Some further thoughts...
- The spacecraft's landing system is interesting. Two of its three legs are moveable, and it also has a pair of control surfaces near the nose. According to the information, these four control surfaces steer the spacecraft as it dives into an atmosphere at a high angle of attack, while its speed drops to under supersonic. The spacecraft then turns vertical to fire rockets to land. Sure, it all makes sense - at this stage of the mission the spacecraft is going to have a high volume for low mass, so it's going to have a relatively low terminal velocity.
But what interests me is that the one spacecraft design appears to apply for landings on Earth, Moon and Mars, which (obviously) have very different amounts of gravity and atmosphere (unless there was something I missed when I skipped bits). So I assume they have robust maths to demonstrate that this method will work with a Mars landing rather than just an Earth landing, which was all they appeared to demonstrate.
- The spacecraft appears to store some cargo under its base, in the space between the engine bells and the stage skirt. I assume the logic is that the spacecraft's engines fire up only when its up so high there's virtually no atmosphere to conduct or convect heat from the combustion chamber to the adjacent cargo pods. But again maybe that's something I missed as I skipped through the video.
It'll be interesting to read what industry experts have to say about all this.
