      You could launch 50-500 (depending on your cost estimates) robotic mars missions for the cost of one manned mission, each exploring a different aspect of the planet. Pardon me if I think "better on the fly decision making" isn't worth 49-199 missions.

      You are pardoned. And incorrect. The two rovers in question cost 600M combined, and each year beyond the first is apparently costing nearly 3 million dollars per month, at the cost of leaving 2 days a week for the rovers to sit and recharge.

      So, using the actual costs (not estimates) and assuming the distribution holds by using the same rover design just sending more of them.

      50 missions will cost about 20 billion dollars. 500 will cost you in the neighborhood of 200 billion dollars. No, economies of scale don't apply too well yet to launches and any cost benefits seen in launch costs will apply to manned missions as well so they are negated in your argument.

      The Mars Direct plan was cost analyzed in 2004 by NASA and the ESA. NASA estimates the high end of 39.4 billion inlcuding the first mission, with follow on missions running 7 billion. The ESA has these figures at 26.6 and 5.2 billion respectively. Note these are six month on planet stays by four to six scientists, with a few tonnes of scientific equipment, and rover-vehicles capable of covering around 150+ Km/day. The cost of this would be spread out over about 5-12 years.

      Thus the cost of your 500 roborover "plan" - which would have to cover a time span of over a hundred years if we could launch five per year - would pay for (200-40 = 160; 160/7 = 22) 23 manned expeditions to Mars using the much more expensive NASA calculations. Using the ESA costs your 500 roborover "plan" would pay for (200-27=173; 173/5.2=33) 34 manned missions to Mars. Again, assuming no benefits from economies of scale, and rounding in favor of higher costs.

      However, the manned missions as specced out have so many redundancies that after the first dozen or so you could continue the same missions requirements for about 50-65% of the cost due to on site capabilities from previous missions. But we'll leave those out of the equation.

      Also, assuming every other year launches for the manned expeditions gives is a time span of less than a hundred years. Annual launches would mean 24 years from the first launch. Add in 6 years of prior development and that's 30 years.

      The area that can be covered by this mission design would take nearly 50 rovers of the current design about 60 years to accomplish when calulating time to arrival and assuming each one can operate for 4 years at full power (hardly a reasonable assumption at this time). Given the 6 month stay and rover vehicles, a four man team can cover up to 27,000Km of Martian surface. At 100m/day how many rovers will be needed to cover that same amount of ground? If we can get 2 years of them ... about 90 IIRC. 90 roborovers will run you about 36 billion, and many many years.

      Don't kid yourself. Far, far more science will get done with robotic missions for your dollar.

      It seems it is you who is kidding us. Robotic exploration has it's place, but it is foolish to assume it is the most cost efficient manner. Robotic exploration is best suited for determining the best landing sites and on planet resources for the follow on human landings.

      Read the reports. The GCR risk has been heavily overstated. The National Academy of Sciences' BEIR report puts the estimated risk of fatal cancer at 1.8% per 100rem for men and 1.35% for men (reduced risk of breast cancer).

      GCR for the trip there and back is expected to be 31.8 rem for the conjunction class trip. On planet exposure is approximately 10.6 rem. Thus the expected exposure to GCR over the whole trip is 42.4. This means that the increased risk of a fatal cancer developing over the remainder of the astronauts lifeitme is less than 1%.

      Curious that you asked about GCR, not solar flares. Flares are the larger danger in transit as they are bursts, not a little over a long time. Sudden doses of radiation are more dangerous to astronauts than long term low level exposure.

      Of course, these are easy to shield against as the layout of the hab and supplies handles that for you. Thus, depending on solar cycle the average dose from solar flares over the course of the trip is 5.5 during transit and 4.1 on planet.

      This brings us a total average dose expectancy of 52rem for both GCR and flares. Again, the risk exposure is about a 1% increase in the risk of fatal cancer. So you see, once you know the actual details radiation is not a significant risk. The launch is a more significant risk than the radiation. Heck driving to the launch site likely carries a higher risk of fatal injury than the radiation risk.

