Our past and our future: Explorer and SpaceX’s Falcon 9.

Explorer is the mock shuttle that people could walk through at Kennedy Space Center, but it still represents an era where space exploration was only done at extreme costs by government agencies. The Falcon 9 represents a much more affordable, privatized, and commercialized future for spacecraft. I can’t wait to see what the private sector puts out in the next few decades; if the advertising is anything to go by (stretching, I know), there is a whole lot to look forward too!
