I'm not sure what all these numbers mean, but KTL doesn't refer to
I wanted to get a handle on how elongated the orbit is. I found in one
location a period of between 15 and 25 hours, but that it would be brought
to under 20 hrs if it were over. The "peri-martian" altitude is about 250
mi and speed is about 10,250 mph at that point. If the period is 20 hrs I
can use Kepler's Third Law to find the average radius of orbit ( I hope).
Here is the question: Can I take twice this radius to be the sum of
"peri-martian" distance and the "ap-martian" distance? I measure these
from the center of Mars. If so I get an eccentricity of about 0.8.
