We need all kind of animals up there. 62 fucking years in orbit and we still haven't sent anything. I want to see a macaw just trying to extend its giant wings and fly. I've heard they'll have problems swallowing food or even water as birds just use gravity for that, so we'll have to hand-feed them every single day. Also, I'd love to see a comically large animal in space like a whale or an elephant. Maybe one day, after Starship has long established itself and is sending segments of pretty wide space station in the near future. Or perhaps Starship by itself could do it, but it'd be a dedicated ship without being divided into several stories and modified so that the animal can survive the launch. I hope fucking PETA and others enviros don't start being a nuisance like always.

Russia also has a not-incapable fleet of launch vehicles, and the UAE has expressed interest recently in kickstarting its own semi-domestic launch capabilities. I'd love to see them pitch in funding for the Soyuz-5, but a Soyuz-2 at CSG style deal wouldn't be impossible either.

If Roscosmos is going to have any hope of holding on to what its got it needs to find international partners to replace America and Europe. India and the Arabs are the best and most obvious choices.

Flew an Ariane 5 and Hermes in RSS but instead of solid boosters, it uses Liquid Flyback Boosters.
The design here is based off a legitimate study done in the 90’s about replacing Ariane 5’s solid boosters with reusable liquid ones.

Pic flew pretty well. The ascent is a bit steep but the booster return wasn’t that bad. They have a horrible time with rotation, probably due to their small vertical stabilizers.
Now, IRL, the original Ariane 5 + Hermes plan involved no second stage. In KSP, Ariane actually fell about 1 kilometer per second short of orbit, but Hermes’ giant service module pushed it into orbit. I also launched out of Kennedy instead of Korou, so performance to the ISS might be pretty shit.

Overall, this was really fun bringing a concept I’ve always found interesting into “life” (KSP RSS)

Nah, it’s the KNES + BDB + some other mods with configs. I slapped this together in an hour or so. The hard part was getting the boosters to not flip over during EDL, and then getting them to be able to fly back to the launch site.

Something that bothers me with the design in the paper is that ArianeSpace decided to give the Flyback Boosters a separate “skin” outside the propellant tanks. There are also two LOX tanks too, for some reason. The dry mass of the IRL boosters is quite insane - they are 54 tons dry and 222 tons wet. Ariane 5’s core is 14 tons dry and 184ish tons wet.

balloon has some benefits - satellites are zipping over the area quite fast, but a balloon can work with things like longer exposure, monitor movements over a relatively longer period and whatnot
plus they are also generally cheaper to launch
maybe the Chinese cameras on Chinese satellites aren't as good as the manufacturer claimed and can't get the details from that far at those speeds
or maybe they were probing US defences - whether or not the US could (or would) actually shoot down a stratospheric balloon like that
or maybe it was a weather balloon that lost control all along and boomers hyped themselves up into paranoid overreaction

>why shoot it down over the ocean? Wouldn't you want to study the wreckage of a supposed spying device?
The bits would hit ground at terminal velocity. Falling into water might actually break the fall somewhat.
it's probably easier to find wreckage in the ocean than in the populated areas with people taking bits and pieces as trophies or just throwing them in the bin.

The water wouldn't help cushion the fall much. Impacts at terminal velocity are pretty much the same no matte what you're coming down into. People grabbing bits and walking off with them would be an issue. I wouldn't be surprised if there were more than a few pieces of Columbia that ended up in private collections that way. There's also the bad optics of shooting it down only for it to land on someone like it's Dorthy's house. The media attention on the issue was already bad enough, but it could get so much worse if an inadvertent body count was attached to it.

Is there a way to minimize numerical error when calculating the position of a body in a Keplerian orbit relative to an arbitrary point? If you just calculate position using the standard polar-to-cartesian transformation with translation, you end up with large error for bodies close to the arbitrary point because you're operating on large values in search of a small one (relative position). I feel this should be possible and a solved problem, but I'm too retarded to find the solution.

They're not doing poorly. Most of their revenue is coming from satellite components and services rather than launches, but that's not unexpected given the relative size of those market segments.

A lot of Falcon 9's flight rate is on Starlink. If it wasn't involved in building out a mega constellation we'd be seeing a much more conservative number of launches.

The H3 could have carved out a commercial niche against ULA and Arianespace, but not SpaceX.

The LE-9 has ten times the thrust of the LE-5B-2. Using that as an upper stage engine would produce some wild acceleration curves.
