Hydrothrusters for CubeSats

        My last blog talked about space tethers. One of the pioneer companies researching space tethers is Tethers Unlimited.

In the past few years, their focus has shifted away from space tethers and onto other space technologies that are more in demand.

We tend to think in terms of powerful rockets for our current space propulsion and maybe someday warp drives that can overcome the speed of light. But here were people talking about using long cables to move things around in space.
