EVA #3 12-22-1022

Author: Cesare Guariniello

Start time: 09:00

End time: 11:25

Narrative: The Crew Geologist Helen, with the support of the Executive Officer Cesare, set up a soil wetting experiment: after selecting an appropriate clay-rich area, she mounted a shaft to hold the probe of an ASD Visual and Near-Infrared (VNIR) spectrometer. First, the crew took a spectrum of the dry soil. After wetting the soil with 1 liter of water, Helen took initial spectra 2 minutes apart, then 3 minutes apart, 5 minutes apart, and 10 minutes apart, over the course of 2 hours, to measure the evolution of the spectra during the drying process. The EVA ended when the battery of the field laptop ceased working.

Destination: North of Hab

Coordinates: N4250800, E518300

Participants: Guariniello, Eifert

Road(s) and routes as per MDRS Map: Walk around science dome to the North

EVA #4 12-21-2022

Author: Cesare Guariniello

Start time: 13:30

End time: 16:00

Narrative: First, the EVA crew walked to the location of the geology experiment set up in the morning and took another reading of the spectrum of the drying soil. Then, they selected the two rovers with the highest status of charge (the rovers were kept unplugged to preserve energy from the generator). The crew drove to the intersection of the Main Road (Cow Dung Road) with Hwy 1101 and troubleshot radio communication: due to the high power of the repeater but relatively low power of the portable radio transmitters, part of the crew could hear the other crewmembers but could not transmit. The crew switched to simplex mode on channel 2, checked proper communications, and began walking towards Barrainca Butte. Two objectives were pursued in this EVA: first, the crew collected potentially igneous samples in the southern side of MDRS region, and samples fallen down from the higher layers in Barrainca Butte (Dakota sandstone); second, the crew performed two radio communication checks with the habitat via the repeater installed on Hab Ridge. Upon returning to the habitat, the crew took another measurements of the geology experiment, and left the rovers unplugged, to preserve energy.

Title: Marcaroni & Spectroscopy

Our first full day on Mars was eventful, extra emphasis on the EV. In the morning, Guariniello and Eifert conducted a nearby EVA north of the Hab for Eifert’s research project. Using a high-tech watering can, we executed the exciting task of watching dirt dry. I estimate this to be about 10% more invigorating than watching paint dry. Granted, on Mars it is actually called regolith and not dirt, but I fear the use of fancy terminology may oversell it. Between measurements, we leisured in our EVA suits, read books, and sketched the landscape. The real excitement will be in the analysis of the squiggly line outputs gathered by our efforts. In fancy terms, we call this spectroscopy, but that may undersell the excitement. Some technical difficulties cut our first EVA short, providing enough time for some lunch and work in the Hab before heading out for a second EVA.

As the martian temperatures continued to rise, Guariniello and Eifert suited up a second time, this time joined by Koasaar and Grete. For our second EVA, the IMARS crew endeavored south of the Hab to Barrainca Butte in the Curiosity and Opportunity rovers. We did indeed touch the butte. Here, we found much more compositional variability in the geology and gathered hand samples for Cesare’s research. Much like our morning EVA tasks, these samples will be returned to the Hab to dry in an oven. More squiggly lines, repeat.

Speaking of squiggly lines, it wasn’t rigatoni, fusilli, or farfalle, but elbow macaroni promptly prepared for dinner by our commander Marc. To satiate the hungry bellies of four astronauts, Macaroni a la Marc or marcaroni, came chock full of cheese, vegetables, and tuna. Yes, mama Guariniello, not only did Cesare eat Mac & Cheese with fish, but he added extra parma on top. The shelf stable parmesan at that. We’ll be sure to promptly remove his Italian flag from his flight suit. Our MVP commander baked another fresh loaf of bread with dinner even after tolerating our comm chatter all day. Last night, Marc even treated us to photos from his winter over at the South Pole and today our ears were graced with the sounds of the South Pole’s Broke Dick Blues Band, Levesque lead vocals. An evening meal that truly tickled all the senses.

Before I close out my account, I would be remiss to not mention the hard work back on Earth by Shannon to get our generator back to nominal, with the station support of our HSO and crew engineer, Sergii. Without it, we wouldn’t have our inflatable holiday baby Yoda. Priorities.

