  Hey,
  
  Good question, you’ve been asking a lot of those 🙂 So to track asteroids (meteorites are only space rocks that have hit the ground) in space we use telescopes and we can calculate the orbits of them like we have with Earth to know where they will be at any given time.
  
  Have you seen a shooting star before? because if you have they are rocks falling from space. We can use a cameras to track the fireball and work out where it will land. These are called fireball networks and help us find the meteorites when they have landed. I am hoping to go to Spain to work with someone I know on their fireball network. Basically we see a shooting star, jump in jeeps and work out where it will land as we drive.
  
  But lots of meteorites are found by chance in deserts such as the Sahara and the Antarctic. We didn’t track them as they are likely to have fallen where we don’t have cameras or a long time ago before cameras.
