Marco Polo and Meteorites
Asteroids and comets have been a major focus of recent NASA missions. From Deep Impact to Stardust, and the current Dawn mission, astrobiologists have been examining these fascinating celestial bodies in order to understand the role they may have played in the origin of life on our planet. These rocks in space are also ancient records from a time when our solar system was being born. The wealth of scientific information that can be gleaned from asteroids has also sparked interest from space agencies outside of the United States....Source: [Astrobiology Magazine]

Astrobiology and Stardust
Carl Sagan once said “We are all star stuff.” But how? What does that really mean? One of the fundamental questions of astrobiology, how does life originate and evolve?, provides a structure in which to examine the relationship between life and the cosmos. Everywhere life has been found on Earth, which is essentially every place in which it has been sought, life’s intimate connection with water has also been found. Within the framework of contemplating life’s cosmic origins, one must also ask about the history of water on Earth. NASA’s Stardust mission has provided the opportunity for astrobiologists to gain deeper insight into this history.

Chance to View Stardust Return
NASA’s Stardust mission is nearing Earth after a four billion kilometer round-trip journey to bring back comet dust samples. Viewers in California, Oregon, and Nevada have a chance to see the fiery entry of the return capsule into Earth’s atmosphere in the early morning of Sunday January 15 (approximately 2 a.m. PST, 3 a.m. MST).
