Commander's Check-In Report

Jon Clarke Reporting

Crew Physical Status: Good

Time Departed/Returned from EVA: 10:30 drill serving crew left, returned 12:30.  Field sampling crew left at 3:00 pm, returned 8:00 pm

Brief Narrative of Field Mission Results:  Drill repairs abandoned because of weather (cold, wind, blowing sand). Field sampling successful collected samples for organic extraction from Summerville and Salt Wash.  Major hitch when keys were locked in hire vehicle, requiring external assistance.  This resulted in late return.

EVA Data/Interpretations:  Repair of MARTE drill still pending.  Samples collected from bedded gypsum, venin gypusm, nodular gypsum and host shales and sandstones of Summerville and from abandoned channel fill sandstones and shales and from petrified wood in Salt Wash.

Engineering/Hab Maintenance: Repair of battery terminal of Yamaha ATV in progress.

Report Transmission Schedule: Engineering and Commander's report will be submitted later. 

Plans for Tomorrow:  Further repair of MARTE, if parts arrive.  Further repair of ATV.  Ongoing lab extraction of DNA and organics.  All these are weather permitting.  The forecast is for more wind and lower temperatures (freezing alert overnight and 12 degrees tomorrow).

Inventory:  Run out of potato flakes

Support Requested: None

Miscellaneous:  Future crews that using additional hire vehicles need to be alerted to the risk of keys being locked in vehicles by self locking systems.

Commander's Report

Jon Clarke Reporting

This has been quite a day.  Having diagnosed the MARTE problem as mechanical we dispatched the drilling team of David and Jhony to work on the drill while more specialized tools to arrive.  However the strong wind, with steady speeds of nearly 40 kph and with much stronger gusts, meant that this had to be abandoned by lunch time.  Meanwhile the biology team of Julio and Luisa worked away on the extraction of organics and DNA from samples and Carol worked on XRD analysis of mineral specimens.  Sarah collected video interviews to send to the Mars 500 crew at IBMP in Moscow, now on the "homeward leg" of their ground-breaking 520 days simulated Mars mission.  One of their crew, Diego Urbina, is an MDRS veteran. Your correspondent, the humble XO and hairy-knuckled geologist, spent the morning working on reports and field notes.

After a hot lunch, doubly welcome because of the cold weather and the near sandstorm conditions outside, a sampling team was put together to collect further samples from a former quarry near Hanksville.  The team - Carol, David, Julio and myself -set off in a hire vehicle and successfully collected a range of samples from the Summerville Formation and Salt Was Member for further analysis. 

The car keys were left in the vehicle as a safety precaution against loosing them.  Unfortunately the Chevrolet Suburban's security system, HAL-like, locked the doors after us, requiring the visit of a technician from Green River.  Future crews who hire additional vehicles should be advised to keep their keys with them, regardless of vehicles types, as this is an issue with many (though not all) modern vehicles.

So a late dinner tonight and then a review of the home movies that Sarah has been preparing to send to the Mars 500 crew.

Tomorrows plans are very weather dependent.  The forecast is for subzero temperatures overnight and only 12 degrees C during the day, and more wind.

This is crew 104 signing off.
