I always get excited at launches, but this time I felt more emotional than I thought as I realized I was watching Atlantis soar into the sky for for the final time. This will be a great mission to watch and no doubt the world will be watching too. Keep it tuned to Spacers for updates as the mission progresses.

Thank you for loving spaceflight.
