Operations Report – April 23rd

Crew 315 Operations Report 23-04-2025

SOL: 3

Name of person filing report: Michael Andrews

Non-nominal systems: Charger #7, Space Suit #1, #3, Perseverance Rover, Curiosity Rover

Notes on non-nominal systems:

1. (Unresolved from yesterday) It was noted that Suit #7 wasn’t charging, but further diagnosis from the Commander has isolated the issue to the #7 charger. Troubleshooting this will take place over the next day.

2. Space Suit #3’s neck ring cord broke and needs to be reinstalled. Its cord was cannibalized from Suit #1 to support an immediate EVA and will be fixed this evening. Suit #3’s oxygen cord was also cross-threaded upon install and is stuck. Some quick work with some elbow grease and adjustable pliers will fix it this evening.

3. (Unresolved from yesterday) The Perseverance Rover has two minor issues: the parking brake does not fully engage and have much effect, and the ignition block rotates fully if you turn the key too hard by accident.

4. The Curiosity Rover has a lagging battery indicator. On EVAs, its battery life percentage will drop by only a few points and register much later on the following EVA. This is believed to be fixed by watering the battery with DI water, an action for Mission Support.

General notes on rovers: I performed a power study on all three rovers based on 6 EVAs of data. Perseverance has the best battery life, and Curiosity performs equally with Opportunity. However, until Curiosity’s battery is watered, its battery level does not update real-time.

Summary of Hab operations: The crew performed another 100cameras module after breakfast, cooked bread for lunch and burritos for dinner, and performed two EVAs.

Water Use

Time of measurements: 1930
1) Per formula: 41.66 gallons
2) Smart Home Dashboard: 46.5 gallons

Water (static tank, remaining gallons): 390.71 gallons

Static tank pipe heater: Off

Static tank heater: Off

Toilet tank emptied: Yes

Summary of internet: Used to complete reports, learn languages, share team photos via Google drive, researching projects

Summary of suits and radios:

· EVA 5: Suits 8,9 and Radios 3, 4

· EVA 6: Suits 2, 7, 10 and Radios 1, 2, 5

Summary of GreenHab operations: Watered all crops, cultivated fungal project, and opened door when temperatures exceeded 94 F.

WATER USE: 11.0 gallons

Heater: Yes

Supplemental light: 0000 to 0900 and then 1900 to 2200 (light was on all night due to script needing to be rebooted)

Harvest (name, weight in grams): tomatoes (66g), chives (8g), parsley (5g)

Summary of ScienceDome operations: It was a late night last night to map the second rock sample with the 3D scanner, but it proved to be successful and very informative. This morning a third sample was scanned in about an hour… half the time of previous samples! The Crew Journalist also began her desiccated soil experiment in the ScienceDome this afternoon. The fan that cools the power converter was turned on to level 3.

Dual split (Heat or AC, On or Off): Off

Summary of RAM operations:

· Space Suit Repairs: As mentioned above, neck ring cords were swapped on suits 3 and 1 to facilitate EVA 6.

· Crew Artist’s Crazy Straw: Gagnon requested the ability to drink from his water bottle on EVAs without taking off his helmet. I fashioned a clean rubber hose from the science lab into a drinking apparatus that tapes to the suit helmet. With a little bit of adjustment, it worked well on EVA 6. Once the mission is over, it will be cleaned and returned to the dome.

· Tunnel Zip Ties: Only one zip tie was missing after yesterday’s evening gusts! A more thorough check will be performed in the AM. One zip tie was taken for install in next daylight.

· GreenHab Scale: a scale was repurposed from the ScienceDome to measure GreenHab harvests. Still troubleshooting the original scale to see if it can be fixed in the RAM.

· Other Tools Uses: Additional jars (2) were taken for rock specimens. A tool bag, carabiner, and rope tape measurer were taken for the Crew Journalist’s project, and a Rock Hammer was taken for rock specimens. All will be kept in the hab for EVA use until mission duration.

Summary of any observatory issues: None

Summary of health and safety issues: None

Questions, concerns and requests to Mission Support: Great work on fixing the main generator Mission Support! This will lower noise levels and allow us to monitor station health via Home Assistant more consistently.

Journalist Report – April 23rd

Journalist report Sol 3

We report to you having just consumed, among the five of us, 7.5 bean and beef burritos with tomatoes and herbs from the GreenHab. Spirits are fairly high in the Hab this evening, with light pouring in from the Commander’s room window and two fun EVAs accomplished. Our daily rhythms seem more customizable, and little problems seemed easy to solve via ingenuity.

