On Thursday at 1pm EDT (1700 UTC), get a live preview of the #DARTMission, our first test to see if we can change the course of an asteroid. DART will crash into a small asteroid 6.5 million miles from Earth and measure the effect on its motion. Tune in: https://t.co/ttv3aZecAf https://t.co/lVkjK5uqaX — PolitiTweet.org
