"Do we grow our own food on the International Space Station? If not, what plants are good candidates?"
Content with the tag: “signatures of life”
Determine how to recognize signatures of life on other worlds and on early Earth. Identify biosignatures that can reveal and characterize past or present life in ancient samples from Earth, extraterrestrial samples measured in situ, samples returned to Earth, remotely measured planetary atmospheres, surfaces and technologies.

Coping with Contamination
Carol Stoker is the principal investigator for the Mars Analog Research and Technology Experiment (MARTE). MARTE has just begun its second field season drilling into the subsurface near the headwaters of the Río Tinto in Spain, searching for novel forms of microbial life. In a four-part interview with Astrobiology Magazine Managing Editor Henry Bortman, conducted just before Stoker left for Spain, she explained what MARTE hopes to accomplish. In this third part, Stoker described how...

Extracellular Protein-Metal Aggregates: A New Biosignature?
Deep inside a flooded mine in Wisconsin, scientists from NAI’s University of California, Berkeley Team have discovered an environment in which bacteria emit proteins that sweep up metal nanoparticles into immobile clumps. Their finding may lead to innovative ways to remediate subsurface metal toxins, and have exciting implications for identifying biosignatures on Earth and other worlds. The research, published in the June 14th issue of Science, was done in collaboration with a team from the U.S. Department of Energy’s Lawrence...

Astrobiologists Discuss Mars Habitability on NPR
Last week, NAI scientists were featured in a live broadcast of NPR’s Science Friday. Tune in to hear how astrobiologists are following the water and the energy, trying to target those parts of the planet most likely to harbor life. Plus, learn how the rovers Spirit and Opportunity have changed our ideas about the Martian environment, and what evidence future missions will look for.
