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 heat.

EVAs are physically demanding, and sampling in full simulation suit makes it even more challenging and painstaking. The crew carries approximately 16-17 kg on their bodies when they egress the habitat (including the weight of oxygenator, helmet, boots, sampling tools and any extra baggage and gadget). With this weight, they reach difficult locations, they walk, as well as ride ATV and rovers on bumpy terrains, they climb the high cliffs and slippery mounds, they collect samples, and they generate media to send back to Earth. Although EVAs are challenging, they provide the crew with the opportunity to actually demolish their wall of comfort and go out to perform their respective mission activities. Sometimes, the crew members get cross-trained on the field to be able to replace the experts when needed. EVAs are essential for the success of the mission although they demand your sweat, thirst, and sometimes bruised bodies.

[The above data was recorded on Sol 20. By Sol 80, we had performed almost 60 EVAs as Crew. Personally, I spent 90 hours performing 29 Extra Vehicular Activities in the first phase of the mission]

¿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…

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

Posted by Andrew Planet on April 25, 2020 at 11:10am 0 Comments

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/
