Life is strange.

Innumerable forms of life exist on Earth in environments seemingly deadly to life as we once thought we knew it, where the existence of life was previously thought to be impossible.
Sunlight was once thought to be the ultimate source of energy for all terrestrial life. Exploration of Earth’s oceans provided surprising proof that life was capable of exploiting other sources of energy, and existing in environments formerly presumed to be utterly inhospitable to life. Tubeworms and several species of shrimp are but a portion of life discovered thriving at deep undersea volcanic sites in a chemical stew of seawater and poisonous chemicals, at near boiling temperatures. A diverse food chain has been discovered, beginning with bacteria thriving on the chemical and thermal energy of volcanic action, independent of solar support.
Closer to home in a more benign environment we have the changelings; tadpoles seemingly evolving themselves into frogs, and even more dramatic- metamorphosis: eggs becoming larvae, or caterpillars- in turn changing into pupae, or chrysalis- which finally change into moths or butterflies. It’s a truly amazing process.
Fungi, while considered a simple primitive life form, lead an incredibly complex life cycle- seemingly alien.
Perhaps the strangest fungi are the slime moulds, likely thriving in your own neighborhood. They live as individual amoebae-like organisms in compost piles or other rotting stuff, happy as a bacterium, until things go sour. When food gets scarce, hundreds of thousands of these odd microscopic creatures coalesce to form a slug-like “animal”, which migrates to a more hospitable location- and grows into a plant-like fungus, which releases spores to replicate in newly found piles of rot, repeating the cycle.
Bryophytes, a type of plant, are found in harsh environments from desert to polar. Some have been known to survive droughts of twenty years.
Wood frogs freeze during the winter and thaw during the spring, none the worse for it. Their blood sugar forms a kind of natural antifreeze, which protects their brains and other vital organs. The rest of the frog freezes solid!
The shield shrimp thrives briefly in temporary puddles formed by drenching rains. After eggs are hatched, the ponds evaporate and the adults die. The eggs lie dormant and dry until the rains come again, even years later. The desert shrimp lives a similarly interesting life- seemingly reversing its own extinction once water is again available.
Yaminals likewise appear to defy Man’s attempt to classify- animal, vegetable, mineral, or… none of the above? The seemingly impossible has proven to be probable and persistent.
It’s life, Jim- but not as we know it.
Sgt. Amy L. Meyer MD PhD was a sergeant in the Aerospace Guard Reserve. Sgt. Meyer was a devout Christian as well as a highly trained exobiologist with an acute scientific mind. Two weekends per month plus two weeks per year of service had largely financed her higher education. Apparently the Aerospace Force had presciently perceived an urgent need for top-grade exobiologists.
Even at the height of the Third Gulf War, Amy had not been called to active duty- until she was quietly activated for this “maintenance” mission, with orders to reveal to no one her true destination, and with no instruction as to the nature of her mission.
It’s difficult to train as an exobiologist- no exobiology had been discovered- until now- and said discovery was classified. Much of the training consisted of developing an encyclopedic mastering of the life sciences combined with intense study of the more unusual varieties of earth life, those subject to unusually harsh conditions similar to those that might be found elsewhere in our solar system, and eventually beyond. Dr. Meyer had dealt with the ridicule and skepticism inherent in a specialty with no proven reason to exist, as well as the vestigial sexism still extant yet in our so-called “enlightened age”.
And, having just arrived on Mars, left clueless to her mission until some beet-like freak emerged from the ground and bit her hand, now that life on Mars had quite evidently been discovered, she was to be sent packing!
Dr. Meyer did not plan to go quietly.
