EVA Report – February 22nd – Mars Desert Research Station

Crew 311 EVA Report 22-02-2025
EVA # 04
Author: Célyan Ferret, HSO
Purpose of EVA: Installation of sign to deter tourist from touching LOAC
(aerosol counter), MegaArès/Field Mill (electromagnetic field sensors)
and the weather station.
Collect data from LOAC and MegaArès/Field Mill. Then collect geological
data with a drone along 1103 road by foot and then along Hab Ridge road
direction North if we have the time.
Start time: 9:00 AM
End time: 11:58 AM
Narrative: EVA Crew entered the HAB Airlock at 08:55 AM and left the
station at 09:00 AM. Somaya and Quentin took the Curiosity rover and
Célyan and Meddi took the Perseverance rover. We arrived all together at
9:18 AM at the atmospheric instruments (518250 E, 4250750 N). We
collected the data, plant the signs and take pictures. We left to go
back to the station in the rovers. We arrived at the station and started
to walk for the stratigraphy experiment at 10:30 AM. Once at sufficient
high we started the drone (3.4076453465201, -110.7928409212195 :
coordinate of the location tracker at the lower deck) and took pictures
and videos. We walked all the way up to Hab Ridge and we arrived at
11:19 AM.
Once all the pictures and videos taken for the stratigraphy and the
communication we went back by foot to the station. We entered the HAB
Airlock at 11:58 AM.
Destination: Marble Rituals, Going back to the MDRS and then Hab Ridge
Coordinates (use UTM WGS 84): 518250 E, 4250750 N (Atmospheric
Instruments) then 518100 E, 4251600 N (Stratigraphy)
Participants: Célyan Ferret (HSO and EVA Leader), Meddi Moumouni (Green
Hab Officer and having the legal papers to fly the drone), Quentin
Berlemont (Crew Astronomer), Somaya Bennani (Crew Scientist)
Road(s) and routes per MDRS Map: Cow Dung Road 0110 for the atmospheric
instruments part. Then, between Hab Ridge road and 1103 road.

About The MDRS

The Mars Desert Research Station in the Utah desert was established by the Mars Society in 2001 to better educate researchers, students and the general public about how humans can survive on the Red Planet. It is the second Mars analogue habitat after the Flashline Mars Arctic Research Station was established in 2000.

Over 200 crews of six-person teams have lived in 1-2 week field visits at MDRS to simulate life on the Martian surface. Researchers and students alike have explored the Mars-like terrain in the area surrounding the station in full “spacesuits”, maintained the station’s systems, grown plants in the GreenHab to support themselves and even recycled their waste water.

Our activities at MDRS are not only about informing the public, but also conducting real research to bring humanity that much closer to the reality of human exploration on the planet Mars.

Annual field seasons at MDRS run approx. October through May. Anybody can apply to be on a crew, and we also need volunteers to help with the project.
