On our way! 55 minutes into its flight, the #DARTMission spacecraft has separated from the @SpaceX Falcon 9 second stage, and will soon begin to orient itself toward the Sun. https://t.co/hI6NoQ11zw — PolitiTweet.org

@Wardor82 @SpaceX Simulations are great (and we run _a lot_ of them), but there's nothing like seeing your concept work in real life. While there are no known asteroid hazards to Earth for at least 100 years, we want to test the kinetic impactor technique just in case the need arises. — PolitiTweet.org

@Kaiisnice @SpaceX @NASAJPL You can rest easy. We're going to hit a small moonlet the size of a football stadium with a spacecraft the size of a vending machine. We hope to change its orbit a tiny bit, but it will stay in orbit around its parent asteroid, which is not a hazard to Earth. — PolitiTweet.org

@stretchdogg @SLDelta30 This is only the second interplanetary launch ever from the West Coast of the United States. (The first was @NASAInSight.) A rare treat to be able to see it in person, and we were happy to share it with you! — PolitiTweet.org

Asteroid Dimorphos: we're coming for you! Riding a @SpaceX Falcon 9 rocket, our #DARTMission blasted off at 1:21am EST (06:21 UTC), launching the world's first mission to test asteroid-deflecting technology. https://t.co/FRj1hMyzgH — PolitiTweet.org

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

The upcoming movie “Don’t Look Up” is a fictional story about a doomsday comet, but our #DARTMission is a real spacecraft that will deflect a non-threatening asteroid as a test of #PlanetaryDefense. Hear from director Adam McKay as he compares the two. https://t.co/bqiyWOKMPQ — PolitiTweet.org

@dickeygreen DART will set a course to impact the small moonlet asteroid Dimorphos in fall 2022. Its companion CubeSat will watch the final maneuver, while ground-based telescopes here on Earth will calculate how effective it was at changing the asteroid's orbit.

@e_seife You and your daughter can rest easy. There are no known asteroid threats for at least the next 100 years. But just in case, we're keeping our eyes on the skies, and testing the tech we'd need to move an asteroid (if the need ever did arise). https://t.co/hiAfCp3qrp — PolitiTweet.org

@freshmootz @JHUAPL @SpaceX @SLDelta30 #DARTMission will crash into Dimorphos, a small asteroid more than 6 million miles from Earth, to nudge it very slightly. Dimorphos does *not* pose a threat to Earth, but what we learn from DART could help us deflect any asteroids that threaten our home planet in the future! — PolitiTweet.org

@iKamalVeda @ImAnuraagSharma Rest assured! #DARTMission's target, Dimorphos, is actually orbiting a larger asteroid (named Didymos), and DART's impact won't be strong enough to break Dimorphos from its orbit and move it towards Earth. — PolitiTweet.org

@C7nsin05clt6mF0 Thanks for asking! Our expert answered at 07:40 here: DART can't change the orbit in a way that would send the asteroid closer to Earth. It will slightly change the speed of the smaller asteroid, which will stay in orbit around the larger asteroid: https://t.co/WfV4SKLI7A — PolitiTweet.org
