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.

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.
