NASA's asteroid deflection test explained
Daily MailSmashing a spacecraft into an asteroid in a bid to throw it off course may evoke memories of a Hollywood disaster movie such as Armageddon or Deep Impact. It is the US space agency's first ever attempt at such a mission and will involve a spacecraft crashing into an asteroid 6.8 million miles from Earth at 15,000mph in two weeks' time. Brace for impact: NASA's first ever 'planetary defence' spacecraft – sent to deflect an asteroid 6.8 million miles from Earth – is set to hit its target on Monday, September 26. The graphic above shows how the mission will work The spacecraft has captured images of its target double-asteroid system, which includes the asteroid it will crash into, called Dimorphos, the asteroid moonlet of Didymos The Double Asteroid Redirection Test was launched last November ahead of a year-long journey to crash into the small asteroid Dimorphos, which orbits a larger one called Didymos WHAT IS THE NASA DART MISSION? They then devise a plan to have a deep core oiler driller train a group of asteroids to drill a hole into the space rock so they can detonate a nuclear bomb to split the asteroid in half — the same idea as in Deep Impact, but not one at play with DART With Dimorphos, a small nudge 'would add up to a big change in its future position, and then the asteroid and the Earth wouldn't be on a collision course,' NASA said.
