About This Lesson
The Cosmic Ray Telescope for the Effects of Radiation, or CRaTER, is a shoebox-sized instrument on the Lunar Reconnaissance Orbiter. LRO is a NASA spacecraft that has been circling the moon since June 2009. The purpose of CRaTER is to detect cosmic rays that can be harmful to an astronaut's body.
Using the downloadable pages, students can make a comic book that explains cosmic rays, the danger of cosmic rays and how CRaTER works.
