kurzaen Posted March 4, 2019 Share Posted March 4, 2019 In my many playthroughs of ONI, I've tried building rockets, petroleum, engines, steam engines, cargo bays, and the captains quarters, but no matter what, wherever I build the scaffolding, it always says that the rocket is unusable, that it can't go anywhere on the spacemap. I've fueled the engines, powered the scaffolding, and trained my duplicants, but I just can't ever seem to get it to work! Does anyone have any blueprints I can use? Or tell me what I'm doing wrong?

yoakenashi Posted March 4, 2019 Share Posted March 4, 2019 @kurzaen When you select the command module, you should see a checklist of items above a list of astronaut capable duplicants. Are there any items still highlighted red with no check in the box? Once you have all of these, completed, you then need to send an active automation signal to the command module input to launch the rocket.

SharraShimada Posted March 5, 2019 Share Posted March 5, 2019 4 common mistakes: 1. the gantry (the extendable walkay) has to be exakt benath the command module. 1 tile to the left or right, and the astronaut wont be able enter. That results in the "missing gantry" message of the command capsule. 2. Petroleum engines and hydrogen engines need an oxidizer tank. Either solid (oxylite) or liquid (liquid oxygen, often called LOX). Without a filled oydizer-tank, your rocket will go nowhere. 3. You need fuel-tanks to provide the engines (not for steam engine, They have the tank included) 4. Overloading the rocket. Yes it looks cool to build a rocket with 5 research modules and 5 cargo bays of some sort, but its all weight you add to the rocket. Weight means you need more fuel. More fuel means, you get more weight, therefore you need more fuel.... For example (thats fictive values, not real ones): If you need 1400 kilograms of petroleum to reach a destination with your current rocket, you set one fuel tank to 900 (the max) and a second one to 500 kilos. It makes no sense to carry a third fuel tank, because this one would add dead weight, causing more fuel-consumption. And it makes no sense to fill both nedded tanks to the max, because you would carry 400 kilos of not needed fuel, causing more fuel need, and the remaining, not used fuel would be wasted, because the rocket will always come back with empty tanks. (There is currently a bug, returning rockets will filled tanks, but dont rely on this for long) There is a web-tool to calculate modules to oxydizer and fuel-ratio, https://oni-assistant.com/ As one of the others posted, just select the command module, and it shows you valuable information For exmaple the rocket is not suitable to reach the set destination. This means, your rocket is to heavy for the given amount of fuel, or you´re missing oxydizer. And in the space-menu itself, when selecting the rocket, it will show you every detail. If the tanks are filled, but the reachable distance is 0, this means either you dont have oxydizer, so the rocket wont burn at all, or you have to many modules, so the weight penalty exceeds the thrust provided. As general rules: more than 5 research modules are a waste, because every destination has only 5 one time research spots. If you explored them, there is no need to send a research module there again. A steam engine can support 5 research modules to a destination of 10k km, and to 20k km with a solid fuel thruster added to the steam engine. There is currently no way (i´m aware of) to send a rocket with >3 cargo bays (of any kind). And 3 is only possible with high-tier rockets (liquid hydrogen and liquid oxygen) Lower tier rockets (steam and petroleum engines) will only alow 1 or 2 cargo bays at all.

Just last night I launched my rocket via the star map screen and clicking the launch rocket button. Sorry for the misinformation.
