobile, decelerators, and parachute, NASA Wallops is accountable for enhance functions, enhance instrumentation, and other functions associated with enhance releases.

One considerable NASA Wallops-provided technological innovation is an entirely new enhance release program — an attempt Schaire's team started particularly for the supersonic assessments. With this new program, check automobile will be revoked from a straight, 80-foot structure. Its job is avoiding check automobile from reaching the earth as the enhance starts to increase off. A customized equipment that appears like a farm-irrigation program will help specialists lay out the enhance and a new reel automobile will hold the enhance until release.
