Using laser beam for communicating with distant spacecraft

The feasibility of using a laser beam for communicating with a distant spacecraft will be tested by Laser Link from Tenerife to SMART-1.

SMART-1 is the first of ESA’s Small Missions for Advanced Research in Technology. It will head for the Moon using solar-electric propulsion and carrying a battery of miniaturised instruments. As well as testing new technology, SMART-1 will make the first comprehensive inventory of key chemical elements in the lunar surface. It will also investigate the theory that the Moon was formed following the violent collision of a smaller planet with Earth, four and a half thousand million years ago.
