Let's see...
First, the cover.
I'm not much of an artist myself, but too bad your cover is somewhat too dim for a decent concept you're trying to convey. If you have access to Photoshop or GIMP, you could try tinkering with the brightness, contrast, levels, and colorization. Your goal is to make the two characters brighter (at least their rim lights) and the red sun even brighter, but not too bright that it loses the "red sun" image.
Next, your first chapter.
First paragraph doesn't really need that one em-dash. It will still deliver the same without. The other em-dashes are fine though.
Next, your dialogue style. I'll be honest, I'm not used to your style, and tend to dislike it. I can't even tell who is speaking which. But if you want to keep it as your own flavor, it's fair, your call.
If you're planning to move on to novel-style dialogues later on, let's see an example of what your dialogue would look like:
"And that's how we were able to become part of the Alliance," a voice exclaimed. "So, is there anyone in this audience who will say what kind of fuel humanity received from the Alliance?"
Lastly, I apologize that I could only grasp less than a half of what you were trying to convey in the chapter. I know, language barrier is an obstacle too real for many of us (I'm not even a native English speaker myself). But I watched Star Trek as a kid and I played Endless Sky; I'm a sucker for SciFi stories taking place in space. I wish I could read in your native language, because I know I might enjoy your story if language barrier isn't a thing.
I hope all the best for you. If you could collaborate with a decent translator, you'll be golden.
