EVA #11

Author: Ariadna Farres (HSO & Scientist)

The EVA had one goal:

Navigation exercise (aka. “Rescue Googly Mission”). Ariadna Farrés (Crew Scientist & HSO) and Cesca Cufi (Engineer) designed a treasure hunt competition for the Hypatia I crew. The crew was divided into two groups with the goal of finding 4 beacons and a final treasure in the shortest amount of time.

The first group was formed by Neus Sabate (Mission Specialist) and Laia Ribas (Green Hab Officer & Biologist) who performed the navigation exercise while Arianda Farres (HSO & Scientist) was supervising.

Start time: 9:35 AM

End time: 11:05 PM

Narrative:

This morning the first group was given the instructions for this navigation exercise, which consisted of two maps (one of the Hill at 518800E 4249100N, and the other of the entrance to Roberts Garden at 518400E 4249200N) and a pdf file with the instructions for the navigation challenge (see pdf attachment).

After performing 5 minutes of depressurization in the front airlock, the EVA team took Opportunity and Spirit rovers and headed towards Robert’s Rock Garden. Once they arrived there and parked in the designated area the time started to count. The team had to perform 3 different tasks:
Establish communications with the base from a designated area.
Head to 518800E 4249100N (which we called Hippo Hill) and find 4 beacons around the Hill
Get back to the parking area and rescue Googly (our cactus friend) that was hidden inside a small cave.

The group formed by Neus Sabate and Laia Ribas completed the three tasks in 38 min. After taking a couple of pictures to immortalize the moment the EVA crew headed back to the base. At 11:05 AM the team returned to the MDRS, before entering the Hab, they followed the 5-minutes pressurization protocol.

EVA #10

Author: Carla Conejo (Executive Officer & Biologist)

The EVA had the following goals:
Documenting the EVA for outreach purposes, by Núria Jar (Journalist).
Drone flight recording, by Carla Conejo (Executive Officer & Biologist) and the support of Mariona Badenas (Commander & Astronomer).
Collecting sand samples for the CatMart project, by Laia Ribas (GreenHab Officer).

Start time: 10:10 AM

End time: 12:50 PM

Narrative:

After performing 5 minutes of depressurization in the front airlock, the EVA team took Curiosity and Spirit rovers and headed north towards the cross with Brahe Highway 1572. The crew performing the EVA had the goals of: i) collecting sand samples searching for Martian biosignatures for Laia Ribas’ (GreenHab Officer) project; ii) documenting the latter process with a GoPro camera; and iii) recording some Martian landscape images with a DJI Mini 3 Pro drone.

The communications with the base were established with normality during the whole EVA with checks-ins every 30’ minutes. Just before arriving at Brahe Highway 1572, we parked the rovers and the EVA team climbed a hill nearby next to the road. From there, communications were established with the base to inform of our position. After that, to facilitate the communications between the EVA crew and the EVA leader, the EVA leader decided to switch between channel one and two on the radios. After taking a 5-minutes rest, the EVA team split themselves into two groups. The first group, Mariona Badenas (Commander & Astronomer) and Carla Conejo (Executive Officer & Biologist) stayed in the hill to fly the drone and take some zenith pictures of Mars; whereas the second group, Laia Ribas (GreenHab Officer) and Núria Jar (Journalist) descended the hill to access a dry water drain to search for Martian biosignatures. The two groups maintained constant visual and radio communications.

Around 12:10PM the team decided to return to the MDRS, which they reached at 12:50PM. Before entering the Hab, we followed the 5-minutes pressurization protocol.

Destination: Cow Dung Road 0110 cross with Brahe Highway 1572. Our initial plan was to reach Overlook, but we finally explored the Brahe Highway 1572 area by foot.

EVA #9

Author: Ariadna Farres (HSO & Scientist)

The EVA had the following goal:

Collect some iron-containing rock samples to evaluate its use for Martian batteries by Neus Sabate.

Start time: 2:35 PM

End time: 5:10 PM

Narrative: Before starting the EVA, we received a call from mission support advising us of the possibility of rain in the next few hours. During the whole EVA the astronauts checked the weather, which ended up being windy but with no signs of rain and the mission could be completed.

After performing 5 minutes of depressurization in the front airlock, the EVA team took Spirit rovers and headed White Rock Canyon and Barrainca Butte area to collect iron-containing rocks as suggested by Mission Support Dr. Shannon Rupert.

