Crew 274 Journalist Report 1-30-2023

Sol: 1

Author: Tony DiBernardo, Crew Journalist

Title: The Inner Light

After a successful arrival and ingress into MDRS yesterday, Crew 274 woke up in simulation this morning at 7:30am to the song “Don’t Worry, Be Happy” and a recorded message from Dr. Kristen Miller, inspiring the team with advice and encouragement to embrace the experience. The “Wake Up Song” tradition, dating back to the Gemini program, will live on through the crew as each day they’ll hear a song and message sent to them from a family member or supporter of the program. Then, every morning, each crew member will complete an Emotional Recognition Test and a Psychological Survey that consists of 234 questions to track changes in each crew member over the course of the mission.

The crew consists of 8 members, all with their own experiments:

Commander Sarah “Ceres” Guthrie
Experiment: Evaluating Contingency EVAs and Rescue Techniques for Planetary Surface Missions

Crew Engineer Lex “Kepler” Lojek.
Experiment: Focused breathing and its effects on physiological indicators of stress and performance.

Crew Astronomer Salina “Nova” Pena
Experiment: Generating Multi-bandpass Lightcurve Data on HADS Variable Star v0799 AUR

Crew Astronomer Noah “Phoenix” Loy
Experiment: Analyze Solar Flare, CME, and Daily Space Weather Data

Health & Safety Officer Nick “X-Man” Pender
Experiment: Supply Cache Use for Extension of Human Exploration on Mars

GreenHab Officer Tyler “Houston” Hines
Experiment: Observing Growth Rates Of Space-Exposed Seeds In Martian Simulated Regolith Samples

Hab Specialist, Secondary Engineer Bill “Titan” O’Hara
Experiment: Habitat Design Case Study

Crew Journalist Tony “Iron Man” DiBernardo
Experiment: In-Hab and Extravehicular Media & Outreach

EVA Activity

On the first day of the mission, two training EVAs are required of the crew by MDRS Mission Support to walk through all EVA practices and procedures. Prior to the first EVA, Tony “Ironman” DiBernardo had an issue with the air supply connections being cross-threaded on his EVA suit. We moved to a different suit for the EVA and afterwards, Lex “Kepler” Lojek and Bill “Titan” O’Hara were able to troubleshoot and repair the suit. Both EVA crews used the rovers to drive out to Marble Ritual, a landmark nearby the habitat. The assignment was to perform an hour-long EVA and return safely. The crew members became familiar with the rovers, explored, collected rocks and petrified wood, and acclimated to the new simulated martian landscape.


Tyler “Houston” Hines, Greenhab Officer, began his two experiments in the science dome. His experiments involve growing seeds in a mixture of simulated Mars regolith, organic material and water infused with potassium, nitrogen, phosphorus. The seeds being tested are standard microgreens and seeds from NASA SEEDS experiment, which flew seeds to space aboard the Long Duration Exposure Facility (LDEF), launching in 1984 aboard Space Shuttle Challenger and returned in 1990 by Space Shuttle Columbia. Tyler was advised by HSO Nick “X-Man” Pender on the memory functionality of the Thermo-hygrometer and will continue to water and monitor growth throughout the remainder of the mission.


Crew astronomers Noah “Phoenix” Loy and Salina “Nova” Pena canceled all operations due to cloudy weather and non-optimal viewing conditions, but were able to take required pictures of the Musk Observatory, including the astronomy laptop boxes, the first aid kit and the solar telescope. They plan to continue heliophysics and High Amplitude Delta Scuty (HADS) observations tomorrow, weather permitting.

Hab Design

Bill “Titan” O’Hara started a draft of a habitat design case study report. This report will explore and analyze the effectiveness of the design of the MDRS habitat to inform the design of future habitats. Bill also worked with Salina to take a complete inventory on all food in the hab, identifying and planning our use of food for the remainder of the mission.


Lex “Kepler” Lojek took measurements of the water level to find that the crew used more water than was originally allocated per day to have the water supply last for the duration of the mission. Prior to entering simulation, he made a starting measurement of 491 gallons, which gives the crew approximately 35 gallons per day for drinking, showering, dishes, bathroom use, and all other water usage excluding watering plants in the GreenHab. Before 5pm on Day 1, Lex measured a total water tank volume of 445 gallons, coming out to 46 gallons used by the crew so far. Thoughts were thrown around by the crew on water conservation efforts, such as using cooking and dishwashing water for other uses, but the crew agreed to continue for 2 more days without extreme water rationing to create a more accurate estimate of projected daily use.

