Astroecology is the scientific study of the interactions of life with space environments and resources. The results quantify the immense potentials for future life in the Solar System and in the galaxy.
Cosmoecology extends these studies to potential life and its resources throughout the universe, for trillions of eons when viable matter will exist, or indefinitely.
The principles of astroecology, experiments on biological resources in space, the cosmological potentials for life, and securing that future, are summarized in the e-book
"Seeding the Universe with Life: Securing Our Cosmological Future" (free download)
Can space resources support life?
Recent experiments showed that microbes and plant cultures (asparagus, potato) can grow well on carbonaceous and Martian meteorites. This suggests that asteroid and Martial soils are fertile.

How much life can the Solar System support?
Analysis of nutrients in meteorites show that carbonaceous asteriods can support a hundred million trillion kilograms of biomass and human space populations of thousands of trillions.
How can we measure the amounts of life?
The total amount of life in a ecosystem depends on the amounts of biomass and its duration, expressed as time-integrated biomass (kg-years). For example, the amount of life on Earth to date is about quadrillion kg x billion years = 1e24 kg-years. Potential future life in the Solar System, based on asteroid and cometary materials, is much greater, 1e28 - 1e34 kg-years.
What is the future of life in the galaxy?
Life can survive about white dward stars for trillions of years, supporting astronomical amountsof time-integrated biomass.
How much life can the universe sustain?
If all mass were converted to living matter, and then used up slowly for energy to support life, the universe could contain an immense 1e57 kg-years of time-integrated biomass for trillions of eon.
What is our cosmological future?
For now, we must secure long-term human survival. For our descendants life an continue for millions of eons. Out descendants may then understand nature more deeply and seek to extend life indefinitely. In that future, our human existence will find a cosmic purpose.
