Deflecting an Asteroid Threat

Movies like to portray the ultimate defense against an asteroid threatening life on planet Earth as a nuclear weapon tipped missile. This makes little sense. We think of our Inter Continental Ballistic Missiles (ICBM) as being long range because they are compared to most of our other weapon systems. But in the sense of interplanetary […]

A Mass Migration into Space

A great migration into space is beginning. As space exploration evolves from the control of national space programs to commercial enterprise, the nature of the effort is changing. There is a German word, “zugunruhe”, that describes anxious, restless movement, often associated with migration. When a change comes, some species feel the urge to migrate. They […]

Asteroids of Potential Hazard to Earth

Asteroids of Potential Hazard to Earth

Orbits of Potentially Hazardous Asteroids – [nasa.gov] This graphic shows the orbits of all the known Potentially Hazardous Asteroids (PHAs), numbering over 1,400 as of early 2013. These are the asteroids considered hazardous because they are fairly large (at least 460 feet or 140 meters in size), and because they follow orbits that pass close […]

Asteroid Belt Economy

University of Alabama graduate students ponder building necessary infrastructure for space exploration. There are two missing pieces in their thinking: Instead of building outposts on craggy, randomly shaped rocks, it makes more sense to fabricate whatever you want (a space habitat) and spin it to create internal gravity-like force. With very cheap energy, plentiful building […]

Coronal Mass Ejection

On Sunday, August 1, 2010, the side of the Sun facing the Earth erupted with a “coronal mass ejection” and a lot of other activity. This is a when a huge bubble of gas throws a large blob of plasma out into space and in this case it’s streaming toward Earth at a very high […]

Asteroid Ice

Astronomers have detected the spectrum signature of ice on an asteroid called 24 Themis in the main belt. They believe the thin coating of frost on the 200 kilometer wide rock is constantly being evaporated by the Sun and then replenished from an interior supply deep inside the rock. Astronomers Find Water On Asteroid’s Surface […]

Government in Space

Governments are organized for the purpose of common defense and the well being of the group. In a nomadic tribe, there is little to defend in the way of territory, structures or possessions, so the form of government is usually minimal and often casual. The tribe can simply pick up and move on to escape […]

Commerce in Space

Commerce in space will be driven by the demands of exchange and the economic factors involved. Raw Materials: Air and water are likely to be in high demand and even if they become somewhat abundant, will always remain treasured for their inherent importance. Food will be mostly manufactured locally, assuming you have the raw materials […]

Space Vehicles

Space vehicles that are designed primarily for space travel alone will be unlike craft that are designed for navigating in an atmosphere. There is no need to consider aerodynamics in space or stress related to strong gravitational fields. Instead, they need to have strong hull integrity and if they are designed to rotate to create […]

Economics in Space

Before attempting to predict how commerce will occur in space or how government will be designed to regulate it, it is important to understand how the basic economic factors will be changed. Comparison of Economic Elements On Earth ELEMENT In Space free AIR expensive cheap WATER expensive moderate FOOD moderate expensive ENERGY cheap expensive TERRITORY […]
