May 22, 2012 -- intro: The SpaceX Falcon 9 rocket safely launched from Cape Canaveral Air Force Station before dawn today, carrying a Dragon capsule with 1,000 pounds of supplies for the International Space Station -- and, much more important, the hopes for a new way of doing space travel.
"Falcon flew perfectly! Dragon in orbit, comm locked and solar arrays active!!" came a tweet from SpaceX's founder, Elon Musk. "Feels like a giant weight just came off my back."
The SpaceX launch was, in many ways, routine. It was an unmanned rocket taking off from Launch Complex 40, a pad NASA and the Air Force have used since the 1960s. If all goes well, it will make a rendezvous with the space station early Thursday morning, and if that's successful, the station astronauts will use their robot arm to pull the capsule in for docking on Friday.
The one major difference is that SpaceX is a private company. Until now, all flights to the space station have been made by the U.S., Russian or European space agencies. NASA hopes SpaceX and other commercial firms will take over the job previously done by American space shuttles and Russian Progress supply ships.
"Every launch into space is a thrilling event, but this one is especially exciting because it represents the potential of a new era in American spaceflight," said John Holdren, President Obama's assistant for science and technology. "This expanded role for the private sector will free up more of NASA's resources to do what NASA does best -- tackle the most demanding technological challenges in space, including those of human space flight beyond low Earth orbit."
Musk is part of a new breed of celestial aspirants -- entrepreneurs who made their fortunes here on Earth, and now look to the skies for new worlds to conquer.
There is a cynical saying sometimes used that you really can make a small fortune in space -- all you have to do is spend a large one. But Musk and his competitors argue that since they are not burdened by government bureaucracy, they can do cheaply what NASA has done expensively.
They say space could be a bit like the old West: Governments sent explorers, such as Columbus or Lewis and Clark, to open the frontier, and then private settlers followed.
Here is a list of some would-be space settlers and their projects:

Elon Musk, now 40, made his fortune online. He co-founded PayPal, the popular system for sending money by email, in 1999, and sold it to eBay in 2002. The purchase price: $1.5 billion in stock. Musk owned about 12 percent of PayPal at the time.
It was not even his first company. In 1995 he dropped out of Stanford's graduate school to start Zip2, a firm that made software for publishing content on the Internet.
He began SpaceX in 2002, saying he believed humanity's future lay in space. The philosophy of his Falcon rockets and Dragon capsules, he told ABC News, was to keep it simple: "We're building trucks, not sports cars."
Several early launches failed. But in 2010, a SpaceX Falcon 1 rocket became the first liquid-fueled booster to put a satellite in Earth orbit as a private venture.
His principal client is now NASA. SpaceX hopes to carry cargo -- and eventually astronauts -- to the International Space Station, something NASA has been unable to do since the space shuttles were retired in 2011. media: 16371616 caption: use related:
quicklist: 2 category: Millionaire Space Pioneers title: Sir Richard Branson, Virgin Galactic url: text: Richard Branson started setting records in the record business. He began what became Virgin Megastores in 1972, selling music in England at discounts not seen before.
As his fortunes grew, he expanded into Virgin Atlantic Airways, Virgin Mobile cellphone services, medical care and other ventures.
He was not just a risk-taker in business. He was a serial adventurer, trying to set records in sailing, ballooning, auto racing and flying.
Then came Virgin Galactic. Branson says there is a market for people wealthy enough to spend, say, $200,000 for a short ride to the edge of space. He has teamed with the designer Burt Rutan to build SpaceShipTwo, which would carry paying customers more than 60 miles above the ground. Virgin Galactic claims that more than 500 prospective customers have signed up.

quicklist: 3 category: Millionaire Space Pioneers title: Paul Allen, Stratolaunch Systems url: text: In 1975 Paul Allen moved to Albuquerque to start a software company, persuading a childhood friend to drop out of Harvard to come join him. The friend was Bill Gates. Allen thought of a name for the firm: Micro-Soft. The rest you know.
Allen, now 59, was the less public of the Microsoft pioneers. He stopped playing an active role at the company after fighting off Hodgkin's lymphoma in 1982. Since then, he's been an investor and philanthropist, putting his money into everything from sports teams (football's Seattle Seahawks and basketball's Portland Trail Blazers) to life in space (a vast array of radio antennae, designed to listen for signs of extraterrestrial intelligence, was built in northern California with his money).
In 2004, with Rutan, he won the Ansari X Prize -- $10 million to the first private company to send a ship more than 100 km (about 62 miles) into space. He did not exactly need the cash. In December 2011, he announced Stratolaunch Systems, a company that would use a giant dual-bodied jet plane to carry a SpaceX rocket into the air. The rocket, launched from cruising altitude instead of the ground, would save thousands of gallons of fuel on its way to space.

quicklist: 4 category: Millionaire Space Pioneers title: Jeff Bezos, Blue Origin url: text: Jezz Bezos said he chose the name Amazon for his website principally because it came early in the alphabet. It has become the world's largest online retailer.
Bezos has also revealed, quietly, that he is a space enthusiast. He started a company called Blue Origin, testing prototypes of reusable spacecraft in the Texas desert. Few other details have been made public.
This spring, Bezos also revealed that an expedition he backed had found what he says is probably the first stage of the Saturn V rocket that launched Apollo 11 to the moon in 1969. It would be thousands of feet beneath the surface of the Atlantic, off the coast of Florida. Its five F-1 engines -- still the most powerful ever made -- may still be intact. Bezos said he would like to recover them and return them to the American people, to whom they belong.

He's expanded the idea into space. His Bigelow Aerospace has already launched two Genesis inflatable space modules, which he says could someday be used as orbiting laboratories, space station components, factories -- even extended-stay hotels.
When he uses the word "inflatable," don't think of a balloon. The Genesis modules, he says, would be more like tires. They would be compact for launch, but strong and durable in orbit.