The EVA team drove very slowly along Cow Dung Road to decrease the discharging rate of the battery rovers. Once they reached the selected area they observed a larger amount of rocks around Barainca Butte. They spent about an hour exploring the area and collecting rocks. At 4:30PM the crew decided to head back to the base, which they reached at 5:10PM. Before entering the Hab, they followed the 5-minutes pressurization protocol.

Destination: Barainca Butte

Coordinates (use UTM WSG 84): 520000 E, 4248000 N

EVA participants: 2: Ariadna Farrés (HSO and EVA Leader) and Neus Sabate (Mission Specialist).

Road(s) and routes per MDRS Map: Drive south on Cow Dung Road 0110 and stop after the junction with Watney Road.

EVA #8

Author: Ariadna Farres (HSO & Scientist)

The EVA had two goals:

Evaluate the feasibility of navigation strategies and finalize the navigation exercise for the crew.
Drone flight training around an area with obstacles.

Start time: 10:05 AM

End time: 12:10 PM

Narrative: This morning, the Hypatia I team evaluated the weather and the condition of the road before some crew members started their EVA. For this purpose, they inspected the terrain around the base, which was dry despite the rain of yesterday night. Having identified no muddy areas, they concluded that the road conditions around the base were good and decided to proceed with the EVA. The crew also discussed the possibility of returning to the base in case of finding wet terrain along the road closer to the destination, which was not the case.

After performing 5 minutes of depressurization in the front airlock, the EVA team took Perseverance and Spirit rovers and headed towards Robert’s Rock Garden to perform two different tasks: 1) find landmarks in the area and prepare the navigation exercise for the crew; 2) maneuver the crew’s small drone in an area with obstacles.

During the pass along Kissing Camel Ridge the EVA crew lost communication with the base, once the rovers were parked around Robert’s Rock Garden we managed to re-establish communication with the base by moving around and pointing the EVA leader’s antenna north. Once communication with the base was established, the EVA team split themselves into two groups. The first group, Mariona Badenas (Commander & Astronomer) and Carla Conejo (Executive Officer & Biologist) walked to an elevated area in one of the hills in Kissing Camel Ridge to perform the drone flights. The second group Ariadna Farrés (Scientist & HSO) and Cesca Cufí (Engineer) walked around the area identifying landmarks, mapping the area and planning the navigation exercise to perform next Thursday with the whole crew. The two groups maintained constant visual and radio communications.

To facilitate the communications between the EVA crew and the EVA leader, the EVA leader decided to switch between channel one and two on the radios. Channel one was switched on every 30 min to re-establish communications with the base.

Around 11:50 AM the team decided to return to the MDRS, which they reached at 12:10PM. Before entering the Hab, we followed the 5-minutes pressurization protocol.

Destination: Roberts Rock Garden

EVA #7

Author: Neus Sabaté (Mission Specialist)

The EVA had four goals:

Check communications between the Midland radios that we brought for a larger distance between the EVA crew and the base
Collecting some iron-containing rock samples to evaluate its use for Martian batteries
Collecting some sand samples to search for microorganisms

Documenting the rock sampling for outreach purposes

Start time: 10:00 AM

End time: 12:10 PM

Narrative: After performing 5 minutes of depressurization in the front airlock, the EVA team took Curiosity and Opportunity rovers and headed towards Compass Rock. Following Mission Support’s advice, the team decided to drive at a very slow pace, which significantly decreased the discharging rate of the battery rovers. During the journey, communication with the Hub was checked every five minutes. Soon after taking Galileo Road, the transmission with the Hub became weak and on the first turn communication with the base was lost. At that point, communication with Midland radios was tested, with negative results.The team reached the final destination 10 minutes later. At Compass Rock, the team explored the area within a radius of no more than 1000 meters from the rovers. Cesca Cufí and Neus Sabaté climbed to a hill and established contact with the base. Then, they collected different samples, mainly sandstone rocks of sizes between 5-15 cm of diameter. In the meantime, Laia Ribas collected red sandstone at three different locations while Nuria Jar documented the collecting process by taking images of the locations. At 11:40AM the team decided to return to the MDRS, which they reached at 12:10PM. Before entering the Hab, we followed the 5-minutes pressurization protocol.

