Returning rockets launch a new era in space flight
Watching a rocket blast off from a launch pad and accelerate at unnatural speeds into space is a sight and sound to behold. But seeing rocket boosters return from the edge of space back to where they started, as I did in Florida on Tuesday, is astounding. This week, the era of commercialized space flight took another giant leap forward with the launch of the Falcon Heavy, which sent a Tesla electric car into an orbit around the Sun that will take it out beyond Mars. It was a spectacular success for the first test flight of a new rocket.
