EVA Report #8 – February 16th

Crew 205 EVA Report 16 FEB 2019

EVA #08

Author: D. Robson, Executive Officer

Purpose of EVA: Terrain familiarization and sample collection

Start time: 0930

End time: 1200

Narrative: With the weather remaining favourable overnight and the ground being safe to walk on, it was decided that EVA 08 would go ahead as approved and planned. The team began pre-EVA preparations at 0845 hrs, and entered the airlock for depressurisation at 0923 hrs. The team of 4 headed North from the hab towards North Ridge and encountered no problems on the way to the foot of the cliff. A route, separate from 1103, was found up to the top of the ridge. The crew here decided to split into teams of 2 at around 0945, with one covering the lower areas of the cliff for sample marking, while the other completed the ascent to obtain samples from the top and take photos for outreach. Communications were maintained between both teams and the Hab, and the ascent was completed safely by 1011, by D. Masaitis and D. Robson. Two samples were taken from top of North Ridge, and the team at the bottom found a “rock garden” around the ESE of North Ridge at 0518790/4251422. This rock garden has been nicknamed “Hadland’s Garden”, after our GreenHab Officer and his dauntless quest for regolith and interesting rock samples.

Once the operation on the top of North Ridge was completed, the team of 2 were guided down the slope by the ground team of N. Hadland and G. Alotaibi, who had already identified the safest route while sample location. The teams rejoined at the bottom of North Ridge safely at 1050.

From here the full EVA team began taking samples from around the base of North Ridge and the newly identified rock garden area. Sample collecting was finished by 1130, and the team returned to MDRS by 1141 for re-pressurisation.

4) 18:15 PM 20.5° C / 35 %

Changes to crops: Some of the Arabidopsis seedlings died overnight due to the regolith drying out (see narrative). Damp paper towel germinations are starting to sprout.

Narrative: Arabidopsis seedlings were transferred into collected regolith samples yesterday and watered with Hoagland’s hydroponic nutrient supplement. However, some of the regolith samples are exhibiting interesting wettability properties and appear to be absorbing the water at an extremely high rate, causing the samples to dry out quickly. After watering with approximately 5 mL per 15 mL of regolith substrate yesterday evening, the samples dried out by this morning and several of the experiments had died. We will transfer additional seedlings into the samples later this evening. The damp paper towel germinations are starting to sprout as well so we will have additional seedlings available for experiments.

The digitized inventory of seeds as well as an inventory of the equipment available in the GreenHab and Science Dome is nearing completion and will be available to future crews prior to their rotations. More information will be available in the next Science Report.

The cucumbers that we kept in their pots are looking healthier. However, the peas are not improving and the crew will continue to keep an eye on their progress. The door was opened at 1100 hours for ambient airflow and closed at 1530 hours to prevent dramatic climate shifts.

Harvest: None.

Support/supplies needed: None.

Sol Summary – February 16th

Sol: 6Sol Summary title: Boys and Girls clubs
Author: Verónica Triviño
Mission status: Nominal

Sol activity summary: Unsure on whether the weather would permit today’s EVAs given last night’s warning of a high chance of rain and wind, crew 205 was pleasantly surprised to wake up to a sunny morning, which remained clear throughout the day, permitting both planned EVAs. The morning EVA’s crew was composed by the four men of crew 205 who went up to North Ridge and its surrounding foothills to collect samples. The four ladies used the morning to make "Kaiserschmarrn" (scrambled pancakes), write up documentation, and of course act as capcom to our bearded crew members. The girls’ EVA consisted on a drive to Kissing Camel in order to take drone footage at high altitude (and sneak in a "Charlie’s Angels" pose photo). After returning from the afternoon EVA (to a fresh pot of coffee made by the guys), we worked on writing our documentation and planning tomorrow’s EVAs. In the evening, the long-haired girls will have our once-every-3-day-super-water-efficient hair wash session which we always look forward too!

Look ahead plan: We have two EVAs planned for tomorrow, a 4-hour morning one to "The Moon" and an shorter afternoon one to Hab ridge. Other than that, tomorrow’s HSO (Dave) and myself (tomorrow’s engineer) will be working on fixing some of the spacesuits, and the journalist wants to continue filming her interviews of the crew.

Anomalies: None

Weather: sunny and clear skies

General notes and comments: Downstairs furnace was turned off due to higher ambient temperatures.

Summary of internet: Nothing to report

Summary of suits and radios: Two radios have been stuck in privacy and NOAA weather radio mode, respectively since we arrived. Following the radio’s manual did not fix them. Notes describing the issues have been clipped to the radios to assist future troubleshooting and identify them as not working. We still have plenty of radios working so it is not urgent.

Summary of Hab operations: Replaced the air filter in the heater in the lower-deck. Heater upstairs is nominal and currently used.

Summary of Green Hab operations: GreenHab smoke detector was beeping (it seems it was low in battery). Replacing its AA batteries fixed the problem.

Summary of Science Dome operations: Nothing to report

Summary of RAM operations: We observed a water leak above the workbench (we found a water puddle this morning)

Summary of any observatory issues: Nothing to report.

Summary of health and safety issues: Nothing to report

Questions, concerns and requests to Mission Support: Due to strong winds a white canvas flew towards the tunnels. We believe it belongs to Director’s compound.

4) 18:11 PM 18.7° C / 27%

Changes to crops: A pot of “Mystery Greens” was planted(see narrative below). A. Thaliana was planted in regolith-type substrates according to the mission plan.

