On july 27th at 6:30pm pdt the beta ended, closed, and is no longer available to play. The really important thing is though, that hopefully we'll see you in September playing the full game.
Pardon our dust! We are pushing an update to Destiny that will return users to the title screen after they complete their current activity. You will be able to sign back in immediately after returning to the title screen.
