The parachute in the chapter-opener photo is, of course, meant to decelerate the payload on Mars. The wind tun- nel test gave a drag coefficient of about 1.1, based upon the projected area of the parachute. Suppose it was falling on earth and, at an altitude of 1000 m, showed a steady descent rate of about 18 mi/h. Estimate the weight of the payload.
