A giant satellite is causing some stir, because it would be responsible for light pollution, it is the Blue Walker 3 satellite. Decryption with journalist Nicolas Chateauneuf on the set of 20 Heures, Friday October 20.
The Blue Walker 3 satellite’s mission is to provide broadband to mobile phones. Its antenna is huge. A light that upsets the astronauts. It is as strong as that of the stars, much brighter. Its antenna is so powerful that it reflects sunlight. And the light trail from this satellite worries and disrupts the radio telescopes which probe distant areas of the universe, but also those responsible for detecting asteroids. “Its designers want to launch 90”indicates Nicolas Chateauneuf, on the set of 20 Heures, Friday October 20.
Space gold rush
Problem: space is more and more crowded and there is no arbiter: around 500 km altitude, in low orbit, there are 5,000 satellites from Elon Musk, and 600 satellites from One Web, but none presence ensures the law of the road. We are witnessing a space gold rush.
