For Beginners:

Citizen Scientist (musician and overall very cool guy), John Larsen, initiated this new field of science and wrote a great book on the subject called In Search of Stardust: Amazing Micrometeorites and Their Terrestrial Imposters. John has encouraged people to go out and to findMeteorite not seen to fall, but recovered at some later date. For example, many finds from Antarctica fell 10,000 to 700,000 years ago. their own micrometeorites using just a few simple tools and a technique he outlines on his Project Stardust Facebook page and in his other book On the Trail of Stardust: The Guide to Finding Micrometeorites: Tools, Techniques, and Identification. To learn more about how John began his journey, you can read an excellent article here. Yes, you too may find a micrometeoriteMeteorite so small that it falls to Earth essentially unchanged from how it existed in space. If a meteoroid entering the Earth's atmosphere is sufficiently small (generally less than 10-6 m), it will be slowed by collisions with molecules in the upper atmosphere to a degree where ablation does not on your roof!
