Thanks.  We did TCM 6 yesterday.  Very minor tweak.  

Turn your browers to https://www.jpl.nasa.gov   or https://www.nasa.gov  to watch the landing live.

Get in early as the servers might get crushed.  Lots more TV coverage than expected.  (Who knew!!??)

    Speaking of which, we have completed our cruise calibrations of all instruments on-board the InSight spacecraft.
    This weekend we did TCM 5 (Trajectory Correction Maneuver) to hit our landing ellipse.

    Mars Landing is on Monday, Nov 26th.

        Yup!  Long ago I learned verify the calibration of your tools, 
        BEFORE you use them to verify/validate anything else with them.

        Round 'bout way Chuck is saying "Check everything  and anything you
        canbefore you put it back on the car".  New thermostat?  Check it in a
        heated pan of water with a good thermometer.

        Every long established business, even those with golden reputations can make
        mistakes.
        
        PA Speedo is included.  
        
        We were recently working on a vintage Jaguar, the (mechanical coolant) temp
        gauge was problematic, and off it went to PA Speedo for fix/calibration.
        
        When returned and installed, we found that it was not accurate.  We
        communicated with PA Speedo are were told they tested it, fixed it,
        re-calibrated it, tested it, then shipped back to us.
        
        Shop time spent (~ $150/hour) diagnosing this old/new failure.
        
        We spent some time with the sensor in a bucket of hot water, next to both a
        digital thermometer (highly accurate) and another mechanical gauge.  The
        results did not compare to what PA Speedo stated.  We called them and
        verified what repairs they made, and how they verified the results.
        We just could not repeat their findings. (Broken again or still broken ?)
        Back it went.
        
        More shop time spent.  The car owner (a 'space' engineer) fully documented
        activities.
        After another round of calls to PA Speedo, and more shop time spent, we
        finally learned that what we were previously told by PA Speedo was um....
        not correct.  
        
        OK blunt statement here... They lied to us about their testing.  
        They didn't test it, which they now 'sort of' admit.  Rather odd reply
        actually.
        So another round of pull it out and send to them, to wait for re-delivery.
        
        Begin another round of test, adjust, validate, re-install, final test in
        car...
        
        The final result is that the gauge is much less accurate in the low, warm-up
        zone of the scale (below 50+ C) and seems to only be accurate near 80-100 C.
        
        So even famous landmark businesses can fail their customers.  
        In this case lying about test results, which caused hours of shop time, is
        just not OK, and is not acceptable, and worse that a bad repair.
        
        This seemed more than accidental miss-communication, or sloppy work, but
        intentional deceit.
        So the individual responsible should be fired.
        
        I do not know what PA Speedo did internally, but their reputation was quite
        tarnished in our view.

        Jim,
        
        Yeah it's really amazing. They are in a beautiful old building, a car
        workshop with an arched curved wooden roof with exposed beams and skylights,
        right in the middle of downtown Palo Alto. It's like walking into a time
        machine. 
        
        They have a jillion parts from every kind of gauge you can imagine. 
        
        
        
        Mike
