West Coast: If you have clear skies, you might see our #DARTmission & its @SpaceX rocket in the sky tonight. Our Double Asteroid Redirection Test is set to launch at 10:21 p.m. PT from @SLDelta30 in California. This chart shows when it may be visible. Let us know if you spot it! https://t.co/Cs9WLQCKth — PolitiTweet.org