      If non-smoking astronauts had a 20% chance of developing fatal cancer before the trip, they raised their chance to just under 21% after the trip.

      We've had ongoing test and development for several years already (and some aspects for a decade). The crucial aspects of the MD reference mission are actually better tested than the crucial components of Apollo. Indeed, most of MD will be far better tested than Apollo even aspired to.

      Funny, because Oak Ridge puts 400 Rem as the standard "doubling your risk of cancer" amount:

      http://www.ornl.gov/info/reports/1991/3445603349 17 9.pdf

      They also state "Recent risk studies suggest annual exposure guidelines should be reduced by a factor of 10".

      They cite GCR numbers of 5.3 for exit/entry of Earth, 20 rem/y for travel during solar maximum, and 50 rem/y for solar minimum, which given a dose of 22-66 rem + VAE, far outside the "reduced by 10fold" level of radiation, but within the old limit. However, there is a big catch: They're not counting Bremsstrahlung radiation, which is the serious threat from GCR!!! In fact, simply shielding from the GCR can actually *increase* your exposure to radiation, because the secondary particles can be more damaging. How this will be dealt with is anyone's guess, but it will easily raise these doses to unsafe levels.

      However, if you consider that to be acceptable (I wouldn't), then we have to look at other kinds of radiation. Solar flares. The expected dose from solar flares is 600 rem, for a total os 670 rem - a completely unacceptable, and essentially fatal dose. You can shield relatively effectively against solar flares, but to shield the whole craft to a still very damaging 200 rem would increase the spacecraft shield weight to a staggering 38 metric tons. Clearly, this too is unacceptable. Most proposals, now, call for a "storm shelter" concept for dealing with solar flares; the paper's proposal would leave shielding at 27 metric tons; they would have to hide in the cramped shelter for 8 to 13 flares, each lasting for several hours on average. Overall, the astronauts will likely average a couple hundred rem from solar flares.

      It is theoretically possible to somewhat shield from solar flares (unlike GCR) with active shielding, but, like most of Mars Direct itself, this is very unproven technology and a likely source of budget overruns.

Don't pretend that even simple devices behave differently in different situations.

      The rover reports the fossil to Earth where *many* geologist study detailed stereo images, and then redirect the rover bot to take aditional actions, including all those you listed. Astronauts cannot sit and ponder their surroundings for days in order to plan followup, but teams studying photos on Earth *can*. The slowness of a bot is sometimes advantagious that way. The real science comes from sample returns. Even geologists often don't know what they are looking at until the Earth lab takes a look.

      On one of the final Apollo missions a geologist astronaut was enamored by orange-tinted soil and took precious time to dig and collect samples. Although it was interesting to look at, it was not that great of a discovery once analyzed back on Earth. And, remote bots can collect curious samples for return just the same.

      To put robots like you suggest onto mars will require resources like you'd use
      to put humans there.


      No! Life support and human safety issues jack the price waaaaay up. Those pro-human studies you reference are biased. I read some of the Apollo transcripts, and there are a lot of little things that slow one down.

      "More power" means more weight. If you go solar, then your rover gets to be
      bigger and bigger to support the structure of the panels as it moves about.
      This means much higher launch needs and costs, for decreasing gains.


      Supporting humans aint cheap on power either.

      The trap you fall into here is assuming a human will operate just like a
      roborover. A human would set the analysis going and then procede to carry out
      additional tasks, research, and exploration. A roborover, being limited in
      power and designed capabilites, as well as AI, will largely be single-minded.


      That is false. The rovers often did imaging while running spectragraph readings.

      Further, the rovers can "see" things that human eyes cannot. They can see a dozen or so different "colors" while humans can only see 3 (and probably more on a fancier bot). I realize that there are some things that humans do better than remote rovers, but its also visa versa.

      With a manned expedition, we will be producing fuel from martian resources,

      Not on the first missions. It would take far more study of Mars before we know how feasible that is. Nobody is going to risk life support on un-tried Mars resource extraction techniques.

