EVA Report – February 18th

Crew 275 EVA 5 Report 18Feb2023
EVA #5

Author: Quentin Royer (Crew Engineer)
Purpose of EVA: Deployment of the meteorological mast and test of Mega-Ares

Start time: 10:03
End time: 12:48

After placing all the equipment needed in the Engineer Airlock, the EVA Crew started their depressurization at 10:03. They departed to the location where the MegaAres antenna was set up during EVA #3, between the MDRS and Marble Ritual, using the Opportunity and Perseverance rovers. The EVA Crew arrived on-site at 10:28.

The EVA Crew unloaded the equipment from the rovers and started to build the weather station and to set up the 3 instruments to be placed on the mast. First, the field mill was set up, but only partially because there was a failure in the battery wire, which will have to be repaired in the RAM. Then, the PurpleAir instrument was set up successfully. Finally, the anemometer was installed, and is fully operating.

The weather station and its instruments were fully deployed at 11:34.

Then, the EVA Crew started performing tests on the MegaAres instrument. Almost all of them were successful, but one of them was a failure, and on repairs were undertaken on-site. They were successful, and the MegaAres instrument started to collect data.

The Crew departed the location at 12:40, returned to the MDRS and unloaded their tools into the Engineer Airlock. The EVA Crew entered the main Airlock at 12:48.

One objective was only partially achieved (Field Mill deployment) and will be finished during another EVA later in the mission.
