EVA 4 Report

Crew 97, XO & Human Factors Researcher Reporting

Time: 14:27 / 16:45

Crew Members: XO & Human Factors Researcher

Site Location: East of Hab, Phobos Peak

Transit Mode: Walking

Objectives: To reach the top of Phobos Peak to collect the panorama that could not be taken during EVA 3.

Results: Two samples taken, one on the way to Phobos Peak and one on top of Phobos Peak. Two locations found for collections for Commander's experiment. One location found for collection for Engineers's experiment.

Lessons Learned: Visibility decreases significantly over time. Condensation collects on the bowl of the helmet as well as sunglasses worn. Ensuring defog chemical is applied prior to EVA should help with visibility issues.
