Thanks, i think NASA can see how the rover's capsule hits the air when landing.BTW the Oscilloscope that you saying is very creative the adjustable things uses e.pos(0) or e.pos(1) according to my logic .
Very good .The script that you wrote is better than me.
BTW my script is very easy for thyme begginer.
P.S
Please check your desc , you forgot to 'space' between similar and to .
