where are the stars…why always stars miss in each and every picture of NASA.

Earth and Moon from Mars…

This is just an awesome pic:

That's us and the Moon as viewed from Mars.Â Very cool!

Hmm… I do not know about all the scientific and techy stuff about camera's and exposures and distances betwn earth/sun/mars moon at particular date and time….
but I showed this picture to everyone present today in my office (30 ppl) and EVERYONE thought that its a fake foto !!

Once you put this pic. as ur wallpaper on desktop… (1280*1024) …it appears even more manipulated !….

One would think that the Earth seen from Mars would be at least as bright as Mars is sen on Earth.

The stars cannot be seen in this photo because they are much dimmer than the Earth or Moon. They are underexposed. If the camera were adjusted to see stars, the image of the earth would be overexposed.

Mauro, looks like you might be correct. I did a quick check of distances (per the CalSky website) and on 15 October 2007 Mars was at a distance of about 0.87 AU, or 130344160.2 km, which is about 80.992 million miles.

Interesting.

Several things, I wonder how long the exposure was? And, considering the pixel density at that distance (142 km/pixel), would it be no wonder that a star did not make an appearance?

Thought it was worth asking…

How come this picture was taken from a distance of 142 MM kilometers and Mars at about rhis time is just about 100 MM away from Earth?

Its an us and them situation. They know something we don't and they're not gonna let on what it is. Its not just a secret, its THE secret…

It's a conspiracy, I tell ya!

Pshh…please.

The stars are missing because they've been removed. This is done in all images from Nasa and other organisations, it's NOTHING to do with exposure levels, etc. For some reason Nasa don't want us to see the stars.
Even when there's a full moon viewed from earth the stars are visible. Something "fishy" is going on here…

Observing the Earth/Moon system would be one of the joys of Martian stargazing.

Wonderful image when one thinks of the technology and the knowledge-imagination of those scientists and engineers involved that went into its final make-up. Rock on HiRISE and to all those involved in its creation!

Think about it !!!
Thats us down there walking around that round rock.
Its like Ptolemy said astronomy is the science of Gods…

It would be nice to see the unadulterated picture. I think they have added too much blue to the earth.

Yes, but then you would, of course, see a full moon and a full earth.

by the way.

this is more or less how you would see earth and moon from the sun.
The distance sun earth is 149 million km.
The distance here was 142 million km.

So this is what H.G.Wells/Richard Burton meant with 'Across the gulf of space…' Now I know what the Martians saw when 'They drew there plans against us'….

I believe there has been editing to this image… I think I read somewhere (BadAstronomy perhaps?) that the Moon was made brighter in this image. The Earth naturally has a higher albedo than the Moon, so the image was adjusted for symmetry.

Perhaps a couple stars were smudged out too.

Hi guys, me again, the 11 yr-old genius (not quite, but I am smart!).

Those conspiracy theorists are nutters, but I would like them to read me bed-time stories! Their ideas would make a fasinating book. I would buy it, no matter what the price.

Anyway, that is a gorgeous picture and the HiRISE did well on that one.

Eric, I agree. It is a great desktop picture!!

Conspiracy theorists would say that the Earth and Luna were just scaled models hanging in front of a black felt background.

Excuse me while I roll my eyes.

This is an amazing shot. To know HiRISE achieved that makes me wonder what else it can actually see on Mars. I wish the shot was a little bigger and had slightly better resolution. Aside from that, it makes a great desktop picture.

Earth and Moon here are very bright and wash out the dimmer background stars in the imager. Well unless you are a conspiracy theorist, in which case this is just like the moon landings, another fake-out by NASA.

The HiRise Camera has an impressive magnification, at a distance of 300km it can show details of 20-30cm per pixel, however the camera viewport is only 1,14Â° Ã— 0,18Â°. It is very likely that there are no visible (bright enough) stars in such an area that match the same exposure time as the bright earth and moon in the foreground.

If you were in mars orbit and looked to where the earth is supposed to be, you would only see a very faint dot, if anyting. And in very close proximity to earth, there wouldn't be any equally bright objects.

How come in the picture taken of the earth and moon, there are now stars in the background?
