Meet Tim McCoy, geologist at the National Museum of Natural History. Have you ever wondered how we study asteroids and other bodies in our solar system without sending spacecrafts to all of them? Meteorites, pieces from space that hurtle to Earth, turn out to be great sources of information. Take a meteorite-filled journey with Tim McCoy to outer space and back in time to the formation of our solar system. Prepare to be amazed at how meteorites contain the very building blocks of life on Earth.
