LOS ANGELES — If floating weightless and peering down on a shimmering-blue Earth sounds appealing, you might consider being a space tourist.
As long as you've got a fat wallet.
Two years after the first privately financed space flight jump-started a sleepy industry, more than a dozen companies are developing rocket planes to ferry ordinary rich people out of the atmosphere.
Several private companies will begin building their prototype vehicles this summer, with plans to test fly them as early as next year. If all goes well, the first tourist could hitch a galactic joyride late next year or 2008 — pending approval by federal regulators.
Unlike the Cold War space race between the United States and Soviet Union that sent satellites into orbit and astronauts to the moon, this competition is bankrolled by entrepreneurs whose competition could one day make a blast into space cheap enough for the average Joe.
"This time, it's personal. This space race is about getting 'us' into space," said space historian Andrew Chaikin.
Breaking into an exclusive club
For now, commercial space travel remains an exclusive club.
Over the past few years, three tourists have paid a reported $20 million each to ride aboard a Russian rocket to the orbiting international space station.
A fourth would-be tourist — Lance Bass from the former boy band 'N Sync — did astronaut training, but failed to come up with money for the trip.
The three who made it spent about a week weightless and described the experience as "paradise" and "wondrous." The most thrilling part for millionaire U.S. scientist Gregory Olsen, who blasted off last year, was viewing the swirling Earth from the dark of space.
Prospective prices for the next round of personal space flights aren't so astronomical. A seat aboard one of the yet-to-be-built commercial spaceships will fetch $100,000 to $250,000. Space entrepreneurs expect the price tag to drop once the market matures.

Tourists will get what they pay for.
Instead of days in space, the commercial spaceships under development will only reach suborbital space, a region about 60 miles (100 kilometers) up that is generally considered the beginning of the rest of the universe. Since the private spaceships lack the power to go into orbit around Earth, the flights are essentially up and down experiences — lasting about two hours with up to five minutes of weightlessness.
It's more of a ride than those offered by several companies that use Boeing 727s to produce a half-minute of weightlessness through a series of maneuvers about 25,000 feet (7.6 kilometers) up. Those flights, which generally sell for about $3,000, never reach space.
"It's like an upside-down bungee jump," said John Logsdon, director of the Space Policy Institute at George Washington University. "There'll be a few moments to view the Earth and then you come right back down."
Here is a rundown of several companies that will start building their private spaceships this summer:
The biggest name is Virgin Galactic, a space tourism firm founded by British billionaire Richard Branson. Branson has partnered with Burt Rutan, whose SpaceShipOne in 2004 became the first private manned craft to reach space, to build a fleet of suborbital commercial spaceships nicknamed SpaceShipTwo.
SpaceShipTwo is about the size of a corporate Gulfstream jet that can hold six tourists and two crew members. Like SpaceShipOne, it will be powered by a hybrid rocket motor and use a "feathering" technique to glide back to Earth.
The design of SpaceShipTwo is complete, and construction is slated for this summer, with test flights scheduled for late next year. The project's $100 million first phase is financed by Branson's Virgin Group, said Virgin Galactic president Will Whitehorn.
"This is a project not without risk," Whitehorn said recently. "It's our goal to be the first ones to do it safely."
Oklahoma-based Rocketplane Kistler is one of Virgin Galactic's biggest competitors. Rocketplane Kistler, whose main investor is American businessman George French, hopes to start test flights next January and fly commercially by next summer. French owns several businesses, including a space education company in Wisconsin.
"It's the beginning of a whole new era of commercial space travel. Someone's got to do it and we want to be the first," said company vice president John Herrington, a former NASA astronaut who will perform the suborbital test flights.
Space Adventures, a Virginia-based space travel agency best known for brokering three tourists to the international space station, is the latest entrant.
Another venture organized by Space Adventures would erect a spaceport in Singapore as well.
PlanetSpace, a Canadian-American venture backed by telecom entrepreneur Chirinjeev Kathuria, is building a 54-foot-long (16-meter-long), three-seat suborbital rocket that would launch from somewhere in the Great Lakes region and re-enter Earth by splashing into the water. It hopes to fly 2,000 passengers in the first five years, beginning in 2008.
"It's changed from being a giggle factor to being heralded as a new business," said Geoff Sheerin, PlanetSpace's president and chief executive. Sheerin founded Canadian Arrow, a private rocket company that unsuccessfully competed for the X Prize in 2004. Kathuria also has prior experience in space ventures, having contributed to a private effort to keep Russia's Mir space station going until its fiery fall in 2001.
How much demand?
Some market studies have shown the public has an attitude of "If you build it, we will come." Futron, a Bethesda, Md.-based aerospace consulting firm, estimated that revenues in the infant space tourism industry could exceed $1 billion a year by 2021, with the greatest demand in suborbital flights in which passengers spend mere minutes in space.
Before tourists can lift off, several federal hurdles must be cleared. Federal regulations that will govern human space travel and spell out safety and training requirements are expected to be wrapped up this summer.
Transportation Secretary Norman Mineta last month told a gathering of space entrepreneurs that the government would move swiftly to grant space travel licenses to companies that can prove they can operate safely.
That's good news for people like Chaikin, the space historian.
"I've been hoping and dreaming all my life to go into space. Now I actually have a shot of doing it."
