Crew 281 Sol Summary Report 20 May 2023
Sol: 6
Summary Title:
Author’s name: Ritupriya Patil (XO) and Megan Kane (Commander)
Mission Status: Nominal
Sol Activity Summary:
EVA:
First EVA was at the Kissing Camel Ridge. The crew of 3 drove Opportunity and Curiosity rovers and reached the site at 0755 hrs. The first objective was to capture scanline measurements for the boulders Ana Pires (Crew Scientist) approved on the East ridge. KC Shasteen helped with the Equotip measurements while Ana gathered the Schmidt hammer data. After finishing 5 station long scanline. Ritupriya Patil (XO, EVA Lead) set up to deploy the drone. Detailed vertical images and videos of the scanline were captured to help confirm the weathering grade, discontinuities of the rocks. There were also 4 translational drone passes along the scanline that captured the details of the boulders under geophysical analysis. These images and videos will be used for georeferencing the area around the scanline and for further assessment of the geological region.
For the second EVA the crew of 2 erected ham radio antenna to the northwest of the Hab. A coaxial cable was retrieved from where it had been passed through the tunnel wall. The cable length dictated where the station could be installed. It took 3 attempts to find a location where the ground spike could be deployed successfully. Once deployed the ground wire and the mini were attached. This was followed by the antenna and lastly by the coaxial cable. Grounding pole could not be deployed, and the wire was affixed to a rock. The hazard cones were placed, and the crew returned to the hab.
After the ham radio station set up Rachel Jones (HSO) jumped on the radio and established contact with Dan from Govetown, Gorgia, N4MI. This ham radio testing was approved during the Karman line discussion.
In the Greenhab, Megan (Commander) watered the plants and filled the cooler.
The science dome was quiet today, cacao seeds still doing well.
In the RAM, Ritu (XO) worked on her payload carrying harness for tomorrow’s drone flight test. The objective is to test short distance payload drop off for a simulated medical emergency.
For lunch Ritu (XO) made tomato sauce based pasta with mushrooms. And dinner was stir-fried veggies in soy sauce served with rice, made by KC. After that we buried our heads in report writing and mid-mission research material.
Look Ahead Plan: Tomorrow we will do an EVA for 3 around the hab to run second test on the Pegasus scoop (rock sampling device) and do a drone payload test and drill for minimum payload weight and distance. Likely do some work around the ham radio antenna.

Sol 6, We Put Out Sticks.
Okay, not really, but it’s hard to rhyme six and an antenna.
Sol 6 was a busy day, and it started early. Ana, KC, and Ritu went on an EVA to Kissing Camel Ridge to gather more rock data from scan lines, test the geotechnical tools, and capture aerial drone footage. This was a longer EVA to start the day. Then, after a quick lunch, Megan and I performed an EVA to set up the High Frequency (HF) antenna. We set up a Chameleon HF Modular Portable Antenna System 2.0 in the portable vertical configuration. While both of these EVAs sound simple, I assure you the extreme Utah weather, in addition to the cumbersome EVA suits, makes any action outside the Hab an adventure.
With the antenna set up, the afternoon sent us all on our various tasks. Megan took on the GreenHab and checked on her chocolate plants. Ana prepared the robotic scoop Pegasus for tomorrow’s EVA. Ritu designed a dummy medical play load for her drone with KCs assistance. I, of course, was on the airways trying to make QSL contacts. Learning new equipment is always challenging, but I hope to get as many contacts as possible (pending weather/band corporation). The HF Antenna is connected via coax to a Shack-in-a-box configured to an Icom 7300, LDG tuner, and external speaker. Unfortunately, while I heard my friend Dan (N4MI) in Grovetown, GA, and Arkansas’ QSL Party, the bands didn’t support reliable conversation. I’m hoping to try again once to sunsets.
Dinner tonight focused on emptying the fridge of leftovers (one of my least favorite things). On Mars, should a crew eat group meals together? Or should individuals be required to meet specific caloric goals (i.e., you’re required to clean your plate)? I can see the pros and cons of both. Our crew enjoys the meals spent together around the table for now.
Till next time, please find me on the air! (KO4HLC/MDRS)

EVA Report – May 20th
Crew 281 EVA Report 20-05-2023
EVA # 6
Authors: Megan Kane (Commander), Ritupriya Patil (Executive Officer), Ana Pires (Crew Scientist)
Purpose of EVA:
Conduct Geotechnical Survey of the area and geomechanical assessment
Schmidt Hammer and Equotip measurements along scanlines
Geological and geotechnical assessment of the scanline using the created datasheet by the Crew Scientist
Acquire images and collect loose rock/soil samples
Drone flight to record all of the above operations and do aerial imagery
Start time: 0734 hrs
End time: 1004 hrs
Narrative:
At 0734 the three members of the EVA entered the airlock exiting at 0739. They first checked all the rovers and collected their information. Hours and State of Charge were recorded for each vehicle and it was verified that all were securely plugged in. They then unplugged Opportunity and Curiosity in preparation for heading out to Kissin Camel Ridge (Site). They left at 0745.
EVA Crew arrived at Site 0755. After parking the rovers the crew did a visual survey of the area to locate a good location for the scanline. At 0806 the crew conducted a water break. At 0809 they completed laying the scanline. Measurements commenced at approximately 0811. There were 5 stations total. See the completion times below:
Station 1 complete at 0820.
Station 2 complete at 0832
Station 3 complete at 0848
Station 4 complete at 0858
Station 5 complete at -0908
Water checks were taken between each station. Samples were collected near station 4 at 0858. When station 5 began at 0859 drone setup was started. Drone was launched at 0909 after station 5 was completed. Aerial images from the drone will be used for georeferencing the area around the scanline and be used for further overview and assessment of the geological setting. The drone landed at 0929.
At 0938 the crew headed back to the rovers. At 0943 they started back to MDRS in rovers arriving at 0955. The crew re-entered the airlock at 0959 and the hab at 1004.

EVA # 7
Authors: Megan Kane (Commander), Ritupriya Patil (Executive Officer), Rachel Jones (HSO)
Purpose of EVA:
Erect antenna to the North West of the hab’s rear airlock for Ham Radio set up
Collect footage
Note: Assistance may be needed to take a part of the antenna down in case of high winds.
Start time: 1205 hrs
End time: 1248 hrs
Narrative:
The crew exited the Hab, walked around to the approximate location for the antenna, then the coaxial cable was retrieved from where it had been passed through the tunnel wall. The cable length dictated where the station could be installed. It took 3 attempts to find a location where the ground spike could be deployed successfully. Once deployed the ground wire and mini were attached. This was followed by the antenna and lastly by the coaxial cable. Grounding pole could not be deployed and the wire was affixed to a rock. The hazard cones were placed and the crew returned to the hab.
