Crew 281 EVA Report 19-05-2023
EVA # 6
Authors: Megan Kane (Commander), Ritupriya Patil (Executive Officer), Ana Pires (Crew Scientist)
Purpose of EVA:
Erect antenna to the North West of the hab’s rear airlock for Ham Radio set up (not achieved)
Test rock sampling device (Pegasus scoop) and collect samples.
External inspection of the hab, since there were some loose cables/bungee cords banging the hab walls during yesterday’s storms.
Video record the operations
Start time: 0838 hrs
End time: 0954 hrs
Narrative:
Shortly before the EVA it was determined we needed additional time to prepare and test the Ham Radio setup. It was decided that Rachel would focus on this and not go on EVA therefore the first purpose listed was not achieved.
At 0838 the two members of the EVA left. The first objective was to inspect all rovers and collect their information. Hours and State of Charge were recorded for each vehicle and it was verified that all were securely plugged in.
After this the EVA conducted a visual inspection of the hab to ensure there were no safety concerns after yesterday’s storm. Once that objective was complete, the EVA members went to the chosen test site for the Pegasus scoop test. While assembling the scoop for the test, the battery connection was damaged and the test was aborted. Ana (Crew Scientist) repaired it in the hab, post EVA. After documenting the attempted test and conducting a quick drone survey of the area the crew packed up the drone into its case. The drone was carried back to the hab and stored in Spirit’s cargo bay to be retrieved prior to return.
After a short water break they went to collect samples from the area surrounding the hab as described in purpose 2 of the EVA. They also took photographs of the area.
At 0928 the drone was deployed to take visual imagery of the habitat and surrounding area for geolocation mapping. Drone deployed to 80 m initially ascending to 97 m at 0933. The drone landed at 0939 with 42% battery remaining.
After a second watercheck the EVA crew made their way back to Spirit to collect the Pegasus Scoop. Enroute they discovered and retrieved some man made debris and retrieved it for disposal in the hab. They returned to the Hab entering the airlock at 0949.
