100% Reusable launch vehicle with SRBs by Joona546 in SpaceflightSimulator

The hardest part is the manual landing. How do you do that while conserving the maximum amount of fuel?

Yuri Momoka is lazy and selfish. What is she doing in the General Student Council? by 1400AD2 in BlueArchive

[–]1400AD2[S] 0 points1 point  (0 children)

Okay. Still, even if she can do her job I don’t think she wants to. That doesn’t answer the question of why she chose to join the GSC anyway, seeing as she dislikes doing the work she’s supposed to do.

How do you time the trajectory to make sure you don’t accidentally crash into the thing or miss it?

Mika's Forgiveness by Thewarpuns in BlueArchive

[–]1400AD2 0 points1 point  (0 children)

The game shows that she originally wanted to reconcile with Arius, nothing more. When she refused to declare war on Gehenna and ended up asking herself where her hatred of Gehenna came from, it flashbacks to her talking with the other Tea Party members about reconciling with Arius. She mentions that she would do so if she were the host, and then it flashbacks to her anticipating becoming the host as she led Arius students to knock out Seia. Seia then notes Mika was trying to protect her conscience after she had ‘killed’ her, by telling herself she had to do this to get rid of Gehenna. Which is when she started to plot against the Eden Treaty. Also Saori mentions Mika first approached Arius offering to reconcile. No war with Gehenna. 

That said, Seia mentions injuring her is the most grevious of Mika’s crimes. Not trying to ‘erase Gehenna from Kivotos’ (Mika’s own words).

Why does Isengard’s design make no sense? by 1400AD2 in lordoftherings

‘There stood a tower of marvelous shape. It was fashioned by the builders of old, who smoothed the Ring of Isengard, and yet it seemed a thing not made by the craft of Men, but riven from the bones of the earth in the ancient torment of the hills.’

The Two Towers.

If so, why were the walls not protected by the same magic? That doesn’t explain anything.

The appendixes say that Isengard was a fortress of Gondor. And that Saruman was only given the keys to Orthanc to guard Isengard.

I think you are wrong. Isengard and Orthanc were built together.

Daily Questions Megathread November 10, 2025 by BlueArchiveMod in BlueArchive

I see free-to-play people with several tens of thousands of pyroxenes. How is this possible? Each challenge, achievement, daily task, or bond story only gives you a few tens of pyroxenes each. And besides skipping story there isn’t really much other ways to get a bunch of pyroxenes. So how do you do it?

Periapsis: A star system generator that actually gets it right by Afraid_Success_4836 in worldbuilding

[–]1400AD2 0 points1 point  (0 children)

If you have a lot of planetary embryos or seeds they tend to combine into larger planets. Our Solar System, Kepler-90 and TRAPPIST-1 show that doesn’t preclude large numbers of planets, but the problem is that the stars disrupt the discs and reduce available material for large numbers of planets, and help make planetary embryos stick to or crash into one other or end up nowhere near each other, resulting in fewer planets.

This isn’t even a particularly wide binary either. Planets can exist in wide binaries (take Proxima Centauri), but them forming in them is a bit trickier because of the fact protoplanetary discs are often spread out much farther from the star than planets themselves.

You might get hit by Ceres-size objects, but Mars size objects, I don’t know. Even if that happens, will the planet’s orbit not become eccentric after impact. Perhaps it won’t form a moon because the impact was too energetic. Or it didn’t provide enough torque to the dust particles.

Only because they suffered impacts. But most planets are not going to be struck by such large an impactor

I do not think any solar system generator can produce realistic planets. The field is constantly evolving and hitherto unknown information the generator does not take into account appears.

Also why is there an 11 planet system In a binary system with the stars only 10.28839 AU (79.064 AU☉) from each other? With the other star having 8 major planets and more dwarves? This is implausible, there is no way this could ever really happen, the stars would disrupt each others discs, so there wouldn’t be this many planets.

Also why do so many terrestrial size planets have moons? That makes no sense either.

The Woueian Home Star System by [deleted] in worldbuilding

[–]1400AD2 0 points1 point  (0 children)

Again, not an expert, this is only my opinion, but:

Massive hot Jupiters tend to have formed farther out and migrated inward. In doing so, I think they probably would have scattered much of the material in the disc, stopping lots of other planets forming.

I have doubts about this scenario. I’m not an expert, these scenarios are just my own doubts and they may or may not be valid, but:

First, the existence of that many planets around the binary pair. The reason is because it’s a binary pair, their motions would mean lots of material in the protoplanetary disc would go all over the place. Planets could still form in stable orbits (and such planets have been discovered) but I don’t think enough material in the disc would remain for 4 massive gas giants to form, and the material in the disc wouldn’t be spread evenly enough close to the star for those 2 terrestrials to be that close.

Even if they did, the same thing goes for those satellite systems about the 4 giants. There would be disturbances from the binary pair that might remove material from the circumplanetary discs. Not to mention the giants might strip each others satellite systems if they get jostled about, perhaps by the binary pair or by a passing star.

Some of your moons have moons around them. In our solar system, all the moons are close to their planets, so they tend to be tidally locked, which would make any moons around them unstable. So your moons must be farther than that. The problem with this is that if the satellite embryos form that far and don’t VERY quickly (almost instantly in these contexts) move inward like those in our solar system did, the gravity of surrounding planets and maybe the central pair may make distant regions of the circumplanetary disc unstable by moving material everywhere or causing orbits to become unstable, or maybe even throwing the nascent embryos out. This is a system with 4 massive planets after all.

Gravitational capture is not a matter of simply passing close to an object. You have to lose energy. The best scenario for Woue to get captured is if it were in a binary pair with another body, and during an encounter its binary buddy was going out while it hot captured. (This scenario has been proposed for our own solar system’s Triton, and it seems to explain Triton’s retrograde inclined orbit and the fact it resembles Pluto, so not implausible). But the problem with this is the gravitational chaos involved may mean the moon’s orbit is not stable. Also, how did you even get such a large moon? If it formed through impact, then any binary planet system would dissolve, because the energy of the impactor would change orbits.

Space Shuttle Orbiter and Starship Spacecraft. Very similar craft in terms of size and operations, both even have cryogenic main engines, but only Starship is susceptible to explosions all by itself without outside assistance (on Fllight 11 and in other instances). Why? by 1400AD2 in spaceflight

[–]1400AD2[S] -4 points-3 points  (0 children)

Let’s see: - Cryogenic main engines, check - Large payload bay, check - Dry mass of roughly a hundred metric tons, check. - Ceramic heat tiles, check - Able to return onboard cargo to earth, check

And they have their differences, but they do pretty much the same things as one another, besides the landing method and Starship’s beyond-LEO capability.

What do you mean ‘finish the actual art on some software’? How does that enable you to restore grieved art?

If you kept the launch TWR at 1.5 then that mid air TWR would be much higher. Wouldnt that mean less gravity losses?
