Europa, Enceladus, and Titan

Posted on March 22, 2018 at 6:49pm 0 Comments

Based on recent readings, especially from Christopher McKay in How to Search for Life on Other Worlds, I’ve come to believe that life only needs the right combination of three main requirements: a main solvent to host chemical reactions (ours on Earth being water), a mixture of common building-block elements (Carbon, Hydrogen, Oxygen, Phosphorus, Nitrogen, Sulfur are examples of this), and enough energy to cause chemical reactions.  In Astrobiology lecture, we have discussed life…

The Most Adaptable Species

Posted on February 3, 2018 at 1:12pm 0 Comments

When we think of the most adaptable species, what comes to mind? Camels are able to survive without food or water for months, cockroaches are said to have survived the atomic bombs on Hiroshima and Nagasaki in World War II, and Emperor Penguins are able to make journeys 60+ miles long with their last meal being four months earlier. All of these species are very well suited towards their particular environment, but if one were to put a camel in Antarctica, or an emperor penguin in the Gobi…

Why Limit Our Definitions?

Posted on January 18, 2018 at 5:59pm 0 Comments

Astrobiologists, amongst other biological scientists, have not yet settled on a standard definition for what they consider to be life; this is because there are so many loopholes and exceptions to each new definition-theory that we come up with. To a FAR lesser degree it is almost like trying to come up with a standard definition of a hamburger. Is it two separate bread buns with a beef patty in the center? What about protein style at In-N-Out where the buns are replaced by a lettuce wrap?…

Using tried and tested methods of constructing habitats from ethnobotanical and ethnozoological useful species for self sustainability on Mars

Posted by Andrew Planet on June 26, 2020 at 8:00am 0 Comments

To maximize crop yields on Mars it would be advantageous to do away with annuals and biannuals by engineering the latter into perennials as standard. Not only would that entail far less work to grow produce as the act of replanting is made obsolete, but per given cultivated area perennials bring forth more food and materials with less demand from the soil than the equivalent of annuals.

Imagine a superfood annual such as lentils engineered into a lentil tree for which there already…

Radiolysis-powered life

This paper greatly extends the possibility of what a Goldilocks zone can be.  Its no longer the Goldilocks zone as a single expanse, its the Goldilocks zones for a particular area
