Adapting Earth Skills to Space

As we migrate out into space, many of our jobs and their attending skills will need to change. Some skills that have been needed on Earth may dissipate and new ones will need to be cultivated for the space environment. Changes in gravity and atmosphere will be among the driving factors. OUTDOOR VS INDOOR Skills […]

Navigation in the Asteroid Belt

Navigation requires time and position data and the ability to calculate and plot a course. Historically, we have used “fixed” points like stars and buoys and beacons and landmarks and we plotted courses to fixed destinations. More recently we have learned to use a network of Global Positioning System (GPS) satellites. The satellites move constantly […]

Building Space Habitats

While we may use the Moon and Mars as stepping stones in our migration into space, the real end target will be the asteroid belt. Once we have spent the resources needed to accomplish the steep climb out of a planetary gravity well, it makes sense to stay there. The asteroid belt suits this purpose. […]

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 […]

Animation of 100,000 Asteroids

Asteroids can be identified in SDSS imaging because they change position during the course of an 8-minute exposure with the SDSS camera. The SDSS has identified and measured colors of more than 100,000 asteroids and other Solar System minor objects. The video to the left shows the orbits of many of the asteroids that the […]

Some of Us Need to Get Off This Planet

There are too many ways for the existence of our entire species to be threatened without good recourse as long as we’re all on a single planet. We need to diversify our locations and provide alternative responses for survival. An asteroid strike, a gamma ray bombardment, a super volcano, an accident from bio-genetic tinkering, a […]

Gamma Spectroscopy for Asteroid Mining

Asteroids are constantly awash in a bath of cosmic rays which produce neutron showers when they collide with atoms in the material of the asteroids. The neutrons in turn collide with other particles, giving off gamma rays in the process. Spectrum analysis of the gamma radiation can determine which elements were involved in the collisions […]

Space Habi-Craft

[artist conception from deepspaceindustries.com] The drawing above shows how a habitat-craft wheel can be built using materials extracted from an asteroid. The most likely configuration for both space dwellings and space craft is a rotating wheel. The rotation of the wheel provides an outward force that replaces gravity, which is essential for long term health. […]

Asteropolis Cities in Space

An Asteropolis city is a giant rotating wheel parked in an orbit somewhere in the asteroid belt and providing a safe habitat for several million people. In space, clusters of these giant cities will form the beginning of the future of humanity, like stepping stones toward distant stars. And new concepts of freedom and commerce […]
