Landing rovers and helicopters on Mars is a challenge. It’s an even bigger challenge when you don’t have enough information about how the parachutes are
NASA Armstrong Public Affairs SpecialistCoby Asselin, from left, Adam Curry, and L. J. Hantsche set up the data acquisition systems used during testing of a senor to determine parachute canopy material strength at NASA’s Armstrong Flight Research Center in Edwards, California. The sensor tests seek to quantify the limits of the material to improve computer models and make more reliable supersonic parachutes. enduring strain during the descent to the surface.
“We are aiming to prove which sensors will work for determining the strain on parachute canopy material without compromising it,” said L.J. Hantsche, project manager. NASA’s Space Technology Mission Directorate funds the team’s work through the Early Career Initiative project. The test team prepares a test fixture with a nylon fabric sample at NASA’s Armstrong Flight Research Center in Edwards, California. The fabric in the test fixture forms a bubble when pressure is applied to the silicone bladder underneath. A similar test can be performed with a sensor on the fabric to verify the sensor will work when stretched in three dimensions.
This stage of testing was accomplished in partnership with NASA’s Jet Propulsion Laboratory in Pasadena, California. A high-speed version of this test, which simulates the speed of the parachute deployment, was performed at NASA’s Glenn Research Center in Cleveland.
