SpaceX’s Starship rocket system reached several milestones in its second test flight before the rocket booster and spacecraft exploded over the Gulf of Mexico.

What aspect of this "has never been done before"? Its a multi-stage rocket (NASA and the Soviets have been doing that for about seventy-ish years and the Nazi scientists we all recruited were doing it for even longer). The main innovations are material choice (which is debatable) and landing a rocket on a pad, which is mostly a function of having good computers.
Space flight is hard. That said, there is a very strong argument for being much less iterative. Especially when the quest for a reusable rocket involves constant spraying of wreckage across oceans and land.
Launching a rocket is even easier, it's mostly a function of having a big tank of propellant and powerful engines. A big rocket ? Just need a bigger tank and bigger engines.
