End-of-Mission Research Report – Crew 315

Summary of Crew Research Projects:

Title: Methodology Extending Mobility Range on Mars

Principal Investigator: David Laude
Description: Mobility on Mars is key to any mission for maximizing scientific gains. Main mobility for humans is motorized rovers with limited range. Mobility can be extended for examination of more remote objects. Objects of interest can be observed from rover accessible vantage points. Two observations can be used to triangulate object position (no GPS on Mars). Position can be found or placed on map to determine travel range. If range is beyond rover range, but within rover + foot + drone range then range can be extended by foot and then deploying an FPV drone/helicopter. Drone can collect close up HD photos.
Objective: An EVA team will set out on EVA with a small drone equipped with HD camera and FPV capability. EVA team will follow a planned course from maps. When rover is at maximum range (real or simulated), EVA crew will set out on foot with drone. Once EVA crew is close enough to the object, the drone pilot will launch it. Drone pilot will fly drone in full sim suit while drone spotter(s) stand nearby. Drone will acquire the needed object images from close up Image data will be retrieved from drone in Hab for analysis to determine if mission was a success. Project methods will be reviewed for success or needed improvements
Research Summary: The project has completed with a close encounter with the Monolith objective by drone after having triangulated its position from two vantage points and placing object on map. From that we plotted a course by rover as close as we could get followed by a short hike up a hill where the drone was launched. This shows the usefulness of the methodology for examination of remote objects further than one would ordinarily expect.

Title: Evaluating Drone Piloting During EVA on Mars
Principal Investigator: David Laude
Description: With the success of Ingenuity paving the way, piloted drones will undoubtedly be used by humans on Mars. The purpose of this project is to study drone piloting with EVA suit and to evaluate any operational impediments. Co-investigators will evaluate drone flight control performance on standardized flight patterns, making use of URC fields and possibly other locations. Co-Investigators will rate each flight through several metrics. No EVA suit flights will take place prior to and/or just after sim.
Objectives: Metrics like accuracy (measured distance to center of target) and speed (time) of flying drone to marked targets of varying ranges will be evaluated via comparative analysis. Comments on difficulties experienced will also be documented.
Research Summary: This project is completed. It has shown what one would expect for piloting a drone in EVA suit. Poorer visibility in EVA can cause temporary loss of drone sighting by both naked eye and FPV display. Displays need to be brighter. In addition, the wearing of gloves impedes fine drone control.

Title: Illustrating a Mars Analog Mission as an artist.
Principal Investigator: Timothy Gagnon
Description:In March 1962, NASA Administrator James Webb addressed a two-paragraph memorandum to NASA Public Affairs Director Hiden T. Cox about the possibility of bringing in artists to highlight the agency’s achievements in a new way. In it, he wrote, “We should consider in a deliberate way just what NASA should do in the field of fine arts to commemorate the … historic events” of America’s initial steps into space.
Shortly thereafter, NASA employee and artist James Dean was tasked with implementing NASA’s brand-new art program. Working alongside National Art Gallery Curator of Painting H. Lester Cooke, he created a framework to give artists unparalleled access to NASA missions at every step along the way, such as suit-up, launch and landing activities, and meetings with scientists and astronauts. Over the years, NASA artwork has helped spark national pride and accomplishment. Technology, whether from the 1960s or today, documented these missions extensively, but artists are able to pull in emotion and imagination unlike data-collecting machinery. The relationship between science and art continues to inspire the public and inform us of current missions. When I was invited to participate in a MDRS analog mission as an artist, I immediately thought of contributing the same way as the artists involved in the NASA Art Program of the 1960’s and 1970’s.
Objectives: To document my experience and that of my crew mates by creating digital and fine art of our increment. I have already designed our mission patch, our crew portraits and a "Space Flight Awareness" themed crew poster. I intend to bring my iPhone camera, possibly my iPad as well as a sketch pad along with pens and colored pencils to sketch while there and then turning those into finished art post mission.
Research Summary: Due to the limited field of view offered by the suit helmet and the limited dexterity of the gloves, sketching during an EVA proved impossible. However, I was able to take and request certain photos inspired by the Apollo lunar missions and paintings by artists I admire to create tributes to those missions and those artists. This was accomplished during four EVAs of mine and multiple EVAs by my crew mates. Together we have assembled a portfolio of photographs that will be the basis of a series of art pieces based on the theme, “What it looked like vs What it felt like.” Analog vs Artemis missions to Mars. I will donate those pieces to The Mars Society to hopefully use in their fund raising efforts.

