[1.8.x-1.10.x] SmokeScreen 2.8.14 - Extended FX plugin (18 April 2020)

No, actually i meant this pyramid: I don't know how but the particles seem only to exist in a rectangular pyramid. Shouldn't it be a cone? -
No matter what you do to terraform Mars it will always need tremendous amounts of work and effort. The website mentions this at the beginning. It says whatever you do you'll need the ability to send thousands of people to Mars each year and transportation systems like Sänger or HOTOL for them. There must be a space station with living rooms for these thousands of astronauts which also can act as a fuel station, storage and construction yard for whatever is needed. You didn't visit the site, did you?

There is a website of the German Space Society which analyses different methods to terraform our neighbor planets: http://www.drg-gss.org/typo3/html/index.php?id=74 (Click here for bad google translation) The methods discussed: Greenhouse effect by reducing albedo of the polar caps Reducing of the albedo (currently 80%) to 6% (as dark as cole) can be done by covering the poles with dust. The dust can come from the greats deserts or just by letting Phobos crash on the poles. Result: The poles would absorb 13 times more solar energy, in numbers: 10 TW. This is nothing compared to what the Mars already absorbs: 30 000 TW. Using bacterias to change the composition of the atmosphere It is proposed to bring genetically engineered bacterias to mars (a few hundred tons - that's feasible) which will convert the atmosphere to biomass. Result: There is not enough water. The grow of the biomass will stop at some point. Unfortunately this point is faraway from the point of really changing the atmopshere. Putting Greenhouse gases into the atmosphere The basic idea is to build factories on Mars which produce CFC (FCKW in German) which is released into the atmosphere. Result: At least 400 mio tons of CFC are needed. 1990 the factories on Earth produced 2 mio tons. It is still unknown if the gases really contributes to the Greenhouse effect in the scale we think of. Evaporating the south pole with a giant mirror in orbit The evaporation of this pole will add about 100 millibars to the atmosphere which makes a great difference. Why the south pole? There is water ice! We need a giant (250 km diameter) mirror made of aluminum to pull this of. The aluminum can be prospected from the Moon an brought to Mars. Result: It will take a lot of time (>100 000 years) and 200 000 tons of aluminum but it is possible! We can expect an about 5 degrees warmer Mars. A greater mirror will heat the Mars even faster and more. Nuclear mining (who tough of that name?) Detonating nuclear bombs underground will heat up the ground which itself releases CO2. Unfortunately we will need 2.8 mio megatons or 500 mio fusion bombs. I doubt there is enough uranium or plutonium in the vicinity to ignite that many fusion bombs. And how long do we need to dig 4 mio holes with a depth of 1000 meters? Impacts You can use comets, asteroids or small moons (like Hyperion or Enceladus) and let them strike the Mars. This will heat the planet a lot. The problems are the composition of these objects (they can consist toxic substances), needed amount (up to 300 000 asteroids) and their propulsion. It is also unknown what other effects can occur and in what magnitude, e.g. a large object can blast half of the atmosphere away. In my opinion we shouldn't try to teraform Mars. Instead we should dig far into (hundreds of kilometers) the deep and build a colony there. In this deep there will be a gravitation acceleration of 1 g, a breathable atmosphere can be created and people are shielded from dangerous interstellar radiation. I don't think people will ever walk on the surface for an extended time let alone live on it.

Most (or all?) engines in KSP are only usable in special circumstances. For example the Mainsail is good for early stages of a heavy rocket. The Skipper is the same but for higher stages. The Poodle is good for orbital maneuvers of such a rocket. This all works because different atmosphere thicknesses at different heights requires adapting. In space there is no atmosphere so the difference between more thrust/less ISP and less thrust more/ISP becomes the main deciding factor of what engine to use. If there's an engine which has a higher ISP and small drawback like the need for a nuclear reactor I would always choose the later engine over the LV-N. In fact your proposed engine is so good there is no reason to not use it. It only needs a high amount of electricity and a little bit of fuel. Maybe I can swap some fuel tanks for some solar panels. It makes the craft lighter while providing the energy need. The thrust is about half of that of a LV-N but I don't care. I just put two of your engines on my rocket. It's still more efficient. It's the ultimate engine for interplanetary flights. Your proposed engine would break the balance of all available engines.
-
It should has a thrust of 2.5 Newton and an ISP of 20.000 s. That's what RL ion engines can do. Squad boosted the thrust so nobody has to wait for months for completing maneuvers.
-
Do we really need another LV-N? The ion engine is already bosted in terms of thrust and nerved in terms of ISP. In it's current form it is the engine for tiny and small probes.

