Another feature that this upgraded version of Dragon, to protect the life of crew in the event of a failure of Falcon 9, it was fitted with SuperDraco thrusters, which would push the capsule away from the rocket. Cargo Dragon, a variant of V2, will replace the current version of dragon that can only hold cargo.
