    What happens when a human is not sure of what to do and he/she needs to wait for orders from earth, or earth needs to wait for the humans on mars to send data back to them.

    You don't have it as often. Both humans and moderately advanced robotics can find things to do while they wait too.

    Yes humans are just an expensive payload, but why use them when there are more cost effective payload options?

    Currently, there aren't.

    Humans have basically hit their computational limit.

    It's not a computational problem and we're nowhere near any such limits of humans. Basically, we have at most a few weeks of Mars surface work and research for humans spread out over four decades.

    You still have the fundamental problem of control and communication. Mars can be up to a light hour away and the outer Solar System is even worse. That's terrible when you're trying to operate machinery remotely and it also shows up in large delays when making any decisions about the activity in question.

    Further, you need to deliver that computer to the destination and it'll need tools for doing its job. Those things aren't govern by Moore's law. For example, there's a certain minimal amount of infrastructure one needs in order to return a kilogram of rock to Earth or drill a few hundred meters into soil. Radiation hardening also creates a scale limitation. Make it too small then it breaks when it gets zapped by charged particles.

    Humans are just another payload. While humans have quirks that make them somewhat more expensive than most payloads, computer/robotics systems will have many of these same quirks (such as sensitivity to radiation, need for a controlled environment, the need for resources such as energy and management of those resources, etc).

    I think my comments kind of weren't your point. For example, you're babbling about "condone violence against 'innocents'" on the basis that someone just fought a war and thought they might need to again.

    We do have many historical examples of violence against innocents, including a few from the US's Revolutionary War. But most war is not of that sort. It's violence that involves innocents, but it doesn't target them. For if it did, there'd be a lot more dead innocents than there have been.

    My point is that I'm saddened that we will fight so hard to keep open the violent guns part of the constitution, but keep rolling over on the trampling of other amendments in the name of security.

    While some people don't place the same importance on every bit of the Bill of Rights or the Constitution, it's worth noting here that people who tend to advocate violating the Second Amendment, tend to advocate breaking other amendments as well. My view is that there's nothing magical about the wording of the Second Amendment (that people had a right to bear arms). Anyone who can misinterpret that bit of law to their own advantage, can do the same for any other bit, such as the vaunted First Amendment.

    One man alone can't rebel against any tyranny.

    Sure, they can. It just means that they're very unlikely to fully succeed. But it is quite possible, for example, to cause far more damage than you can possibly receive. For example, we have two cases in recent years, the 9/11 attacks (which led to all these terrorism responses which you complain about) and the self-immolation death that triggered the Arab Spring (and the downfall of four governments so far). That latter case also didn't start with much in the way of organization. The guy in question apparently made a threat that he would burn himself, then he did it within the hour.

    But that event was enough to knock Tunisia into an uncontrolled state with escalating riots that led within the month to the flight of the long time ruler of Tunisia to whoever would take him. It then spilled over into the rest of the Middle East and North Africa, taking down the governments of Egypt, Libya, and Yemen as well as triggering a nasty civil war in Syria.

    Did the founding fathers really deal with or consider single perpetrator mass shootings? The closest thing I could think of would be bombings, and I don't know that the Second Amendment had anything in there about explosives.

    They would have been aware of Guy Fawkes and the attempted bombing of the UK Parliament. And it's worth noting here that single perpetrator mass shootings don't actually kill that many people - especially when the would-be victims happen to be armed.

    Of course, if we were that OK with the level of death, we shouldn't be anywhere near as freaked out about terrorism as we seem to be.

    Well, I'm not particularly "freaked out", though I should note that the US has lost about as many people to the 911 terrorist attacks as to single perpetrator mass shootings.

    Higher cost is a different argument. There we need to keep in mind that access to space is getting cheaper over time. It's a lot less expensive to do things in space now than it was in the 1970s.

    That dynamic will change the relative costs of a manned mission versus unmanned missions. And given that the former do orders of magnitude more than the latter currently, we need to consider that the price can decline to the point where purely robotic missions no longer makes economic sense.

    There is an implicit contract between all of us on how society works: that we give up some freedoms, as do our fellow citizens, in order to make society work.

    I'm willing to call it a "cooperation". A "contract" implies things that don't exist here such as explicit terms and agreement to those terms.

