In 2022, NASA’s Double Asteroid Redirection Test (DART) spacecraft collided with the asteroid Dimorphos at 6.6 kilometres per second as it orbited its parent asteroid Didymos. Now, the European Space Agency (ESA) is preparing to launch its Hera probe to get a closer look at exactly how it was affected. It will launch from Cape Canaveral, Florida, on 7 October aboard a SpaceX Falcon 9 rocket and do a flyby of Mars in March next year on the way to the asteroid – but it won’t reach its final destin

Asteroid deflection experiment ☄️💥 In 2022, NASA’s Double Asteroid Redirection Test (DART) slammed an uncrewed spacecraft into an asteroid named Dimorphos – which is 160 metres across but not heading towards our planet – and changed its trajectory slightly, suggesting that we could swat a space rock away in a real emergency. Methods other than this have yet to be tested, but the success of DART was a good omen for our chances against a genuine asteroid threat Tap link to learn more: https://www

Just in case you missed yesterday's Double Asteroid Redirection Test (DART) impact, here is a sped-up version of the last five-and-a-half minutes of images from the spacecraft before it went boom. DART is a mission designed to test the kinetic impactor method of deflecting asteroids. Basically, we want to know if we can move asteroids on course for Earth by hitting them really, really hard. Yesterday's target was the asteroid moon Dimorphos. It orbits a larger asteroid named Didymos, which is vi

🚀 La missione DART (Double Asteroid Redirection Test) della NASA è stata la prima missione della storia a testare la difesa planetaria contro asteroidi potenzialmente pericolosi. Il suo obiettivo era deviare la traiettoria di un asteroide attraverso l'impatto di una sonda spaziale. 🌍 Target della missione: DART ha colpito Dimorphos, un piccolo asteroide di circa 160 metri di diametro, satellite del più grande asteroide Didymos. Questa coppia di asteroidi non rappresentava una minaccia per la T

Last night, we awarded the DART Mission Team the 2024 Michael Collins Trophy for Current Achievement. In 2022, NASA's Double Asteroid Redirection Test (DART) spacecraft collided with an asteroid and successfully changed its orbit — a technique that could be used for planetary defense if needed. #CollinsTrophy | National Air and Space Museum, Smithsonian Institution

🌍 NASA’s DART Mission & The Future of Planetary Defense 🚀 NASA’s DART mission (Double Asteroid Redirection Test) was the world’s first real test of planetary defense. In 2022, the spacecraft deliberately crashed into an asteroid called Dimorphos to see if we could change its orbit. And it worked — proving that humanity can, in fact, push an asteroid off its collision course with Earth. This is only the beginning of planetary defense. Future systems could include: Stronger impactors to deal wit

Humanity has officially tested planetary defense. NASA’s Double Asteroid Redirection Test spacecraft slammed into Dimorphos in 2022. The collision slowed the asteroid by just 11.7 micrometres per second, but that tiny change could move it 3.7 km over 10 years. In space, even the smallest push matters. #Space #NASA #AsteroidDefense #Science #SpaceNews
