11 Amazing Things NASA's Huge Mars Rover Can Do

TheNextCorner writes "NASA is getting set to launch its next Mars rover this week. The car-size Curiosity rover is the centerpiece of NASA's $2.5 billion Mars Science Laboratory (MSL) mission, slated to blast off Saturday (Nov. 26) from Cape Canaveral Air Force Station in Florida. The rover will employ 10 different science instruments to help it answer questions once it touches down on the Red Planet in August 2012."

My head was just at a place that said landing on the planet was really the only thing that is important right now, AND all the things entailed to achieve said landing. As far as the actual landing this time, it is pretty damned involved. I'm not sure if you are aware, but it isn't a passive decent this time. It does start classically with heat shield and parachute, but then it uses rocket motors to descend further and then hover while it lowers the actual rover to the ground on a winch. And then flies off somewhere once the rover has touched down and the cable(s) is released (probably doesn't matter where the airborne vehicle goes as long as it isn't right on top of the rover). Things as mundane as releasing the cable are worrisome, never mind the uber high tech stuff. So that is why I think I would rather wait till it actually lands and can communicate with home before bragging about the other stuff. If it doesn't land then I think it would be better not to do the 'look at all the cool stuff we could have done dance. So yeah, I get your point. I just wrapped it all up in one phrase.

      There is a wider difference between the rovers current software and a skynet like murder-bot, than there is between our current UAV drones and a skynet like murder-bot.

      The UAV's can do 95% of the hunting down and targeting process all by itself.

      With a malicious reflashing of a UAV drone, the entire killing process can be automated and left on its own.

Software wise yes the difference is huge: but hardware wise, this rover could be weaponized pretty easily.

    If I had say in the matter, I would include more redundance.

    Instead of one of each type of camera on the mast, I would include redundant cameras on each mast.
    Instead of one mast, I would require two masts, with separate motors, computers, etc.

    I would include both mechanical (or pneumatic if compressors that work in that environment can be made compactly enough) and electrostatic lens cleaning mechanisms.

    I would include redundant "legs" and wheels, with the primary set being ejectable in the event of failure.

    The cost would go up, but given that when you come down to it this amounts to a $2.5bil RC car, spending a few million more on extreme redundance to guarantee reliability (after it hopefully lands safely) is very cheap insurance - it's not like you can just send out a minimum-wage Geek Squad "technician" to (hopefully) repair it and upsell it on gold-plated HDMI cables and Norton AntiVirus. ;) It'd suck if the one mast failed, or one "leg" failed without a backup unit or mechanism.

      The problem, of course, is that you end up adding weight with all that redundancy. The added weight makes it more difficult to land, making it less likely the mission will succeed.

      Personally, I'd just build more than one rover. While I can believe that building one cost $2.5 billion, I tend to doubt building a second one would cost another 2.5 billion. And, if everything works as planned, having two rovers wouldn't be a bad thing.

      Why do you suppose it doesn't have redundancy or failback mechanisms? For example, it has SIX wheels. The Spirit rover could still work (and did) with only four wheels. Also, the whole rover is a complex laboratory capable of doing many experiments. If one of them fails, it can still do science with the others. Adding a secondary mast, computer, etc, adds weight besides redundancy.

      In short, they can't without significantly adding to the cost. They are at the limit of what can be shielded using current technology (I'm referring to the heat shield). Any shield larger, needed to protect a larger payload, would cook the payload. There's some ideas on how to make larger heat shields, but they haven't been tested (or even built) yet.

      I don't even know if there's a rocket large enough to carry such a large vehicle to Mars as the one you're proposing.

      Finally, the cost doesn't proportionally go up with extra weight on the vehicle. They go up exponentially. It would probably be cheaper to send two identical vehicles than to send one that weighs twice as much.

      The mission is $2.5bil - and while a good chunk of that is R&D and implementation of the probe itself, the major chunk of it is delivery and also mission control. The cost of building redundance into the probe (and someone asked why not just add more different instruments? The added cost vs. weight for redundance to all instruments is negligible compared to the overall budget, etc. and it would suck if the optical camera dies but everything else lives - because the optical photos are what sell these missions to the taxpayers.

      I do like the idea of building a second rover - the bulk of the cost isn't building the RC car. The bulk of the cost is comprised of delivery and personnel.

      If I had say in the matter, I would include more redundance.

      Unfortunately redundancy means more weight. And less space with less functionality. The limitations on the payload are space, weight, and cost. In comparison the original Mars Viking landers cost about half as this rover and they did far, far less.

      I would include both mechanical (or pneumatic if compressors that work in that environment can be made compactly enough) and electrostatic lens cleaning mechanisms.

      More mechanical moving parts == more points of failure. Eventually moving parts will break down. The Spirit and Opportunity rover lost functionality of their wheels after a few years. As for pneumatic, that is really not feasible. The atmosphere of Mars is less dense than Earth and would require much larger equipment to achieve the same result.. As for electrostatic lens cleaning, the question is how. The solution to cleaning the lens would take away from payload and have minimal effect against the Martian dust.

      The added cost vs. weight for redundance to all instruments is negligible compared to the overall budget

      It costs about $22,000 per kg to reach LEO. For a one-way to Mars, it will be about $154,000 per kg. At 900 kg, the cost of sending just the rover in rocket costs is $125-136M. The other problem is not so much the cost but the practical limitations of launch. You can't send any size or weight you want. There are size and weight restrictions on payload because of limitations on rocket technology. If you want to increase the size of the payload, you have to R&D bigger rockets. NASA is currently using Atlas V as this is one of the largest rockets they can use today. A Saturn V would launch a larger payload but it doesn't exist anymore and in today's dollar, the launch itself would be $1.11B just for the rocket.

      So the choice is either have 10 instruments recording 10 different things or 5 instruments doing5 things and 5 of them not doing anything at all. By the way you have one shot at launching and landing.