Destination: Compass Rock

Coordinates (use UTM WSG 84): 520000 E, 4252000 N

EVA participants: 4: Neus Sabate (Mission Specialist and EVA leader), Núria Jar (Crew Journalist), Cesca Cufi (Crew Engineer) and Laia Ribas (Green Hab Officer).

Road(s) and routes per MDRS Map: Drive north on Cow Dung Road 0110, turn east on Galileo Road 1104.

EVA #6

Author: Ariadna Farrés (HSO)

The EVA had two goals:
Drone flight around the base, with the purpose of continuing training drone maneuvers and to take some nice pictures/videos of the base for outreach purposes, by Carla Conejo (XO & Biologist) and Ariadna Farrés (Scientist & HSO).
Clean the plastic debris scattered around the base during the high-wind past days; Laia Ribas (GreenHab Officer).

Start time: 10:00 AM

End time: 11:45 AM

Narrative: After performing 5 minutes of depressurization in the front airlock, the EVA team started to walk towards Marble Ritual to find a good spot to start flying the drone to take some nice pictures/videos of the base. Three flights with the drone were performed: for the first flight the crew stayed in Marble Ritual and the drone flew towards the base and back where we were able to take some nice videos and pictures from the air. During the second flight the drone followed the crew back to the base, and the third flight was around the base.

Once the crew was back to base, the crew spent approximately 30 min walking around collecting plastic and metal debris that were scattered because of the winds of the last few days. The crew collected a total of 170g plastic debris, including bridles and other plastics, and 204g of metal debris, including wires and old nails.

Before entering the Hab, we followed the 5-minutes pressurization protocol.

Destination: Around the base and no further than Marble Ritual.

Coordinates (use UTM WSG 84): 518000 E, 4251000 N

EVA participants: 3: Ariadna Farrés (Scientist & HSO) (EVA Leader), Carla Conejo (XO & Biologist), Laia Ribas (GreenHab Officer).

Road(s) and routes per MDRS Map: Walk around the base and Cow Dung Road 0110

EVA #5

Author: Núria Jar (Crew Journalist) and Ariadna Farrés (HSO)

The EVA had four goals:
Evaluating the feasibility of navigation strategies developed by Ariadna Farrés (Scientist & HSO). Towards the end of the mission, as part of the navigation experiment, Ariadna would like to do an orientation exercise with the crew members; she needs to find locations to start planning this exercise.
Collecting some iron containing rock samples to evaluate it use for martian batteries by Neus Sabate (Mission Specialist); The project aims at demonstrating that it is possible to obtain Fe3+ ions from iron-containing rocks such as hematite, jarosite, limonite or argillite by immersing small pieces of rock in acid.
Documenting the rock sampling for outreach purposes, Núria Jar (Crew Journalist) filmed and took pictures of the crew while performing the EVA.
Creating a map of the sample collection area, Cesca Cufi (Crew Engineer) has experience in the field and will be creating a map of Roberts Rock Garden area, this has a double purpose: (1) help identify the areas that have already been sample for future expeditions; (2) help with the navigation and orientation exercise in future EVAs.

Start time: 10:14 AM

End time: 12:10 PM

Narrative: After performing 5 minutes of depressurization in the front airlock, the EVA team drove Spirit and Curiosity rovers to Roberts Rock Garden to perform the four main tasks: 1) evaluating the feasibility of navigation strategies; 2) collecting some iron containing rock; 3) documenting the rock sampling for outreach purposes; 4) and creating a map of the sample collection area.

After passing Kissing Camel Ridge the EVA crew lost communication with the base and were only able to communicate with the main Hab team with Hypatia’s own Midland radios. With the latter, communication between the EVA team and base was continuous.

When reaching our destination, Roberts Rock Garden, the rovers were parked and the team organized themselves into two groups. The first group, Neus Sabaté (Mission Specialist) and Núria Jar (Crew Journalist), explored the area looking for iron-containing rocks; they walked around the area around 4.5 miles, but never farther than 1000 meters from the rovers. Núria Jar documented all the sampling for outreach purposes. Unfortunately they did not find any iron-containing rocks. The second group Ariadna Farres (HSO) and Cesca Cufí (Crew Engineer) stayed closer to where the rovers were parked, identifying landmarks and planning the navigation exercise for the crew. The two groups maintained constant visual and radio communications.

