It was a simple mission, Princess Celestia just wanted the Mane Six to go out and look for Luna, but she was never found on the moon or any of the crater, nor caves. So Celestia get no transmission from Twilight or her friends, So she sends some other ponies to the job, and the other six finds the ship and notice that there is something else on that ship except the Mane Six.
