La visione di Elon Musk e della sua SpaceX per immaginare l'esplorazione commerciale delle spazio.
You can be rich enough to buy a rocket and still get sticker shock. In early 2002, PayPal co-founder Elon Musk, already a multimillionaire at 30, was pursuing a grand scheme to rekindle public interest in sending humans to Mars. A lifelong space enthusiast with degrees in physics and business, Musk wanted to place a small greenhouse laden with seeds and nutrient gel on the Martian surface to establish life there, if only temporarily. The problem wasn’t the lander itself; he'd already talked to contractors who would build it for a comparatively low cost. The problem was launching it.
