Volume 008.1 Intro Image.png

I finally managed to go on a research trip to Russia that I've been dying to do. I regretted not having enough prep time or resources when drawing the Soyuz rocket in the story, so on my trip, I was sure to visit the house where Tsiolkovsky was born, go to Star City, see an actual Soyuz rocket and hear a talk about astronauts.

Tsiolkovsky's old house actually had some of the research tools he once used while conceiving of the possibilities of multistage rockets, space stations and the like! I couldn't help but think about Senku.

Next time I get a chance to draw space and Senku together, it'll be so much better than before!