Health & Safety

Health & Safety Officer, Nick “X-Man” Pender, will be conducting an experiment to implement supply caches along EVA routes to set a baseline for safe travel distances by foot. Identifying these limits will ensure that no terrestrial astronaut will be without supplies should an emergency occur while on EVA. Today, Nick tested the operability of an in-suit hydration system and confirmed that the proposed hydration hose and GU Energy gel pack can indeed fit into EVA helmet. He plotted the route for tomorrow’s EVAs which will establish a 30-minute hiking distance baseline and he prepared the GPS equipment for crew use on all future EVAs. During dinner, Nick alerted Mission Control of a broken oven knob that wouldn’t allow us to turn the stove off on one burner. Ultimately, we pulled of the knob and forced the knob to the off position with pliers.

We ended the day cooking spaghetti with dehydrated bean-bolognese pasta and parmesan while watching Star Trek TNG S5E25: The Inner Light. Tomorrow, we look forward to clear skies and safe EVAs. Ad Martes!

Crew 272 Journalist Report 1-13-2023

Author: Kenny Pritchard, Crew Journalist

Title: Lakshya (“Aim”)

For our final crew breakfast on Mars, despite rumors of lasagna, Adriana whipped up some biscuits and rehydrated butter. Our EVA this morning was planned for an early 9:00 a.m. departure, so we had little time to dilly dally – we ran an oxymoronically compacted stretching session, and four of us suited up for the EVA with biscuits still in our mouths.

The mission today was a real search and rescue to find and retrieve the Boiler Transmission Station (BTS) which had been deployed to a ledge near the Hab (we deemed it Boiler Ledge) on a previous EVA. After a few powerful dust and wind storms, the crew was concerned that it may have been blown far away from its last known location and lost to the sands of Mars. Mason, Arly, Megan, and I took the rovers to a good stopping point, walked up a familiar hill, and began scouting toward the expected location with the drone. This cycle of walking and scouting repeated a few times until we got close enough to where the drone camera could almost make out our target and we could walk over to Boiler Ledge. Lo and behold, the BTS sat serenely waiting our arrival, if a little waterlogged, and missing its original housing box. We collected the treasured transmitter and took some good drone videos and pictures hoisting our Purdue “Boiler Up” flag near the edge of Boiler Ledge. Having made excellent time to the Ledge and finding the objective easily, we made it back to the Hab before noon, where the rest of the crew sat working on the final tasks of our rotation: finishing up research, cleaning up, packing, and a writing a whole slew of end-of-mission reports.

With our time at MDRS coming to an end, it’s a good time to reflect on the progress we made. Although our crew had been meeting and planning for months leading up to our rotation, we had only just seen the tip of the iceberg of each other’s personalities and life stories (and flaws) (just kidding). Living together in an enclosed space on an inhospitable planet for two weeks was a quick fix! We’ve voiced our pet peeves, become adept with our equipment, endured exhausting EVAs, overcome unexpected challenges, been sim-resurrected from several sim-deaths, formed alliances and fought wars over board games, and we can proudly say that every crew member has achieved at least the minimum objectives of their research. The difference between our first steps and what we’re capable of accomplishing now is night and sol.

One common theme of each sol has been abundant references to the 2004 Bollywood movie Lakshya, shared with us by our fearless commander Kshitij. In this film, the main character asks himself “Main Aisa Kyun Hoon” – “Why am I like this?” and struggles to find his aim in life. I’d compare our first meetings and our final sols here with the beginning and end of the film, our crew taking a dynamic arc from inexperience and lack of direction to a resolute sense of purpose and efficiency, thanks largely to Kshitij’s wisdom and leadership (and humor). It’s been a good run here on Mars, but today we end our simulation to prepare for the long ride back to Earth! On behalf of the entire crew, thank you sincerely to all the loved ones who followed our journey and kept in touch along the way. Your support means… the world!

Signing off from Mars,

Adriana “Rocky” Brown, Arly “Maple” Black, Kenny “Hemingway” Pritchard, Dr. Kshitij “Chai” Mall, Madelyn “Sprout” Whitaker, Mason “Scout” Kuhn, and Megan “Xerox” Rush
