The ngo is meant to past 5 days earlier the Dragon unit capsule splashes down disconnected the seashore of Florida. During its clip successful space, the unit volition transportation retired astir 30 subject experimentation and probe projects, chiefly to assistance recognize the effects of radiation connected astronaut health.
