Today, @Astro_SEAL and @AstroBehnken exit the @Space_Station’s Quest airlock for the second spacewalk of their mission. They’ll install the last of a set of new lithium-ion batteries and route cables outside the orbiting lab. Watch starting at 6am ET: https://t.co/mzKW5uV4hS https://t.co/LbGVG7HZA9 — PolitiTweet.org

@Smartteaser192 @UN Yes, close encounters with planets can dramatically change the orbits of smaller comets and asteroids during close-passes. For one example, see: https://t.co/hV6Fw8Rue9 — PolitiTweet.org

@Owens_Juninho @UN @OSIRISREx Studying asteroids like Bennu help scientists understand how planets formed and how life began, as well as improve our understanding of asteroids that could impact Earth. More info: https://t.co/5cLpwxHrbz — PolitiTweet.org

NASA @NASA

@Owens_Juninho @UN Bennu only poses a very small (0.037%) total chance of impact in the future, and the @OSIRISREx mission is closely studying Bennu. — PolitiTweet.org

@sadhanathiru_ @UN Asteroid mining may be possible in the future. Some asteroids are thought to contain organic elements, and may have supplied those to the planets early in solar system history. But asteroids are not usually thought to be naturally habitable. #AsteroidDay — PolitiTweet.org

@AndarKiAwaaz @UN A second interstellar object, 2I/Borisov, was discovered in 2019. There are calculations suggesting there is always an interstellar object moving through the inner solar system, if we knew where to look! #AsteroidDay — PolitiTweet.org

NASA @NASA

@QueenEmmaHawaii @UN Objects are classified by international agreement, based on orbital and physical characteristics. An object may seem to fit more than one classification, but typically has only one official classification. https://t.co/q2hKzBaVMb #AsteroidDay — PolitiTweet.org

NASA @NASA

@Luco65 @AsteroidWatch @UN DART doesn’t detect asteroids. However, we're formulating the Near-Earth Object (NEO) Surveillance mission, which will survey the sky for NEOs in the infrared, with a goal of finding 90% of NEOs larger than 140m in diameter. #AsteroidDay — PolitiTweet.org

NASA @NASA

@YuLin_Langtso @UN To deflect larger asteroids, more massive impactors would be needed, but these, as well as other methods, like nuclear explosive devices for deflection, and gravity tractors, are possible with existing technologies, given enough time to prepare the missions. — PolitiTweet.org

NASA @NASA

@YuLin_Langtso @UN Yes, and we'll demonstrate this, on a small scale, with the DART mission to change the orbit of the satellite of the asteroid Didymos. — PolitiTweet.org

NASA @NASA

@Quantum59026601 @UN Of the near-Earth asteroids larger than 140 meters in size, there are about ⅔ of the predicted 25,000 remaining to be found. #AsteroidDay — PolitiTweet.org

@rohankumar___ @UN Commercial mining is not quite viable yet, but may be in the future. Yes, a careful economic approach would need to be taken to avoid negative effects on the market. #AsteroidDay — PolitiTweet.org

NASA @NASA

@goodendofkings @UN The key is the minimum time, ideally years to decades, to give plenty of time to launch an asteroid deflection mission, which is why discovering and tracking asteroids is critical. #AsteroidDay — PolitiTweet.org

NASA @NASA

@MackerelPhones @UN Some technologies already exist that can deflect an asteroid from colliding with Earth. Whether those technologies will be useful or not depends on the amount of warning time and the asteroid size. The more time we have, the more options we have! #AsteroidDay — PolitiTweet.org

NASA @NASA

@NicoleMHoneycut @UN The more measurements of an asteroids position we have, the better we can predict its future path. With enough data, we can predict future positions to within a few hundred km or better. #AsteroidDay — PolitiTweet.org
