SpinLaunch Raises $40 Million for Radical New Launch System

Bloomberg reports that Silicon Valley startup SpinLaunch has raised $40 million for a new approach to launching small satellites.

The company remains tight-lipped about exactly how this contraption will work, although its name gives away the basic idea. Rather than using propellants like kerosene and liquid oxygen to ignite a fire under a rocket, SpinLaunch plans to get a rocket spinning in a circle at up to 5,000 miles per hour and then let it go—more or less throwing the rocket to the edge of space, at which point it can light up and deliver objects like satellites into orbit.

SpinLaunch’s so-called kinetic energy launch system would use electricity to accelerate a projectile and help do much of the dirty work fighting through gravity and the atmosphere. In theory, this means the company could build a simpler, less expensive rocket that’s more efficient at ferrying satellites. “Some people call it a non-rocket launch,” said [founder Jonathan] Yaney. “It seems crazy. It seems fantastic. But we are actually using relatively low-tech industrial components to break this problem into manageable chunks.”

An impressive group of investors have signed on to support Yaney’s vision. The bulk of the $40 million came from Alphabet Inc.’s GV (formerly Google Ventures), Kleiner Perkins Caufield & Byers and Airbus Ventures.
