- First, the landing engines called the "SuperDraco Thrusters" are actually 3D printed out of Inconel (a nickel-chromium superalloy), each with 16, 000 pounds of thrust.
- Second, the Dragon-2 capsule lands using rocket thrusters. Gone are the parachute splashdowns. Now Dragon-2 can land anywhere on Earth with the precision of a helicopter.
Such a powered landing is the first step towards landing on Mars, where the atmosphere is too thin to use parachutes for a soft touchdown.
Mars, after all, is Elon's ultimate goal. Last October I was on stage with him, interviewing him at a Goldman Sachs event for an audience of entrepreneurs, and I asked him for a prediction on the timeframe and cost for taking private passengers to Mars. His answer?
- It's only 15 years away.
- For a total cost per person of $500, 000
The message here is the following:
Elon had no experience in the rocket business when he started 12 years ago. Yes, of course he's a genius, but beyond that, he has surpassed what NASA, Lockheed, Boeing, Russia and China are able to do in space.