After 1 hour exploring the area, the EVA crew walked back to the rovers, and started to drive back to the MDRS. The two rovers made a quick stop halfway before the main Hab, where they thought there might be iron-containing rocks, unfortunately this was not the case. The EVA ended an hour earlier than what was planned and will have to find other places to sample in future EVAs. Before entering the Hab, we followed the 5-minutes pressurization protocol.

Destination: Roberts Rock Garden

Crew 280 EVA Report 20-04-2023

EVA #4

Author: Laia Ribas (GreenHab Officer) and Carla Conejo (Executive Officer & Biologist)

Purpose of EVA: This EVA allowed us to perform different tasks:
We checked the communications between the Midland radios that we brought for a larger distance between the EVA crew and the base. We also continued to familiarize ourselves with the spacesuits and communication and safety protocols during EVAs and tried a new location to drive with the rovers.
We evaluated the feasibility of navigation strategies developed by Ariadna Farrés (Scientist & HSO).
We collected some soil and rock samples to search for organic molecules for Laia Ribas’ (GreenHab Officer) CatMart project. This procedure was recorded and documented as it was an outreach activity.
For the first time, our drone was flown by Carla Conejo (XO & Biologist; TRUST Certified) and Mariona Badenas (Commander & Astronomer).

Start time: 14:09 PM

End time: 16:15 PM

Narrative: After performing 5 minutes of depressurization in the front airlock, we drove Curiosity and Perseverance rovers to Cowboy Corner to perform four main tasks: 1) test our Midland radios; 2) develop navigation strategies away from the station; 3) collect samples for the CatMart project; 4) and maneuver our small drone.

After arriving at Galileo Road, we lost communication with the base and were only able to communicate with the Hab team with our own Midland radios. With the latter, the communication between the EVA and base teams worked well during the whole time.

When reaching our destination, we parked the rovers and walked west to collect soil and rock samples for the CatMart project and test the drone. Laia Ribas (Green Hab officer), Principal investigator of the CatMart project, together with Ariadna Farres (HSO) walked into a spot located in the north of the esplanade of Cowboy Road to obtain samples for the project and get some data for the navigation project lead by Ariadana Farres. The other crew members, Mariona Badenas (Commander & Astronomer) and Carla Conejo (Executive Officer & Biologist) performed maneuvers to perform drone tests. The tests were very successful, although there was some wind. We also took beautiful pictures with Hypatia and Earth flags.

After 1 hour, we walked back to the rovers, and we drove back to the MDRS while first stopping at Pooh’s Corner. In this spot, the communication with the base was recovered. We walked to the west to continue maneuvering the drone for 15 min to finalize our EVA driving safely to the station. Before entering the Hab, we followed the 5-minutes pressurization protocol.

EVA #3

Author: Mariona Badenas (Crew Commander and Astronomer) and Carla Conejo (Executive Officer & Biologist)

Purpose of EVA: The main goal of the EVA was to collect iron oxide samples for Neus Sebaté’s (Mission Specialist) research project, which consists of building Martian batteries with iron materials. During this EVA, Carla Conejo (Executive Officer & Biologist) supported Neus in the sampling process, Mariona Badenas (Commander) was in charge of the navigation, and Núria Jar (Journalist) documented the EVA for her podcast. The EVA group was accompanied by two media teams (documentary and Catalan TV press teams).

Start time: 11:20AM

End time: 12:47PM

Narrative: The EVA was planned for 11AM, but it finally started at 11:20AM. It took 30 minutes for the crew to get ready, and during this time, both the media and the documentary team recorded the preparation of the EVA. After performing 5 minutes of depressurization in the front airlock, we drove Curiosity and Spirit to Marble Ritual to gather iron-rich rock samples for Neus Sabaté (Mission Specialist). With these samples, Neus will try to build batteries with Martian-like materials.

After a smooth but windy drive to our destination, we parked the rovers and walked east of Marble Ritual, where we located many black and reddish rocks with iron oxide materials. Mariona Badenas (Commander & Astronomer) and Carla Conejo (Executive Officer & Biologist) assisted Neus with the rock sampling process, while Núria Jar (Journalist) reported the whole process with beautiful pictures (see “Pictures of the Day”).

During this time, the broadcasting team filmed the crew, although all EVA teams made the effort to disregard their presence to respect the simulation. We completed the scientific goals of the EVA at 12:15PM, after walking and sampling for 1 hour at about 400m from where we parked the rovers. After that moment, we communicated our intended route back to the rovers to the media team through a radio that we provided them, and they followed us with a drone.

