Mars finished
Dear all
So moving up the model it starts to "close in" (of course). I found that for the next ring it would not be good to complete the ring and then add the two layers of tape. This is because of the size to is just too far to lean down in and back under yourself. So what I found best was to add the tape as each section was glued into place. These photos show this process And here is the ring finished And then the next ring And then the next ring as well as what it is like inside This just leaves the south pole to add. However I made this into two parts, where the inner part is about 10cm (4 in) in diameter I reinforced the final ring with ring of 1mm thick card and 15 mm wide. The final part of the south pole was mounted onto a 1mm thick card disc of 13 cm diameter. This means the South Pole "plug" can be slightly flexed inside the final ring. So here is the final ring added to the globe So now the beach ball is inserted and then inflated. I used this ball which I got from amazon https://www.amazon.co.uk/Intex-Giant.../dp/B00O80ZA26 Note it says it inflates to 42 inch diameter. That is not the case. But it goes to a little over 75 cm diameter which was fine for what I wanted. So once inflated to just gently push on the side of the globe I inserted the south pole. And here is the finished globe The detail of NASA's image is excellent, naturally (photos I have taken do not show that). I would say it can get a bit laborious doing all the tape layers, but, if you like globes at all, I think you would enjoy this globe whatever size you choose. Regards Kevin

Epilogue
Dear all
Some of you may know about the "Museum of the Moon" which is a 7 metre diameter internally lit globe of the moon that shows around the world I have seen this moon and it really was a great experence It was conceived by artist Luke Jerram (here is his web site https://www.lukejerram.com/ Since the moon he has produced "Gaia" (a similar sized earth globe) (I have not seen this) According to his web site he is now working on this Mars! Regards Kevin

Coming from the other side of the SVG -VS Pixel question:
Most photographs have a discrete number of pixels. However, many modern cameras have a ridiculous number of pixels available. two things can trip you up, though: Cheap programs, like Paint and such will automatically reduce the resolution of your image to reduce memory needs. Or the photo may have been saved in a lower resolution. Either way, you cannot get extra pixels back. Scalable Vector Graphics, OTOH, are computer-drawn images which are saved as a set of lines, boxes, circles etc, . . . that have a mathematical relationship within the image rather than a fixed number of pixels. So, no matter how large you scale the circle, it will still be smooth. Lines will be the same since the slope is calculated for the scale. This is why when looking to scale drawings, it's much better to look for proper SVG files since many people who are not aware will often save in a pixel format that looked fine on their monitor, but doesn't scale well. If you are dealing with photos, the best you can do is just look for the largest resolution you can find and hope it has enough detail to scale as much as you want it to. |

This is an outstanding, and inspiring, build thread.
I have always wanted a gold of the Moon and Mars, and a couple pf other planets...maybe... This makes that childhood dream very possible! Much appreciation! I have to just get the templates now, and then get A LOT of duct tape...

Very interesting thread. Having a Moon or Mars model on my desk is now on my wish list :-) Thank you!
