Futureproof with Jonathan McCrea
Looking up into the night sky can be awe inspiring. For as long as we have walked this earth, humans beings have been able to gaze up into the darkness of night and wonder at the majesty of the cosmos, the ever-present, solitary moon or spy a shooting star. But they're not all natural entities. Some of those twinkling little dots were put there by us - and if Elon Musk has his way, there will be up to 12,000 more of them whizzing around above us in a constellation of satellites which will blanket the earth. Prof Mark McCaughrean, Senior Advisor for Science & Exploration at the European Space Agency joins Jonathan to talk about SpaceX Starlink and the race for a global internet service. As always we have all the latest science news stories and Jonathan responds to all your tweets and texts.