Title: Essay for Harper’s Magazine

Principal investigator: Elena Saavedra Buckley

Description: The primary reason for my visit to the MDRS is to write an immersive, in-depth reported essay for Harper’s Magazine, to run as a feature at some point later in the year. This piece is assigned at Harper’s, where I am an editor, and has been approved by the MDRS via Michael Stoltz, the media and PR liaison.

Objectives: The aim of the article is not only to capture the experience of our mission, but to zoom out and consider the purpose of Martian simulations, of eventual Mars missions, and the place these phenomena have in the American imagination today.

Research Summary: My reporting went well, and I was able to talk individually with my crewmates and with everyone as a group multiple times. I’m excited to bring all my reporting to Earth, continue my research, and put it all together in 1g.

Title: Examining oyster mushroom growth in a Martian greenhouse environment

Principle investigator: Elena Saavedra Buckley

Description: Mushrooms are an easy to grow, nutritious source of food that can be transported in remarkably compact ways. (Beyond culinary uses, fungi structures are strong and lightweight, and NASA has studied the feasibility of using them for Martian architecture, or “mycotecture.”)

Objectives: Use a pre-made grow kit to grow oyster mushrooms in the Greenhab to gain information on possible hiccups and problems with mushroom growing in a sealed, arid environment; and, ideally, eat them.

Research Summary: Sadly my mushroom kit has seemingly failed. I sprayed it regularly and installed a humidity tent, and I followed all kit directions, but the “pins” never formed. Technically they could form in the next few days, but it’s more likely that the conditions were too hot or dry for blue oysters. Green mold did start forming on the exposed spores, so I imagine that indicates some kind of decay.

Title: Measuring soil desiccation patterns near the MDRS

Principle investigator: Elena Saavedra Buckley

Description: Desiccation cracks in soil form as moisture evaporates, leaving behind polygonal patterns that have been observed in terrestrial desert environments. On Mars, these features provide insight into past hydrological conditions, soil composition, and potential habitability. By studying desiccation patterns in the Mars-like environment of the MDRS, I will better understand how similar features on Mars might have formed, and learn more about how soil evaporation occurs.

Objectives: Measure various soil desiccation pattern areas and, in the science dome, do a simple experiment on soil samples to see how long cracks take to form.

Research Summary: I collected five diverse soil samples from around the MDRS—ranging from gravel to clay—and measured variables regarding their desiccation powers in the field. In the Science Dome, I mixed consistent amounts of soil and water and packed them into petri dishes, where I placed them in the GreenHab (in order to get accurate temperature and humidity readings); the majority desiccated over the course of two days, with two samples not yet desiccating, suggesting that their desiccation patterns in the field required either drier conditions or more surface tension. I will write up the comparisons between the spread of measurements in the field and in the patterns in the lab and further analyze how the soils’ conditions related to their desiccation speeds.

Title: EVA Connectivity Kit
Principal Investigator: Michael Andrews
Description: By combining commercial off-the-shelf products, I developed a portable kit that can be taken on EVAs to provide internet connectivity to crew members. This has various benefits: sending data back to the station, enhanced communications, and en-situ research while on EVA. Objectives: Over the course of 3 EVAs, confirm efficacy of kit and measure its performance parameters: battery life, upload speed, download speed, weight.
Research Summary: I have been able to demonstrate that a Starlink mini and 20,000mAh battery pack can be easily carried and deployed on an analog EVA. Over the course of 5 tests and 3 EVAs, an average expected life of 171 minutes, download speed of 140 Mbps, and upload speed of 14.5 Mbps was observed. I was able to regularly bring this kit on future EVAs to support the crew and my 3D scanning project’s objectives.

Title: 3D Mapping of Samples
Principal Investigator: Michael Andrews
Description: To prevent physical extraction of geological samples on EVAs, I demonstrated 3D mapping technology as a way to create "digital twins" of specimens. This will also include engineering hardware on station.
Objectives: Determine how quickly samples can be recorded in station and on EVA, including sending them to the station via the Connectivity Kit above.
Research Summary: Over the course of six EVAs, I was able to collect samples to return and scan in the Science Dome and scan samples en-situ using my equipment. I scanned a total of 14 samples, 3 of which were en-situ (see Figure 1). The samples were a variety of colors and textures, and ranging in weights up to 610g and lengths of 6.25”. The activity would first take me up to 2 hours per sample, but I have determined a technique (one geometry scan and two texture scans) to construct the EVA shroud in 9 minutes and perform all scanning operations in 35 minutes. The output file (.obj file type) can quickly be shared to a Google Drive via Starlink and be viewed by other crew members in the station while the EVA is ongoing.

