\begin{abstract}
Searching for life on other planets and planetary bodies poses a number
of challenges, especially given that there is currently no clear
evidence that lifeforms can only conform to characteristics observed on
Earth. While current astrobiology missions operate under the assumption
that any astrobiological entities of interest will have similar
properties to organisms on Earth (`canonical' lifeforms), the current
convention of searching for direct evidence of such lifeforms (e.g.
organic compounds, genetic material, etc.) is largely exclusionary to
any biologically valid lifeforms which are not currently a part of the
canonical model of life that is used to drive exploratory efforts. It is
proposed that the definition of life be broadened to include any
entities capable of maintaining homeostasis relative to an entropic
environment. Thus, instead of the traditional strategy of searching for
direct evidence of life conforming to Earth-based standards, i.e.,
looking for specific organic compounds, a new strategy could be used to
indirectly identify lifeforms through their utilization of environmental
resources (e.g. as energy sources).%
