The InSight brake parachute opens at the supersonic speed of 1500 kilometres per hour. The initial load on deployment at an altitude of 12 kilometres is 55,600 Newton. Barely three minutes later, 1200 metres above the landing site, the probe will separate from the parachute and use its descent engines to decelerate until landing at around 20:53 CET. The picture shows the supersonic parachute at Lockheed-Martin in Denver, Colorado during a test.