Title: 100cameras Method: Photography as a Tool to Mitigate Psychological Stress in Space

Principal Investigator: Urban Koi, HSO

Project Description: Space exploration presents unique psychological challenges for astronauts, particularly during long-duration missions where isolation, confinement, and distance from Earth can lead to significant emotional and mental stress. As humanity advances toward becoming a multi-planetary species, addressing these psychological effects is crucial for the success of future missions to the Moon, Mars, and beyond. Developed over 15 years of research and practice, the 100cameras Method leverages photography as a dynamic tool for self-expression, fostering emotional intelligence, resilience, and community-building skills. The 100cameras Method has been recognized by the United Nations University Centre for Policy Research (UNU-CPR), UNIDIR, and UNICEF for its positive impact on empowerment globally. By integrating the 100cameras Method into the daily lives of analog astronauts, we aim to provide future astronauts with a structured yet flexible approach to document their experiences, process emotions, and strengthen connections with their environment and peers, combating the psychological effects of space travel.

Objectives: (1) To evaluate the effectiveness of the 100cameras Method in enhancing emotional intelligence and resilience among analog astronauts. (2) To assess the impact of photography-based self-expression on the well-being of individuals in isolated or extreme environments, such as analog and space missions. (3) To analyze the potential of the 100cameras Method as a scalable intervention for various populations facing psychological challenges. (4) To integrate the 100cameras Method into future astronaut psychological wellness toolkits.

Project Completion: Crew Phoenix (MDRS-315) has successfully completed 8 of 8 modules. All MDRS-315 Analog Astronauts are now 100cameras Graduates and have the 100cameras Method in their Psychological Wellness Toolkit for future missions in Isolated, Confined, and Extreme Environments. Congratulations to Crew Phoenix!

(1) Introduction: 100cameras Overview + Pre-Course Survey.

(2) Composition & Storytelling: Composition Techniques—Telling A Story, Leading Lines & Vanishing Point, Repetition & Patterns, Symmetry, Point Of View, Rule Of Thirds. Each crew member captured 10+ images pertaining to the module exercise.

(3) Camera Tool-Belt: This module focused on teaching analog astronauts how to capture the moment and the story as they see it best. Through learning the camera equipment and its functions, analog astronauts learn techniques such as exposure, aperture, and flash. Each crew member captured 10+ images pertaining to the module exercise.

(4) Range of Feelings: The activities showed that stories can be told in a more compelling and engaging way when practicing the different composition techniques and when utilizing the tool-belt techniques to adjust the camera to work best within the environment at hand. This module focused on how different feelings and emotions can be expressed through photography, enabling a fuller narrative to be communicated and experienced through images. Each crew member captured 10+ images pertaining to the module exercise.

(5) Something of Me: This module focused on exploring how a portion of a person’s individual stories, such as their interests, experiences, circumstances, and ideas can impact how someone sees themselves. It’s a guide to explore some of the pieces that make each person who they are as individuals and relate to how stories are shaped by these elements. Looking inward and spending time with oneself can influence how a person sees their own story and perspective—and how they tell it and share it. Each crew member captured 10+ images pertaining to the module exercise. Each crew member captured 10+ images pertaining to the module exercise.

(6) Map My Story: Through the "Map My Story" exercise, crew members considered the past, present, and where the future might take them by illustrating a life map. They reflected on who they are today because of their past experiences and how these experiences have helped to shape them. Crew members were encouraged to envision and dream about their future and who they want to become.

(7) Portraiture: This module focused on how all of the tools that have been learned thus far can contribute to creating photos that reflect the journey as well as the inner self through portraits and self-portraits. Crew members participated in activities that help explore different ways to portray themselves and others through photography, both in direct and abstract, creative ways. Each crew member captured 10+ images pertaining to the module exercise.

(8) Your Role in the World: This module focused on how to tie together multiple photographs to tell one cohesive story. Crew members created a “portfolio” or group of images which relate to one another, rather than one single image by itself. Crew members engaged in activities that help practice creating a “Central Theme” portfolio.

