The Low-Density Supersonic Decelerator Project will test inflatable decelerators and advanced parachutes in a series of rocket sled, wind tunnel, and rocket-powered flight tests to slow spacecraft prior to landing. This technology will allow NASA to increase landed payload masses, improve landing accuracy and increase the altitude of safe landing-sites. (NASA).

NASA has completed three key milestones in its development of new atmospheric deceleration technologies to support exploration missions across the solar system.

The Low-Density Supersonic Decelerator project, which is developing technologies to use atmospheric drag to dramatically slow a vehicle as it penetrates the skies over worlds beyond our own, completed three successful rocket sled tests of the “SIAD-R,” a Supersonic Inflatable Aerodynamic Decelerator, the first of three innovative deceleration systems now in development.
