Evidence of Glaciers on Mars?
cyclop writes "Nature reports that the Mars Express mission has photographed evidence of ancient glaciers on Mars. It seems glaciers have sculpted valleys on the red planet, much like on Earth." Reader macguys writes "Space.com is reporting that the Mars Rover Opportunity has received an unexpected and unexplained power boost of between 2 and 5 percent. The NASA Rover site is so far silent on the boost."
I was under the impression the "unexplained power boost" was due to the fact that the Martian day is longer at this time of year.

This isn't the sig you're looking for. Move along.
well, at least the martians were kind enough to recharge its batteries for us...
The martians were trying to connect their iPods to the rover so they could get the latest U2 album.

Dust Devil Cleaning Services, the last remains of the vast martian civilization
I'm a dreamer, the world is my playpen. But hey, I'm a serious person, I can't dream all the time.
Maybe the drive wheel that was stuck freed up and and lowered the load. Or, more likely, a lucky gusty of wind cleaned some of the dust off the solar cells.

NASA announced that the rover's next destination will be the powerup that will give it rocket launchers.
If I have been able to see further than others, it is because I bought a pair of binoculars.
Someone should start up a site that everyone can place predictions and bets on the day that Spirit and Opprotunity dies.
It should be like the site that let everyone bet when the next big version of Linux was coming.

There is Jolt Cola on mars. This can only mean one thing. Martians are a bunch of jumped up caffiene druggies hiding out in their sophisticated cave strongholds and are currently planning to destroy the earth by sending their ancient glaciers here to be melted by global warming and thus submerging our free and democratic planet.
Why yes I have been listening to Donald Rumsfeld a lot lately, why do you ask?
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
Man, it's Friday, isn't it?

We will always have the homeless, whether we go to Mars or not.
Not if we send them to Mars.
You've got to be joking. Space exploration holds not only the future for our species (Earth isn't always going to be habitiable for us, especially the way we're treating it), but endless possibilities of discovery. Isolation never has done anyone any good, and that counts for staying planetside as well. We could easily fund social programs like you're talking about if everyone actually got up and contributed more to the communities that they live in. When was the last time you were at your local elemenary school dropping off supplies, or handing out food to the homeless?

From the site:Seems that perhaps all those Slashdotters who always ask why wipers couldn't have been installed, or claim that dust was immediately going to kill power, can finally be silenced?
One aspect of a particularly long mission like the Mars Rovers is that it acts as a real-world test-bed for the new technologies. Maybe the dust buildup isn't nearly as big an issue as was originally thought, and maybe they've found a good compromise between power consumption and keeping the rover innards warm with the 'deep sleep' capacity. Still, the machinery will fail eventually - here's to hoping that however it does fail, it'll provide them with more information on how to improve things for future missions!

I'm not saying I don't like what the MERs have sent back, but some of the ESA stuff is pretty sweet looking
ESA's Mars Express
The ability to survive on the moon will require constant importing. It will need water. Nor will it be possible to colonize the moon to any great length.
Mars, OTH, can be truely colonized. It has water, O2, N2, Carbon, etc. It has everything needed, except that it has a thin atmosphere. It is possible that Mars actually has life on it as well.
Finally, how does this impact us (america or even the earth) today? Every time that mankind reaches, it has to develop new ideas and new things. these will always be applied elsewhere. NASA (and I believe the USSR's space program) caused numerous advances for humans, both directly and more indirectly.
I prefer the "u" in honour as it seems to be missing these days.
But if it existed then it was a long time ago. Plenty of time for all the evidence to be hidden beneath the sand. Mars is not exactly known for its non-sand storm nature.
Even if there are fossils to be found the chances of finding them with 2 little carts pottering about are about zero. It would be like driving around your local city and claiming there never been dinosaurs because you didn't find any.
At the moment what everyone is doing is speculating. Worse the speculations are based on very small samples and compared to only 1 planet wich we don't really understand yet either.
I have lived long enough to have gone through several cycles of mars having and not having water. The only thing I know for certain is that nobody knows for certain.
Could an intelligent species have lived on mars and left? We only recently discovered that a small species of humans has existed very recently very close by. Frankly anyone who claims to know the answer to what lived or didn't live on mars in the past is insane. You can guess. You can estimate. But certain we can't be. More fun anyway.

Uh... no. O2 is a byproduct of photosynthesis (well, more specifically, the electron transport chain in the tylakoid that obtains electrons from water to create reduced NAD(P)H, but that's splitting hairs). Life existed for a long time on Earth without atmospheric oxygen. In fact, the apparition of massive quantities of oxygen in the atmosphere was probably a disaster of cataclysmic proportions for many living cells back then (dead cells being notoriously unaffected by changes in the environment).
The fact that there's so much aerobic life as of today (there're still plenty of O2-less ecosystems out there) is just that organisms adapted to those rude algae and plants making O2 like crazy. It's by no means a requirement for life.

Very difficult to find-- I had to go to the Opportunity updates page and search for the first occurence of the word "power."

Glaciers carve rounded "U"-shaped valleys while rivers make pointed "V"-shaped valleys.
This does not take account of the uniquely Martian process of sapping which also creates U shaped valleys in dendritic, presumably fluvial valley systems. We need to be carefull about infering process from morphology alone.