(9) Graduation: EachMDRS-315 crew member graduated and received a 100cameras Certificate of Completion.

Mission Summary- May 2nd

Mission Summary

Mission: 315 (Phoenix)

Dates: April 20 – May 3, 2025

Author: David Laude (Commander)

Being a Mars Society crew, we had nearly no previous knowledge of one another, making for an unknown compatibility outcome. As the Zoom meetings progressed it became apparent that this crew could work together in harmony and become friends along the way. Over the course of months, the crew was informed, guided, and educated by the experienced Commander. In the end, with the crew’s diligent work, everything paid off in the form of a fully successful and pleasant mission for all.

The crew is composed of Crew Engineer Michael Andrews, who works in aerospace logistics and is a veteran of the Mars Arctic Research Station; Health and Safety Officer Urban Koi, who is a Space Systems Engineer and student of Space Medicine, and while at the MDRS received a grant from NASA for a project where she is PI; Crew Artist Tim Gagnon, who designed many of the patches for Space Shuttle crews; Senior Editor Elena Saavedra Buckley from Harper’s Magazine as our Crew Journalist; and Commander Dave Laude, on his 6th MDRS assignment and who has previously been Engineer, Executive Officer, Journalist, and Commander. Our Crew Journalist will write a lengthy article for Harper’s Magazine about our mission that will be published later this year. We had nine research projects in total to perform.

“Also Sprach Zarathustra” ("Thus Spoke Zarathustra") by Richard Strauss in the late 19th century and made famous by the 1968 movie “2001: A Space Odyssey,” was the first music piece heard while awaiting depressurization in the airlock when the mission commenced shortly after noon on April 21st. Our Journalist was the first of us to set foot on this dusty red globe making its way around an orbit not the least affected by our meager presence on this world. Other music pieces were played on subsequent EVAs, helping to pass the 5 minute air lock time intervals. With no sound those 5 minutes seemed like 20.

Since most crew members had never traversed the analog Martian regolith before, it was especially important to familiarize themselves with the procedures of the MDRS Campus. During the beginning of the mission, the crew became acquainted with the expected duties of their roles, way around the campus, use of radios, and operation of the EVA suits and rovers.

The Phoenix Crew quickly became accustomed to their Martian home, as the sols gradually became more habitual and routine. Mornings started with coffee, breakfast, and then the 8:00 AM daily planning meeting. By 9:00-9:30 we had the first EVA of the day started, then lunch, followed by afternoon EVAs. Arrivals to the hab after an EVA were frequently greeted by the smell of baking bread or dinner cooking. We were so fortunate to have three talented chefs who made a variety of great dinners from mostly freeze dried food. The Commander while on Zoom spoke of the great food possibilities with freeze dried, and he even submitted some photos of past meals, but the crew was still pleasantly surprised over the outcomes. The chefs made use of micro-greens, herbs, and cherry tomatoes from the Greenhab.

Here is a list of our interesting and diverse projects by title. For more detail, see the many other mission project reports.

The entire crew took a special liking to the Commander’s “Methodology for Extending Mobility Range on Mars” project, as the object of the range extension was a massive monolith sitting on a broad flat area. It was extremely unusual in appearance and appeared to change color from black to light colored like its background which tended to hide it. This could at best be seen in the far distance with the naked eye, but the project provided the means to get within about a kilometer of it by drone after driving rovers as far as possible, walking towards it, and then releasing the drone brought by the HSO. The closest photo of the Monolith reminded the Commander of a bird, with wings spread and head held high—perhaps a pose our Phoenix could do and thus was named the Phoenix Monolith. This mysterious object will somehow be a subject of another crew with our Commander.

Some evenings we had a few hours of free time and watched Moonbase 8 mini-series. The Commander brought some historical technological artifacts from the 20th century for a show and tell that included magnetic tapes, punch cards, electron tubes and discrete transistor circuit boards. One night he played his MP3 recording of his “Sunrise from Olympus Mons” opus (music).

As in any remote station, there were maintenance activities that included fixing EVA suits and batteries, dealing with power interruptions, broken tunnel zip ties from wind damage, and more. The engineer made sure that the Hab was functioning nominally by monitoring and emptying the toilet, calculating water levels, and inspecting the station’s facilities in the midst of uncertain power supply.

