Sol Summary – December 7th

Crew 184 Daily Summary Report  06 Dec 2017

MDRS Daily Summary Report for Sol 5

Summary Title:  Back on schedule!

Mission Status:  The past two days have been hectic due to getting in to the swing of things on Mars and the numerous failures we have encountered.  As a consequence, our schedule fell by the wayside and we were largely winging it.  Yesterday we sat down, came to a stable configuration, discussed our lessons learned from our stay so far, and prepared to jump back onto our schedule.

We are still dealing with our power system failure, but today has been a day of focus where our team is efficiently moving from task to task and completing our assigned activities.

We’ve learned today that the low battery SOC we’ve been seeing since our mission started is likely due to a misconfigured battery panel.  Mission Control is seeking help to reprogram it and return our power system to nominal.  In the meantime we will continue to minimize power usage.  Due to SOC ~ 35% it is possible we lose power tonight, our team has prepared for this eventuality and everyone is prepared to handle the cold if necessary, and all team members have light sources on hand overnight.  We have also filled reserve containers with water due the expectation that if power is lost pipes will freeze overnight.

  1. Power system is still smart enough to accept power from generator once SOC starts dropping overnight.  System Nominal!
  2. Power system swaps to generator power.  Generator Failure overnight due to the cold.  Expected loss of power overnight
  3. Power System misconfiguration prevents accepting generator power.  Expected loss of power overnight.

In the meantime, activities!

This morning we have completed Anesthesia training for all crewmembers.  On a long duration mission it is critical crews know how to treat any injuries or other problems that arise, as part of this devising methods of training for crew on a long duration mission is critical.  Our Dr. has devised a mold that simulates arteries / nerves / and veins in a leg that allows crew to practice using ultrasound equipment to identify and isolate specific body parts.  With the training complete crew will be able to complete trial runs where we see how effective this is a training device and how crew performance increases over time.

We also completed our third Matryoshka EVA to SIte #3.  We continue to collect geological samples from our target sites, though this is the first day that our crew is starting to feel the fatigue from EVA, which is hard work!.  Today’s site was exceptionally rocky which gave a very ‘martian’ feel.

Our crew is looking forward to the weekend which we have schedule as ‘light duty’ days to allow ourselves to recuperate from a very busy week!
