Anomalies in work: Nope.
Weather: 6 C, 43 F

Support Requested: None.
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!

Notes and Comments:
Last night was a little cold, we are having problem with the heater., because when we turn it on, it heats, but few hours later the air is cold again. So, we have to turn it off and then turn it on again to keep us warm. Do you know a solution for this problem?
At the same time, we did an EVA session today. The blue moto is not working. In that way, we did the EVA session with the deimo and the red moto. We do not had any problems with these vehicles. In contrast, we had problems with the radios. All radios are working, however, approximately 2.5 km far from the Hab, we could not had any communication with the Hab. We do not know why that is. So, please send us the ratio of distance in which we could keep the communication.
Tomorrow we are going to use the solar.
We started EVA at 1:35 PM, instead of the planned 1:00 PM. The delay was due to an extended period for our ATV training to take place. The EVA crew included myself, Carmen, and Atila. Drove north and spotted vegetation growth along road and marked the location. We tried marking the location with a GPS, but we found it was impossible to read off the screen with the helmets on, since the screen was too scratched up. Instead, I determined the coordinates by closely examining the planning map after the EVA. We Took several pictures of the area along with the surrounding terrain
We continued north and passed Tank Wash due to navigational Error. We ended up taking the road all the way to the Quarry Site. We retraced our steps southward until we found the reservoir dam, which was the most distinguishable feature I could use to place our location.
-Stopped at coordinates:
We then slowly drove northward, until we found the correct wash
-Stopped at coordinates:
We made our way to a talus slope that contained broken down rock from the cliff above us. Upon digging through the cemented layers, we found three distinct layers within only 20 cm below the surface.
– Coordinates of Sample Location #3:
There was a white-colored layer in the first 7 cm, then a green layer below it that was 3-4 cm thick. Below that was a dark brown / black soil lightly peppered with white grains. We collected samples from each of these layers and photographed the area and our activities. We loaded up our samples and returned to the hab. Before we entered the airlock, Carmen checked the Diesel and Propane tank levels. We began recompression in the airlock by 3:45 PM.
For the next EVA, we need to improve our radio Comms. I’ll instruct the crew members on words and phrases to use on the radio, such as “affirmative”, “negative”, “over”, “loud and clear”, etc. Also going over the phonetic alphabet may come in handy. In order to reduce the chance of another navigational error, I’ll have to take very special notice of the surface features surrounding my intended destination before we depart. I’d also like to request obtaining another GPS device that we can read on the field so we can record our sample locations in the future.

Sol 5 was a pretty lazy day at the Green Hab (GH). Yesterday I worked till 22:00 at the GH and then I was looking for some guides to build a homemade Drip Irrigation System, so I woke up pretty late, plus we had the training for the Rovers and the ATV’s and a 3-hour EVA. It all went awesome! But I didn’t have time to make the repairs I wanted to make on the GH. However, I did repair the GH door that I discovered was a bit lose.
During the last hours of Sol 4, I finished the preparations for my project. Half of the seeds remain at the GH; the other half is in the growing chamber that’s on the Lab. For all the experiment I’m using less than a liter of distillated water per day.
The project wants to prove that Peruvian native crops can, indeed, germinate and grow on Mars soil. I’m working with quinoa, amaranthus and mustard (as a control).
I’ll attach you a picture of the pots!
As I’m aiming every Sol, tomorrow I’m going to rearrange all the GH, because it’s a mess. I’ll let you know how that worked.
Support/supplies needed: none
