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

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

¿Are the Venusian sulphuric acid clouds the by product of long dead anoxogenic photosynthetic organisms?

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…

100 years tomorrow 26th April 2020 since we looked beyond the Milky Way Galaxy

Exactly 100 years ago tomorrow, the subject on whether this Universe is larger than the Milky Way Galaxy was brought up publicly at an event sponsored by the National Academy of Sciences, known as The Great Debate. Until then the Milky Way was thought to be this Universe.  Conference at the NAS http://www.nasonline.org/about-nas/events/annual-meeting/nas157/

Panspermia, the which came first, the chicken or the egg question?

Below is a comment I wrote on

http://www.skymania.com/wp/2011/03/life-from-space-expert-loses-funding.html/3686/

The problem with panspermia is that if life on Earth came from some other location in outer space, where did it come before that and so on with no end. Water, the universally…

Always make a back up of what you write

Have you ever had an untested idea, which could be right or wrong, written meticulously about it on a webpage article and then have that page replaced by another purportedly back dated?  It happened to me quite curiously.  I'm sure of it because the posting service the webpage provided allowed for the user to re-edit the comment which I did several times revisiting the page.  Then one day, after a couple of weeks I visited the webpage again to see whether anyone had commented on my post and…

Self fixing space suits

Space suits ought to have a liquid within for self sealing punctures from inside them just like the sealant I use in the wheel air chambers for my own motorbike's wheels.  I have not had a puncture in years. The sealant I use can handle pencil width holes.  I mean the sealant that you place inside a deflated new wheel chamber before inflating it, not the sealant used after a puncture. …