    The fact that it is not written down means that we can actually have different views of what is actually in the contract

    Well, as long as we all agree on what that is, that's ok. Else this unwritten contract isn't worth the paper it's written on.

    Writing things down fixes them, while society changes.

    So what? There's no indication here that the cooperative aspects of our society changes. For example, the concerns of privacy haven't changed despite the changes in technology.

    A prime example here is the Second Amendment: while not saying it is right or wrong, I am certain those who wrote and passed it did not foresee current firearms technology.

    I think that's a dubious claim to make. All that has happened is that such firearms have become lighter, more reliable, and have a much faster firing rate. In other words, they've become better at the job they do. That's not hard to predict. And I'm fairly certain that the technology hasn't advanced to the point where original backers would have changed their minds.

    People say that a lot for this sort of thing, but I don't think it's been done, except for the ISS. When Apollo was setup, just rendezvous of two different things was considered potentially impossible. Plus, what's the real advantage to this assemble in pieces, except for getting around the maximum lift capacity of modern rockets?

    Aside from that very important thing of not requiring a huge, expensive rocket, it also reduces the risks from a launch failure. There's nothing on a spaceship, including its crew, that you can't have back ups of.

    Second, there's nothing magical about assembling things in orbit. The ISS, for example, didn't have a particularly difficult time of it. And docking spacecraft with each other is becoming rather routine. That's another route to assembling things in orbit.

    I maintain that LEO is 100 km... average distance to Jupiter is 8 million times further. 8 million

    And I noted how irrelevant that observation is. You can just drift and all. I think it more significant, the time duration of the flight. Even with considerable propulsion power at their disposal, say nuclear propulsion, it's still a long trip. I can't see it becoming less than two years one way (Hohmann transfer trajectory with Jupiter is 2.75 years, you can hustle that a bit with better propulsion) without a substantial revolution in relatively affordable propulsion.

    Have you seen the rockets built for voyager?

    Launch the pieces of the vehicle and its propellant via rockets used today into LEO and assemble. Solar-electric propulsion with aerocapture maneuvers using Jupiter's atmosphere would work. I think the bigger problem would be coming up with the funding and a means to try out the technology. That is currently many orders of magnitude.

    That 45-second figure on Mars sounds hyperbolic, since on good days, the rovers can actually go pretty far and take lots of pictures.

    And on bad days, nothing happens, meaing it takes 0 seconds to do what was done. I think a good comparison here is between the Mars rovers and the corresponding manned lunar rovers of the Apollo program. They travel about the same distance. Apollo 17, for example, had three excursions of the lunar rover, each a bit over seven hours, for a total of somewhere around 22 hours of time on the Moon, the longest set of the Apollo program. They covered almost 36 km of distance over that time. The MER rover, Opportunity traveled a bit more than that over almost ten years.

    So say about nine years to travel what the lunar rover did in 22 hours. Divide 22 hours by 9*365 and you get almost 25 seconds. I imagine the longer time of 45 seconds is because of the somewhat faster speeds of the MSL rover.

    As to the scientific value of each, it's worth noting that the lunar missions were sample return with a considerable quantity of material returned. Any scientific comparison is going to strongly favor a sample return mission over missions that don't have sample return just because of the much higher value of returning samples for study on Earth.

    Anyway, I'm all for space exploration, but people do not seem to understand how many orders of magnitude there are in distance between low-earth orbit (which is becoming routine, but still not "easy") and a moon of a planet that is halfway across the Solar system.

    Those orders of magnitude of distance aren't particularly relevant. For example, the ISS travels at roughly 7.7 km/s relative to Earth. That's roughly 1.6 AU of distance every year. Europa averages 4.2 AU away. We can travel distances considerably longer than Europa in a human lifetime at velocities achievable in low Earth orbit.

    As I see, the open and public process is not in the creation of the report. As to the IPCC "summarizing" the "peer-reviewed literature", it's worth noting that the IPCC is first and foremost a political tool for justifying a variety of public spending themed around renewable energy and carbon dioxide reduction, such as renewable energy subsidies, carbon credit markets, wealth transfers from developed world to Third World, and public transportation. So any "summarizing" the IPCC will do will be oriented towards supporting such public spending. That is the nature of propaganda. Keep in mind that a large part of the "peer-reviewed literature" is also propaganda.
