Re:False color?
or is it something NASA arbitrarily adds to impress viewers with notions about "the red planet"
It's a fairly accurate representation of what Mars would look like to the human eye.
The thing is none of the cameras on board the rovers or Phoenix take pictures in a "conventional" manner. Instead the imaging devices have a series of filters designed to focus on a specific range of wavelengths (ultraviolet, infrared, etc.). Those black and white images you see are the results of a picture being taken through one of those filters. This is why some images of the same scene will appear darker than others.
NASA can then take these images and composite them together to give a representation of what the surface would look like to the human eye. -
Re:First Mars Blooper Released by NASANASA is posting high resolution pictures daily.
Phoenix and the American Flag on Mars
This image, released on America's Memorial Day, May 26, 2008, shows the American flag and a mini-DVD on the Phoenix's deck, which is about 3 feet above the Martian surface. The mini-DVD from the Planetary Society contains a message to future Martian explorers, science fiction stories and art inspired by the Red Planet, and the names of more than a quarter million Earthlings. -

Re:time to innovate
The experiment of exposing an unpressurized hand to near vacuum for a significant time while the pilot went about his business occurred in real life on Aug. 16, 1960. Joe Kittinger, during his ascent to 102,800 ft (19.5 miles) in an open gondola, lost pressurization of his right hand. He decided to continue the mission, and the hand became painful and useless as you would expect. However, once back to lower altitudes following his record-breaking parachute jump, the hand returned to normal.

There you have it, you don't explode in space. Your skin is actually very air tight. I think the worst thing that could happen is your bladder would become inverted. Think about it. Ouch! -
Re:hmmShame they did not land near the other probes, then they could have filmed each other. Yes, I know that is scientifically pointless, but you have to admit it would have been cool. We have pictures of the descent however. And beautiful pictures

Re:Anonymous Coward
Heck, I don't think this is a troll - it's an interesting question. So I looked, and found this:
Abandoned Spaceships on the Moon
Basically, the Lunar Reconnaissance Orbiter will get some 0.5 meter resolution pictures of the Apollo landing sites. It launches sometime after November 28th of this year (which really is 2008 - the government's telling the truth on that one). Enjoy! -

Re:The good news
It appears that there is some kind of toilet on the Soyuz module, though I would guess that it probably doesn't have as much capacity or functionality.
-
Re:Wow
I'm not so sure about a rover like the ones we've already sent. But a little bulldozer would sure be cool. My biggest WTF? moment learning the details of this mission was when I found out that the robotic arm could only dig down about 3 feet. 3 feet? What if it finds the beginning of something interesting just as it's reaching maximum depth? With a little robotic bulldozer, it could just keep digging deeper. With the arm, we're pretty much stuck designing a new craft and waiting for it to get there.
On a side note, I found this picture and caption interesting. http://www.jpl.nasa.gov/news/phoenix/images.php?fileID=9353
Does anyone know the criteria that was used to pick out the quarter million names that they put on the DVD? Seems like too many to choose them individually, at some point they almost certainly had to resort to a "pick random names from the phonebook" methodology. Would be interesting if the list was available online somewhere so we could all go and see if our name made it to Mars. -
Re:Electric universeNo-one has yet observed any dark matter, so it is just still a theory.
There are other explanations, including 'Gravity doesn't scale like we thought it did'. It's of course unclear if this is really dark matter, it being dark and all, but I think it's still twisting facts to claim that dark matter hasn't been observed at all. *Something* has been observed, so it'd be more fair to say something like "observations of dark matter are still very uncertain". -
Re:Where on the planet did it land?
Here's a graphic of where it is on the Martian globe:

Re:Interesting Object?
It could be the metallic glint from the heat shield or the backshell. They are detached at, oh, I think it was a kilometre or so off the ground, and impact onto the surface quite some distance from the lander. That was the case for Spirit and Opportunity, the latter of which even drove up to the heat shield and took a closer look.
They will probably be able to tell if that is what it is when the MRO orbiter takes pictures from orbit. If it is the heat shield or backshell it will be in the direction from which the Mars entry occurred. -
Re:Where on the planet did it land?
This will show you location and local (Mars) time for Spirit, Opportunity, and now Phoenix.
-
Re:Somewhere in the red circle...
Yeah, they didn't stick a scale on it. The latitude/longitude grid helps, but only if you remember that Mars is smaller than Earth and do the calculation. Here's something more tangible, assuming you know how big Long Island, New York is. According to the text on that page the landing ellipse is 70km long.
-
They caught it on way down
Apparently they were able to image the thing from orbit while on its way down on the chute:
http://www.nasa.gov/mission_pages/phoenix/main/index.html
They mentioned giving it a try at a press conference, but gave it really small odds because the image size is much smaller than the potential landing range drift. Lucky hit. -
Re:Color Camera == 3 B&W CamerasYip, a fellow slashdotter found the smoking gun in another story that it's a 2-filter "partial" fudge:
http://www.nasa.gov/mission_pages/phoenix/images/press/false_color_postcard_edr.html"This is an approximate-color image taken shortly after landing by the spacecraft's Surface Stereo Imager, inferred from two color filters, a violet, 450-nanometer filter and an infrared, 750-nanometer filter."
When the press copies it, they usually fail to mention such. -
Re:Wow
And I can't just remember what the other stuff is called, but it ain't dirt.
I think the fancy word you may be looking for is sand. NASA uses all sorts of fancy words, such as dirt & soil.
Go ahead and call it dirt. -
Re:Colour Imaging?
Situated atop an extended mast, SSI will provide images at a height two meters above the ground, roughly the height of a tall person. SSI simulates the human eye with its two optical lens system that will give three-dimensional views of the arctic plains. The instrument will also simulate the resolution of human eyesight using a charged-coupled device that produces high density 1024 x 1024 pixel images. But SSI exceeds the capabilities of the human eye by using optical and infrared filters, allowing multispectral imaging at 12 wavelengths of geological interest and atmospheric interest.
My Nikon D50 captures some of the UV and IR as well. That's the other reason everyone uses a UV filter on their lenses (the first being, it's a cheap way to protect the camera lens that might well be worth more than the camera). With a special filter, I can take IR pictures with my Nikon. Even your eyes pick up a bit of the UV -- if you look at a blacklight bulb, it's hard to focus on -- the lenses in your eyes focus visible light and don't do as good a job on the UV. -
Re:Colour?Why are the photos black & white?
Because with that particular camera, taking an RGB photo involves making three separate exposures with different filters, transmitting the result back to Earth, and combining them. Given that the lander has been on the ground for less than 24 hours so far, they're still at the quick-glance-around-to-see-where-we-are stage and don't want to waste bandwidth taking the same picture three times. Give them time. Given the PR value of RGB images I'd expect some to start showing up within a few days.
(In fact a two-colour image has shown up already, but it's not true RGB and probably isn't what you're looking for.)

Re:Where on the planet did it land?To answer my own question...
http://www.jpl.nasa.gov/news/phoenix/images-all.php
That seems to have just about everything, plus some earth comparisons that should give you an idea of where on Mars it landed.

Re:Prime Meridian / I Had No Idea
I had no idea the Air Force was involved in this mission. It's clear they are because of the green blobs in the right lower corner of the map which are apparently a golf course adjusted for lower gravity and reduced atmosphere.
Alan Shepard was US Navy and the first extra-terrestial golfer. Your comment woke old memories of watching the coverage. -
Dear NASA: Hire an editor, please!
There is a repeated error on http://www.jpl.nasa.gov/news/phoenix/images.php: The caption used for many images should read Team Members Celebrate and not Team Members' Celebrate
(Unless they really meant to write Team Members' Celebration?)
Let's just hope there are no misplaced apostrophes in any of the wee beastie's code. Especially in the firmware update upload controller. That would be delightfully ironic....

Somewhere in the red circle...
Here. The blue ellipse was the intended landing zone, the red the actual, and the green box was... umm... a Martian football field? I dunno.
-
This clip...
here looks like the start of a BSG Episode. It's almost as if Moore has directed it - I expected number Six to turn up any minute, laughing, and invading our computer systems only to begin a sneak attack on the 13th colony.
Oh wait... this is reality ? In that case, I have another beer - make that five please.... And some peanuts. -
Re:How about telling us how many miles?If you use The Mars Climate Orbiter as an example of which units are used in what realms you'd quickly see that even in some of the most technical engineering houses there is still room for debate as to which units are appropriate where. For those too lazy to click through my link,
SEPTEMBER 30, 1999 Likely Cause Of Orbiter Loss Found The peer review preliminary findings indicate that one team used English units (e.g., inches, feet and pounds) while the other used metric units for a key spacecraft operation.

Re:Pictures [color] THEY'RE HERE...
They're 2-filtered. Violet 450-nanometer filter and an infrared, 750-nanometer filter. (As stated here.)

Re:lander, not roverI wonder, how long it would take either Spirit or Opportunity to drive there from their present locations if something interesting was found? Longer than it would take to plan, design, build, launch, and land a rover right there, I imagine.
In the years it's been on Mars, Opportunity has only travelled about 11.6km. Spirt is about 7.5km. http://marsrover.nasa.gov/mission/traverse_maps.html -
Re:NASA web site
I watched the landing live via NASA TV on the web - http://www.nasa.gov/multimedia/nasatv/index.html - and they did an AWESOME job. Why didn't you just tune in to that? I don't have cable TV or anything, but was able to watch the exact same thing my father was watching on his TV at home (he was watching the NASA TV channel via DirectTV satellite). Funny thing is that I called him to make sure he wasn't missing it, and it appeared that the webcast was about 40 seconds delayed compared to the satellite TV broadcast.

Re:Amazing how short sighted ppl are
Did I call it "Lander?" Dang, that's embarrassing. It's actually called "Mars Science Laboratory." Was in a bit of a hurry earlier, sorry.
