It was an 19th century stupid idea to introduce hippos to the Mississippi river. It folded because cost and they could not monetize it also an question if meat would sell.

You don't with this technology. You might take some incredibly photos passing the lens point photos who show far more than an pale blue dot.

And the header tanks give some very interesting abort option that it unless you drain it all into the feeders for touchdown or catch, might end up with an more complex system. The obvious most dangerous part of an SS mission is the flip and land not liftoff. See an escape system for SS more as an escape pod as in ejecting the cockpit on an bomber not an true space capsule. For cargo missions you would starting bringing stuff back who require flexibility for down mass.

Starship main issue is that its heavy, 150 ton dry mass I think, its two space shuttles. Now the cargo capacity is up to 10x heavier than the shuttle. I say for higher orbits like GEO having an reusable tug inside SS getting an satellite into GEO and then back to LEO and dock with an second SS makes sense. Disposable for cargo missions to moon and mars there the ship is raw materials or makeshift modules for storage or farming. For stuff like Europa sample return or Pluto orbiter / lander, 3rd stage with balloon tanks and an single raptor 3rd stage. Put SS in LEO, refuel it and 3rd stage. SS burn to raise Ap, note that 3rd stage is 500 ton now. Release and return SS to base. 3rd stage extend solar sail and wait until capture burn.

Newtonian gravity works well enough outside of Mercury and even there its just an accumulating error. KSP with just one gravity source adds more errors, most noticeable is that Jool might interact with an craft going to Duna or Dress if outside and distort the trajectory. Now for players this would looks like an bug unless its calculated into the trajectory preview.

One option at least down the line then you want to reuse the deep space tankers, either for transporting fuel to moon orbit or then tanking up fleets for mars. In the start I guess they use sunshade and / or foam insulation. An inflatable sunshade does not disable return to earth if you an drop it and land. For going to mars one option is header tanks inside the main tanks who you keep in vacuum during transit.

The header tanks has pretty low surface area compared to the feeders. Now as you say they could fill the gap with liquid for launch then drain gap with the tanks, in orbit probably pump out rest liquid from tanks to top off header tanks. Probably during end of burn to orbit and / or deobit burn. Then went gap to space. I say it depend on the size of the gap between feeder and insulating wall. Header tanks has contact with outs skin including heat tiles so having double walls here makes lots of sense, the feeders are inside the tanks who will contain pressurized gas for integrity but less heating? Also the block 2 design has some weird stuff like the extra feeders for methane to the vacuum engines. any liquid in them is wasted after reaching orbit and you don't want free flowing liquid in the tank anyway so I assume methane feeder from header going down to the common bulkhead.

3 GHz is 10 cm wavelength or why few stuff outside of chips works on the GHz range. Now that light speed is an major limit inside an box you can have on your desk is mindbogglingly in it self.

In mud this one would use sonar. Khajiit think you sound Argonian.

My bad yes its X^2 as the power of point source at distance. And don't think its an major difference between redshift and doppler shift outside using red shift to estimate distance. Doppler shift of radar signals was used back in WW 2 to mask out static or slow moving target for air defense radars.

Stars and planets would work well enough for the timekeeping, Now the planetary axis might be much more unstable. Not sure about the effect but assume more radical climate changes

Inverse square or rather cube x^3 affect any point source like a star, double the distance and its 6x dimmer. 10 times the distance and its 1000 times dimmer. Red shift is unrelated, think sounds of an train or ambulance passing you. Or you moving away from sound who it probably more of an bomber crew sound.

I don't think so as the gravity gradient is so weak outside of the black hole in the center. Earth gravity is not uniform, Starlink and probably others uses this to change inclination. Moon is so lumpy, I assume because all the metallic asteroids hitting it (mining locations) so low orbits are not stable. Its couple of degree at worse so you watch an string with an weight at noon and it visible don't point down.

Universe expanding don't affect local stuff like galaxies or even gravitational bound clusters of them. If it affected local stuff it would include stars who would get dimmer as pressure in core went down and we know ancient supernovas work as expected Example earth curvature is so large it only affect long ranges, laser or microwave towers, artillery fire and sniper rifle shooting at an km or more, making 20 km long tunnels but you want the center to be higher anyway for drainage. Initially it was just useful for navigation,

LOL, thinking of putting an clapper inside the bell

I think its a bit weird they has not started on this long ago. Not even sure how far you are from places you can get multiple trailers a day of oxygen and nitrogen. Methane is also an issue as you need refined LNG who is kind of an special product but they get it and its just an faction of the trailers.

My university in Norway had something like this less fancy but more advanced I say as it was closed, it was an group of office blocks, they build in the area between them. Now they had an nice common area and the heating bill went down quite a bit too. Strip malls has some issues over regular malls in Norway during winter. Also some places glass over back yards in city blocks.

SpaceX also launched an very tiny payload once, think it was contracted for Falcon 1 but got delayed, and it was an mission suitable for ride shares. BO is an first test flight who usually fly with just an dummy payload, instead they fly with an tiny internal one, gives more fuel for landing fist stage.

Yes was thinking this, its not something I think works well for producing concentrated ammonia for fertilizer pellets but something added to integration or perhaps using an tank trailer with an sprayer a bit like how liquid manure is used. Well its smell better

The talked about generator is the nitrogen source. My issue is the the water has little ammonia in it so hard to use to make fertilizer to sell but if used to add nitrogen to the water on the farm this is less of an problem.

yes now an fan don't use much power and refrigerators are very inefficient compared to more efficient ways. It depend on the cost of the catalyst. Now the ammonia concentration is low. Is recycling vaporizing the water with ammonia and running it trough the catalyst multiple times? one moll of ammonia is just 17 gram. Now this might be low tech enough that you can just have this on a farm and add this to the irrigated water, in this case the low concentration is not an issue. Or if its an easy way to get it out of the water?

How much would the dome realistic reduce it with, And in that case its not viable I say, outside of stuff like restaurants could do it here you could use much heavier domes as they are much smaller, more the size of the above tent.

This, you can do reproducible science on magic systems in video games. This might even be done before game is releases. Elder Scroll 3 Morrowind had an alchemy system who let you boost all your attributes like intelligence, raising intelligence increases your potion strength so you can make better fortify intelligence potions. Its no limits outside the 2^31 or two billion for signed integers. People pointed this out before launch. And it worked as expected at release. an billion in intelligence, then raise wisdom, you could now make any spell, this would be expensive luckily your potions sold for 100x the money any merchant had. Do not boost speed by potions or make levitation potions you will have to wait weeks real time for them to wear off. Now this is even more important in online game, called metagaming and very common in MMO and PvP games. Many creators here has been rightfully been criticized for assuming flawless groups or that Pvp between groups of unkillable tanks is very boring.

The thing who stuck me was no balcony, here in Norway all city blocks have them, exception is the old ones downtown and this is Norway where you will use it for 1/3 of the year. My block is 50 years old and it had them enlarged. Looking at modern cruise ships I say this is an trend.

This now BO has picked up their pace a lot. Even and this is an joke: They messed up the paperwork to FFA on purpose to get an reason a delay they can not be blamed on, and it would not be that many months delay.
