Space probe to map carbon content of world’s remotest tropical forests

Revolutionary scanner to be fired into Earth orbit this month to measure effects of deforestation

Scientists are about to take part in a revolutionary mission aimed at creating detailed 3D maps of the world's remotest, densest and darkest tropical forests - from outer space. The feat will be achieved using a special radar scanner that has been fitted to a probe, named Biomass, that will be fired into the Earth's orbit later this month.

For the next five years, the 1.25-tonne spacecraft will sweep over the tropical rainforests of Africa, Asia and South America and peer through their dense 40m-high canopies to study the vegetation that lies beneath. The data collected by Biomass will then be used to create unique 3D maps of forests normally hidden from human sight.
