EVA #: 3

Purpose of EVA: Geology
Start time: 0900
End time: 1025

Narrative: The EVA started with the purpose of proceeding to cowboy corner via rover and walking to Tharsis Montes via foot to collect geology samples. The crew started out well and in high spirits and reached about halfway before completely losing comms with the habcom. We returned to a point where we could hear them but continued to have a loss of communication due to significant noise. Upon miscommunication, we remained on standby near Galileo road before being asked to return. The noise in our communications led to the understanding that the EVA crew could not communicate with each other, although we were able to hear each other on Channel 2. We returned in high spirits after having enjoyed the weather and getting practice in operating our EVA suits despite not achieving our original mission. The team had a significant learning lesson and developed an improved communications plan for our next EVA, and affirmed over the course of the day that the repeater was interfered with in our canyon, causing the noise or loss of contact with the long range communication (channel 1). We returned on time and were in high spirits despite the situation.

EVA #: 7

Purpose of EVA: Geology
Start time: 0900
End time: 1205

Narrative: The EVA crew left the main hab on the perseverance rover in good spirits and under amazing weather. The crew proceeded to the Gateway to Lith dinosaur quarry and followed the pathway without an interruption. Once in the dinosaur quarry, the crew was able to explore the beautiful terrain, found Martian water, and was able to get some media documentation of our exploration. Additionally, we saw several cool rocks that formed in the area and were able to collect a few geology samples. Once done with our sampling, we left the quarry and proceeded back to the MDRS base with our Plan B, Cowboy Corner, as a pit stop. There, we also collected samples and documented our experience while enjoying the beautiful sun. We also encountered an alien on foot and proceeded to stay away from them to keep ourselves safe. Finally, we made it back to the MDRS base after an amazing, safe, and productive EVA.

Crew 319 enjoyed a more restful Sunday evening and caught up on some sleep before heading out on two, three-hour EVAs today, the longest we have achieved so far. EVA Crew 1 with Commander Rym Chaid and Crew Scientist Shriya Musuku took Perseverance Rover to the dinosaur quarry at the Gateway to Lith to explore the terrain before collecting mineral samples at Cowboy Corner, including some surprise pieces of what appears to be quartz. EVA Crew 2 with Crew Engineer Ricardo J. Gonzalez and Crew Journalist Mackenzie Calle took Opportunity Rover for its first EVA of our mission and headed to Somerville Overlook and were astounded at the views of the canyons and plateaus that we could see for miles. They also collected many geological samples, especially those that had crystalline and botryoidal structures. We noticed a strong sprinkling of red rock amongst the soft clay. The marbling in the canyon plateaus was also very strong.

The two EVAs were very productive and encouraging for both crews.
