Won&#x27;t happen.  Nasa will never do a purely propulsive landing of such a craft.<p>Parachutes cannot act as backup to a rocket-powered landing.  Chutes need speed+altitude to deploy.  If the rockets fail 25 meters above the ground, chutes won&#x27;t save anything.  If the craft has chutes+people on board, they will be deployed long before touchdown.  Better out than in.<p>The only fully propulsive landing option, with humans on board, would be to have a second set of engines ready to perform what in an airplane would be called a zero-zero ejection maneuver[1].  This would see the craft reverse course, ascending rapidly to a trajectory where the chutes have time&#x2F;energy enough to properly deploy.  It would basically be a launch escape system.  To keep that, and the chutes, and the descent engines ... just use the chutes.  It isn&#x27;t saving much money not deploying them as they will probably require repacking for inspection either way.<p>[1]A zero-zero ejection seat is one that can save a pilot from a craft parked on the runway, at zero-speed and zero altitude.  Older seats required altitude and&#x2F;or speed.  But the dragon would be descending, with a negative alt&#x2F;speed, so I guess this would be a sub-zero-zero ejection.  A descent escape maneuver?
