Commander's Check-In Report

Anne-Sophie Kalbfleisch Reporting

Crew Physical Status: Everybody's fine Time Departed/Returned from EVA:


Brief Narrative of Field Mission Results:

The aim of the EVA was to install the antenna outside as a part of the


We spent almost the whole day with our experiments with the algae. We

made some measurements in order to determine the optical density of

our algae solution. Each measurement was made 5 time in order to get a

good average and this took a lot of time. After that, we assembled

the tubes and pipes but until now we have had some problems because

the junctions weren't airtight.

EVA Data/Interpretations:

Until now there were no results because there was no solar eruption.

For more details see the EVA report.

Engineering/Hab Maintenance:

Nothing to mention

Plans for Tomorrow:

We will continue our experiments with the algae's. Perhaps one team

will continue the analysis of the surroundig soils.


Support Requested:

Nothing for the moment


We are trying to cook tofu and make it tasty... difficult job :)

Commander's Report

Anne-Sophie Kalbfleisch Reporting

This morning W. de Groot and G. Van Roy made an EVA in order to install the antennae for the radio-telescope. They also connected the spectrom. The ensemble will be used for detecting solar winds (see our website for more information). In the afternoon we started our experiments with the algae. Firstly, we determined the optical density of our sample (as well as the optical signal of the solution without algae that will be substracted from the original signal). We then constructed the ensemble which consisted of two tubes, one filled with water to bring some water vapor in the air for the algae, the other filled with our solution. Both are connected and will be placed in a dark place with light coming from our LED ensemble. We encountered one major problem: our tubes weren't airtight. We will try to repair it tomorrow.

Science Report (Biology)

Wouter de Groot Reporting

Today we worked all the day on the assembly of the experiment in aqueous environment and took our first pictures of the algae on solid substrate.

As you will see in one of the picture Jonas will send you, we have installed the assembly in one of the drawers of the Lab. The assembly is composed of a stative where three LEDs are fixed, we chose the blue ones to start. Then just at the right of the stative is the tube containing the algae solution, this tube is linked to another one containing only water which is linked to an aquarium pump. The pump blows air into the water tube where it will absorb water vapor, then this air in injected into the algae tube to feed the algae in carbon dioxide.

The reason why the picture doesn't show the experiment in action is because at the moment, we didn't succeed in making the top of the fist tube completely airtight, so we can't use it so far and instead injected the air directly into the algae tube.

To make measurements, we use a 40 watt halogen lamp to light the tube and at the other side we have a 750nm optical filter in front of a silicate photo-diode and we measure the transmitted light intensity. The higher the algae concentration will be, the lower will be the intensity detected. We already started the measurements.

1a) Today was

A cooking day

We decided to use milk only for Quaker and bread because of the low

reserve we have.