      Further, 20 robots may be conservative. I was generally considering 20 high-end robots, but maybe 50 lower-end bots may be the way to go. A better approach may be to first send a bunch of small nimble survey bots, and then follow up with slower but more thorough lab bots once the data is studied.

      If a human falls over, he can usually get back up. If one of
      the roborovers tips itself over while climbing a crater wall its screwed.

On flat land, such as where Opportunity landed, a rover could cruise around relatively fast also (although Oppy in particular was not built for speed).


      Actually, it is very realistic. It's even conservative. Martian produced methane/oxygene (or even ethylene/oxygen), or methane powered internal combustion engines provide a lot more oomph for the pound than electrically driven rovers. The moon posessed no on site resources such as are used for the MD and MH plans. With this added size and power avaialble, larger wheels with more "offroad" suspension designed for cruising rocky areas is a viable means of transportation. The mars Society has had ongoing research and experimentation with rovers designed for this purpose. Indeed, the 38% gravity is aboon to getting up and over rocky outcroppings when compared to existing capabilities on Earth.

      Given a maximum effective speed of a 1000Kg rover fully loaded of 15Km/hour the daylight only range of a pressurized rover is approximately 180Km. 15Km/hour over rough terrain is well within our capabilities. That's just under 10 MPH. As someone who has done a lot of off-roading 10MPH is not difficult to acheive as an average. It *might* be for a current navigation AI/robot combination but not in a human operated rover. For reference, human wallking speed on earth is about 3-5Mph average IIRC.

      And ina rocky area a human will navigate it faster and with more success and leeway than our current robotic technology allows. Maybe someday (I hope), but not in the near future barring unexpected breakthroughs.

      A roborover, being limited in
      power and designed capabilites, as well as AI, will largely be single-minded.

      That is false. The rovers often did imaging while running spectragraph readings.


      No, I said "largely", and your example proved me correct. A human can do more than imaging while spectragraph readings are going on. he or she could be doing digging, land assessment, route planning, imaging, chemical composition testing, and so on. Indeed, a human can run several of these at a time. We know, we do it today here on Earth.

      Regarding "sight", sure robots can "see" additional colors and so on. But so can a human using the equipment. Only it doesn't need to be integrated into a robotic mechanism. it's not like we'll be sending humans w/o equipment here, for crying out loud. "Sorry Joe but only what your eyes tell you". Nope, not happening.

      Not on the first missions. It would take far more study of Mars before we know how feasible that is. Nobody is going to risk life support on un-tried Mars resource extraction techniques.


      You really need to get out more, so to speak. We've demonstrated the technology over a decade ago, and even refined it. It's gas era chemistry, man. Taking a hydrogen feedstock and using the Sabatier reaction (from the 1800's), we extract and mix with martian atmosphere (primarily the CO2 of which it is loaded) to produce methane, CO, ocygen and water. It's a simple and proven process. Many of the mechanisms have been in use by English, American, and Russian navies for a very long time.

It turns out that dust has accumulated less on Spirit than expected, that the dust on Opportunity was luckily mostly blown off by wind (but since them another dust storm has deposited some new dust on it), and the winter wasn't as cold as calculated -- which means the rovers had enough power, which means they didn't get cold enough for other parts to fail, which means they get to keep operating.

Rover Sojourner could only move with direct sunlight shining on it's solar panels. Did not have rechargable battery packs. Once the power was all used up, the mission was over.

      Spirit/Opertunity: Two rover's sent for redunantcy, and to provide coverage for two different land sites. Rovers have rechargable batteries, and radio isotope heaters to keep the electronics from freezing during the cold mars nights/winter. These heaters also mean the rover doesn't have to use battery power to provide this heat, so it greatly reduces battery load, and extends the mission. The heaters use plutonium-238 with a half life of 27.1 years. http://www.lanl.gov/orgs/pa/newsbulletin/2004/02/0 9/text02.shtml The mars envirornment is dumping a lot less dust onto the solar cells than was esitmated.
