Ad Astra: nuclear spaceships, the edge of the solar system, and space monkeys


Some things are more art than science sometimes.

Structures anchored to geostationary orbit

“Space antennas” but what kind of signal would benefit from this design? X-Rays? Why would this not be better off in orbit? The structure sure looks a lot like a space elevator. Space elevators and geostationary orbital masses.

Falling from space

It’s hard to steer without sufficient atmospheric density. Felix Baumgartner’s jump “from space.”

High energy blasting

Antimatter nonsense. Our increasing fragility in the face of an unlucky coronal mass ejection. Protecting infrastructure both inside and increasingly outside our atmosphere.

Moon settlement

Moon surface settlements vs moon gateways vs embarking to The Moon from low Earth orbit. Awesome moon buggy chases. Pirates!

Mars settlement

Communicating with and from Mars. Interplanetary distance and comms speed. Building settlements within Martian or Lunar lava tubes.

The heliopause

Finding the “edge” of our star system. Difference in concentration of high energy particles.


Looking for signs of life around other stars. Taking pictures of black holes. Planet-sized telescopes. The absurd distances from Earth to other stars. Vegemite in Australia. Absent of evidence is not evidence of absence.

Nuclear spaceships

Project Orion. Blowing up your spaceship because it doesn’t have a nuclear bomb-ready push plate.
