Woman in Black
Cassie Conley. Image Credit: Paul Alers, NASA.No, she doesn’t wear a dark suit and darker glasses, and yes, she still has her fingerprints. But that doesn’t change the fact that Cassie Conley, NASA’s planetary protection officer, is in charge of protecting Earth from alien invasions.
Science Careers is currently featuring a profile Dr. Conley on their website…check it out to learn more about planetary protection, and the evolution of a fascinating career.

Calling the Planetary Police
Today’s astrobiologists face a difficult task when building a contamination-free spacecraft. By the rules of planetary protection, the more likely a location is to harbor life, the more difficult it is to visit. Researchers are now working on new ways of sterilizing spacecraft built on Earth in the hopes that soon no place in the solar system will be off limits for exploration. A special feature concerning their work was recently published in the journal Nature.Source: [Nature]

Alien Safari Part 5: Alien vs. Predator
At the most recent NASA Astrobiology Science Conference, a panel of scientists discussed different types of planets where we might find alien life. In the fifth segment of this series, the panelists address questions from the audience about the search for life on Mars and elsewhere.

Surviving STS-107
Rocco Mancinelli, PI of NAI’s SETI Institute Lead Team, and member of NAI’s NASA Ames Research Center Lead Team joined researchers from KSC and Ames, as well as NAI’s Former Director, Barry Blumberg, in studying populations of C. Elegans which survived the atmospheric breakup of STS-107 during it’s fatal re-entry. Their results are published in Astrobiology. Five canisters were recovered, and live animals were observed in four of them. This demonstrates not only the ability of the culture medium to support the organisms during spaceflight, but also the ability of the animals to...
