Crew 186 Geology Report 02JAN2018

The plan of today’s EVA included the two locations that were not visited yesterday: the area East of Greenstone Rd and the area between Robert’s Rock Garden and Zubrin’s Head, both in the Morrison formation. During the drive outbound, the crew geologist gave a short introduction to the other EVA members, who had not participated in the first EVA.
The crew spent a long time in the field, and the geologist was able to select, analyze, and collect various samples of clays in different strata of the Morrison formation. The search for hematite spherules was only partially successful, with two potential candidates found in the second site. The geologist also recorded temperature of the samples, for later analysis of thermal inertia of the material. The problem with the portable spectrometer is currently being addressed by personnel at Purdue.

Science: Geology.

The goal of the geologic project of Crew 186 is testing the use of remote sensing to identify suitable minerals for In-Situ Resource Utilization (ISRU) and to analyze their physical properties for collection and use. Thus, several geology EVAs are scheduled, focusing on materials that are found on locations of geological interest on Mars.
The plan of today’s EVA included three locations, all within the Saltwash and Brushy Basin members of the Morrison formation, South and Southwest of the habitat: the area between URC South Site and Kissing Camel Ridge, the area between Robert’s Rock Garden and Zubrin’s Head, and the area East of Greenstone Rd. The crew geologist gave a short brief to the rest of the crew (a more in depth introduction to the geology of the area is scheduled for tomorrow), and instructed them on the type of samples to be collected during the EVA: different types of clays in the first two locations, and hematite inclusions (spherules, or “blueberries”) in the third one.

Due to delays in the first phases of simulation, the EVA started later than planned, and was consequently cut short. The EVA crew members reached only the first location, and upon directions by the geologist found appropriate samples. The samples were photographed and analyzed with the TREK portable spectrometer. Temperature of the samples was not recorded, due to the reduced duration of the EVA. The samples collected today were a chlorite sandstone, illite/hematite soil, a montmorillonite mudstone, and a clays conglomerate. Once back from the EVA, we reviewed the spectra of the samples, comparing them visually with the USGS library spectra; however, it was not possible to download the data from the portable spectrometer to a laptop, due to a software error which has not been yet been solved. We will work on the connection problem tomorrow, or failing that, all the analysis can be performed after we return to Earth.

HAPPY NEW YEAR

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/Astronomy Officer

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.

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.

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.

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!

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!
