Asteroid Smashing Looks Like Nothing You Ever Imagined

By Scott Manley. 

Response: Wouldn't firing an asteroid that is loosely connected like shooting a bullet into a lake? The energy would simply be absorbed in the sand (liquid-like solid). If there is no measurable change in orbit, that would be why.

Sending ice into space

The key to cheap space is to get ice into orbit. Start with making steam in the middle if the ocean and sending it up a pipe to where it condenses. Next to the pipe, have a track for containers plus a power line system and solar. 

At the point of condensation, make lox and hydrogen chilled for loaded containers of ice and propellant and load it into a magnetic catapult, launching it toward a depot in orbit for processing for more fuel and for orbital good production.

Missions needing artificial gravity

Before going beyond Luna or for staying in Earth orbit working in a tourist hotel, artificial gravity using centrifugal force must be investigated and developed to counter possible bad effects on balance. Bigger rings at lower G may be our best bet for now.

The best first mission to Mars and any mission to Venus or a gas or ice giant should be a ringed station. Call it Orbital JPL. Such stations can do measurements and send probes into atmosphere or, for Mars and Luna, do what Gateway is planned to do - but with gravity and shielding.

If we cannot make this work, there is no reason to continue with manned exploration. Even unmanned missions would be a waste of time. A large station in Jovian orbit, however, would be worth the effort.

Artificial Gravity Test Plan for Sierra

This system is essential for an artificial gravity test. Take four modules, two at each end, of 2 adjustable arms attached to a center flywheel, power storage (and possibly a nuclear power source) and an inflatable control module. Test various rotation  speeds diameters to see what humans can tolerate. Next, add arms and modules for a long term test in a connected ring.

The initial test could be launched on SLS or Falcon Heavy. Until this test is passed, any exploration beyond the moon is folly.
