Frame analysis of the firing has also provided me with some rough data on the velocity of the Mousehold I probe.




The camera was filming at 14 frames per second. In between frames 2 and 3, the rocket has cleared the height of the launch tower, about 75 cm.
So, 0.75 m in 1/14 of a second means 10.5 m/s, or 630 metres a minute, or 37,800 metres an hour, or 37.8 kmph (23.4 mph). Or, to put it another way, roughly 0.09% of escape velocity.
I'm going to need about a thousand more engines! Right? It works that way, right? More seriously, I think my digital camera can be set for 30 fps. I'll try that for the next launch.
