EVA #3 Report


Time:
Departed 12:10pm
Returned 1:35pm


Crew Members:
Boris Yim and Guerric de Crombrugghe


Site Location:
Outside front Hab door


Transit Mode:
Foot


Objectives:
- Make the Hab door close properly without jacking up every time.
- Requires enlarging 2 holes in a metal bar connecting the Hab door to the
wheel mount.
- Study the difference experienced in repair by EVA versus indoor.


Lessons Learned:
- Repair by EVA is much more challenging and exhausting.
- All necessary equipment has to be carried.
- Good to have main power supply near the Hab.
- More tiring to kneel down due to EVA suit, boots and weight.
- Hard to grasp and adjust equipment and components with gloves.
- Radio communication is paramount to team repair coordination, but
radio button is troublesome to reach each time.
- Hand gestures are useful.
- Helmet hindered view, bumped into structures, and vibrated by
machines.
- Too hot to do EVA at that hour.
- Smoke from drilling was blocked by the EVA suit.
- Noise from machine was lower in the suit.
- Oil for drilling contaminates gloves (and surroundings).
- Cannot make changes to repair instantly since other equipment and
materials are indoor.
- The airlock or a small separate equipment airlock can be used to
transport equipment and materials out by instant decompression. The
engineering airlock can simulate it for now, or the main airlock can
have another mode of fast decompression for those objects.