By any standard the mission was a complete success, if not a great success. CNBC sent a videographer for a special project to be shown on public media regarding human’s readiness for a Mars expedition. Sadly, the mission ended in intense preparation to leave this unique experience and place, completely upsetting and ending sim. A feast at the local Duke’s Slickrock Grill in downtown Hanksville celebrated the success. Fortunately for the Commander, another mission has been approved with him one year from now on Crew 335, and the Crew Engineer will soon be headed back to Flashline for a week of renovation and maintenance.

CREW 315 SOL SUMMARY REPORT 02 MAY 2025

Sol: 12

Summary Title: End of Mission but boy was it something!

Author’s Name: Tim Gagnon – Crew Artist

Mission Status: Nominal. All systems operational.

Sol Activity Summary:

The sunrise this morning was beautiful and bittersweet. We knew this would be the last day of a mission we had looked forward to for a year. We hope the 315 crew “raised the bar” for future analog crews. All of our goals were met and although some experiments were unsuccessful results were still educational.

We gathered around the table enjoying a continental breakfast of coffee and sweet breads. At 8am our Commander opened the meeting to discuss the plan to host CNBC. The Commander would host the tour of the Hab first floor where the spacesuits CapCom station and airlocks are. The Artist would host the tour of the second floor residence, the Engineer would host the tour of the RAM, the Journalist would host the Green Hab tour and the HSO the Science Dome.

Lucas Millikan, the videographer from CNBC arrived shortly after 9am was met by Mission Support and “shot B-roll” of the MDRS campus. He entered the front airlock and went through the five minute procedure to transition from outside atmosphere to Hab atmosphere. We all greeted him and the Commander conducted a brief tour of the various facilities as an introduction to the base. We then adjourned to the second floor residence for an introductory meeting.

The Commander, as is customary took the first interview via Zoom with the producer in NYC. In a change, the Commander conducted the entire detailed tour but individual interviews were conducted with the entire crew in the above assigned locations. When the individual interviews were completed, the Commander, Engineer and Health and Safety Officer took Lucas on an EVA to Galileo Road where the HSO will pilot her drone to Compass Rock and the Engineer will show his ability to remote 3D scan of rock samples. During the EVA CNBC interviewed the crew asking about the suit, their experiments and the location. While they were gone the Journalist and Artist completed the take down of the Green Hab for closure over the summer off season.

When they arrived back at the Hab our analog adventure came to an end. Once final photos were taken we doffedour flight suits and along with Mission Support went to Dukes Grillin Hanksville for a celebratory dinner.

LOOK AHEAD PLAN: As a child of Apollo, I approached this mission with the idea to share how the lunar missions of my childhood offered inspiration to this experience. It is only fitting that I quote the Commander of Apollo 17 as he ended the last mission of the Apollo lunar exploration program. He said:

“As I take man’s last step from the surface, back home for some time to come, but we believe not too long into the future, I’d like to just say what I believe history will record: That America’s challenge of today has forged man’s destiny of tomorrow. And, as we leave the Moon at Taurus-Littrow, we leave as we came and, God willing, as we shall return: with peace and hope for all mankind. – Gene Cernan.

Crew Physical Status: All in Good Health + Spirits

Journalist Report – May 1st

Journalist report sol 11

At 10:30 pm last night, our HSO heard the clang of our mousetrap and sprung into action with blue painter’s tape. The mouse was still in his cell by morning, with the bait of funfetti cake crumbs turned into dust by his reasonable anxiety. Before we could take him outside, we had a chatty breakfast while discussing tomorrow’s visit from CNBC, as well as technical things like mission summaries, GreenHab teardowns, and Hab clean-ups.

At 9, the Millennial EVA Crew (Engineer, HSO, Journalist) went to Candor Chasma and began the EVA by releasing the mouse. He had become strangely wet in his cage. He fell, cowering, out of the trap and darted behind a bush, and we saw him bound up the nearest tall hill and crest over its edge with Looney Toon speed. We wished him well and hoped that last night’s rains would give him a head start, and then we descended into the riverbed and hiked through the soft sandy floor. The HSO hoped to use her drone to weave in and out of the canyon, but after some attempts it seemed that the dust and many flights had gotten to it. (Some canned air back at the Hab cleared it up.) Upon our return we realized that no more EVAs would occur without a slight sim-breaking presence. While we were gone, our Crew Artist started tearing down the GreenHab, and our Commander spoke to the CNBC journalist who will be interviewing and hosting the segment in which we’ll participate.

