Dragon ready to head to the ISS
Space X has been given the green light by NASA for its first mission to the ISS. This initial mission will see no cargo or personnel on board the Dragon capsule. The Dragon spacecraft will take four days conducting tests in orbit before it attempts to dock with the ISS including making loops around the ISS at varying distances.
During those days prior to attempting a docking procedure, the mission can fail if NASA feels communications or operation issues are noted with capsule. If the mission comes off without a hitch, the next time the Dragon capsule goes up it could be carrying cargo and in the future it could bring up to seven astronauts the ISS.
