Sol 92 - The Crew 172 - Final words

SOL 92 [14 January 2017]

Crew 172 is precious for me and will always be. Personally, after living 80 sols with an amazing team, coming back to the hab with a different team was a little challenging. They said they had been following our Mars160 mission but we all were strangers for each other. But I think we all went through the process well because we all had a single goal – a successful mission.  We are the Mars Society Crew. I would say that I see an immense potential in…

Sol 86: An Unforgettable EVA!

Sol 86 [8 January 2017]

My Sol 86 - “HabCom, HabCom, This is EVA Team… Over” – An unforgettable EVA

It was Sol 86. Actually, for Crew 172, it was Sol 6, but I would call it Sol 86 because for me this mission is an important continuation of Mars160 science operations.

So, we all woke up at 7 am and got ready for the breakfast by 7:30 am. This was going to be a busy Sol for me because at 8:30 am, I was supposed to meet with an Earth-based…

Sol 92: When you are on Mars… a short note after my 92-sol mission

SOL 92 [14 January 2017]

You are on Mars.

When you are on Mars, life is unpredictable (just like on Earth, but on Mars, it’s a little bit more). I have always written about the beauty of this place; how those small portholes of our Martian cylindrical home let us gaze the surreal red backdrop and make us immerse into our own sense of awe and appreciation. How our home stands tall against all the oddities of Mars. Living in this place, sometimes you feel that you…

Sol 80: Mars160 Phase One - Final words

Sol 80 [13 December 2016]

Mars 160 mission in the Utah Desert is towards its end. I think we have not just performed a Mars simulation, but lived a life; a life which was entirely different from what we had been living. It is a bonding that we have created with our hab and with each other. We became a family. We had our both funny and stressful moments like all families have, but I think somewhere, we all learned to be unconditional in our…

Sol 81: I am on Mars, again!

SOL 81 [3 January 2017]

I am on Mars, again! It feels wonderful saying that.

I recently completed the first phase of Mars160 mission. Now, I have joined the Crew 172. For this mission, I am the Executive Officer and Crew Biologist for another 15 sols.

It is my Sol 81. Before coming here as Crew 172, I was asked many times that why do I want to do this rotation when I had already been part of a long-term mission like Mars160. My answer has always…

Sol 75: EVA Narrative: Canyon, Silence and Us

Sol 75 [8 December 2016]



Yesterday morning, Jon, Annalea, Anastasiya and I headed for another adventurous EVA. This EVA was supposed to be in semi-simulation because the sampling site was 75 km away from our habitat and generally accessible to the public. We started gearing up at 10 am. The EVA team entered into the airlock at 10:30 am and started depressurization. Since we were supposed to travel ~75 km, we took PEV (Pressurised Exploration Vehicle) to get to the location. This…

SOL 64: Gypsum Astrobiology

Sol 64 [27 November 2016]

On Earth, gypsum (CaSO4.2H2O) is deposited via evaporation of calcium and sulfate-rich water. Gypsum is fragile, mostly translucent and occurs as thick, sedimentary evaporite beds. It is fairly common mineral on Earth and can be found around the salt lakes, hot springs, and veins of sulfate solution. Since it is relatively easily dissolved in the water gypsum is rarely found at the surface except in deserts. In hydrothermal systems, gypsum can…

Sol 60 - How it all started and lessons learned

SOL 60 [23 November 2016]

What am I doing?! I think I’m trying to record hypolith abundance (Image Credit: Crew Geologist Dr Jon Clarke – and The Mars Society) 

My journey of MDRS started off as a volunteer. In 2014, I joined the MDRS Mission Support as a CapCom and that’s how I first became part of this ambitious idea of human…

SOL 52 - EVA Narrative: Challenges and Accomplishments

Sol 52 [15 November 2016]



Another intense EVA!



Today, Annalea, Anastasiya and I headed towards the field site at 9:17 in the morning. After gearing up, we went inside the EVA airlock, simulated depressurisation and egressed the hab. Our first task was to remove the two trash bags from the hab. This EVA was basically focused on collecting hypolith abundance data and taking the sample back for macroscopic measurements of hypolith colonies.

The first lesson learned…

SOL 60: Constraints of Science Operations on Mars: Lessons Extracted while Performing Mars Simulation

Sol 60 [23 November 2016]



We are performing Mars simulation in the Utah Desert and doing rigorous science on field during EVAs. However, sometimes your approaches are constrained in the heavy spacesuit and in absence of highly specialized equipment. That’s what I learned while conducting science operations in this simulation. A proper sample collection regime in sterilized conditions is the first and the most significant step before those samples are processed in the laboratory.…

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…

¿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/
