Purpose of EVA:  Obtain proper skills in driving the ATVs. The first pair (buddy system) will take the 2 ATVs (one person each) to the road at about 12S-51850E-425050N and then traverse to the location below on foot. Once completed, at roughly 1145, the pair will return to the HAB with the ATVs and transfer the ATVs to the second pair so that they may conduct the same mission. Each pair had a member familiar with ATVs.

Summary:  The 4 crew members during this EVA (including me) have become a bit more familiarized with the MDRS rovers (ATVs). We overestimated the time it would take to reach the destination with the ATVs since they cover ground very fast (we have a better understanding of how far/how long it would take to arrive at certain locations on the map are too). We anticipated the loss of communication with the Hab for the 2 members that would travel with the ATV and had the 2 other members help relay the communications between the ATV crew and HabCom. I would like to practice this relay method a lot more so that we can have constant communication with HabCom and all crew members.
