Crew 183 Science/Astronomy Report

Due to a misunderstanding with Mission Command, I thought that there were two telescopes/observatories, one being currently available for use on the station. It occurs to me now that there is only one observatory, the one that is currently offline.

Refusing to allow my role as crew astronomer to go to waste, I have decided to limit my observations to DSLR astrophotography. I plan on using the view from near the Musk Observatory as a vantage point to improve my astrophotography.

Testing began today on the bicycle-electricity-generator, with promising results. Provided an excellent exercise though.

There are some samples acquired from previous EVAs that I am keen on analyzing in the lab tomorrow, some of which with our 3D scanning system.

Otherwise, today has been rather uneventful as far as science experiments go. Largely focused our time on the midday EVA and producing new designs for the humanitarian 3D printing system.

All the best,

Toluwa Fayemi

Science Report – November 24th

Today we took an extended EVA to survey the area. Tomorrow we will perform and EVA in an attempt to acquire 3D scans on specific, marked, specimen in the area as well as attempting to fly our drone over the Martian landscape.

The rest of today was dedicated to designing 3D models for the humanitarian 3D printing experiment. I have completed the designs for the Doctors Without Borders laptop stand and have redesigned the previous Suction Canister project. Both will be printing overnight with results expected immediately afterwards.
The portion of tomorrow thatI I do not use for our EVA will hopefully be used familiarizing myself with the Solar Observation equipment.
I’m excited for our first day of full sim.

The research project about the effect of Streptomyces spp. strain could not be finished properly. The first problem was related with the lack of medium needed for finishing this project. Nutrient broth and Nutrient agar were the ones I worked with, so there are better results with these. I decided to buy these elements via Internet, but I had to wait a week. After that week, there was little time to start the project. I decided to start working right away, but sadly, the medium ended up contaminated. I will need to check if the transportation of the strain was done properly, though. It would seem that that was the main problem. Maybe it couldn’t resist as much as I expected. Microbiology projects tend to have these kind of problems, though. As a beginner in the microbiological world, maybe I still need to learn some more about microbiology techniques to work an entire project in just two weeks! I will be taking with me some soil samples to Peru. I hope that the enviroment provided by my lab at Lima will help me to finish this project.
Despite the kind of failure of my main project, I managed to learn some things about martian agriculture. First of all, the soil isn’t as simple as I expected. It hardens and it prevents the water to filter through it. It has little to non-organic matter. Somehow I thought that my mere strain could help with these problems, but I realized that this is a problem I will need to adress if I want to finish this (which I will). I tried to search for a technique that didn’t involved mixing two types of soil, but both didn’t work. It seems that in the end I will have to do the mixing.
However, I also managed to do some projects besides my main one. I tried to see the effects of the dishwater on the seeds we had, and I managed to do a nice diagram about some samples and their growth in a couple of days. I also decided to describe the microbes in different plant soils we managed to collect on the EVAs. I’ve been amazed by the shape and forms I managed to get on my plates. I will try to take some of these samples to Lima and process them, to know exactly which microbes are in there.

Hi, Kay!
Hope everything is ok on planet Earth! Peru is playing the football match that could lead us to the World Championship and I can’t really hide how excited I am!
Now, to the important stuff, like the science!
Things in the lab are well. I have confirmed that I can work in a sterilized place and there is no danger whenever I am trying to do my bacteria cultivation, so, thanks to the arrivement of the broth (Thanks, Shannon!) I could start doing some essays on the soil and plants we collected on the vegetative area. My goal would be to have an initial characterization of the microbes living here. I found that interesting.
I have some freaky results I would have to analize later at planet Earth refering to my plants growing in dishwater. I find it surprising that one of the highest concentrations of soapy water could actually be an enviroment for some plants to grow. How are this plants different from the normal plants? Could we use this kind of dilutions to recycle water at Martian habitats? It could be interesting for the future to analize this. I just started that as some side project and now I am asking myself some questions. This is really strange.
As for other projects, my main project will have to wait for a bit more. It seems that the strain I brought has been contaminated. That’s my own mistake, though. Streptomyces can be a pain to work with. So I will have to go back to Peru with some soil to analyze at my lab. I already talked with Shannon about this possibility.
Two crewmembers were working with plants and we noticed how the soil, that has the properties of clay (I could make a cat with that), might be restricting the plant to grow as it dries. We will have to somehow adress this problem whenever we work with the same soil in the future. As for now, I have tried some solutions for this problem.
Geology testings on the soil samples continue to be done at the lab. And we are trying to do the same characterization for the plant soil samples we have.
I will be attaching some photos today.

Mars is pretty nice this night. There’s no cold in our little and warm hab and the night doesn’t seem as cold as ever.

