Patiently waiting for updates... OK, not strictly true.

I haven't tested it in a while, but I thought premium repairs would persist through re-docking to the ship, even with the automated repair there. Did this change, or am I remembering wrong?
And... ouch! Hitting the wrong synth definitely hurts.
I hit the ground with a big fireball
Commiserations! But to quote the philosopher Neil Young, It's better to burn out than to fade away!
Perhaps sir would like something a little less large? I admire the ambition, but somewhere you don't feel the pressure to cover a lot of ground in a hurry might work better?
Good luck anyway!
I plan on lifting off with this being my starting point for a galactic circumnavigaion.

In his experiment, Eratosthenes made the assumption that the Earth was a sphere, and that the suns rays are parallel as they strike the Earth. We now know today that these assumptions are not perfectly correct since the Earth bulges slightly at the equator, and there is a slight angular difference in the suns rays as they strike the Earth, most pronounced at the poles, but only measurable with modern equipment. For the purposes of this experiment, those assumptions have minimal impact on the final result.
As the chief librarian of the Great Library of Alexandria, he was well educated and well informed. One of the pieces of information he learned was that on a specific day in June in the city of Swenet there was a deep well that the sunlight reached the bottom, meaning that at noon at that location, the sun must be directly over head at 90°. He also knew that on the same day in Alexandria, there were shadows cast at noon. He measured the noontime angle of the shadow cast by an obelisk. He knew the distance between the two locations. With this information, he was able to use a simple proportion formula d/P = a/360 where d is the distance between two locations, P is the perimeter, or circumference, and a is the difference in shadow angle. Solving for P, we get 360d/a.
While Eratosthenes chose to take his measurements on the summer solstice because of ease of measurement in knowing that one of the locations had an angle of 0°, the same can be done by measuring the angles and subtracting to find the difference.
Awesome! Again.I broke out the Haversine formula, measured angles, and once again, employed Eratosthenes' great experiment.
From my thread Meridian - A planetary circumnavigation:
I took my measurements in one of the larger craters, on one of the only sunny days so far.
In this attempt, it was a bit different with the shadows because I am in my Anaconda, Buckeye Spirit, and the shadows are very different. Using the haversine formula, I calculated the distance between North Site and South Site to be 113.8km.
Here are the results...
Even more accurate than the last time. I was able to calculate the circumference to within less than 35 km on a body over 12,684 km around.
Well, if you are still anywhere in the vicinity, I'm going to be on the moon for a while, so stop on by!WOW! I just flew through that neighbor hood, might have miss ya you by a few LY's lol. Good job finishing what you started.
I think I am beyond that now so will have to check, otherwise if I'm not that far I might double back and drop in for a beer.Well, if you are still anywhere in the vicinity, I'm going to be on the moon for a while, so stop on by!
