I think it was in one of Rick Hartley's videos that he talked about designing for analog vs digital. There are a bunch of points I remember, in no particular order: - the frequency of your circuit, that you need to design for, is deter

Those are some impressive ramparts. Looking at them though, I wonder if they also had parapets and some sort of ladders or stairs to reach the top of them from the inside. It wouldn't at all be surprising, I think, for the archaeologic

The short answer to your question is that larger engines have very few advantages and many disadvantages. Specific impulse is the most obvious parameter of a rocket engine, but it's relatively less important for a first stage where thr

This is unsurprising. I doubt there was anyone with a modicum of understanding of the physics (even the teams doing the testing) who expected it to work. That doesn't, however, mean that testing it was a waste of time. There was an ano
