What Elon Musk's 42,000 Starlink satellites could do for — and to — planet Earth

⁣Over the next few decades, Elon Musk is hoping to send 42,000 satellites to space.
He is hoping those satellites bring high-speed internet to every corner of the world— from the rainforest to Antarctica.
But experts worry that the number of satellites could have a major impact on our planet.
Their bright reflections are already blocking the views of astronomers looking for deadly asteroids. If enough of them become disabled, which is already happening, they could also block off space travel for decades.
