Mars Rover Ready for Risky Descent into Crater

Riding with Robots writes "After months of scoping out the terrain, the robotic geologist Opportunity is ready to drive down into Victoria Crater on the Meridiani Plains of Mars. Mission managers acknowledge the hardy rover may never come back out, but say they think the potential for discovery is worth it. 'The rover has operated more than 12 times longer than its originally intended 90 days. The scientific allure is the chance to examine and investigate the compositions and textures of exposed materials in the crater's depths for clues about ancient, wet environments. As the rover travels farther down the slope, it will be able to examine increasingly older rocks in the exposed walls of the crater. '"

    I think it will survive it. Obviously that sucker was built Tonka tough lol. It's funny though cuz every time it's about to do just about anything, the scientists say "well this might be the last thing it ever does" just because it's way past the 90 days. It's kinda like how people every year say "yep, those AS400's are on their way out any day now" and then there I was, still sitting in front of an ugly green screen for one of my classes (I changed degree fields after that) I think the rover will be there long enough to bump into an astronaut's foot lol. Unless of course it gets attacked my martian crater monkeys. Those things are vicious.

      It's similar to landing in the middle of the Sahara Desert with no way to get out: you know there's something interesting far away, but the only way to examine it is to plan another mission, rather than just drive there. After everything in the crater has been examined, if there's no other scientific targets within range, the only objectives remaining are engineering ones, which are also important, certainly more interesting than just turning off the "little rover that could".

      Well, if you wanted to build a rover that'd last for a long time in a desert-like environment then I don't think you'd have problems finding a contractor to do that. It's not like regular cars die from travelling through desert areas, and top it off with high quality seals and whatever it should last until it breaks down internally (or the wheels are broken, IIRC one of the Mars rovers is limping.

      It's when you say "build us that rover, but after three months it'll have to run on no power" that things get ugly. The solar panels were supposed to get clogged up with dust, and someone really did think it'd go on for many years instead of months they were damn silent about it. It's like thinking you're building a laptop with a battery, only to find out you've got line power. That would throw your estimated operating time off by several orders of magnitude too.

      While the idea they said three months to get the funding is entertaining, there's really nothing to suggest that was actually the case. They're scientists doing an experiment, thought they had a limiting factor which was wrong. Now we know that if we go to Mars, we can build solar panels that won't clog and will be a pretty much permanent power source which changes everything. Maybe someone hoped, dreamed or wished for it but I doubt many if any knew and said "hey, let's go wih three months anyway".

    But where does this confidence come from that they know that all of these formations are caused by water?

    We use our experience on Earth to form a hypothesis about similar features on another planet.

    Every week that goes by, our probes and telescopes bring more unexpected observations. Our theories of the universe are constantly changing. Objects that we thought were completely different increasingly appear to have similar characteristics.

    We form a hypothesis but we can't support or deny it until we observe evidence. If the evidence supports then it looks like we knew it all along. If the evidence denies then it raises more questions.

    As far as I can tell, nobody's ever even observed an impact occur on any planet.

    We have observed minor impacts on the Moon and a major one on Jupiter.

    At some point in time, their speculation hardened into consensus without ever thinking to validate it. Many of the craters we observe in the universe have highly unusual features that don't appear to strictly correlate with physical impacts.

    Consensus is built with mathematical models. Probes and telescopes are used to validate our hyptheses. Again, if observational evidence does support a hypothesis then more questions are raised and new ones are formed. As for not correlating with physical impacts (I'm not entirely sure what you are referencing here) there are craters formed by volcanoes and probably some caused by exploding meteors (meteorites).

    My point is that the overall predictive track record and the large number of unsubstantiated consensuses within astrophysics today do not support the notion that we should be able to accurately predict our findings on Mars at this point in time.

    We have hypotheses. Yes we want water to be found on Mars and it shouldn't be unexpected. There is an incredible amount of water in the universe and it would be foolish to only expect to find it on Earth or the moons of Jupiter.

    Mars was a molten ball of magma that eventually began to cool. Why would anyone not expect that sometime between being a molten ball of magma and its current state as a presumably cold, dead world that there wasn't flowing water on it?

    Hmm. I agree and disagree. On the one hand, certainly astronauts help sell NASA to the public, which probably helps keep NASA in the budgetary eye. On the other hand, one of the reasons NASA is so f***ed up is because they are mandated to spend money on various projects in various politician's districts, which is what they truly care about (mmm, love that pork).

    So I would say that as long as the sweet, sweet money was being spread around, the politicians would be happy. And if we truly had 1,000 probes constantly sending back neat-o images and data, I bet the sheer volume of discovery would actually exceed the romance of humans in space.

    The scientific goals of the rover missions are to gather data to help determine if life ever arose on Mars, characterize the climate of Mars, characterize the geology of Mars, and prepare for human exploration of Mars. To achieve these goals, seven science objectives are called for: 1) search for and characterize a variety of rocks and soils that hold clues to past water activity, 2) determine the distribution and composition of minerals, rocks, and soils surrounding the landing sites, 3) determine what geologic processes have shaped the local terrain and influenced the chemistry 4) perform "ground truth" of surface observations made by Mars orbiter instruments, 5) search for iron-bearing minerals, identify and quantify relative amounts of specific mineral types tha contain water or were formed in water, 6) characterize the mineralogy and textures of rocks and soils and determine the processes that created them, and 7) search for geological clues to the environmental conditions that existed when liquid water was present and assess whether those environments were conducive to life.

    Very limited, very specific. Hopefully one of the first Mars landers, not the last. It took some five years (IIRC) to go from that paragraph to the actual spacecraft. During that time there were innumerable meetings / arguments / pointed emails about what scientific packages would fly on the landers. Some of those decisions were likely pretty prosaic - It might simply have been that they actually had some or all of the technology in a package that could be built and tested in the time frame and budget allotted.
