Astroecology concerns the relations between life and space resources, and cosmo-ecology extrapolates these relations to cosmological scales. Experimental astroecology can quantify the amounts of life that can be derived from space resources. For this purpose, soluble carbon and electrolyte nutrients were measured in asteroid/meteorite materials. Microorganisms and plant cultures were observed to grow on these materials, whose fertilities are similar to productive agricultural soils. Based on measured nutrient contents, the 10 22 kg carbonaceous asteroids can yield 10 18 kg biomass with N and P as limiting nutrients (compared with the estimated 10 15 kg biomass on Earth). These data quantify the amounts of life that can be derived from asteroids in terms of time-integrated biomass [BIOTA int = biomass (kg) × lifetime (years)], as 10 27 kg-years during the next billion years of the Solar System (a thousand times the 10 24 kg-years to date). The 10 26 kg cometary materials can yield biota 10 000 times still larger. In the galaxy, potential future life can be estimated based on stellar luminosities. For example, the Sun will develop into a white dwarf star whose 10 15 W luminosity can sustain a BIOTA int of 10 34 kg-years over 10 20 years. The 10 12 main sequence and white and red dwarf stars can sustain 10 46 kg-years of BIOTA int in the galaxy and 10 57 kg-years in the universe. Life has great potentials in space, but the probability of present extraterrestrial life may be incomputable because of biological and ecological complexities. However, we can establish and expand life in space with present technology, by seeding new young solar systems. Microbial representatives of our life-form can be launched by solar sails to new planetary systems, including extremophiles suited to diverse new environments, autotrophs and heterotrophs to continually form and recycle biomolecules, and simple multicellulars to jump-start higher evolution. These programs can be motivated by life-centered biotic ethics that seek to secure and propagate life. In space, life can develop immense populations and diverse new branches. Some may develop into intelligent species that can expand life further in the galaxy, giving our human endeavors a cosmic purpose.

“…Microbial interactions with planetary regolith could also be used to control and prevent regolith moving downslope (mass movement) in enclosed settings (Liu et al 2008) or be used as the precursor to soil formation (Mautner 2002;Kral et al 2004;Lytvynenko et al 2006).…”

In this paper, we describe the development of an International Space Station experiment, BioRock. The purpose of this experiment is to investigate biofilm formation and microbe-mineral interactions in space. The latter research has application in areas as diverse as regolith amelioration and extraterrestrial mining. We describe the design of a prototype biomining reactor for use in space experimentation and investigations on in situ Resource Use and we describe the results of pre-flight tests.
