Photo of a successful release test showing the sky and a red parachute deployment at apogee, cord positions, back-dropped against the reflective rocket fuel tank. The size of the parachute is an important factor when returning heavy payload that needs to remain undamaged. It can lessen the g force impact to the ground when landing and preserve the rocket constructs without damage for recycled launches.
Space1 has forayed a series of chute tests involving the ISS Pioneer. Testing is based on numerous variables such as payload weight, fuel ratios and pressurization, temperature, pressure, humidity, aerodynamics, velocity, chute dimensions and configurations. In the final analysis, the fabric chute is recyclable probably thousands of times, made from a washable rip stop nylon fabric material with polyester woven cord rope. Braided nylon shroud lines are very durable. Chute edges are machine sewn professionally and cords are 2DIA for maximum effectiveness. Overall the parachute is residual fuel resistive. The dimensions are calculated to fit the rocket's nose shroud housing.
