Narrative:

We had planned a couple of smooth EVAs to train the crew in the usage of the rovers and the suits. The plan was to have two teams of 4 people each (2 members would do 2 EVAs), however, once outside the Hab, the teams realized the Opportunity and Spirit rovers had low charge levels and the only one with full charge was Curiosity. After running in circles for some minutes, we decided to completely change the plans, we set our main priority as have all the team members trained and have their chance do to EVA.

Then we set the new plan as having three 2-people teams and use wisely the Curiosity rover. All three teams would do a short drive to Marble Ritual, explore 20 minutes at most and come back so the next team could do the same. From having planned two quite long EVAs with estimated end time at 16:30, we had three quite short (and efficient EVAs) of around 40 minutes each instead, having the last one ended at 15:30.

A quick troubleshoot from MDRS Director seemed to have solved the issue, but at the moment of writing this report, the rovers are not charging again.

We still don’t know what the problem is, which worries us a little; we’ll keep in touch with MDRS Director in order to find out what is happening.
