How an asteroid could wipe out life on Earth – and what we’re doing about it

The Independent  

Even as the asteroid hurtled towards Earth, we were arguing. Knowing all the information about the asteroid, including the risk it posed, would require quick action and substantial funding – but it would be hard to convince those in power to spend time and money on a threat that couldn’t be quantified. “Many stakeholders expressed that they would want as much information about the asteroid as soon as possible but expressed skepticism that funding would be forthcoming to obtain such information without more definitive knowledge of the risk,” Nasa’s report on the test notes. The most famous and successful of them was Nasa’s Double Asteroid Redirection Test, or DART, a $330 million mission that in 2022 collided with Dimorphos, a moon around the asteroid Didymos. They didn’t pose any kind of threat to Earth, but the test allowed scientists to see whether we might be able to change the path of an asteroid that did – and it was successful.
