Yeah, I was expecting a low-code/no-code way to build queries in a GUI and wondering why any company wouldn't jump at that (at least based on my own experience). Instead, I feel like this is a really nice SQL "IDE"
My understanding is as follows:
Lower orbits are faster because you need more radial ("forward" or outward) velocity to keep the orbit in equilibrium with the stronger pull of gravity as you get closer to the orbited body. In to reach a lower orbit from a higher one, though, and thus go faster, you essentially must slow down (remove energy) to fall toward the body which results in a faster speed when you reach the other side of the orbit