Last night some crew members stayed up late working on projects while the GreenHab—erroneously—continuously glowed pink with supplemental light. In the groggy morning, we did another short 100cameras module for our HSO’s project over breakfast—we’re all now fully aware of how much our Engineer likes photos of cats. We then discussed lowering our paper towel consumption and the water we use to wash dishes, and our HSO and Journalist got ready for their EVA out to Somerville Overlook. While some human error on the Journalist’s part led to minor radio issues, the two made it over the bumpy road like Martian monster truckers. The view poured out in front of them when they arrived. HSO took some drone footage, and looking skyward toward the device returning, while wearing a one-piece suit, proved so awkward that she fell over a bush. Immediately after the drone landed back at HSO’s feet, five Martian pronghorn sprinted right past the EVA crew. The rest of the outing included some soil sampling and more drone practice on Cow Dung Road.

The second EVA took our Commander, Artist, and Engineer out to the same location, where our Engineer made some progress on his Starlink project and collected more rocks for 3D scanning. Our Commander made visual contact with one of his favorite geological formations on Mars—the Monolith—and took coordinates so he could get closer with either drone or foot on another EVA during our mission. Wind and dust devils shooed them back to the Hab.

Our Journalist prepared fresh tortillas for those burritos (which used leftover chili made by our Artist). She entered her first flow state on Mars while making them. She is realizing that she needs to do a second mission entirely devoted to Martian culinary arts.

GreenHab Report – April 23rd

Crew 315 GreenHab Report 23-04-2025

GreenHab Officer: Elena Saavedra Buckley

Environmental control (fan & heater): On

Average temperatures (last 24h): ~87-90

Maximum temperature (last 24h): 101.3 F

Minimum temperature (last 24h): 72.7

Hours of supplemental light: Unknown (see below)

Daily water usage for crops: 11 gal

Daily water usage for research and/or other purposes: Some mists for mushroom kit

Water in Blue Tank (200 gallon capacity): 158.8 gallons

Time(s) of watering for crops: 8:30 am / 6:45 pm

Changes to crops: None

Narrative: The supplemental light system seemed to be on all night, likely due to a snag with the Smart Home system and power; we noticed it as we went to bed, and I wasn’t sure whether that was normal. It was on when I went in the morning, so Mission Support rebooted the system and they turned off. It was again very hot in the afternoon, 102 degrees, so I left the door open until it cooled down. We also harvested some produce for burritos.

Harvest: 66g tomatoes / 8g chives / 5g parsley

Support/supplies needed: None

EVA Report – April 23rd

Crew 315 EVA 6 Report Date: 23 APRIL 2025

Sol: 3

Summary title: EVA 6 Overview

Author: Tim Gagnon

Purpose of EVA: Starlink Test and collect rock samples for 3D scan experiment.

Start time: 1330 hours

End time: 1625 hours

Narrative:

The Commander, Engineer, and Artist departed the Hab at 1330 hours on an EVA to Somerville Overlook. Utilizing Rovers Perseverance and Curiosity, the drive took about 45 minutes. When we arrived and parked, we set off on foot to the edge. The artist concerned about making the return trip to the rover stopped after 30 yards and turned around. He then did a photo survey of the landscape and photographed the Commander and Engineer proceeded to the edge so the engineer could deploy his portable Starlink system. It acquired a signal within three minutes of deployment. The Engineer then surveyed the area for interesting looking rocks for his 3D experiment. At about 1540, we began our drive back to the Hab. On Galileo Rd, the commander noticed the structure he calls “the Monolith” to our north so he stopped and with the Engineer tried to determine coordinates of its location. Once we got back to driving, the Commander pointed to a “dust devil” and the artist took photos as it crossed the road.

We arrived back at the Hab at 1625 hours.

Destination: Somerville Overlook

Coordinates: 4253000N, 522150W

Participants: CDR: David Laude, ENG: Michael Andrews, Artist: Tim Gagnon

Route: Moonwalk Road, Cow Dung Rd, Galileo Rd.

Mode of travel: Rovers Perseverance and Curiosity.

EVA Report – April 25th

Crew 315 EVA Report 25-04-2025

EVA # 9

Author: Elena Saavedra Buckley

Purpose of EVA: To better view the Monolith and (for the Journalist’s purposes) to get one-on-one time with Commander

Start time: 0940

End time: 1252

Narrative: The Commander and Journalist took Perseverance up toward Green Mars View, where they walked around the rim of the canyon, took in the view, and talked. They trekked slightly north to get a better view of the Commander’s area of interest, but compass readings indicated that something the Journalist saw a previous day, with the Engineer, probably wasn’t it. They then went slightly west, dodging cacti, to get a better view and stopped a few times along the way. We considered going to Lith Canyon, but there wasn’t enough time. On the way back down Cow Dung, we stopped briefly for the Journalist to collect a soil sample.

Destination: Green Mars View

Coordinates: Green Mars View, 4257000N, 520500W

Participants: David Laude (Commander) and Elena Saavedra Buckley (Journalist)

Road(s) and routes per MDRS Map: Went from Moonwalk to Cow Dung Road, then took a left and headed toward Green Mars View, where we parked the rover. Walked approximately 10 minutes north to get a better view of the Monolith.

