Yes, if you include the L1 and L2, can not imagine Web uses it. And then I talked about communication lasers in space they would be in earth orbit.

I was thinking about that comic then writing the above

For some reason drawing an line between two points always give an straight line if using an ruler I would expect it to be couple of % variation because of weather on the large star.

I see two things here, the supernova and the nebula. Chinese documented the supernova, did the Islamic and Japanese describe an nebula or an supernova. Europeans was late and might only discover it after telescopes? And the Chinese source sound a bit weird, more of an over the top action movie. But why is it tragic is used for calibration, except that the nebula would expand.

An reusable NTR rocket has two main problem, first is radiation after use it would make servicing it very hard. People was thinking of nuclear powered planes during the cold war. You could shield the crew of an bomber but not all around. Same issue with an rocket on ground. Second is accidents an failed landing will be an nasty mess at the best case.

I see the problem as way larger in less hard sciences like physiology or economic, here dogma can establish and thrive, health is the larges arena for pseudoscience with anything from overblown trends to homeopathy who makes no sense at all. And in technology, why do people try to design SSTO? Only way it makes sense today is to fool investors with cool technology. But it has been so many designs who has been actively worked on.

Might be an lack of benefit of large scale organization. River valleys and deltas was civilization starters as large scale irrigation infrastructure paid off big time. Writing is also important if you get large enough or the power structure become less stable. Now with better technology you will get large scale benefit because of it but this would be closer to industrialization even if Romans and Chinese benefited from it like rapidly raising armies of well equipped forces. Rome kept building fleets until they won the Punic wars.

Except it was not the Europeans who drove San off their original land, it was other Africans before European colonization, farmers and herders displaced them. European then repeated the process again against Africans to some degree. And they probably knew that you should not over hunt an area for small games or dig up all the plants in it but the huge migratory herds was another thing. its very likely say ice age hunter gatherer was much less nomadic than more modern ones like San who are restricted to areas not suited for farming. And its population density dependent after all the diseases in America killed off most of the population after Europeans arrived many people in North America switched to hunter gatherers as it was room for it and its less work. Farming in America was also more an pain because no good draft animals and less efficient crops than Eurasia.

No idea but the viking had apples even found as grave goods. Imagine this worked out might be that the attitude an location was not good for apples, pretty close to the tree limit so they only knew them from trade. Then you had the priests advocating for potatoes to farmers and they might become know as apples locally.,

Agree, its weird. and its not like potatoes is new either.

As an Norwegian I agree about these, and Analius was not uncommon 100 years ago. Just having æøå in your name was an hassle, probably less now today with unicode. You still have stuff who translates poorly, either to bad worlds or to negative words like slow or unreliable. And dialects, my favorite one was visiting the mountainous areas of central Norway there my mother had an friend. Serving some meatballs and I was asked if I wanted apples, I said I take them after the meal. But in their dialect apple was potato and sweet apple was apple. Literally translated.

I would not call it weak, it has to support upper stage trough maxQ including bending forces. But it faces two thermal shocks, first is separation, after upper stage goes to full trust its not longer required to be structural, it then faces the heating during reentry from an suborbital trajectory. Yes the protective cover over the top of first stage take more of an pounding during separation is not structural, just to protect first stage an be an weather covering for the top systems at other times. But, down the line they will want to reuse it. My guess is that they will make it more of pipes like the Russian hot staging segment as easier to protect or cool but they will anyway have extra drag on the top, but it might be so different the current design does not matter?

This, now I kind of suspect future missions will move more over to use lasers as the bandwidth intense links, suspect lasers will also be better at long distance communication. But this pretty much require receivers in space or bad weather can block you off. But you probably just need one satellite looking at mars to receive the signals from multiple probes there same for other planets.

Did flight 2 jettison the hot stage ring? Yes it add drag to the top, but any simulated landing would be useless without is as it will be present on later landings and catch attempt.

An obvious good idea if you had the launch numbers. You need to launch 100 times for it making sense. It also has to be cheap, not like the space shuttle.

One option might be an dock and boost, perhaps leaving an small independent module with secondary retraction wheels to take the load off the primary ones. Had an idea for an shuttle mod for starship, as in smaller crew space, larger cargo bay and multiple arms, designed for repairs, upgrades and recovery of satellites out to earths L points.

Just watched this and the caption at 13:43 makes it. Now this is an real thing Soviet got to the nuke fast because they know it works and had lots of spies. Now it was one sci-fi short then they rebuild after an catastrophe, captain held an speech saying they was up to the ancestors tech level and then activate warp drive

Wealth inequality is heavy screwed by tax rules, its often an benefit to have debt for tax reasons so you buy apartments and rent out in Switzerland and lots of places in Europe. Norwegians started to get an breeding season because of kindergarten entry rules but birth wards was not set up for this. And the obvious Freefall reference http://freefall.purrsia.com/ff2900/fc02843.htm

As I understand one chute is backup, landing will be rougher but fine if one fails. Reason to have 3-4 of them

Just like night landings on carriers is routine today.

Hint: Larger spiders are easier to milk

Agree, one crazy part about aircraft carrier landing is that you go full throttle on touchdown. That is so you can take off if you miss all the hooks. More crazy back during WW 2 and before angled flight deck you often had planes parked on the front part of the deck so if you miss the hooks you will crash into them. Granted propeller planes landed much slower but still. US operated two training aircraft carriers on the great lakes, they used paddle wheel and was coal fired It was cut down passenger / party / cruise ships like many ferries in Europe is today used for training carrier landings.

My thought too, placing is done remotely or perhaps at site lining up things and shipyards had far more powerful cranes 50 years ago. Catching will be automated.

Worse case they are using the time from calling out firing to they leaving to do the patch and perhaps an rushed colony update. Often companies pay out and fire people at once so they don't do damage, but don't think is an issue here as they have current version.

Well we will live an world of fully reusable heavy lift soon. Not that this technology is pointless but more on staying over an area for long times The drag would be the killer here I say, low trust work in space not in atmosphere.
