In a new thesis from the Swedish Institute of Space Physics and Umeå University, unique methods for the analysis of radar data and simulations of meteoroids in the solar system are presented. The methods have been applied
to confirm the existence of rare high-altitude meteors as well as to measure space debris from the Kosmos-1408 satellite. On November 25, Daniel Kastinen defends his doctoral thesis.

"My primary goal has been to carefully analyze radar measurements of meteors and space debris and evaluate the precision of the measurements. This is to improve further analysis and use the results together with the new dynamical simulations. The work paves the way for future research and allows cross-disciplinary studies on meteors as well as on space debris and near-Earth asteroids", says Daniel Kastinen.
Every day, 10-200 tons of material from space, consisting of dust- sized particles and larger pieces of material - meteoroids, fall into the Earth's atmosphere. These particles come from parent bodies such as comets and asteroids and thus date back to the time when the solar system was formed. When a meteoroid hits the Earth's atmosphere and burns up in the form of a meteor, the material is dispersed in the atmosphere. Most of these meteors are invisible to the eye but can be detected by radar.
