At the start of the month, Elon Musk announced that two of his companies - SpaceX and xAI - were merging, and would jointly launch a constellation of 1 million satellites to operate as orbital data centers. Musk's reputation might suggest otherwise, but according to experts, such a plan isn't a complete fantasy. However, if executed at the scale suggested, some of them believe it would have devastating effects on the environment and the sustainability of low Earth Earth orbit.
Google on Tuesday announced a new moonshot - launching constellations of solar-powered satellites packed to the gills with its home-grown tensor processing units (TPUs) to form orbital AI datacenters. "In the future, space may be the best place to scale AI compute," Google executives wrote in a blog post, in which they explain that solar panels can be eight times more efficient in space than on Earth, and can produce power continuously.
