Space Travels in Geology: Io: A Different Kind of Hell
With more than 400 erupting volcanoes, Jupiter's closest moon is the most geologically active body in our solar system. Despite all the hot lava, however, Io is deathly cold — not a site you would want to visit on your summer vacation.
Mary Caperton Morton



Venturing to Venus
Scientists suspect that Earth and Venus formed from the same parent material 4.5 billion years ago. They know that the two planets are similar in size, makeup and distance from the sun. But what they don’t know is why Earth developed into a planet able to support life while Venus degenerated into a scorching wasteland. New missions should help scientists get to the bottom of this mystery.
Erin Wayman

Destination Moon
When we last set foot on the moon in 1972, no one imagined it would be more than three decades before we would return. Plans to return humans to the moon are under way — but will the moon be a stepping stone to Mars or a destination all its own?

Rocks: Not Just for Jocks Anymore Print Exclusive

California’s Battle over Greenhouse Gas Emissions Standards
Late last year, the Environmental Protection Agency denied a request by California to adopt its own emissions standards for new automobiles. California appealed, and now the battle is back in court.

A COMMENT ON ...
Resource Nationalization: A Smaller Piece of the Pie
Soaring energy prices and record-breaking profits have emboldened some countries to “reconsider” their relationships with foreign oil companies operating within their borders. It’s a short-term perspective.
Benjamin A. Eisterhold and Michael E. Webber
