ASTEP (Astrobiology Science and Technology for Exploring Planets)
ASTEP (Astrobiology Science and Technology for Exploring Planets) combines the science and technology communities in order to enable future space missions to determine whether life exists or has existed outside Earth. Through a detailed, collaborative analysis of Earth's extreme environments, we can better prepare to understand analogous systems elsewhere. The focus of upcoming ASTEP projects, for which we are currently soliciting proposals, is to validate and improve existing technology, preparing it for future flight missions to test for life in our solar system and beyond.

Biogeosciences at NSF
Geomicrobial processes (the dynamic interaction of microbes with earth materials) lie at the heart of the Biogeoscience program solicitation for FY 2004. The Directorate for Geosciences invites the scientific community to submit proposals to conduct innovative research into fundamental geomicrobial processes, which constitute the foundation of the biogeosciences. Microbial communities exist within a broad spectrum of environmental conditions including those found at the Earth's surface, deep in the crust, in freshwater environments, within the oceans and possibly the atmosphere. These communities are involved in a broad array of geological and biological processes involving the evolution of the Earth, ecology, geochemical cycling, biomineralization, mineral ore formation, lithification and energy production. Geoscientists and bioscientists alike have discovered that microorganisms influence the Earth's environment through an astonishing array of chemical processes. Indeed, at lower temperatures and with geological time thermodynamic processes may be less important than kinetic processes mediated by microbes. The presence of certain trace gases in the atmosphere, the acidification of mine-waste waters, and metal distributions in soils and sediments are all products of these micro-scale chemical reactors. Microbes form the foundation for all ecosystems known, both terrestrial and marine. Despite their importance and omnipresence, more than 99% of microbes on Earth remain uncharacterized, many from unique or incompletely explored environments.
Proposals are due by April 1, 2004 5pm local time.

NSF Research Coordination Networks in Biological Sciences
The goal of this program is to encourage and foster interactions among scientists to create new research directions or advance a field. Innovative ideas for implementing novel networking strategies are especially encouraged. Groups of investigators will be supported to communicate and coordinate their research, training and educational activities across disciplinary, organizational, institutional, and geographical boundaries. The proposed networking activities should have a theme as a focus of its collaboration. The focus could be on a broad research question, a specific group of organisms, or particular technologies or approaches.
