I don't know who is on first. I do know Jeb is cursed. (to be the most-flown Kerbalnaut among all Kerbals) How can you go to the ISS after it is finally considered outdated and deorbited?

Can I use a lot of fonts in just one post? Tell me @SkyFall2489

How hard can rocket science be anyways?

I would say tomorrow. EDIT: Not tomorrow. looking forward to June. http://www.cmse.gov.cn/gfgg/202109/t20210929_48817.html http://www.cmse.gov.cn/gfgg/202110/t20211006_48820.html It took the 2nd stage of CZ-7 Y4 9 days to fall to a pe of ~180km, and another 6 days to actually reenter.

Got it

@Elon Musk @Elon_Musk Sorry, I was trying to check if THE Elon Musk is actually on the forums. I think he doesn't have the time. But maybe his team could run an account for no reason... Seems impossible to me...

When speaking of electric... Solarpulse. A plane. It's wings are longer than that of Boeing 747s. But its mass is close to a household SUV. POWERED SOLELY BY SOLAR PANELS. Solarpulse. This plane did a circumnavigation in 2015. I was given a cap featuring this plane when I visited the Swiss Consulate in my city.

Status Update 4 hours after the previous one. That's all for today----fuel tanks with white and blue&white variants (stock variant system, not B9PS), and MM Patches to copy the tanks and change them into structural tubes. The collision mesh remains the same, so you can't walk your Kerbalnaut "into" the tubes. respository: https://github.com/CFYL/CParts This is not enough for a v1.1 release. If you are in a mood of "waiting", please be patient. Have fun.

Banned for mentioning other forum users in a thread @ColdJ

Status update. This is what we have for now. Engine flame rendered by Waterfall (new dependency) respository: https://github.com/CFYL/CParts

I wonder if Boeing paid to Squad/T2 or the opposite

I saw I was called, I had a meal, I went to another thread, I returned to this game, and wow! @ColdJ could be around.

Now, they should do this to Jeb Jeb can survive reentry, can't he?

Amazing. From Star Wars.

When I went to github to update my mod, I found his github account and respository are deleted. Cuz he made a localization file for my mod. I can still get the file but it is now a closed pull request. Sorrowful. https://github.com/CFYL/CParts/pull/1

Banned becaus you seem to live in the city of BANNING.

Nope. I hope @AtomicTech is around. That's only a very slim chance.

How do you coin one word to express "be given something to do"? Minor errors should be fine I guess.

Totally agree.

Both boys found worlds of brown brush to blow up bombs, though boys could not buy clocks to bury. Oxford knows why such forty ugly bossy busy monotonous words would work smoothly on forums though. Do not copy or count such forty words for your own good.

So... What subforums will be added in early 2023? I mean, if we still use this forum instead of starting a new one? I can think of a new Add-on subforum dedicated for KSP2, because KSP1 mods will possibly malfunction, if not useless, in KSP2. I think the devs has changed the file structure completely. And a KSP2 Technical support subforum? It seems to me that most other subforums can work well even when the two games are mixed together.

What about this? I drew these pictures with PaintDotNet. We build circular vacuum tubes ~1000km in diameter near densly populated cities. We link cities to the large circle with shorter tubes. We put airpumps and power plants near those tubes. We can also cover the tubes with solar panels. Intercity travel can be done through these tubes----There's no need of making a "web" with vacuum tubes because they are fast enough. Just link every city to a "freeway" and make trains run on the freeway. A travel route can be: cityA → train station → freeway → train station → cityB. The circular vacuum tube can be used as "freeway" as well as ground acceleration tubes. That can be two separate tubes placed close together -- one for suborbital, one for intercity. For the suborbital trains, we guide them to a slope tube. The slope tube is built on a geologically stable mountain to link the ground tube to 3-4km altitude. The "ground tube" in the following graph refers to the circular tube in the prior one. With these "two sets of tubes", we can manage distances within a few thousand kilometers, as well as beyond that. Accelerating to 3000m/s at 1g only requires ~5minutes. The suborbital flight can take passengers far away. A travel route can be: cityA on continent A → train station → circular tube → slope tube → suborbital flight → reentry → powered landing → cityB on continent B. (typo: powerede should be powered) I drew some circles on the map to show a few possible "circular tubes". As long as they don't go through deep, harsh seas, it should be fine. The acceleration tubes can give the train some 3km/s launch speed, so ΔV requirements of the train itself is trivial. Safety can be a problem though.

We may put train station on the ground. It's called space center. We may effectively accelerate the train with reaction engines fueled by UDMH+NTO or whatever. It's called rocket. We may effectively deccelerate the train with aero forces. It's called reentry. We may put the train to a complete stop by making ground contact. It's called landing. Known DISadvantages: Oh you need something as heavy as an aircraft carrier that FLIES to get the heavy train in orbit. ON THE GROUND a conventional carriage weighs ~20t and carries ~100 passengers. Effective mass per passenger is 0.06(passenger+luggage)+0.2(carriage average)=0.26t. I don't care about insulation in vacuum. I DON'T CARE. An SLS gets 70t(manned)/130t(freight) payload to orbit. So the train carries at most 269 passengers. That's way too costly. If you go suborbital and just reenter the atmosphere at the right point, you may get more. A vacuum tube on the ground "may" help you, somehow, get the train to the natural tunnel called orbit. We can replace reaction engines that fly with magnets that lie on the ground for easy maintenance.
