In case you are planning to watch tonight's OSIRIS-reX launch, I am now watching the live feed, and at 5:20 they announced T minus 1 hour 30 minutes. So the earlier report I had heard about the launch time was either wrong, or they have moved the launch up. Anyway, launch is now apparently at 6:50, not 7:05. Wouldn't want anyone to miss the best part!
