Today’s EVA is a kind of a party given in appreciation of the our officers of Crew191 (Miho, Fumiei) service from the commander (Yusuke). Because Miho and Fumiei have withstood heavy pressure during this mission. Their expressions showed that this EVA will be a pleasant memory for the officers and of course for the commander. Yusuke was beside oneself with taking a officers’ picture with his camera. Their expression was so beautiful. After the EVA, we performed an closing ceremony of our SIM. Please read the operations above, then you could imagine our tricks!! We are all safely back to the Earth.

Narrative:
EVA today was a Recording Signal from the DIY Analog Signal Receiver with another version of antenna for the 3rd time.
We explored to URC North Site area and found a good 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.

Narrative:
After the EVA#9 team had leaved the HAB, Yusuke and Makoto started an operational EVA with a brush, towels, cleaner, and water for washing. We had already put the contaminated white tank inside the RAM on SOL9. As you know “RAM” is an abbreviation of the “Repair and Assembly Module”, but it never used as a purpose. So, today is the Memorial Day of RAM! Yusuke and Makoto got down into the tank only with underwear and cleaned it. Sometime they need to put their head out of a narrow mouth of the tank for breathing as a seal. We couldn’t complete cleaning the tank during this EVA, but almost done. The operation never realized without RAM. Thanks RAM!!!

EVA #10 – 2 Apr 2018 – Sol9
Crew members: Yusuke Murakami (EVA leader), Fumiei Morisawa, Makoto Kawamura

Objectives:
– Operational check
– Sample the water of the white tank and the black tank
– Empty the water of the white tank and move to the RAM

Operations:
10:37 – Entering the airlock
10:40 – Operational EVA start
11:17 – Entering into RAM’s Airlock
11:20 – Entering RAM
11:21 – Open the shutter of RAM
11:29 – Put the white tank inside RAM
11:36 – Entering the airlock of the HAB
11:39 – Entering the HAB

Narrative:
This morning we decided to cancel EVA#9 (Venzha’s CEMs Project) because we had the water tank problems. After the daily operational check, we checked and sampled the water inside the white tank and the black tank. Shannon had already pumped out almost all of the water this morning, we fully emptied the water from the white tank. After that we measured the size of the tank and also the shutter of the RAM. It seemed that the tank could be pass into the RAM through the shutter. So we tried it, and did it. So now we got a choice to clean the tank without breaking the SIM later on.
