Today we had a day off! So nothing to describe, instead of that, we introduce our non-human crew: two robot-dog “Aibo”s and the automatic hydroponic machine “foop”.
Aibo, the lovely dogs ease the tense atmosphere in our closed life.
The machine foop is made for interior and we can see the process of plant’s growth.
They do NOT attend briefing, clean up the HAB and of course no EVA, but they are definitely part of our team and big support for us.
MARS atmosphere is about more than 100 times thinner than Earth’s. And without a “thermal layer”, MARS can not retain any heat energy. On average, the temperature on MARS is about minus 80 degree Fahrenheit (equal : minus 60 degrees Celsius). And the next question is, why we “able” to feel cold?
Two thing that make me interested to find the answer of this question, first we feel cold because of Iron Level in our body, means that Iron is a critical part of the blood. It helps red blood cells to carry oxygen around the body, ensuring each cell can function properly. Equally, iron deficiency can impact this process, and it is believed that this can lead to feeling cold all the time. A scientific study aimed to identify the relationship between iron levels and body temperature. Other reason is Heat Transfer. , and remember that there are three ways that heat can transfer: conduction, convection and radiation.
And…
How we can know that we have a feeling about things HOT or COLD then?
“Hot” and “cold” are relative terms that we can use to compare how things feel when they have more or less of a certain kind of energy we call heat.
Our Commander, Yusuke Murakami : took the first shower in the 2nd day of the mission, with “out of service heater” 🙂 Cold as hell he said,
Like a… “Mars ain’t no kind of place to raise your kids; in fact it’s cold as hell” sang the legend Elton John : “Rocket Man”!, and although the song was released in 1972 — four years before our robotic machine from earth was the first successful landing on MARS Planet. Once Again, MARS was our long period of the imagination on science fiction history before crazy scientist create a rocket. And MARS Isn’t as Earthlike as it might look.
MDRS is on Desert,
And Fact that ; In that way MARS is like an Earthly desert; even after a blisteringly hot day the temperatures can plummet at night, leaving an ill-prepared camper shivering beneath the cold glow of starlight. Except on MARS, where the Sun is only 50% as bright as on Earth and the atmosphere only 1% as dense, the nighttime lows dip to Arctic depths. Our experience here on MDRS took us into one journey of other side of imagination about MARS look like, and perhaps one project from Wataru Okamoto ; DIY machine called PM2.5 – a measurement instrument as for : Environmental Monitoring System will make complete. And in this mission, he can tell us about Calculation of Mass Concentration in the air and develop from Stand Alone instrument into wider range type of measurement tools that we can explore more to be aware about our environment.
“Deserts on Earth have very extreme temperature ranges,” says Mars Science Laboratory Deputy Project Scientist, Ashwin Vasavada. “So if you take a desert on Earth and put it in a very thin atmosphere 50% farther from the Sun, you’d have something like what we’re seeing at Gale Crater.”
Then we are here ! 🙂
So, how cold is space? That’s a nonsense question. It’s only when you put a thing in space, like a Space Ship, rock, MDRS space suit, or an astronaut, that you can measure temperature.
To the next our curiosity ; Are we ready for the COLD WORLD up there? MDRS is one of the option to test and to learn how to stay and focus on the rules and practicing MARS space protocol. Lots of impression and keep us warmer with those chaotic and activities. Like we sucked up into an alternate Time Tunnel 🙂

General notes and comments: Solar system seems unusual from yesterday. We had precise monitoring and also discussion about this problem with Dr. Shannon this morning. The findings of the monitoring are that solar charger system looks fine, but the number of monitor telling us wrong result for some a while. For example, 11:11 SOC has changes from 63% to 100% suddenly. We will keep monitoring. Attached is the solar battery parameter.
Summary of internet: Under control
Summary of suits and radios: No problem
Summary of Hab operations: Shower heater doesn’t work.

It’s already passed 6 days since we’ve arrived here, so we decided to clean inside the HAB this morning. After all of the room got clean, we also felt refreshed.
Today’s EVA, Venzha Christ did the first recording on Mars but in “The Moon”. The recording has been successfully done, but the rover Opportunity has overheated several times on the way. So that’s why the EVA team could not return on time, but it might be a good “opportunity“ to learn to keep schedule.

Narrative:
EVA today was a Recording Signal from the DIY Analog Signal Receiver
We explored to White Moon area and found an amazing place for the project.
This project had a title : Space Weather Impacts On Climate,
: means that all weather on Earth, from the surface of the planet out into space, begins with the Sun. Space weather and terrestrial weather (the weather we feel at the surface) are influenced by the small changes the Sun undergoes during its solar cycle. Space Weather impacts numerous facets of everyday life, from where airplanes can safely fly, to how accurately a farmer plows his field. In addition, there are a large variety of phenomena that are driven by the variability of the sun over periods ranging from hours to years. The most important impact the Sun has on Earth is from the brightness or irradiance of the Sun itself. By build an antenna we can get specific signal that will received by this Analog Signal Receiver.
As a result, we will analyze all signal and frequencies we got from today and will have a visualization from those signal.