Mode of travel: Perseverance and foot.

Journalist Report – April 25th

Journalist report sol 5

After a few days on Mars, people get comfortable, start to stare into the middle distance, and have interesting discussions over homemade Hab pizza. Today was productive and exploratory for the crew.

Wakeups are a bit more automatic now—this Crew Journalist rose and watched her phone clock turn from 6:59 to 7:00—and this morning flowed fairly seamlessly into our crew meeting, which had to do with lowering our water consumption along with planning EVAs and a few goal happenings for next week. Our Commander and Journalist left on the first EVA toward Green Mars View (which the Journalist realized she and the Engineer had not quite reached last time), where they took in the view at the canyon ridge for a meditative stretch before walking toward a nearby elevated area to look for the Monolith. A few things poked out of the distant rocks, but nothing definitive; on the drive back, the two stared at a column-like rock formation many miles away, waiting for the shifting light to reveal its identity, before deciding they had probably failed. Fortunately, this only makes things more interesting.

The wind picked up in the afternoon, so our Engineer and HSO went on a short, one-hour EVA to release the rocks the Engineer had 3D scan back into the wild, and to test the drone in windy conditions.

Of course, the food: from-scratch corn muffins with cheddar cheese and chives on top, and a couple pizzas using a variety of pantry and GreenHab ingredients (photos attached). The Journalist enjoyed listening to music from the Commander’s digitized ’60s tape collection while kneading the dough. Now that suiting up, report writing, and scaling the Hab’s steep stairs are familiar, we can spend our cognitive energy on other pursuits—our pre-report evening has ended with a varied discussion on bigger questions around Martian exploration.

EVA Report – April 25th

Crew 315 EVA Report 25-04-2025

EVA # 10

Author: Michael Andrews

Purpose of EVA: We planned to first visit the site from EVA #3 in order to return the 5 rock samples that were collected to as close to their original location as possible. Then we intend to proceed to the true location of Robert’s Rock Garden and collect 1-2 more specimens for 3D scanning. Simultaneously, HSO Koi was planning on performing some drone testing in these high winds conditions to prepare for any contingencies in future EVAs with gusts of winds.

Start time: 1510

End time: 1610

Narrative: The HSO and Engineer departed the station slightly after 1400, entering a significantly windier environment than normal. We plugged in Perseverance before departing via Curiosity. The trip to EVA Site #3 only took about 5 minutes, and took another 10 minutes to return rock samples as close to their original locations as possible.

The EVA Crew then traveled approximately 5 minutes south further along Cow Dung Road until we believed we were at Robert’s Rock Garden. We radio’ed in with CapComm to have them check our EVA Link location, and CapComm rep Gagnon confirmed we had indeed arrived at the Rock Garden.

Andrews walked around the area looking for rock samples to take back to the ScienceDome for 3D scanning, while Koi tested drone operations in windy conditions. Andrews was able to recover 1 sample, and Koi’s drone did throw some wind alerts and required some compensation when flying.

Once all objectives were complete, the team returned to the station in about 10 minutes and began repressurization.

Destination: Robert’s Rock Garden and rock sample collection point from EVA #3

Coordinates (use UTM WGS 84): Easting: 518250, Northing: 4249000 (Robert’s Rock Garden) and Easting: 518250, Northing: 42450000 (EVA #3 site)

Participants: Michael Andrews (Crew Engineer and EVA Lead) and Urban Koi (Health and Safety Officer)

Road(s) and routes per MDRS Map: Used one rover to travel along Cow Dung Road until reaching Robert’s Rock Garden and parked on the road berm. The EVA team then traveled on foot, traveling no further than one mile from the rover.

Mode of travel: Used Curiosity rover to travel to the coordinates above. The EVA team then traveled on foot, traveling no further than one mile from the rover.

Operations Report – April 25th

Crew 315 Operations Report 25-04-2025

SOL: 5

Name of person filing report: Michael Andrews

Non-nominal systems: Suit Charger #7, Catalytic Heater, ScienceDome Radio Charger

Notes on non-nominal systems:

· (Unresolved from yesterday) It was noted that Suit #7 wasn’t charging, but further diagnosis from the Commander has isolated the issue to the #7 charger. I was able to observe that all chargers appear to work, so more formal diagnoses are required.

· (Unresolved from yesterday) The catalytic heater near the exercise bike in the habitat does not work. It’s an engineering project to see if this can get properly started during this mission.

· The ScienceDome radio chargers do not work. There seems to be a loose component internally, because the radios will flicker on and off between charging. Furthermore, docking the ScienceDome radios in the GreenHab hold a charge nominally. Radios were swapped between the two structures, and I will disassemble the charger tomorrow.
