"I have heard of a future possibility of mining asteroids for minerals. How would one go about finding asteroids that have important minerals?"
Content with the tag: “life and environment”
Understand how life on Earth and its planetary environment have co-evolved through geological time. Investigate the evolving relationships between Earth and its biota by integrating evidence from the geosciences and biosciences that shows how life evolved, responded to environmental change, and modified environmental conditions on a planetary scale.

NASA Predicts Non-Green Plants on Other Planets
NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems.
Green, yellow or even red-dominant plants may live on extra-solar planets, according to scientists whose two scientific papers appear in the March issue of the journal, Astrobiology. The scientists studied light absorbed and reflected by organisms on Earth, and determined that if astronomers were to look at the light given off by planets circling distant stars, they might predict that some planets have mostly non-green plants.
We can identify the strongest candidate wavelengths of light...

Coping with Contamination
Carol Stoker is the principal investigator for the Mars Analog Research and Technology Experiment (MARTE). MARTE has just begun its second field season drilling into the subsurface near the headwaters of the Río Tinto in Spain, searching for novel forms of microbial life. In a four-part interview with Astrobiology Magazine Managing Editor Henry Bortman, conducted just before Stoker left for Spain, she explained what MARTE hopes to accomplish. In this third part, Stoker described how the MARTE team avoided contaminating their drill-core samples.
Astrobiology Magazine (AM): When you drilled last year at Río Tinto,...
