Travelers In The Night

In the journal Planetary and Space Science Dr. Kevin Cannon and his two coauthors analyze the potential of asteroid mining as a source of metals for manufacturing here on Earth as well as a repository of raw materials for space colonists.These authors find there are less precious metals in iron meteorites than was previous estimated. However there are a small number of precious metals whose concentration in asteroids is higher than any ores found on Earth. In the future Earthlings may be wearing jewelry made from asteroidal metals.
