NASA's Mars 2020 Mission Performs First Supersonic Parachute Test
"It is quite a ride," said Ian Clark, the test's technical lead from NASA's Jet Propulsion Laboratory in Pasadena, California. "The imagery of our first parachute inflation is almost as breathtaking to behold as it is scientifically significant. For the first time, we get to see what it would look like to be in a spacecraft hurtling towards the Red Planet, unfurling its parachute."
A 58-foot-tall (17.7-meter) Black Brant IX sounding rocket launched from Wallops on Oct. 4 for this evaluation of the ASPIRE payload performance. The payload is a bullet-nosed, cylindrical structure holding a supersonic parachute, the parachute's deployment mechanism, and the test's high-definition instrumentation -- including cameras -- to record data.
The rocket carried the payload as high as about 32 miles (51 kilometers). Forty-two seconds later, at an altitude of 26 miles (42 kilometers) and a velocity of 1.8 times the speed of sound, the test conditions were met and the Mars parachute successfully deployed. Thirty-five minutes after launch, ASPIRE splashed down in the Atlantic Ocean about 34 miles (54 kilometers) southeast of Wallops Island.
"Everything went according to plan or better than planned," said Clark. "We not only proved that we could get our payload to the correct altitude and velocity conditions to best mimic a parachute deployment in the Martian atmosphere, but as an added bonus, we got to see our parachute in action as well."
The parachute tested during this first flight was almost an exact copy of the parachute used to land NASA's Mars Science Laboratory successfully on the Red Planet in 2012. Future tests will evaluate the performance of a strengthened parachute that could also be used in future Mars missions. The Mars 2020 team will use data from these tests to finalize the design for its mission.
The next ASPIRE test is planned for February 2018.
The Mars 2020 project's parachute-testing series, ASPIRE, is managed by the Jet Propulsion Laboratory, with support from NASA's Langley Research Center, Hampton, Virginia, and NASA's Ames Research Center, Mountain View, California, for NASA's Space Science Mission Directorate. NASA's Sounding Rocket Program is based at the agency's Wallops Flight Facility. Orbital ATK provides mission planning, engineering services and field operations through the NASA Sounding Rocket Operations Contract. NASA's Heliophysics Division manages the sounding-rocket program for the agency.
