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.

Cool. Wonder if Strong was involved?

I hold it true, whate'er befall;
I feel it, when I sorrow most;
'Tis better to have loved and lost
Than never to have loved at all.

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).

>(yes, a change in velocity is called jerk).

A change in velocity is called acceleration. A change in acceleration is called jerk.

Fair enough.

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.