We then drove back and returned to the Hab, where we followed the 5-minutes pressurization protocol. The first media team abandoned the area soon after, while the documentary team entered the base a few minutes after the EVA team returned to the base. Although we had a windy expedition, we experienced no problems during this EVA.

Destination: Originally Cowboy Corner, but Marble Ritual.

Crew 280 EVA Report 17-04-2023

EVA #1

Author: Mariona Badenas (Commander and Crew Astronomer) and Carla Conejo (Executive Officer)

Purpose of EVA: The goal of the first EVA was to perform a training for the first half of the crew, where we practiced communication between the crew members participating in this EVA and the Hab. The location for exploration was the Marble Ritual.

Start time: 3:20pm

End time: 4:54pm

Narrative: The EVA was planned for 2pm, but it started about 1h:20 min later. The reason for the delay was that the crew was waiting for three members to return from the hospital, which pushed our EVA training session to the early afternoon. The goal of the EVA was to test the rovers, practice the protocols regarding the spacesuits, and get used to the radio communication between the EVA and Hab team.

It took about 40 min for the EVA team to get ready to exit the Hab. For this EVA we used Curiosity and Perseverance rovers and we drove to Marble Ritual through Cow Dung Road 0110. After reaching our destination, we parked the rovers by the road and walked 300m around a hill to get used to moving around with the suits. During this time, all communications went very smoothly and the team took some pictures that are being attached in the journalist report. After some minutes walking around the area, we were contacted by the base to start our way back to the rovers.

Just before starting our drive back to the MDRS, Ariadna Farrés (communication leader in the base) could not establish contact with Mariona Badenas (communication leader in EVA) through channel 1; Mariona was able to hear Ariadna though. Carla Conejo switched to channel 1 –although not need for EVA performed in locations close to the MDRS– to respond to the base requirement to start our way back. In 15 min we reached the station and parked the rovers. Laia Ribas also experienced communication issues while informing about the rover’s battery level and driving hours. We then returned to the base and started with the decompression in the airlock and safe return of the astronauts to the base.

Destination: Marble Ritual
Coordinates (use UTM WGS 84): 519000 E, 4250500 N

Participants: Mariona Badenas (Commander) (EVA Leader), Carla Conejo (Executive officer & Biologist), Neus Sabaté (Engineer), Núria Jar (Journalist).

Road(s) and routes per MDRS Map: Cow Dung Road 0110.

Mode of travel: Drive on Cow Dung Road. Walk around Marble Ritual no further than 300 m from the rovers.

EVA: #2

Author: Ariadna Farrés, Crew Scientist and Health & Safety Officer

Purpose of EVA: The goal of this second EVA was to perform a training for the crew, where we practiced communication between the crew members in this EVA and the Hab. The location for exploration was the Marble Ritual.

Start time: 5:10pm

End time: 6:03pm

Narrative: The EVA started one hour later than requested as the first EVA of the day had already been delayed. The goal of the EVA was to get comfortable with the spacesuits and practice the different EVA protocols, the communication between EVA and the Hab and get familiar with the environment. This was the second time the crew was performing the PRE EVA protocol, and things went smoother than during the first EVA of the day. It took the crew 30 min to get ready to get out of the Hab.

The crew used Opportunity and Spirit for this second EVA. The first part of the EVA consisted of getting to Marble Ritual with the rovers. Once there the objective was to walk around the Marble ritual area to discover the place and get used to walking around with the spacesuits and radio communications. The crew also wanted to test the communications with the Hab using the Hypatia I personal radio set. Cesca, as the mission specialist was the one responsible to test the radio set and was caring with her two radio sets, radio number 7 from the MDRS base and the Hypatia I radio. When the crew arrived at Marble Ritual (and out of the rovers), we tested the communications with the base using the Hypatia I radios. The communications went well after adjusting the radio frequency. Once the Hypatia I radio set was tested successfully the crew decided to explore the surroundings of Marbel Ritual. This walk consisted of 15 min of the EVA where we walked around and got comfortable with the spacesuits. No communication problems seemed to exist with the Hab during the entire EVA.

Finally, the crew started the return to the Hab with the rovers. During the return to the Hab we decided to have Spirit lead the road followed by Opportunity. Upon arrival to the Hab we checked the hours and batteries usage of all rovers and started with the decompression in the airlock and safe return of the astronauts to the base.

Destination: Marble Ritual.
