Yeah, this is obviously a very highly ambitious project, but I think that it is the right sort of ambitious. Even if their ultimate plans don't come to fruition, it should be very interesting to see what they accomplish. This is the sort of project where the journey is as exciting as the goal.

I'm a little surprised to see that they are going with pumped LOX instead of pressure-fed. With engines that small I would have expected the extra hardware to be a poor tradeoff.

I am the creator of this project. We are doing pump-feeding because we have to grow as designers and analysts. First stage engines are going to be 9 times more powerful and will definitely need pumps. It is way better to mitigate risks by designing small scale low-risk propulsion system early