This Science Report should be short because the main reason I’m writing this is because of the ovens at the lab. I’m using a little one and I would like to know if there is a problem with that one. I tried to set up another temperature and it just keeps getting warmer inside and doesn’t really mantain the temperature I originally intended. There are other two ovens, but it seems that they are a lot warmer than I need. I just want to set them up at a temperature near 25 °C.

As for the experiments, they are going well. It seems that the PC plates were well made and we could manage to keep an sterilized condition for making them. I’m expecting a package of Nutrient broth and Nutrient agar and it should be arriving this evening or even tomorrow. It will help a lot for my microbiological experiments.

Today we collected some soil and plant samples on the EVA. Our crew geologist keeps working on their characterization and I could train a bit of my plant systematics. I’m not an expert botanist, but I suppose you need to know a little bit of everything when you’re a scientist on Mars! (I’m learning so much about soils, it’s just crazy). It would be interesting if we get to know the microorganisms that live with these plants. This would be possible with the help of the Nutrient agar (That’s the one we usually use at my lab for this kind of samples).

I have some pretty crazy results on my pilot on the effects of dishwater on my raddish seeds. The ones that are growing the most are the seeds with 10% water and 90% dishwater! It’s really bugging me. I’ll need to follow them to know if they have some kind of alteration during their growing.

Science Report November 9th

Mars has been also great today! We had some sunshine, but it wasn’t as warm as other days. In fact, I had problems finding some sunshine for my seeds. But alright, continuing with the Science report:

The autoclave is already set and working! We read carefully the manual to use this, because I’m particularlly fearful of that machine. But I noticed that it requires a great amount of destillated water for running. I would like to ask about this issue because I had to use a gallon and a half for one sterelization cycle. I’ll need to do another one in the next week, so I would like to know if it is possible to get more gallons of destillated water.

We also need to figure out the position of the machines at the lab. The autoclave requires a good table, so it occupies the only lab table at the lab. I will not be using the hood for my project, so I need to move it somewhere else. Right now, the lab is pretty messy.

As for the projects, there has been some soil sampling today during the EVAs. These samples have been collected for both typing and using during the germination experiments.

No photos are going to be attached to this report, because my main concern is with the destillated water.

Science Report November 6th

Mars is doing pretty fine right now. As the Crew Scientist, I’ll report the principal events of today’s experiments:

Yesterday, we started the germination tests for the raddish seeds. If everything goes ok, then the seeds will germinate in the next 3 or 4 days. This will be necessary for determinating if these seeds can grow.

We recollected soil samples in today’s EVA. It should be enough for one phase of the geology experiment and one phase of the two biology experiments.

The lab is ok, too. We started to relocate some stuff in there, also labeling it. We want to be able to find all the stuff whenever we need it.

We still can’t report any results, though, but hopefully we will have something for the first days of the next week.

As the Crew Journalist, it seems that I will not work that much today. However, I’ll be writing some stuff about todays events in both english and spanish, so please tell me if you would like some of this writings.

As I told the Crew, I love to write, so I don’t have any problems telling jokes via e-mail!

Hope everything is great on Earth!

Science Report November 8th

Mars today has been really great, with bright sunshine and now a cozy hab to sleep in!

Things in the lab have been really great! The germination tests of the raddish seeds are going great. 3/5 in one plate and 3/5 in the second plate have presented a positive response, so the seeds are viable. Raddish seeds are also really fast at germinating, but this new brand we bought is particullarly fast. This will be great for the lab tests.

The new autoclave is now at the lab, and we have plenty of destillated water, so that will help a lot with the different biological experiments. The new microscope is also set up and ready to go! It also incorporates a new cam for our sights in it, so I would like to ask where should I install the drive to use the cam. I fear that this drive is just a one-time software, so if I install it in my computer, it would be the only time it could be installed. That happens quite a lot with other copyrighted softwares. I tried to install it in the hab laptop, but we couldn’t find the cable to connect it.

At today’s EVA, our crew as able to recollect more soil for their experiments. A crewmate is trying to tipify the soil, while other project involves the germination of different seeds in two types of soil.

There’s also this idea some of us had of using the soapy water for some seeds. I’m running a pilot test with raddish seeds. It would be interesting if we find a way of making that dirty soapy water from the dishes useful!

I’ll attach some photos of the experiments in the lab today. The first two ones are from my raddish experiments. The last ones are from the pilot experiment with the dirty water from the dishes.

We also tried to organize the lab better. There are now labels in each drawer and we are trying to set places for the equipment. There is a table for running microbiological experiments and another for geological ones. We are hoping to make the lab a great and ordered space for future crews!
