Can Intelligent Life Thrive in Close Quarters?
Topic: Alien Life
03/31/04
Summary: Where should SETI researchers target their hunt for other intelligent species? The answer depends in large part on whether planets orbiting dim red-dwarf, or M-class, stars can provide suitable habitats for the evolution of intelligent life.

Surviving With - and Without - Oxygen
Topic: Biosphere
03/17/04
Summary: Without oxygen, animal life on Earth would not be possible. But Earth's atmosphere wasn't always rich in oxygen. In fact, to early life, oxygen was a deadly poison. So where did the oxygen come from? And how did life survive the crisis that its arrival caused?

Mars: Goldilocks' Oasis?
Topic: Mars

Summary: Changing a rocky, dry planet into a habitat suggests terraforming on a vast scale. Pumping in greenhouse gases and raising the global temperature would have to begin a centuries-long metamorphosis.

Unreal Film-maker of Martian Reality
Topic: Mars
03/08/04
Summary: Daniel Maas is the film-maker that first brought animation to the Spirit and Opportunity rovers' launch, landing and driving.

Titan in a Test Tube
Topic: Titan
03/01/04
Summary: Saturn's largest moon, Titan, has one of the most promising chemical laboratories for producing complex organic molecules. Experiments conducted in preparation for this summer's mission to probe Titan's astmosphere have tried to simulate its cold, prebiotic soup.

Design Space, Nothing But Net
Topic: Missions

Summary: Astrobiology Magazine had the chance to talk with Dr. Vint Cerf, founding father of the internet, about his project to wire the solar system. Called the Interplanetary Internet, the study is to design a deep space communications network protocol.

View to the Edge of No-Return
Topic: Cosmic Evolution
02/18/04
Summary: Ever imagine making a telescope that was fifty light-years long, and could see into the mouth of the most dense objects known, a black-hole. Astrobiology Magazine talks to astronomer Hayley Bignall about what it takes to see into the center of an active galaxy.

How to Wind a Martian Watch
Topic: Mars
02/09/04
Summary: Time keeping on two sides of another planet turns out to be a challenge, at least when calibrated from our own rhythms. On Earth, it took thousands of years for navigators to get terrestrial time on some reliable global standards. But when not on our globe, the familiar clock ticks need a sun calibration.

Could Opportunity Find Life on Mars?
Topic: Mars
02/04/04
Summary: Andrew Knoll is a member of the Mars Exploration Rover science team and Fisher Professor of Natural History at Harvard University. His research focuses on ancient rocks on Earth; he studies how well they preserve evidence of ancient terrestrial life.
