Misleading info graphic regarding “impossible” speeds at Apollo parachute deployment. Several distortions in the graphic. There are two sets of parachutes, the drogue chutes, which are smaller, as appropriate for the higher velocities in the upper segments of reentry, and the Mains, which are deployed later in the sequence after velocity has been reduced by the drogues.

Additional facts glossed over by the graphic maker, the chutes are deployed by altitude switches, and initial deployment of each set of chutes is in “reefed” condition, which means the opening is tied (partially or fully) closed. This is a feature designed specifically to address the issue of very high velocity and prevent overstress of the chute. After the reefed chutes have been deployed for a specific amount of time, slowing the craft, the reefing lines are released, allowing the chute to open fully, creating a greater decelerating force. After the much smaller drogue chutes have done their work, the mains are deployed, also reefed, once again, to avoid overstress and destruction at the still high velocity. After a specific additional time at reduced area / force in the reefed condition, the Mains are “disreefed” and open to their full extent for maximum braking force for the terminal phase of the landing.

I don’t trust everything the government puts out, but the reentry is not impossible.