Summary Title: Field work

Author’s name: Marc Levesque, Commander

Mission Status: Nominal

Sol Activity Summary: The crew completed two EVAs today. The first was a short walk north of the Hab in the morning to take measurements at Eifert’s project site. Later that morning, a longer EVA was planned to reach the southern rim of Lith Canyon via the Burpee Quarry as part of the communications project. Because of rapid battery drain likely due to the cold, the EVA team had to leave the rovers at Brahe Highway and walk to the Quarry, resulting in a shorter walk than planned. Communication checks with the Hab were made along the way to determine if the heightened repeater antenna reached these areas.

Look Ahead Plan: Two EVAs are planned, a short one in the morning for Eifert’s project, and a simulated drone recovery exercise northeast of the Hab.

Anomalies in work: None

Weather: Warmer and mostly sunny

Title: Grease Lightning

To celebrate our first full day in sim last night, the IMARS crew watched The Martian for a movie night. With an analog astronaut crew full of real aspiring astronauts, we were all left stewing on the science and wonders of real space travel. Our EVA requests were submitted, with every crew member getting a space walk. Luckily, no potatoes were needed today.

In the morning, Guariniello and Eifert returned to the experiment site north of the Hab for additional measurements. The clay rich environment still appears wet a full 24 hours after saturation. The squiggly lines should confirm what we see with our eyes in the form of a key absorption at a particular wavelength of reflected light. This elbow macaroni shape alerts us water has made its way into the chemical structures of the surface material. We collected a dry sample nearby so that we may better understand the initial water content and how long it takes for our experiment site to return to equilibrium. A short and sweet EVA that nearly ended in disaster when Sergii almost blew out the airlock before depressurization was complete. Danger is ever present in space, so heed my warning not to coordinate a stadium wave in the airlock because it may mis-alert the crew on station.

After our short EVA, I spent the rest of the day holding down the Hab with Cesare. The remaining crew members took a long rover drive out towards Lith. The whole EVA was described by Grete as an “exertion excursion” since the rovers didn’t make it the full distance to their destination. The four astronauts continued on foot for many kilometers testing the comms. Commander Levesque, a licensed amateur radio operator, recently set up a repeater west of the Hab to improve radio communications amongst astronauts for long distance EVAs. The findings are in and improvements are needed. The fun fact of the day is that the background static that disrupts radio chatter is referred to as “grease.” The chicks do not scream for this grease lightning, but it did give us a great excuse to call each other greasy all day. Apt, given we are at Sol 5 and our water consumption has been low enough to afford some much needed showers this evening. Solving two grease problems in one day here on Mars.

Something that was not greasy, was the beef stew cooked up in the Hab throughout the entire second EVA. With tomato powder, freeze dried beef crumbles, dehydrated veggies, bouillon granules, and potato chips, we enjoyed another successful day on Mars with a healthy, hearty meal. Guess we needed potatoes after all. Cesare baked another loaf of bread to pair with the stew. Fresh bread does not last long on station, particularly when baked with parmesan and fresh herbs from the GreenHab, courtesy of Alicyn. All of her pull-ups are paying dividends for herculean harvesting of epic proportions. She has the strongest green thumb I’ve ever seen, putting inflatable baby Yoda to shame.

If you are wondering how many astronauts it takes to do a jigsaw puzzle, the question is moot. We finished two puzzles in under two hours with speed and precision. Andres, crew researcher and resident psychologist, notified me that our crew cohesion levels have increased one point today. I am suspicious he is only saying this so we cease our threats to chop off his dreads and shave his mustache. Can you blame us, though? NASA hates fires, so we’re dead set on minimizing all the grease we can muster. No hair is safe on Mars.

EVA #6

Author: Marc Levesque

Purpose of EVA: Long-range communications check

Start time: 1100

End time: 1355

Narrative: The EVA team intended to drive to the parking area at the Burbee Quarry and then proceed on foot to a point on the southern rim of Lith Canyon. Because of a rapid battery drain, the rovers had to be left at the intersection of Cow Dung Road and Brahe Highway, from where the team proceeded on foot only partly into the canyon before returning to the rovers. Prior to reaching the intersection of Brahe Highway and during the foot travel, all communications checks with the Hab failed, including the use of a mag mount antenna on one of the rovers.
