Beamed Energy for Space Exploration: Giant Leap or Incremental Steps?

Progress in space exploration and development used to come in “giant leaps.” Neil Armstrong’s “one giant leap for mankind” is perhaps the most well-known leap. As Armstrong stepped on the Moon for the first time, he was the living fulfillment of a decade-long endeavor that took us from barely being able to send someone into space all the way to sending multiple people to the Moon and back again. In 1977 the Voyager spacecraft were launched, taking us on a leap that gave us our first close-up looks at Jupiter and the planets beyond. Since then, we’ve achieved significant milestones of exploration and science, but, sadly, they’ve come at a much slower pace and few, if any, have achieved the status of being a giant leap. And that might not be a bad thing.

Giant leaps tend to be expensive and take many years to develop, fly, and achieve their goals—leaving them open to the vagaries of politics, changes in the economy, and the whims of those who fund them. So, what about the alternative? Is the incremental approach better or at least more sustainable?
