REUTERS/Joe SkipperLOS ANGELES, April 20 (Reuters) - The spectacular explosion of SpaceX's new Starship rocket minutes after it soared off its launch pad on a first flight test is the latest vivid illustration of a "successful failure" business formula that serves Elon Musk's company well, experts said on Thursday. PRACTICE MAKES PERFECTAt least two experts in aerospace engineering and planetary science who spoke with Reuters agreed that the test flight delivered benefits. "This is a classical SpaceX successful failure," said Garrett Reisman, an astronautical engineering professor at the University of Southern California who is a former NASA astronaut and is also a senior adviser to SpaceX. Reisman called the Starship test flight a hallmark of a SpaceX strategy that sets Musk's company apart from traditional aerospace companies and even NASA by "this embracing of failure when the consequences of failure are low." She said the risks of a single flight test were small in comparison to the ambitious gains at stake.
