The development of the Falcon series of launch vehicles has just been the most exciting progress made in the spacecraft era in decades [see "Rocket Science," April/May, p. 46], Elon Musk has gone from a launch vehicle that could put 400 pounds (2006) in orbit to a Falcon Heavy (February 2018) that can put 141,000 pounds in orbit. The plan for his BFR [Big Falcon Rocket] is to put 330,000 pounds in orbit and possibly make an attempt at getting to Mars and back by 2024. You can't accuse this guy of thinking small.
