dc.description.abstract Panspermia, or the idea that sources of life are distributed throughout the Universe via transportational units such as meteoroids, has become a tantalizing possibility throughout the realm of astrobiology. In this experiment, Artemia franciscana (brine shrimp a.k.a. Sea Monkey) embryos under different encystment states (dehydrated, hydrated-capsulated, and hydrated-decapsulated) were exposed to extreme vacuum and ultraviolet radiation conditions similar to those found in space in order to determine whether or not they could be a prototypical organism for this theory. Quantitative analyses were done by calculating Artemia hatch rates for umbrella, naupliar, and both umbrella & naupliar stages following treatments. Although hatch rates varied, exposure to these extreme space-like conditions did not completely impede the viability of the encysted Artemia studied. This suggests that encysted Artemia franciscana may be a model organism supporting the theory of panspermia, although the effects of encystment state during exposure to other space-like conditions besides extreme vacuum and UV radiation warrants further investigation. en_US
