Event Description

Join us on Monday May 18th at 10 am US Pacific time (GMT-8) for a LIVE event with Astrobiologist and Planetary Scientist Dr. Jennifer Heldmann of NASA!

Heldmann’s scientific research interests focus on studies of the Moon and Mars. Her Mars research focuses on studies of recent water on the Red Planet through spacecraft data analysis, numerical modeling, and fieldwork in Mars-analog environments such as the Outback of Australia, the Canadian High Arctic, the Atacama Desert, Spitsbergen, the Mojave Desert, and Antarctica, among other locales. Her work focuses on martian and terrestrial gully features which can be indicative of geologically recent liquid water activity. Liquid water is especially important to understand climate, geology, and the potential for past and/or present life on Mars. She also studies surface and subsurface ice deposits on both Earth and Mars to further understand the physics, geomorphology, and potential habitability of such cold icy locales in the Solar System.

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

¿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

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…
