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 0 Likes
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…

¿Are the Venusian sulphuric acid clouds the by product of long dead anoxogenic photosynthetic organisms?
Posted by Andrew Planet on May 4, 2020 at 2:51pm 2 Comments 0 Likes
I just read the piece at the link below entitled "Study: Life might survive, and thrive, in a hydrogen world."
I'd been thinking on similar lines recently, on different atmospheres with early life, but I was considering anoxogenic bacteria whose byproduct is sulfur instead of molecular oxygen. ¿Had life evolved on Venus could its sulfuric clouds be the signature byproduct of such life with no branches ever evolving to produce the equivalent of Earth's Great…
