Thanks, Asphyxia. Interesting to know that. And thanks for responding: I’d begun to worry I’d chosen too old of a post to get a response….

I was wondering: what’s the smallest possible resolvable objects with the orbiter’s resolution? Any chance of getting direct images of any o the lunar landing sites, to see how they’ve aged? I remember reading on the Bad Astronomy site about why nobody has been able to take pictures of these sites before (too far away, so even high-power telescopes can’t see anything that small). Is this one powerful/close enough?
”

The resolution of the TMC (Terrain Mapping Camera) of Chandrayaan-1 @ 100 kms above the lunar surface is 5m. So its unlikely that it can take pics of any of the lunar landing sites.

By the end of the mission, if they decide to lower the orbit to say around 25kms, the resolution will go up to 0.3m, at which the lunar landing sites can sure be pictured. It depends how they decide to wind up the mission.

It is clear that the image is a fake. How can it all hang up there in the sky? Einh? Look! Only half is shown. Old Indian rope trick. So, it means someone is sitting on the either side and holding it all up. If you ask them to show the other side, then he will change sides. So, they will never let you see the whole thing. Just bits of it.

Only way to authenticate that the world can be held up like that, all by itself, with nothing under to hold it all up is to send an international team headed by an honest person. Do you know of any honest person today? No such thing. So it can never be proved that the great orb in the sky is just hanging there.

Just my opinion.

I am an Indian and experience of watching this picture is as follows;

All my youger years I wanted to have a camera anc click my own pictures. When I got my first camera I saw the first picture that I clicked I was proud and inspired.

All these days Indians have seen pictures of moon and other planets taken by cameras of other countries but this one comes from our own.

I that is the importance of Moon Project. We know US and other countries have gone there before and there are a lot of study material avaiable but you never really learn if you dont do it yourself.

Actually, I should have mentioned that the Indians would probably be pretty good at Australian geography. In the second (southern coast photo) they would most likely have determined that the left nearly shows the WACA (Western Australia Cricket Association) ground in Perth, and on the right (before it disappears into clouds) is the Adelaide Oval (Adelaide, capital of the state of South Australia). Buried under the clouds on the right, of course, is the Melbourne Cricket Ground.

Trust me, judging by all the Indians I’ve ever worked with, navigation by cricket grounds would be the least of their skills.

Hey folks,
Just because you thought South was UP, why is that wrong.
If we had south pointing up, us Aussies wouldn’t be “down-under” any longer!
