He finished his code yesterday and he still testing it today.

He also tested the hardware side of the main module as well as mounted and tested 4 of the 7 secondary modules.

2) XO Officer

Finishing and testing the trilateration algorithm of his ultra-wide bandwidth system.

3) HSO Officer Benjamin Flasse

Every morning and every evening, the HSO still gather data about the measurements, weight, brain awakeness, tension and pulse of the crew.

He has now enough data to start analyzing his CFFF-cortical arousal graphics.

4) Crew Astronomer Eleonore Lieffrig

Working on the density probability via the Direct Fourier transform method while coding an algorithm that should allow her to verify the non-dependency of the colloidal particles Brownian motion with regards to the gravity.

5) Crew Engineer Julien Amalaberque

He studied the performance and efficiency of simultaneous location and mapping algorithm depending on the resolution of video streams coming from Intel RealSence D435i camera.

6) Crew Biologist Chloé Peduzzi

Spent the day preparing her Petri dish.

7) Crew Journalist Nathan Pechon

We had a new meeting to talk about the value of life on Mars and how to deal with criminality.

He then worked on his own on different law articles that resulted from in what was said the previous talks. He is glad these debates aren’t sterile but on the contrary, very constructive and animated.

8) Crew Scientist Maxime Bernard

Keeping up with the data acquisition. Some issues are already appearing with the counting statistic.

Science Report 24 April 2019 Crew 211 UCL to Mars Submitted by Science Officer Maxime Bernard 1) Commander Carl-Henrik Dahlqvist The 8 CubeSat cases are assembled and two of them are already functional. He is working on the code to increase the size of the cubelanders network. 2) XO Officer All four antennas are assembled and fixed to the poles. At the moment, he is still working on the software side of the project. 3) HSO Officer Benjamin Flasse Every morning and every evening, the HSO still gather data about the mensurations, weight, brain awakeness, tension and pulse of the crew. In the meantime he is also making an inventory of all the first aid kits to ensure they are all complete and reliable. 4) Crew Astronomer Eleonore Lieffrig Our astronomer managed to take pictures of the sun with the telescope and solar eruptions could be seen. She is also preparing the observation of a quasar using the remote controlled telescope. 5) Crew Engineer Julien Amalaberque No major milestone reach for now. 6) Crew Biologist Chloé Peduzzi The crew engineer and the XO managed to inverse the transformer to allow Chloé to use her LED light for her first sample of spirulina. She also placed a temperature sensor near the spirulina to make sure the temperature will never exceed 30°C. She then started her second experiment in which she is going to plant tomato and bean seeds in different medium composed of different quantities of compost/martian soil with mycorrhiza and/or hydrogel which are going to be dry or not. It will finally constitute a total of 16 different medium. 7) Crew Journalist Nathan Pechon We made a meeting during which he presented the voting rules and the different possible regimes available according to the talks we all had with him earlier. During this meeting we voted for the political regime we thought would suit the best an early martian colony. 9) Crew Scientist Maxime Bernard The detector finally arrived in Hanksville and Maxime together with Shannon picked it up around 6:30 pm.

Crew 211 – UCL to Mars

Submitted by Science Officer Maxime Bernard

Commander Carl-Henrik Dahlqvist

Our commandant started to assemble the structure of his CubeSat that he printed prior to his arrival on Mars.

XO Officer

Simon started to build his wood stands on which he is going to fix his antennas.

HSO Officer Benjamin Flasse

This morning Benjamin gathered the data from the sleep monitoring he did on Eleonore.

Right after that, he measured everybody’s weight, tension and brain awakeness.

In addition to that, he took measures like fat density,bone quality and water repartition intra/extra cellular using Biody Xpert to monitor our body evolution along our stay here.

He spent the rest of the day making the inventory of what was available in the first aid kits. Most of the compresses were outdated and others were opened. The purchase of new medical supplies should be prioritized and more info will be available in one of the upcoming HSO reports.

Crew Astronomer Eleonore Lieffrig

Our astronomer was able to use the solar telescope for the first time today in manual mode.

Crew Engineer Julien Amalaberque

He is checking the parameters of an Intel RealSense D435i depth camera in order to evaluate which amount of stream data the positioning algorithm will be able to handle without being overwhelmed.

Crew Biologist Chloé Peduzzi

She spent the morning one the science dome preparing her culture medium in which she adds strains of spirulina.

She then disposed them in the greenhouse under two different light conditions before realizing it was way too hot in there. Therefore, she instead disposed them into the Science Dome. She encountered another problem we she realized she was sold the wrong transformer, 240V to 120V instead of 120V to 240V.

