What is cool about the Dragon is that its capable of transporting seven astronauts to orbit and then soft-landing anywhere on Earth using thrusters and retractable legs with the accuracy of a helicopter. Then it can be refueled and launched again right away. That's not just in theory, here it is landing during tests. Also the first version of the Dragon has already been in space and docked with the ISS, so its been proven space worthy. That was unmanned though and parachuted back, so it's down to adding live people, how well the landing works after being in space, and how reusable it actually turns out to be. Still it's very exciting to see.
