We’ve found the situation played out in films various periods: an asteroid is heading straight in the direction of the earth and it is up to a ragtag group of heroes to group up with NASA to help you save the planet. But ignore Hollywood for a second – nowadays items get quite true. NASA will take a look at its asteroid planetary protection technique, called DART, for the initially time. Here’s what to know about it and how you can enjoy it.

  • What is DART? DART is the name NASA has specified to the 1st take a look at of its asteroid planetary defense process. DART stands for Double Asteroid Redirection Test
  • How does DART do the job? Dart is a spacecraft that NASA will intentionally slam into an asteroid. The spacecraft weighs 1,340 lbs. and is traveling at close to 14,000 mph. The place agency wishes to see if the resulting kinetic energy from the crash can alter the asteroid’s trajectory just a tiny bit. 
  • But why only transform an incoming asteroid’s trajectory a tiny? Never we want to alter it a whole lot? The goal is to alter an incoming asteroid’s trajectory by a whole lot, in the long run. But if you can bump an asteroid that’s considerably out early adequate, even a minute improve in its trajectory at effect will sooner or later expand into a vast change as the asteroid continues its journey, so lacking earth.
  • Can not we just use nukes on an asteroid? We could, but mainly because of how physics performs, we almost certainly don’t will need these ability to stop an incoming asteroid. As NASA is screening these days, you just need to have some thing that could slam into an asteroid far enough out to bump it marginally off system, thus by the time it would get to earth, its path has been changed ample that it doesn’t occur near to it.
  • What asteroid is remaining hit today? It’s essentially a single of a pair that helps make up a double asteroid. The large 1 is called Didymos, which is 2,560 toes in diameter. Didymos has a more compact asteroid orbiting it referred to as Dimorphos, which is 530 feet in diameter. DART will slam into Dimorphos, and NASA will see if the effects improvements Dimorphos’s orbit at all. If it does, it is a fantastic indication this kind of planetary protection system can operate.
  • Is Didymos or Dimorphos a chance to earth? No, not at all. It is just a fantastic asteroid pair to exam DART on.
  • How can I watch the DART examination? NASA’s coverage of the DART mission will start at 6 p.m. ET/9 p.m. PT on its formal YouTube stay stream, embedded below. The precise DART effects is estimated to come about at 7:14 p.m. ET/ 10:14 p.m. PT.
