hey maybe....it looked awful hazy too. I don't know if that would have an effect

Ian - Totally. Earth is 7 light minutes away from the sun, and 15 light-minutes away from mars. So, it's much farther away, and the viewing angle will be
much smaller.
On Pluto you can barely see the sun as something different than other stars already. |

Ah, that explains it. I did wonder. That is fascinating information about Pluto.

that's amazing.
There was discussion in my geology of the planet course I took a few years ago that the sun when younger burned too hot for earth but Mars could have had earth like conditions because of the intense heat of the sun when it was a new star

O.K., but sometimes, under certain conditions, the sun setting looks that small here on earth, too. In fact, I wouldn't guarantee that that photo was taken
on Mars.

Saundra, that is interesting. I remember seeing a computer image of what Mars would have looked like when it once had oceans. I have a book by a space artist
(David A. Hardy) who does such paintings.
Karen, the photo is of Gusev Crater. It is from the Mars Rover website. It was the winner of a competition for the most popular photo. Or are you a conspiracy theorist?

No, Ian, not a conspiracy theorist. Just a skeptic. (Is that how that word is spelled? It looks odd to me just now.)
And I always think atmospheric effects are odd -- probably because I don't really understand them. Sometimes the moon comes up here in the east, early in the evening and it looks so clear, so blue, so enormous it is just stunning. Other times it's just a little white blob. And other times its even bigger and it looks yellow or orange! Sometimes, when we're in Mexico, I see the sun going down behind the ocean -- so to speak -- and it's just such an enormous ball of fire that I swear you can almost hear it sizzle when it drops into the water (just kidding, of course), other times it's just a little yellow lemon drop of a thing dropping below the horizon. Don't try to explain all the ways those things happen. I'm post-menopausal, have no memory, and I won't remember anyway. OR, do try to explain them and I can come back to this thread every time I get curious about these things.

Ah I see. At first I thought that you were suggesting that I had come across a photo of Earth and thought that it was Mars then I realized you might mean the
government had faked it. As for the Spirit Rover it cost something like $400 million dollars and was worked on by hundreds of people of different
nationalities. There are photos, videos and eye witnesses of it being built. There are many people involved in transporting it to the launch pad. The launch of
the rocket was witnessed by hundreds of people with their own eyes and all around the world on T.V. You can hear it from five miles away. People even track
them with telescopes. The rocket will show up on radar/satellites and other countries such as Russia will be aware of it and tracking it. When on the surface
of Mars the rover cannot send a signal direct to earth. It has to send a signal to one of two satellites orbiting Mars and those satellites then transmit the
signal to earth. It takes ten minutes for the signal to reach earth. There are so many people involved around the world in different capacities. Even with
current special effects technology the photos of Mars could not be faked. The Mars Phoenix Lander was photographed by a satellite orbiting Mars as it
parachuted towards the surface.
The more you look into it the more you realize it is not something you can fake in this day and age. Nowadays space is an international venture.
Why would anybody want to fake science? There are so many thousands of people around the world involved in these space ventures that to fake it would be as great an undertaking as faking air travel. Then again there are people who do not believe that the holocaust happened (Mel Gibson and/or his father) and people who believe the Earth to be flat. Check out this man. The funniest bit is when his wife is outraged when she visited England (Australia being the opposite side of the world) and people kept asking her 'Are you from "down under"?' She insisted that she had not been hanging upside down from her feet. "Marjory has always known that the earth is flat, too," says Charles Johnson. "As far as she knew, everybody in Australia knew it. She was rather shocked when she arrived here and found people speaking of Australia as being 'down under.' It really offended her. She would get in quite heated arguments with people who seemed to accuse her of coming from down under the world." Ultimately, Marjory Johnson swore in an affidavit that she had never hung by her feet in Australia.

I don't understand science and I still think the world is flat. I may know nothing about science but I think regardless I am entitled to my opinion.

Sheep, the more educated your opinion the more you are entitled to it.

I saw a dog cross the road the other day but I am not sure it really happened.

Sheep, as I have been telling you for over an hour it was captured on CCTV camera.

I am not interested in your science. I am entitled to my opinion and I just like looking at the sky.

Other people saw the dog, Sheep.

Talk to the paw because the Sheep don't want to hear your science no more.

Ian. I realize you are very smart and have an interest in the higher sciences but I really must object to how you keep putting Sheep down. He has a right to
his own experience with science and reality.

You are right, Saundra. I apologise, Sheep. You are entitled to your opinion/beliefs that the world is flat and the dog you saw didn't cross the road.
