FireBear 0 #1 November 15, 2017 NASA's Mars 2020 Mission Performs First Supersonic Parachute Test The first flight of an advanced supersonic parachute system for Mars 2020—NASA’s next Mars rover. This video is narrated by Ian Clark, the test's technical lead from NASA's Jet Propulsion Laboratory in Pasadena, California. The test took place on Oct. 4, 2017, at NASA's Wallops Flight Facility, Virginia. At the moment of full inflation, the parachute is going 1.8 times the speed of sound or nearly 1,300 miles an hour, and generating nearly 35,000 pounds of drag force—drag that would be necessary to help slow a payload down as it was entering the Martian atmosphere. This is the first of several tests in support of NASA’s Mars 2020 mission. https://youtu.be/mTAbj8aRVvg?list=PLTiv_XWHnOZpzQKYC6nLf6M9AuBbng_O8 Quote Share this post Link to post Share on other sites

quade 4 #4 November 16, 2017 davenuk half a second inflation... brisk.. Understand the atmosphere on Mars (and being simulated here) is -very- thin. What that means is, even though the inflation rate is rapid by Earth standards, it's not particularly jerky (yes, a change in velocity is called jerk).quade - The World's Most Boring Skydiver Quote Share this post Link to post Share on other sites

What that means is, even though the inflation rate is rapid by Earth standards, it's not particularly jerky (yes, a change in velocity is called jerk). 35,000 pounds of drag force would likely cause a bit of a jerk on anything we could send to Mars at this point in time. I think that is what they said the parachute generated under the test conditions.Instructor quote, “What's weird is that you're older than my dad!” Quote Share this post Link to post Share on other sites
