Elon Musk, Jeff Bezos, Sam Altman and others have pledged support for orbital data centers, but the idea faces many challenges, including withstanding radiation in space and the costs of getting machines beyond the atmosphere. Yet as data centers grapple with terrestrial opposition and physical limits, having computing facilities float above Earth has become increasingly attractive. To be clear, Google is not sending up a full data center — only an experimental precursor to one. MVP contains four specialized computer chips called “tensor processing units,” which have the computing power of one server in a data center. The satellite’s solar panels will supply only about one kilowatt of power — roughly the amount needed to run a hair dryer — to the chips.
