The Head of Remote Sensing at the National Institute of Space Research Brazil Dr. Luiz Aragao joins us on the programme. He explains how optical and thermal satellite images are delivering real time data about the Amazon rainforest fires. This means he and his team can calculate not only what is one fire but how much biodiversity has been lost and carbon released into the atmosphere. They are also analysing date from the ISS and the NASA GEDI mission and are able to recreate 3D images of the surface of the Earth before and after the fires.

The Rwandan tech scene

Gareth Mitchell visits a tech start-up hub in Kigali. He meets developers from Awesomity Lab who are currently creating e-government websites as well as apps and websites for major international companies. The company was created by a group of young IT specialists and looks just like any other start-up - creative spaces, high tables with designer chairs, blackboards covered with ambitious and 'out there' ideas. Just a few doors down Code of Africa is another tech company that is recruiting young coders and IT engineers - but not for Rwandan companies - Code of Africa is outsourcing their skills to businesses in Europe.

3D printing a moon base

50 years after man first landed on the moon, the race to return seems to be hotting up. India, Russia, USA, China and Europe all have big plans – including setting up a moon base. Reporter Jack Meegan has been to the European Space Agency in the Netherlands to find out if it would be possible to 3D print it.
