On September 29, NASA described its astrobiology program to a Congressional House Committee, emphasizing its need for a joint effort from varied academic disciplines and the development of new technology and instrumentation.
Difficult problems include how to detect life forms unlike those on Earth and how to present cross contamination between Earth and other moons and planets. Astrobiology could also help us understand how life evolved on Earth, as it strives to detect actual life forms in seemingly habitable environments.
Studies listed include a search for habitable environments within and beyond our solar system, evidence of prebiotic chemistry and life, and life’s potential for adapting to environmental challenges.
Hundreds of astrobiologists worked together to define “goals and
objectives” for astrobiology research. Current work was described in “Astrobiology Strategy,” a 250 page document with editor-in-chief JPL’s Lindsay Hays.
Six major topics discussed were
1) identifying the non-biological source of organic compounds,
2) the role of macromolecules in the origin of life and how they are synthesized,
3) how complexity increases in early life,
4) how life and environment change together and co-evolve,
5) finding and exploring habitable environments and signs of life, and
6) building habitable worlds.
Key research questions conclude the report and offer challenges and opportunities, including the need to “…break traditional boundaries between the physical sciences and other areas of human inquiry…” What is not included is the philosophical impact that finding other worlds and exolife might have on human beings, a topic Caleb Scharf covers thoroughly in his book The Copernicus Complex: Our Cosmic Significance in a Universe of Planets and Probabilities—a readable overview of astronomy and all the related sciences it draws on. I’ll be reviewing the book on Goodreads soon.

Cary's first novel and Webs of Varok prequel A Place Beyond Man was originally published in 1975 by Charles Scribner’s Sons, Dell, and Millington, London. Cary re-released A Place Beyond Man as an Author’s Guild Backinprint edition, now available from online booksellers. Its themes of sustainability and interspecies cooperation have now grown into new adventures for its human, elll and varok family as they travel the alternate 21st century Solar System in the five-volume Archives of Varok, coming from Penscript Publishing House in 2012–2014. Cary’s other works include two musical science fiction comedies “U.F.F.D.A.!” and “Petra and the Jay,” as well as newspaper and magazine articles, essays, short stories, and book reviews for The Christian Science Monitor.
