      The Aerospace industry is more than just about fuel types or size of rockets.

      Efficiency and cost are the biggest hurdles. Its not clear how these solid propellents improve efficiency or reduce launch costs. Next up are controls and reliability.

      China has a “great” record for controls and reliability. They can’t even control where used rocket stages land. They’re consistently dropping used parts in populated areas, which also says a lot about their safety protocols.