Narrative: The door to the GreenHab was opened at 0954 hrs, due to an observed temperature of 25ºC. The Smoke/CO Detector began chirping an error code at 1018 hrs, so the GreenHab Officer notified the Health and Safety Officer and Crew Engineer, and then replaced the two ‘AA’ batteries. A test was performed on the detector, and it was remounted on its bracket. The GreenHab Officer spent the morning performing an inventory of the MDRS Seed Bank, only to find that some of the seed packets had been spilled in the can. The GreenHab Officer had a working lunch, in order to get the loose seeds re-sorted by type, and placed back into appropriate packets. Only one variety did not have a corresponding packet, and those seeds appeared to be a microgreen mix, so the GreenHab Officer discussed the matter with the Commander, and then planted the loose seeds in a pot labeled “Mystery Greens.” The crew intends to positively identify this group before departing MDRS and will be capable of reporting the group’s progress. The Comms Officer stopped by to assist with the removal of 200g (wet mass) of dead carrot biomass, as well as the harvesting of 2g of sage. The GreenHab door was closed at 1418 hrs, due to excessive wind gusts, and reopened at 1437 hrs to resume temperature regulation as winds calmed. The door was closed again by 1530 hrs as winds picked back up, but exterior thermo-regulation was no longer required. The MDRS Seed Bank Inventory was digitized by common name, scientific name, and cultivar based on information given on seed packets, and will be continuously improved prior to departure of Crew 205.

Harvest: 2g sage, 200g dead carrot biomass

Support/supplies needed: GreenHab Officer requests ziploc baggies to better organize open seed packets in the seed bank, and prevent future spilling of loose seeds from opened packets

Astronomy Report – February 15th

Crew 205 Astronomy Report 15 Feb 2019

Crew Astronomer: Ghanim Alotaibi

MDRS ROBOTIC OBSERVATORY

Robotic Telescope Requested: No

Objects Viewed: No observational session was requested for tonight. I am waiting for a clear sky for the observations submitted in 13 Feb. We wanted to submit the SY MON photometry measurement to the AAVSO However, some errors were found. The CCD setting was not correct, and there are better options to select comparison stars.

As the new set up was inserted and new comparison stars were selected, the new measured value for the SY MON star was found to be 13.918. However, the magnitude value of the check star was unreasonable and was reported to observatory director.

The crew astronomer used another method to calculate the magnitude value for the target. He measured the instrumental magnitude directly from the software and performed the calculation manually. The magnitude value was found to be 14.118. The value was also reported to observatory director.

Problems Encountered: Nothing to mention

Sol Summary #5 – February 15th

Sol: 5

Summary Title: Geology, Biology, and EVA-ology

Author’s name: Nathan Hadland

Mission Status: Nominal

Sol Activity Summary: The weather on Mars this morning was much more pleasant than on Sol 4. The sky was clear, but the muddy conditions persisted until late morning when the heat of the day started to clear the landscape of its saturation. There was no EVA today due to the unsafe ground conditions, so the sol was spent catching up on paperwork, characterizing regolith samples in the Science Dome, cleaning, and working in the GreenHab. The ISRU project reached a pivotal point today, with the Arabidopsis thaliana germinations completed and the seedlings transferred to regolith samples collected on previous EVAs using an agar media plug. Those experiments are now in the GreenHab and will stay there for the duration of the experiment. The team also made headway on our EVA optimization project. We finished designing our quantitative study to evaluate the effectiveness of EVAs and will be applying the measure to upcoming EVAs. We also worked on designing pre and post check lists for future crews to make EVAs safer, more efficient, and easier which will be available at the end of the mission. The crew’s journalist worked all day on her media and outreach project, interviewing each crewmember about their role, and recording while everyone was working. She is also designing and outreach video for kids. After the communications window and an Irish meal of shepherd’s pie tonight, the team will have our nightly meeting and leadership handover to discuss tomorrow.

Look Ahead Plan: Weather permitting tomorrow, the crew will go on EVA to continue geological sampling and testing of EVA checklists, procedures, and quantitative measures of effectiveness. Otherwise, we will continue refining the SOPs and other documentation to improve the workflow of future crews and continue to work in the laboratory. Tomorrow will also see another rotation of Commander and Executive Officer, so a new day will bring new leadership.

Journalist Report – February 15th

Crew 205 Crew Journalist Report 15-FEB-2019 Sol 5

Author: Maria Grulich

Title: New Crew member…

Today we had no EVAs scheduled due to the rainy weather conditions of last night. This means we had time to focus on our science objectives and for the crew journalist to start to interviews the crew. Today’s commander is Nathan with Veronica as XO.

Yesterday Natalia found a Martian during the EVA! As we did not know if the Martian will be friendly or not, we had to keep the little guy in isolation. Today Natalia approached him and named him Gus. Gus seems to be a very friendly Martian and happy to follow us on all our activities.

In the morning Gus followed crew astronomer Ghanim around who explained to him everything about variable stars and how to observe them with the telescope we have here at the hab. Later on, he was very interested in the Science Dome and helped Nathan analyzing his rock samples.

In the Green Hab Gus checked out how we grow plants on Mars and how Dave is planting new seeds. Gus also learned how we maintain the Hab and the space suits by following Veronica around. The space suits were so interesting that Gus wanted to try one on and Hannah gave him a radio and Gus tried on a space suit. He also talked to Daniel and he learned everything about safety and what it takes to be a Mars astronaut.

Gus is now our newest crew member and you will see him around as he wants to learn more about our habitat and Mars.

Ad Astra!
