AI In Space

NASA is planning to rely increasingly on artificial intelligence on missions so far away that constant communication with Earth is impossible.

Developing AI for such missions will no doubt hasten its adoption in society generally.

Eclipse

Today a total eclipse runs coast-to-coast across the United States.

Total solar eclipses are among the most awe-inspiring spectacles in nature, and the most benign.

Powering Mars

According to the engineering firm Siemens, powering a Mars colony could involve a combination of solar power, with solar panels deployed on the surface, wind farms, and batteries.

It would be a decentralized system, not dependent on any one factor.

TRAPPIST-1 and its planets may be twice as old as the Sun, a new study suggests.

That would give life plenty of time to evolve.

Perspective

Wal-Mart has announced quarterly revenues of over $123 billion.

For All Mankind

A group called For All Mankind is working to protect the six Apollo landing sites on the Moon as heritage areas.
