Sol 20: Hours spent performing Extra Vehicular Activities so far!

Sol 20 [14 October 2016]

It is Sol 20, and after many strenuous extra-vehicular activities performed by the MARS 160 crew at MDRS, it is worth documenting and acknowledging how many hours the crew spent performing rigorous science and engineering activities. Our Executive Officer Yusuke Murakami did this exemplary job by generating this data for individual crew members. So, in totality, the entire crew spent 152 hours outside the “Martian” vehicle under the scorching…

Diaries of Mars 160 Twin Desert-Arctic Analog Mission Phase One and Crew 172 in Utah Desert

Hi, SAGANauts!

Here I am with some selected pieces from my diaries written over a period of three months as part of MARS 160 Twin Desert-Arctic Analog Mission and Crew 172. Mars 160 mission recently culminated its first phase at Mars Desert Research Station (MDRS) in the Utah Desert. The second and final phase of this Mars simulation mission will take place at Flashline Mars Arctic Research Station (FMARS) in the High Arctic this summer. Both FMARS and MDRS, founded and…

C. Elegans (nematodes) in Space?

I am a university student who might have an opportunity to join a team sending a small rocket into space and it contains a couple experiments, one of which will be a culture of C. elegans. I know a bit about c. elegans and that they are sent to space as models of simple life, but I was wondering if someone could point me towards more profound space research on them.

Does anyone know about the experiments involving Caenorhabditis Elegans in space and what research could be done…

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…
