As space launches increase, there aren't enough spaceports

More than 100 rockets took off into orbit from Florida’s Space Coast last year — a new record. And with more rockets taking flight each year, the availability of launch sites is becoming a bottleneck for the growing space industry.The Federal Aviation Administration (FAA) wants to make it easier for space companies to build new spaceports to make way for the increasing number of rocket launches. The agency has proposed waiving some environmental requirements for space launch. Daniel Ackerman has been reporting on the space industry as part of the Knight Science Journalism Fellowship at MIT.
