EVA # 10
Author: Elizabeth Balga
Purpose of EVA: Emergency response scenario – minor ankle injury.
Start time: 9:00 AM
End time: 11:00 AM
Narrative: XO and HSO initiated a walking EVA to the Gateway to Candor region by way of Cow Dung Rd. Upon arriving at the destination, the EVA team simulated a one-way communications failure with the habitat as well as an ankle injury. As the HABCOM for the EVA, the commander sent a rescue team consisting of the Crew Engineer and Crew Biologist to the Intersection of Cow Dung Rd and Gateway to Candor via rovers (Oppy & Curi). Two crewmembers — CDR and Communications Officer — remained at the habitat. The rescue team also brought a first aid kit, splinting materials, and a jacket for additional warmth. The HSO and rescue crew attempted to immobilize the ankle injury. All four crew members returned to the habitat via rover.

EVA # 11
Author: Elizabeth Balga for Judith Marcos & Caitlyn Hubric
Purpose of EVA:
Primary: In-situ demonstration of anchor device carrying capacity
Secondary: Biological sample collection.
Start time: 2:00 PM
End time: 4:00 PM
Narrative: CDR, ENGR, and BIO completed an EVA to Cowboy Corner. ENGR prepared for and performed an engineering demonstration of the Pleiades instrument. During sample collection with the instrument, it broke in two locations — along the handle and along the arms — which informed the weak points of the device. The Crew Engineer was able to visually confirm that the device’s operation was affected by accumulation of debris, as suspected. BIO collected seven unique samples including ice, plants, and soil from the roots of said plants. Additionally, BIO noted upon return that Percy’s left rear tail light was out.
