  1. Re:Huh on Comet Probe Philae To Deploy Drill As Battery Life Wanes · · Score: 4, Informative

    "It seems to me the design and/or planning of this mission were poorly thought out"

    Jesus-Dunning-Kruger-Christ.

    And Philae bounced twice, finally settling in two hours after first touching the comet, which is enough time for the comet to rotate almost 60 degrees. The two systems meant to prevent bouncing - the thruster and the harpoons - failed, so it ended up some kilometer away from the carefully chosen site. That we are getting any science at all after that potentially mission-killing news is just fantastic.

    I'm hoping they make some last-ditch effort to have Philae try to jump over to another part of the comet to get more sunlight, though I'm not sure what kind of resources they have to try it. Can they command the drill and/or the legs to jab downward relatively quickly? Command the harpoons to fire? I don't know, but you can bet this will be part of the design on future missions. I actually did some work on this, which made hopping around a key part of the mission.

    My statement was that we will tailor ourselves through a mixture of technology and biology.

    If we were actually committed to the technology, we would never have to go ourselves. Sending human bodies implies a zealous commitment to a low tech solution frozen in time, like steam power in the age of electric cars. If we had the technology to make Mars comfortable we would have no need to do so, since martian robots will outstrip the utility of the human body by a country light year.

    This is not quite correct, because robots don't have brains, and that is unlikely to change in the near future.

    Some parts of our bodies are easier to replace than others. We have been replacing skin, blood, and bone (albeit imperfectly) for a long time. We are becoming better and better at replacing or removing parts of organs like kidneys, lungs, and even the heart. We are not even close to doing the same with our brains. We are starting to learn to do some awesome stuff with it, like control other people's limbs, and we may have even found the on-off switch for consciousness, but we can't replicate or replace the brain. We tried removing parts of it before, but even ignoring the horrid ethical violations, lobotomies had disastrous results and are no longer practiced.

    Anyway, the point is, yes, robots could (and will) be a very significant part of colonization effort, but they can't replace humans entirely. I'll give you the idea that much of the human body is low tech, but our brains, though far from perfect, are more advanced than anything we've got.

    Infrastructure is a lot more complicated some pressure capsules and solar panels. Infrastructure to make a colony viable would mean agriculture and industry (including ways to deal with their negative externalities). Everything about both of those would need to be bootstrapped from Earth.

    Even at SpaceX's best rates for the Falcon 9 and Dragon capsules at maximum capacity it would take over 14,000 launches to put those 100,000 colonists into orbit. That alone would cost a trillion dollars (assuming awesome rates from SpaceX and no failures). Just the structures and resources to keep those people alive for the first year would cost several tens of trillions of dollars more. The infrastructure to make an actual colony...well hopefully you get the picture. To put the numbers in better perspective we've only launched a little over 300 manned orbital missions in history. Ever.

    A solid outline of the challenges, but a simplistic understanding of the proposed solutions. You don't put 100,000 colonists in orbit as fast as possible and put them to work building a metropolis on Mars. You put a few fertile and healthy couples on Mars at a time, over and over, and you grow the colony over hundreds of years. In fact, you grow several independent ones simultaneously, so one can evacuate to others in the event of an emergency. An additional 300 launches spread out over, say, six Earth-Mars launch windows (about 10 years) could mean 1200-1800 colonists, not counting any children they may have, and the infrastructure, agriculture, and industry involved in supporting those people would grow with the population. It would be heavily reliant on Earth for a long time, but that reliance could slowly disappear over time as Martian humans make do with what they can produce themselves, which could end up being a lot more than we can imagine with today's technology.

    Of course, also on those timescales (centuries), the ability to recolonize Earth is questionable. Even the first human that grows up on Mars would have a great deal of trouble adapting to Earth, which would have three times his or her native gravity! They could probably do it with some fancy exoskeleton technology that might not exist yet, but their bones wouldn't be used to the stress at all, and they could easily have some crippling agoraphobia. But who knows what other adaptations the human body will undergo, given enough time. If anything, colonizing Mars is a stepping stone to a mostly space-faring civilization, but that's far, far into the future.

    This impacts Drake equation and might shed light as to why we have not detected any other sentient life in the universe.

    No, it does not impact the Drake equation at all. The drake equation is based on R* and f(p) which are the the "rate of star formation" and the "fraction of those stars that have planets" (from your link on wikipedia). Both of these numbers are not affected by this finding.

    Really it doesn't matter much since proposed numbers for the various factors vary so wildly, but it could change the Drake equation if you wanted (there are other factors listed on the Wikipedia page that could change it as well). In this case, the first three multipliers, R* x fp x ne, estimate the rate at which habitable planets form, but since those terms focus entirely on planets around stars, it ignores habitable homeless planets. So you might replace that with (R* x fp x ne + Rh x fhh), where Rh = rate at which homeless planets form, and fhh = fraction of homeless planets that are habitable. Granted, fhh is probably extremely small (civilization would have to develop deep underground near a molten core), but if we can imagine it, we can't rule it out. There's a bit of a weird crossover when it comes to planets that are flung from other systems (e.g. if it was too close to its star to be habitable, but now its in near-absolute zero interstellar space...), but I'm ignoring that for now. It's all just interesting conjecture anyway.

    Where in the US do you live where food is so expensive?

    It's almost certainly the veggies that are the problem. In Colorado, the thinnest state in the nation (though even 1 in 5 adults there are obese), I could get all manner of cheap but high-quality fruits and vegetables all year round from Sprouts (a chain grocery store that calls itself a farmer's market). Bell peppers were almost always on sale for $0.25 - $0.50 apiece, and that's including orange ones, which are generally more expensive. Where I live now, 1 in 3 adults are obese, and I'm lucky to find green bell peppers, which are usually the cheapest, for $1.00 apiece. The parking lot farmer's markets (they also had those in CO, by the way, but prices were rarely better there than at Sprouts) are all over now, and their prices weren't much better anyway, so crappy grocery store produce is once again my only option.

    As a result, we often end up buying frozen veggies, which don't taste nearly as good, so we don't do it as often. We ate a lot more rice and veggie dishes and salads in CO, but we eat more pasta and meat dishes here.

And we're growing lettuce on the ISS using hydroponics right now. And so on.

    Sure, the reality TV funding plan is something of a joke and there are plenty of technological hurdles to overcome, but what's important is that Mars One has a starting point and is apparently paying people to execute it and independent researchers are looking at them seriously, pointing out issues, refining the plan, and suggesting improvements.
