Is Space Commerce About to Become Real Commerce?

Why investors are following Musk, Bezos in betting on the stars, Washington Post

"The new space investors are catching up with the slow, but growing development of the commercial space sector, which NASA has been fostering for years. With the retirement of the space shuttle in 2011, NASA has awarded billions of dollars in contracts to commercial companies so that they could develop rockets to fly cargo and, eventually, astronauts to the International Space Station. Still, the industry is diverse, and different sectors are more advanced, and profitable, than others. Cubesats, the tiny satellites that can swarm around the Earth beaming back images of the planet, are already in high demand. Launching commercial and government satellites is also big business. But the emergence of other sectors, such as space tourism and asteroid mining, is still in the future."
