Boosted Orbital Tether - a fishing line in space!

The Boosted Orbital Tether is a less extreme version of the space elevator. A rocket is launched on a vertical trajectory to an altitude of several hundred kilometres. An orbiting mass drags a line and hook to catch the rocket and spends momentum to bring the rocket into orbit.

Let's look at the concept in more detail.

Expansion-cooled, Curved-nozzle stealth rocket

Here, we will look at a design for engines that can accelerate a spacecraft without producing detectable emissions. It is best fitted to a stealth spaceship described in 'The Hydrogen Steamer: Stealth Spaceship Concept'.