The afternoon was quiet. We finished our final 100cameras module and watched 2010: The Year We Make Contact, which clarified many storylines for some and seemed wildly ‘80s to all. Dinner was quick, the dessert rice pudding was coconut, and our sense of the mission suddenly sprinting toward the finish line. Make it stop!

Sol Summary – May 1st

Crew 315 Sol Summary Report 01-05-2025

Sol: 11

Summary Title: Martian Sol Mates

Author’s name: Michael Andrews

Mission Status: Nominal

Sol Activity Summary:

Crew 315 has just completed their penultimate day on Mars. And for the mouse that has plagued our kitchen over the last 2 sols, it was his last sol on Mars. He was captured in our mouse trap (thanks to a bit of engineering work from me to fix the trap and a bit of bait preparation from HSO Koi) and had been involuntary signed up for today’s EVA to Candor Chasma for an empathetic release.

EVA #20 started with the Millenial Crew (read: Elena, Koi, and myself) returning a rock sample at Robert’s Rock Garden before taking our murine crew member to the Chasma. Our send-off was quite short… perhaps he had more important places to be? Fortunately, that was the only crew member we would lose on this EVA through the canyons on one of the most picturesque hikes we had performed on an EVA.

The rest of the crew was busy in the hab in the meantime. Crew Artist Gagnon was signing the back of the 1000-piece puzzle – a tradition that we weren’t aware of until it was completed. He made sure to incorporate our Phoenix crew logo and the infamous Monolith into a sketch next to the signature. Commander Laude virtually met with tomorrow’s CNBC representatives to discuss interview details.

The team reunited around noon and completed our final 100cameras module and go over logistics for tomorrow. Tomorrow’s segment is meant to address the question “Are We Ready for Mars?” Preparing for the answers to that question always sparks an enthralling conversation that has Crew Journalist Saavedra-Buckley furious jotting down notes for her article in shorthand.

The rest of our afternoon was spent watching the sequel to 2001: “2010: The Year We Made Contact”. 2 hours later, all of my Space Odyssey questions were answered, and I will leave this station more informed on historical sci-fi cinema. As the comms window opened, I went to repair our rear exterior airlock door, which has started to droop over the last week. Some quick hinge fastener tightening did the trick.

Speaking of engineering work, I wanted to end this final engineering-focused sol summary to talk about some of the conclusions we have drawn from two important pieces of our EVA equipment: our rovers and our space suits.

Regarding our rovers, we have four in our fleet: Curiosity, Spirit, Opportunity, and Perseverance. Spirit had battery issues and was out of commission for the duration of the mission, and Perseverance needed some parking brake and ignition repairs. We put a total of 22.8 hours of drive time among the Perseverance, Curiosity, and Opportunity rovers. And we preferred those vehicles in that same order, based on how efficiently their batteries’ life was consumed. Perseverance would use an average of 29% of its battery life per hour of use, Curiosity 36%, and Opportunity 50%. As I gathered this information, we used it to determine which rover was best for long range missions and also when we could use a less efficient battery to give Perseverance time to charge up.

In terms of EVA space suits, we have three flavors: two-piece suits (#1-6), one-piece suits (#7-10) and one experimental suit (#11). They all have pros and cons, and I’d like to summarize here when each should be used. The two-piece suits are the most realistic looking, provide the strongest airflow to the helmet, and are the most compact to easily ingress and egress from the rovers. However, it is the heaviest and most uncomfortable, tending to push your neck and head forward. The one-piece suit is the lightest and most comfortable, but it is the bulkiest and provides little ability to look around while driving. The experimental suit has an intermediate amount of weight and comfort and has the best helmet visibility, but it doesn’t have a battery gauge and can be uncomfortable to ride in a rover with (due to lack of neck support). In conclusion, I would recommend the two-piece suit for rover-intensive missions, the one-piece suit for walking-heavy missions, and the experimental suit for missions where you need to use a screen or closely inspect objects.

I hope this information is useful to future crews and Mission Support! We are off to get one last night of sleep in the habitat under simulation conditions. Tomorrow’s EVA #21 will be a culmination of our various projects and an opportunity to show others what we came here to do. Good night and ad astra!

Look Ahead Plan: Tomorrow we will be welcoming CNBC to the habitat for a news segment and taking them on an EVA to demonstrate our drone flights and 3D scanning capabilities. We will also begin shutting down the Science Dome and RAM and will consider ending simulation on Friday evening to get dinner in Hanksville.
