Funny you post this now... I'm sitting here reading 2001: A Space Odyssey for the first time, and Dr. Floyd just got up to the space station and marveled at the view of Earth from 200k miles up... Seems he was right. #rosetta
@Fremen9: Please share with me what it does represent. Technological breakthroughs? Achievements in science? Advances in communications, power collection from solar? Got it.
Or is this just one of those neato space pictures that get everyone all mushy; talking about how can God make something so beautiful, I feel so small, they should have sent a poet.... #science
@BlueBeard: Fremen9 did not call me an idiot. If you are referring to someone with an unusually low IQ, I don't fit that description either. Were I him, I would take offence to you putting your words in my mouth.
I agree, this image has nothing to do with God. I was merely mocking others' comments who so frequently do say that images like this are about God.
I'd like to know what you think about this image. And more curiously, what you think I think this is about - since you apparently know. #science
That is one serious telescope in mars... or is totally fake!.
For Earth & Jupiter to be on the same picture, considering Mars is between them in orbital distance to the sun, Mars would have to be positioned ahead of them in the orbital turn, having Earth closer , in a smaller orbit, and Jupiter would have to be Millions of Miles away on a wider orbit but still within the field of view of the telescope.
For Jupiter to be the appoximate size of earth in the photo, then Jupiter would have to millions of times bigger than Earth. It's only 11.2 times in radius.
Jupiter is 778 Million Km from the Sun. Earth is about 150 Mkm.
So in the best case scenario, We are 628 Mkm appart.
So there's no way that Jupiter at 11.2 times the size of Earth and 628 Mkm (minimum) away look practically the same size.
@aec007: Here is some context as to the position of the planets when this image was taken. I think you neglect to add into your numbers the distance from Mars to the Sun, and also relative to Earth and Jupiter in our orbits. Also, Also, more importantly, lens distortion (like when you zoom in your point-and-shoot camera lens apparent field of view changes) to take into account. #science
During this May 8, 2003 Earth / Jupiter Conjunction as viewed from Mars, the JPL Solar System Simulator ([space.jpl.nasa.gov]) provides the following ephemera...
Distance to Jupiter = 943.829 million km
Angular Size = 31.2" arc
Distance to Earth = 139.821 million km
Angular Size = 18.8" arc
With these figures, we see that Jupiter is 6.75 times further away than the Earth from Mars at the time of this conjunction. Since Jupiter is 11.209 times greater in size than the Earth; in this frame, it should have an apparent size 1.66 times greater than the Earth.
The angular size measurements given also support this, as 31.2 divided by 18.8 gives us a difference of 1.66 times. #science
@mattycakes: There is a lot of things that go by us and we never notice them. The things you find within the Vesica Pisces will for ever change the way you see life. I guarantee it. #science
It's amazing just how vast space is. And this is nothing. These are just tiny specks of dust that are pretty close together in the grand scheme of things.
Wow. He does know that there is absolutely NO way to accurately measure the temperature of the ENTIRE earth right? Maybe he can get Kumar to handle this. Oh, but only after Entourage.
It's called Global Dimming, and unlike global warming, they actually have quantifiable proof that it exists, thanks to 9-11 of all things. There was a documentary on PBS/Nova a couple of years ago about it. And they don't need smog to do it, the contrails created by airplanes do the same thing so there's no reason they couldn't pump mist into the atmosphere with the same result.
And apart from taking away valuable CO2 from real trees, how will this help? They will likely not be anywhere near complex enough to produce oxygen in the process, and it won't negate the fact that water vapor remains one of the most significant greenhouse gases. Real trees work, and will always work. There will never be a man-made product that can outdo life forms that have evolved and adapted over millions of years. Ever.

The landing sounds ambitious - awesome - sweet - too bad we won't be around after 2012 to witness it.

@Geisrud: you added nothing to the conversation. nothing.
except to remind us why it is so important that we take these photos in the 1st place.
so i guess a thank you is in order: thank you for reminding me what i never want to be. #science

What I did do, is elicit thoughts from others, towards others, and on their feelings towards this image. You're welcome.
Now, I'd like to ask you; why is it so important that we take these photos? #science
