Crew 206 Science Report 06-Mar-2019

You’re lucky, today we wrote our first science report of the mission. You’ll have the chance to see our first results !

The attached piece is the graphs of our first week on water monitoring.

1. Microbiological water analysis (Aquapad) : I have done 3 series of 3/4 1 mL aquapads since the beginning of the mission. The number of bacteriological colonies is higher than the sanitary criteria (100 UFC) but lower than the infectious limit (300 UFC). As the water we extract in Hanksville is without a doubt adapted to drinking, maybe the bacterias proliferate in the tank as it is exposed to the sun all day.

Serie 1 : 117 UFC in average after 48h of incubation
Serie 2 : 227,7 UFC in average after 48h of incubation
Serie 3 : 192 UFC in average after 48h of incubation

2. Water Monitoring : For now, our way of monitoring our water consomption is way more efficient than last year Supaero Crew’s (Crew 189). Nevertheless the system can still be improved. We have a new method to do the dishes that is more economical. See attached PDF for numbers.

3. Simulation space suit : It was brought to MDRS to be compared to the actual suits and the conditions of the simulation. They were able to put into light the imperfections of their suit but also its advantages and they oriented the future development process.

4. EVA tracker app : We are still facing issues.

5. Music for plants : The biggest issue is an equipment one : the UV lamp the Greenhab Officer brought didn’t work due to the differences in US and EU electrical system. He used the UV lamp that was in the science Dome which is not powerful enough. The experiment may not work as planned.

6. The human factors experiments won’t be described here in order to avoid bias.
