Mars Rovers Still Going Strong, Mission Extended

Loconut1389 writes "The Mars rovers' missions have been extended from 90 days to about 250 and have been upgraded with some new software to give them extended single run distances as well as other features. Yahoo has a similar article, also at Reuters. I think it's great that these initially plagued robots are doing more than expected and are still going strong, mostly thanks to engineers figuring out how to make the most of the software and hardware onboard and figuring out how to diagnose an unfunctioning, unresponding machine millions of miles away. The whole project amazes me and I'm happy for NASA to be getting some good news for a change."

    How even though given the anti-intellectual culture of the US we are still the only ones able to land this very successful rover, and I feel the world actually respects the US for it(almost makes up for the other stuff), unfortunately, unless we get more kids interested in science, and more funding for research, the rest of the world will quickly catch up and surpass the US. Hopefully having this mission be more than anyone ever imagined, it will counteract both of these things.

      This 'freedom' reason for innovation is rubbish, Americans seem to think they're the only 'free nation' in the world, when in fact nations have been 'free' for hundreds of years before America existed. It comes down to money - the US has a bigger population and a bigger economy, more money for projects like this.

      If any other European country etc put their mind to it then they could easily match NASA too, it just seems that it's only NASA in this world which is willing to spend (waste IMO) huge amounts of money on very little gains.

      Looking at the amazing inventions, discoveries and adventurers from Europe, particularly during the Victorian and Edwardian eras, gives me the impression that the Europeans have the "Right Stuff" too. The problem may very well be that those inventors, discoverers, and adventurers weren't hampered by legalities and red tape as they are now. Also, America wasn't ravaged by two great wars. Sadly, even without the wars, America has been heading the way of stagnanation in creativity due to legalities and red-tape (patents and lawsuits are only symptoms of the problem).

      Despite not having the same rigorous educational system, when Europe passed the torch to America, our creativity (which was also present during Europe's creative height) is what kept us ahead of other countries where governments kept tighter control over their citizens' behavior. We've proven that it isn't Math or Science that gives a country an advantage, it's the creative use of them, even if your average citizenry shows lower math and science proficiency than in other countries. However, in this current American era (really quite short in European standards of achievement), control appears to be more important than independent thought and invention. Unfortunately, control stifles creativity, just as it stifles liberty.

      I'm sure it's gotten worse since

      It has, and it's going to get worse, due to those fine republicans abolishing the "Death Tax".

      The estate tax existed solely for the taxation of the super-mega rich. Less than 1% of Americans were affected by the "death tax" (the upper 1% make salaries starting at $400,000/yr). The richest 300 families in America collectively contributed about 20% of the estate tax. Annually, by 2010, the estate tax would have put $60,000,000,000 per year into the government. For estates worth over $10 million, on average, 56% is yet-to-be-taxed capital gains.

      Now, however, the solution to step 2 is easy: die.

      Step 1. Buy stocks, ventures, etc.
      Step 2. Die
      Step 3. Kids inherit without having to pay capital gains taxes.

      It was touted as being a measure to save small family farmers and the like. The problem was, of course, that the first 2.6 million dollars of inherited farming or small business wealth was already exempt from this tax.

      So, funny thing happened: Democrats proposed bills to exclude the first $4 million per couple from estate tax. Shot down. Then they tried $8 million. Shot down.
      Then Sen. Fiengold (D-Wisc) proposed a bill that would exclude the first 100 MILLION from the estate tax.

      The bill was shot down 48-51.

      Now, thanks to President Bush and the Republican Congress, if you have enough money, only one thing in life is certain. Death, or taxes.

      We're not all rich over here in America. The combined gross income of my wife and I this last tax year was under $20,000. Yet, I support tax dollars going towards space exploration. I just wish that people who could actually afford to pay taxes supported it, too.

      Actually this is just a game to set the right expectations. They designed whole thing with a much larger project life right from the beginning.

      This is utterly untrue. I have been working on the project since 2000 and allow me to explain where the 90 days figure came from.

      It's rather complicated, however it boils down to how many solar panels they could bring, and how fast reduces the effectiveness of the panels. They tried everything they could think of in the lab to figure out some way to remove the dust from the panels however that proved to be something they could not solve, so they took data from the mars pathfinder mission, and came up with a number describing the conservative estimate for the lifetime of the solar panels given the dust on Mars (and remember, Mars has a lot of dust).

      I've talked to mission physicist Geoffry Landis about this extensively and I have seen the data, which basically indicates that the rate of power dropping is about half of what we expected. This is very good news! This means we have a good shot at a very long extended mission, because if it continues at this rate, eventually the solar days on mars will increase in length faster than the dust buildup occludes power collection. It is believed therefore that the solar panels will not, as expected, be the final limiting factor on the length of the mission.

      However, because that number was basically 90 days, every other instrument on the craft was designed to last at least 90 days, but not necessarily any longer. There are many motors that have a very short lifespan, which could now very easily fail at any time now. This includes a Rock Abrasion Tool motor, along with the azithmuthal actuator for the Pancam Mast Assembly. Also the wheel motors are put under a lot of stress and so they are good candidates for failure. Also, a single thermal failure in the middle of the night can destroy the Mini-Thermal Emission spectrometer, and the other spectrometers are not very useful if the Instrument Deployment Device fails either.

      NASA played the same "stay on the safe side" tune on many otehr missions - see for example the Voyager missions, etc.

      It is true that NASA made conservative estimates for things, which is proper engineering practice in situations that are as unknown and dangerous as this. I do not believe NASA was covering their own butts so much as trying to figure out how to use the 90 days they thought there were mostly guaranteed as best as they could, and then deal with more as they came.

Another part is that many engineers and researchers are not educated in the USA, i think about a third of all phd positions iirc. Another problem which complicates the whole thing is that many big companies got research labs in other countries, but their inventions count as american ones, since they got patented in the USA first (e.g. IBM).