She went on EVA in the afternoon with three other crew members to gather soil samples.

Crew Journalist Nathan Pechon

Today, Nathan started to ask us questions about what we thought would be a good juridical baseline of a martian colony.

He then worked on the data he gathered during our talks to work on his first law article about what type of political regime should be adopted on Mars

Crew Scientist Maxime Bernard

Still waiting for the delivery of his muon detector that should have arrived on the 19th of April… The parcel seems to be somewhere between Salt Lake City and Hanksville.

Today we continued to process the soil samples taken at each of the 12 transects we conducted over the last few days. In the Science Dome, we measured the pH and salinity and characterized the texture of the soil samples. These data will be used to characterize the ecotones of the deserts around MDRS in an upcoming paper.

We continued to collect new plant specimens opportunistically, including an annual invasive grass, (Annual Wheatgrass – Eremopyrum triticeum) newly recorded for MDRS.

We plan on continuing our lab work and wrapping up data recording for the plant project tomorrow.

Science Report – April 17th

Continuing our vegetation ecology and biodiversity project, we plotted transects and surveyed quadrats at two new sights today: Copernicus Valley and Hab Ridge. As yesterday, we surveyed the vegetation along three transects and fifteen quadrats per site, recording abiotic characteristics and the vegetation of each site.

Additionally, we continued to collect voucher specimens for new vascular plant species encountered at each site, adding 15 new collections and ~5 new species for the MDRS operational area.

This evening we plan on entering data and processing data stemming from these surveys.

Science Report – April 16th

This afternoon crew 210 began to conduct vegetation quadrat surveys as a part of our local plant and lichen biodiversity survey. At two sites pre-selected from the MDRS topographic map (both east of the hab along Cactus Road) we plotted three 10-meter transects, and surveyed five 1-meter-square quadrats along each transect in a zig-zag pattern.

For each transect we recorded GPS coordinates, air and soil
temperature at the center of the transect, measured the height of the tallest plant on the transect, and took a central sample for soil moisture and pH (these latter variables will be measured in the lab tomorrow).

Within each of the five quadrats, we estimated percent cover of vascular plants, and named the top three species (by abundance) inside the square-meter. Any new plant species encountered were collected for identification and to add to our plant biodiversity data.

Tomorrow we will finish the quadrat surveys at three additional pre-determined sites, north and west of the hab, and will continue our plant and lichen collection efforts.

Science Report – April 14th

Sol 2 – Science Summary

Crew 210 sampled vascular plants and lichens from three sites across the MDRS operational area today; the Valley of the Stars, Salt Creek, and the vicinity of the Burpee Dinosaur Quarry. We collected between 15-20 samples, many of which were species not recorded during previous floristic work at the station in 2014. We will press the samples later this evening to preserve them for later identification. Tomorrow, if time permits, we will continue our sampling in the area just around the hab.

3D Printing Projects

Today is the last full day of MDRS for myself and our crew HSO. Our 3D-printing experiments continue to progress. We have completed printing all of our labware, International Space Station medical inventory items, STEM teaching aids, and are now printing some things here and there around MDRS, as well as other miscellaneous 3D printed projects.

To date, we have printed:

1. Western blot combs (18 well combs for making gels)
2. Microscope slide holder (reusable holder for square coverslips)
3. Sieve mesh (2.0mm holes)
4. Sieve structure (for holding the mesh net)
5. Mobile phone microscope clip
6. Sample box (for 96 tubes)
7. Stackable freezer bin
8. Salt spray chamber drain
9. Triangular straws (in a rainbow of colors)
10. Sieve mesh (5.0mm holes)
11. Sieve structure (for holding the mesh net)
12. Slide box holder (for storing microscope glass slides)
13. Test tube rack
14. Test tube holder
15. Sample rotator components
16. Small test tube holder (for the freezer)
17. Heat gun nozzle mount
18. Tongue depressors (in a rainbow of colors)
19. Stoma bag clip (used as a chip bag clip)
20. Full set of fraction tools (mathematics educational tools)
21. Funnels (small, medium, large)
22. Construction blocks
23. 12 tube separator (for Eppendorf tubes)
24. The side part of thoracentesis trainer
25. Customized finger splint (originally printed on the ISS0

During our time at MDRS, our 3D printed straws proved incredibly useful for our crew members. It has helped greatly in our attempts to reduce our water consumption. At MDRS, we have also demonstrated that a number of our 3D printed labware items are functional – as validated by two basic science research students.

Even though we will be leaving tomorrow morning, we will continue to stay in contact with our MDRS crew members and send 3D printable files for incoming crew members to print! (Perhaps some reusable bubble tea straws?)