Why does it look like a pyramid? -
Updated to KSP .23 8 MegaPixel Kerbin map image.
*Aqua* replied to Pds314's topic in KSP1 Discussion
Thank you for what you have done. It must have been quite tedious. I like the result. Kerbin hase a nice set of surface features. It would be great if there are a bit more deserts at the equator and jungles! Edit: @Pds314 Is there a way to make 5760x1200 (3* 1920x1200) wallpaper out of it? It obviously needs a rework of the colors as they are a bit bright. -
Edit: Didn't read right. Edit 2: I got the outer aspargus ring working without flaws. Maybe you attached the fuel lines between the wrong tanks? That's one hell of a rocket. I couldn't set the throttle above 50% or the engines overheated. The rocket only climbed up to 2 km and then fall down because of too low TWR. Split it up into several rockets und assemble your interplanetary ship in the orbit. That makes constructing lifters and acending easier. ~500 parts also caused incredible low frame rates - that's not fun. An use less struts! For example the outer aspargus ring should work with only 2-3 struts per tank (2 on each side above the decoupler, one in the center below it or the other way around). Also have a look at this mod . It makes your rockets less wobbly. You will need even lesser struts with it.

Unglücklicherweise sind 15 Unterrichtsstunden ein bisschen wenig. Ich glaube nicht, dass du schon verstanden hast, wie die deutsche Sprache im Wesentlichen aufgebaut ist. Du könntest mit einem Tandempartner höchstens über "Guten Tag" oder "Hallo" reden. Das hilft dir aber nicht viel weiter. In einem Jahr oder so hast du erst genug gelernt, um mal direkt mit einem Muttersprachler zu reden. Wenigstens müsstest du dann nicht dauernd in ein Wörterbuch schauen, wenn jemand was sagt. Das frustriert auf Dauer ziemlich. Unfortunatley 15 hours of classes is a bit too little. I don't think that you already aquired a general understanding how the German language works. A tandem partner could only talk about a 'Guten Tag' and 'Hallo' with you. This won't help you much. In a year or so you'll have enough knowledge to try talking with a native. At least you won't have to look into a dictionary each time someone says something. This is frustrating over time.

Fundamental Design Flaws in Career
*Aqua* replied to Sauron's topic in KSP1 Suggestions & Development Discussion
@Sauron Yes, game balancing is an iterative process. But there is no reason for an iteration each time there is an update. Let's assume Squad now takes a break from adding new things and instead rebalances whatever needs to be rebalanced. Let's assume this takes about the usual update cycle time. After that they add the contracts system and again has to rebalance some stuff. Because of the added features Squad has to rebalance more stuff. Each update the work increases and therefore development slows. I'm not saying they should stop rebalancing but it's unwise to do it often. -
It's a technical limitation. The faster time passes the less exact physics calculation will be. When your computer can't keep it up (indicated by a yellow or red time display) it will skip some stuff so it can keep up. This can result in phantom forces and more instability as the intervalls between calculations are getting larger.

Fundamental Design Flaws in Career
*Aqua* replied to Sauron's topic in KSP1 Suggestions & Development Discussion
The game is in alpha phase. We don't know everything what Squad will add to it. Balancing (and this seems to be the main critism here) is usually done as one of the last points in the development process because everytime they add something new something old has to be rebalanced. Over and over again. This is just wasting time and work. -
Unity uses floats to calculate positions and stuff. The maximum positive value of a float is 3.4028234 * 10^38 which is about 36 sextillion lightyears in KSP. You can't reach that distance. The kraken will strike way before that when the number density gets too low.
