I don't post much on the forums. Usually by the time I've read something and figured out what I think of it, somebody else has already said what I think. Anyway here are my thoughts:
I loved all the little details about the flight that you put in. From the comments about the water ballast needed to balance the Naga for flight to the control surfaces barely working at the altitude ceiling to the remark about shortening difference between max speed and stall speed, it was great. Admittedly, I am a huge sucker for stories about realistic space travel (aside from the bending), but I still think the attention to those details helps when crafting a story about Diqiu's version of the Apollo program.
On that note would also like to say that I'm glad that you didn't just copy the method that the actual Apollo program used. It shows consideration for the different restrictions this world is working under (for example: being unable to develop the ability to dock two space-craft means forcing a direct ascent approach).
I'd also like to give props to the presentation. The artwork is gorgeous. The little details again really shine here, like the image of a Polarbear-dog on the Naga's hull.
Anyway, I think that's everything. I of course have a ton of questions about the mission, but I suspect those answers will have to wait until the rest comes out :)
