   Hello Wilfred!   
      
   ** On Tuesday 23.02.21 - 09:47, you wrote to me:

   OK.. but considering the turmoil those capsules encounter upon     
   reentry to Earth's atmosphere (which is thicker than Mar's) I am     
   still surprised that something doesn't cause them to tip the     
   wrong way and tumbling ensues.   
      
   Entering Mar's atmosphere was less problematic.  I get that the     
   design is like a dart's and the air passing around it (drag)     
   contributes to stablize it.  It still seems amazing to me     
   especially when supersonic speed is involved and a whole lot of     
   shaking and internal heat could affect the electronics.

    WvV> That's how you know it's real! ;)   
      
   Well.. a lot of things can still be faked.   
      
   I wish we could have seen about 2 or 3 minutes more right after     
   the landing as the dust cloud settles. Then it would seem more     
   real to me.   
      
   But the choreography of events one after another and hoping that     
   there would be no malfunctions..  that's stressful.   
      
   I was reading a bit on past missions to Mars, and on one of them     
   a simple misundersting in the use of meteric vs british     
   measuring system caused the mission to fail.
