Quote from the facebook update:
"If you are playing in the Destiny Alpha, please join us for one, final, explosive mission tonight at 6PM PST. This is the last chance for us to prepare for the Destiny Beta. We look forward to seeing you in the Tower, in the Crucible, and in the wild. One final effort is all that remains!"
