Hi there  Yeah its because Im not knowledgeable on the best formats for WP    I  settled for the format that preserved the most resolution  I think the thencurrent version that I modified was a pixellike format so I made the modifications with pixels and saved it in a pixellike nonvector format  And the least lossy I knew of was tif  It was important to make the corrections like center of mass location etc and improve clarity like adding the north pole and also to make things more up to date like getting rid of that asteroidlike counterweight  I made the improvements and put them in the best format I could figure out  I was also confused on how to make it as a modification in a sequence from the original and as to the best place to put it in the WP universe and so on  Anyway I was generally confused  At least I got something correct and good posted to the English WP even if the format wasnt optimal  Otherlanguage WPs still have the outofdate misleading diagrams with the asteroid etc  I would love to get those fixed with this diagram in other languages  I once saw a version on WP of the outofdate diagram that somehow had blank spaces where the words go where different languages could be filled in  The problem with that was that  I didnt know how to make it work  I only know one language English I think and  it was the old incorrect diagram  Im very satisfied with this particular diagram itself  Ive actually seen it reused in many places and presentations  One guy used it in a presentation at the Space Elevator Conference in Seattle in   I perked up when I saw it and when I told him later that it was my diagram he told me he picked it because it was the most accurate diagram he found on the internet  If you are interested in making the diagram more universal or improving it in other ways thatd be great       Not really mine of course but I felt some pride at having put the most recent work into it
