1. Elon Musk appeared to backtrack on his "Nuke Mars" idea on Wednesday, saying instead that we could use satellites equipped with solar reflectors to warm up the red planet. When he first floated the "Nuke Mars" idea, the SpaceX CEO suggested dropping nuclear weapons on Mars' poles to warm up the planet’s atmosphere with the eventual goal of making it more habitable for humans. But on Wednesday, Musk clarified that "Nuke Mars" "refers to a continuous stream of very low fallout nuclear fusion explosions above the atmosphere to create artificial suns." He also said that satellites could be used to the same effect. "Might make sense to have thousands of solar reflector satellites 🛰 to warm Mars vs artificial suns (tbd)," he tweeted. However, scientists argue that releasing Mars’ CO2 – Musk’s goal in these ideas – wouldn’t be enough to terraform the red planet. – INSIDE
