Radar helps us explore our solar system

The rapid development of radar brought about by world war provided many opportunities for peacetime exploitation. From air-traffic control and police radar traps to medical scanning techniques, but perhaps the most interesting use of radar is to help us explore our solar system in the new science of Radar Astronomy. Radar astronomy has grown from the early Earth-based mapping of our nearest celestial neighbours to modern scientific radar analysis of distant moons by remote space probes.

On the 21st December there is a conjunction of Saturn and Jupiter – they will appear to be very close together in the sky.

In the video below, Paul Whiting explains the development of Radar Astronomy.
