Crew 315 EVA Report 28-04-2025
EVA # 14
Author: Michael Andrews
Purpose of EVA: The crew was to explore the area surrounding the station and accomplish the following objectives:
· Scanned a rock sample with a constructed shroud out on EVA.
· Crew Artist took photos for more artwork and sketches to be composed post-mission.
· Repaired some tunnel tarp rips from the exterior surface.
Start time: 1010
End time: 1158
Narrative: Crew Artist Gagnon and Engineer Andrews departed the airlock at 1010 and brought their supplies out onto the station porch. Gagnon began looking for suitable rock samples while Andrews began to set up the shroud.
The sampling exercise was mostly successful. The first two scans ran nominally, and the third time took some time to upload and rebuild. During this time, Andrews unplugged the camera from the laptop prematurely, which caused the third scan to build incorrectly. This third scan was meant to capture the bottom surface of the rock, so that surface was not properly captured. The entire exercise took about 40 minutes.
After packing up the 3D scanning supplies, Gagnon and Andrews pivoted to tunnel exterior side repairs. Gagnon mainly held all supplies or braced the ladder while Andrews applied zip ties or duct tape patches. At times where the tunnel tarp was tight, they radio’ed CapComm to press on the tarp to relieve the tension from the inside of the tunnel. The science dome tunnel had the largest gaps, and Gagnon expertly created a weave of duct tape patches to seal this tightly.
The team worked right up to the end of the EVA window on repairs, entering the airlock at 1158.
