Stepping Stones: Economic Analysis of Space Transportation Supplied From NEO Resources ABSTRACT The Stepping Stones economic analysis of space transportation supplied from near-Earth […]

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 […]

Fortunes in Space

Twenty trillion dollars is a lot of cash. In 1997, John Lewis calculated the rough value of the metal in asteroid 3554 Amun at $20,000,000,000,000. 3554 Amun is considered to be a “small” M-type asteroid at a diameter of 2.5 kilometers. Since the price of precious metals has inflated since 1997, it is likely worth […]

Life in the Asteroid Belt

Someday soon, humans will begin a mass emigration to the asteroid belt. The drivers for this diaspora will not be the noble quest for the exploration of space, or the expansion and survival of humanity, but rather the simple desire for more freedom.

We love to watch Hans Solo or some other pilot skilfully guide a spaceship through the clutter of an asteroid field. But in […]

The main asteroid belt, found between the orbits of Mars and Jupiter is estimated to contain many millions of small rocks and about 1-2 million rocks of a diameter of 1 kilometer or greater. 26 known asteroids have a diameter of 200 kilometers or more. There are also rocks found in all other parts of […]
