Halftime on Mars, And still a lot off to do. This was the coldest night in Mars Desert. Our outer thermometer has shown minus 15.2 centigrade. As a result our fresh water tank outside the Habitat was frozen, also the pipe for the wash inside of the bathroom. So the crew could not have a wash in the morning. So it was not possible to refill the tank right now. Greenhab: same procedure as every day. The grey water recycling system does not work.

We worked on the problem and found out, that the flexible tube was disconnected between a pump and the UV filter, so there was no water flow and the pump was running hot. Probably we can use it tomorrow again when it is cooled down. Otherwise we will need a new pump.

In a real Mars Mission, absolutely no samples must be brought into the Habitat because of contamination of the Habitat. So it is necessary to analyze all the samples outside the Habitat. Based on this fact, we have positioning a geological work station outside the Habitat. All the samples we have collected on our last EVA`s has been stored outside in a box. So our geologist Sigrid was able to make a first basically survey. This was done as an EVA, in the same way as it must be done on Mars.

On a scouting EVA, up to the north western direction, Heike and Klaus found the debris of our pillow. Just approximate 5 kilometers away from the Habitat. We have seen that the pillow was broken just at a joint of the skin. We took it back to Habitat and documented it.

At 3:32 p.m. Patrick and Tom started to make another one scouting EVA for geological overview. They found a fantastical landscape also in north western direction from the Habitat. At 5:16 p.m. they returned to MDRS with a lot of data and beautiful pictures.

Like yesterday, the TV team accompanied the first and the third EVA. While Patrick and Tom were on EVA the rest of the crew cleaned the Habitat. Here one thing I must say. Seen from my point of view it is necessary to have the Medias with us for good public relations of Mars exploration. But, when the Medias will be with you most of your mission time, you can be sure, that nearly 50 % of all the planned experiments or tests will be not able to do on your mission.

After unsuiting the EVA team, the crew started with an analysis of the day. Once more the TV team has shot the meeting and the entire atmosphere inside of the Habitat.

Now we are in time to write our reports.
