Spirit Rover Begins Making Night Sky Observations
Nancy Atkinson writes "Even though the Spirit rover is stuck in loose soil on Mars, she has an overabundance of electrical power due to a wind event that cleaned off her solar panels. While MER scientists and engineers are having the rover take pictures of her surroundings in an effort to figure a way to get her dislodged, there also is enough power (since the rover isn't moving anywhere) to do something extra: keep the rover 'awake' at night and run her heaters so she can take images of the night sky on Mars. 'Certainly, a month or more ago, no one was considering astronomy with the rovers,' said Mark Lemmon, planetary scientist at Texas A&M University and member of the rover team. 'We thought that was done. With the dust cleanings, though, everyone thinks it is better to use the new found energy on night time science than to just burn it with heaters.'"
Who decided she was female?
Then, when they DO image something interesting, like this Martin crinoid, they won't talk about it!
If there really was to be a cover-up, wouldn't it be easier to just not release the smoking gun pictures rather than release and deny?

Is that what we mere mortals call a 'storm'?
At first glance, one might think that observation of the Martian night sky would return insignificant scientific data. After all, how powerful of a telescope does Spirit mount? Certainly not even in Hubble's league. But they aren't looking to collect data about distant galaxies & stars.
The real value is information about the Martian atmosphere. By observing the "twinkle" of distant stars, the observations should return some useful information regarding night time atmospheric conditions. Maybe not as much as a dedicated purpose designed atmospheric station, but certainly more than we have now.
âoeAny society that would give up a little liberty to gain a little security will deserve neither and lose both.
Sure, it does to me too, but that doesn't make it one. Take the famous Mars face photos. It looks like a face, under the right conditions of lighting and shading, but is otherwise an unremarkable piece of Martian real estate.

That this rover landed in 2004 with a planned mission of 90 Martian days and we're now in 2009 still amazes me. To keep these rovers functioning for that long is an engineering triumph. Even with equipment failures, dust storms, broken wheels etc. the engineers at NASA manage to make the best of these rovers and learn more about Mars. If we're lucky, the rovers will still be working when we land there, one day. It's nice to see such human ingenuity.
Such an amazing project, those little rovers are. With an planned life span of 90 days, they have now been running since...oh...2003? Wonderful work, NASA. Please keep the pictures and the science flowing. Can you imagine how long that data takes to get from Earth to Mars?
Or what about the communication path from the rovers to NASA? They use the Mars Odyssey or Mars Global Surveyor. Check this out. The rovers have a 250kbps link to those satellites. Unreal. Even with the satellite use, the data still takes TEN minutes to get to Earth.
This stuff is awesome. Just awesome.
Please, please, please...make a photo of those two moons on night/twilight sky, with barely visible ground/horizon
Ultimate romantic picture for all geeks throughout the world ;>
One that hath name thou can not otter
It's not just nautical tradition. In English, anything of "common" gender (i.e. persons unknown or groups of mixed gender) get masculine pronouns, while anything ordinarily neuter but "personified" gets feminine pronouns. There were some archaic examples of personification from neuter to the masculine gender, of which see Fowler's for details, but these mainly follow Latin gender categories; modern usage of the gender of personification favors the feminine, as far as I know, exclusively.
Good, F%&king god, man. Did you seriously post a link from Richard C. "Art Bell's Best Buddy" Hoagland, "winner" (read: purchaser) of the Angstrom Medal, science "advisor" to Walter Cronkite during the Apollo missions, Mister "Face On Mars", glass tunnels on Mars? Did you seriously post that tripe on this site?
Do you believe:
You do know that this is /. and not the "News of the World" site, right?
Politics is the art of looking for trouble, finding it everywhere, diagnosing it incorrectly and applying the wrong fix.
As the article says, they trail after a few seconds, since they can't track. So they can't take deeper images of fainter objects. Without the ability to track, they might as well point the camera straight up (or whereever) and check for meteors. Apart from getting information about how many strike the martian atmosphere, they could correlate counts with meteor showers on earth, to see how the same showers impact (or not) two planets at the same time - a unique opportunity.
Also, a lot of metoers on earth at least, are fairly bright. So they might get quite a good hit-rate with their cam. Although I don't know what effect the thinner atmosphere would have. It would be interesting to see if the thinner atmosphere made meteors burn brighter (as they'd be slowed down by "air", less) or less bright, due to the lack of gases.

*raises hand*
Between the Martian pics, Hubble, and APOD (Astronomy Picture of the Day), we have enough pictures to last a lifetime...or at least until Microsoft starts charges us to change wallpaper. Hohoho.
I think it would be interesting seeing a picture of Earth taken from Mars.. even if it was only a faint dot of light in the sky. I imagine the cameras could do this even if it isn't a great picture.

I doubt he read what you wrote. I didn't.

If you're wondering why they don't make "true color" images, it's because "true" colors aren't scientifically useful. They choose the color filters very carefully to give them the most useful images for seeing certain things, not so that you can get "true color" pictures.
But then I read the second part of your comment and realized nothing I say will be understood.
I forgot to mention that there is a book called "Postcards from Mars" that has some wonderful color images (true, approximate, and false color) from the rovers. It is a bit dated in that it doesn't include some of the newer places visited, but still a very nice coffee-table book.

Sadly, the cameras are so dusty now that they cannot take very good panoramas anymore. However, I was wondering if they couldn't clean up the images because the dust fuzz should mostly be the same for any given sun angle. In other words, subtract out the known noise pattern. It would probably have to be done by an amateur because NASA doesn't have a lot of spare funds for that kind of activity. Panoramas involve dozens if not hundreds of smaller images. An amateur cleaned up some of the earlier Soviet Venus lander images, and did a bang-up job. He even made some discoveries of unknown detail partially hidden by haze.
