They've been working on this for years. EM propulsion to get it up to target velocity.

It's not adequate to inject the payload into orbit given air resistance but really saves on mass and fuel consumption as they spin the mass up to speed in a vacuum.

I've sort of rooted for them for years off on the sidelines.
