Sol Summary – December 10th

MDRS Daily Summary Report for Sol 9

Summary Title:  Return of the Sim!

Mission Status:

Yesterday and today has been been primarily ‘out of sim’ due to the numerous HAB failures, including our evacuation last night due to a loss of power.  We spent the morning today working to repair the generator and appear to have gotten it in working order, though further work is necessary to ensure it’s long term successful operation (see Shannon’s email for details).  The solar array system is still misconfigured so power problems may yet pop up during the rest of our sim but we will take them as we go and troubleshoot, as a real martian crew would.

This afternoon we took the rovers out to drain the batteries per Mission Control request, once returned to the HAB we re-entered SIM at roughly 5pm.

It’s been a rough first week, but we are looking forward to getting back into sim and finishing out our mission successfully.
