EVA #7
Author: Kristine Ferrone (CDR)
Purpose of EVA: Test EVA sampling tools (radiation sensor, rake, scoop, sample bags). Identify other potential areas for tools testing along return route for EVA #8 crew to explore in the afternoon.
Start Time: 09:01 AM MT
End Time: 11:39 AM MT
Narrative: CDR (Kristine Ferrone), XO (Alli Taylor), and ENG (Ashley Kowalski) left the airlock at 09:00 AM MT. Crew proceeded in rovers (CDR and XO on Oppy and ENG on Spirit) from the Hab to Cow Dung Rd, then north on Cow Dung Rd to the Special Region. Crew exited the rovers and proceeded on foot to explore the Special Region around the quarry area. Crew collected regolith samples at three diverse locations around the Special Region, including gray, red, and green soils, paying attention to the restrictions to not disturb any fossils in the area. The regolith samples were collected using a set of EVA tools developed by XO including a rake and scoop, battery-powered sifter, and special regolith sample collection bags. Crew also noted that the Special Region would be an excellent site for a drone flight later in the mission. CDR also collected radiation dose information along the route. Comms with IVA support were limited during the EVA. Crew then returned to the rovers and proceeded back to the Hab, stopping to flag a location for the EVA #8 crew to explore for further regolith sampling in the afternoon. Rovers were parked back near the Hab and were not plugged in following power status consultation with Tier 1 support.

EVA #: 8
Author: Kristine Ferrone (CDR)
Purpose of EVA: Scout sample locations and test EVA sampling tools (radiation sensor, rake, scoop, sample bags) at and around location flagged by EVA #7 crew.
Start Time: 1:00 PM MT
End Time: 2:53 PM MT
Narrative: HSO (Barbara Braun) and Green Hab Officer (Matt Eby) exited the airlock at 1:00 PM MT and proceeded in rover (Curi) from the Hab to Cow Dung Rd, then north along Cow Dung Rd to location flagged by EVA #7 crew at the “ROUTE” marker near the intersection of Brahe Hwy (1572). Crew collected regolith samples there and in an additional location West & South of the marker that they reached on foot. HSO also collected radiation dose information along the route. Crew identified additional areas for drone flight near the second collection site. Comms with IVA support were limited during the EVA, but EVA crew demonstrated simple contingency text comms using pre-canned messages triggered by a handheld communication device, which were successful. Crew then returned to the rover and proceeded back to the Hab. Rover was parked back near the Hab and was not plugged in.
