Crew 310 EVA Report 05-02-2025
EVA # 05
Author: Mònica Roca i Aparici
Purpose of EVA: Installing and fixing the Corner Reflector plates on the already installed structure. Install the GNSS antenna centred within the reflector and connected to the coaxial cable set on EVA # 02.
Start time: 08:15
End time: 12:00
Narrative:
We exited the base from the RAM and walked slowly uphill to the concrete patch, with the Corner Reflector plates. It was very windy so we began checking the structure, bolts and screws that we installed yesterday. We fixed one extra bolt and proceeded to prepare the tensors that will be attached to the plates ensuring its robustness.
Then we proceed assembling the plates upside down to finally mount the reflector on top of the structure mounted yesterday.
Later we fixed the tension pegs to the ground.
While we were working on the tensor pegs, Helena went to take pictures of the solar panel experiment located east of the observatory.
Finally we mounted the GNSS antenna, attached to a stick, on the corner reflector vertex, to measure its position. And we connected it to the coaxial cable that we set on EVA # 02.
Then the four of us entered the RAM. Overall, the EVA was a success and the reflector will likely be finished in the next EVA.
