Astrobiology (NASA) – http://astrobiology.nasa.gov
Representative questions that can be answered with this resource:
- What is the Galactic Habitable Zone?
- What can earth glaciers tell us about life in outer space?
- What are the lakes on Titan made of?
The website is divided into a number of sections. Sections that appear to be more useful for writers and the general public include:
About Astrobiology – A brief overview of what is meant by Astrobiology.
Astrobiology Roadmap – From the website,
The Roadmap addresses three basic questions: how does life begin and evolve, does life exist elsewhere in the universe, and what is the future of life on Earth and beyond? Seven Science Goals outline the following key domains of investigation: understanding the nature and distribution of habitable environments in the universe, exploring for habitable environments and life in our own Solar System, understanding the emergence of life, determining how early life on Earth interacted and evolved with its changing environment, understanding the evolutionary mechanisms and environmental limits of life, determining the principles that will shape life in the future, and recognizing signatures of life on other worlds and on early Earth.
The Roadmap was last updated in 2008 and is available as a 16 page PDF file. Previous roadmaps from 1998 and 2003 are also available.
Focus Groups – From the website, “Astrobiology Focus Groups are open to the entire astrobiology community. Each addresses a topical area of particular community interest. Focus Groups provide venues for developing research areas across the broad astrobiology community, stimulating new areas of research, promoting long-distance collaborations, and contributing to astrobiology space missions.”
Clicking on names of focus groups will bring up a description of the group and work products, if any. For example, Icy Satellites Environments Focus Group, which focuses on Titan and Europa along with other bodies suspected of having oceans of water or other liquids, provides a listing of activities, meeting minutes, and presentations. A glance at the presentations for this group found two Titan related items that might inform a science fiction story:
- Seasonal changes in Titan’s weather patterns bring extensive methane rainstorms to Titan’s low latitudes
- Titan’s Lakes and their Role in the Methane Cycle
The presentation on Titan’s lakes had a handwritten summary of the “Huygens landing pool” in addition to providing material and the location and composition of methane lakes on Titan.
Other current focus groups include Lunar, Mars, Habitability and Astronomical Biosignatures, and Astrobiology and Society. This last group put out a six page white paper in 2010 discussing ways that future discoveries in astrobiology might affect society.
Education and Outreach – A set of articles and multimedia aimed at students and the general public. At least one of the articles is focused on the use of story telling in science education. Other articles are about early earth or reflections on exoplanets.
Seminars and Workshops – Webcasts of lectures from the NASA Astrobiology Institute. Webcasts seem to last about an hour and are somewhat technical but can be followed along. Lectures during 2010/2011 included:
- Hydrothermal Conditions and the Origin of Cellular life
- ESA/NASA ExoMars/Trace Gas Orbiter: A Search for Extant Habitability and Habitancy
- Anaerobic Thermophilic Lithoautotrophs: Life Without Light and Oxygen
- Permafrost Astrobiology: Field Expedition to Terrestrial Analogues of Martian Habitats and Inhabitants
This section also links to webinar archives on astrobiology from other institutions.
Events – A listing of upcoming meetings and symposia. Some on exotic topics like Volvox (Volcano dwelling algae).
Directory – Directory of every astrobiology team member. Information varies. All staff records will have an e-mail address. Some may have listing of current projects and publications.
Article archives – Appears to be a reverse chronological, tagged listing of every item appearing on the website. Notable items that appeared in 2011 included:
- Timeline of a Mass Extinction
- Great Lake on Europa
- In Search of Virus Fossils
- Living in the Galactic Danger Zone
- Jupiter’s “Grand Tack” Reshaped the Solar System
Ask an Astrobiologist – An archive of Q&As related to astrobiology, astronomy and science in general. Answers can be searched or browsed by newly answered or popular. Questions will be answered in 2-3 weeks and you’ll get a link with the answer. Users are encouraged to search or browse for answers first. There are also many resources for debunking 2012 myths.
Some of these sections link to the component institutions of NASA Astrobiology – NASA Astrobiology Institute, Astrobiology Science & Technology for Exploring Planets, Astrobiology Science & Technology Instrument Development and Exobiology & Evolutionary Biology. This makes the navigation somewhat odd at times. Just click on the AB Home or “Astrobiology Home” to find your way back to the primary website.
