People have been vacationing in space for 15 years.
The first non-astronaut to visit the International Space Station was businessman Dennis Tito in 2001, who paid a hefty $20 million ticket price.
But now plenty of companies have sprung up with exciting plans to bring more people to space, for fares as low as $75,000.
But that price should decrease as the space tourism industry matures into a $1 billion market by 2022.
So if you are patiently waiting for your turn to see Earth from above, these are the companies that'll take you there.
There are a few companies that already developing ways to take non-astronauts into orbit, for a price.

But only one has, so far, actually pulled it off: Space Adventures.

Founded in 1998 by American entrepreneur Eric C. Anderson, Space Adventures was the first to launch a private citizen into space after it negotiated a seat on a Russian spacecraft headed to the International Space Station (ISS).
For a reported $20 million, the company launched businessman Dennis Tito (on the left in the image below) to the International Space Station in 2001, where he stayed for nearly eight days.

The company has launched six others to ISS since then, with the Russian space agency's help. It was set to take up singer Sarah Brightman last year, but she postponed her trip due to family reasons. The going rate these days is roughly $50 million.

Soon, the company will no longer be reliant on Russia to launch their customers into space. In 2014, Boeing got the green-light from NASA to take paying Space Adventures' customers to ISS on its "space taxi."
Astronauts — and possibly, private citizens — may also be flying in the Dragon capsule from SpaceX. The Elon Musk-led company made history in 2012 when it was the first private company to deliver cargo to the ISS, and return cargo to Earth.
So far, the Dragon has only delivered cargo, but it should soon be flying crew. The company says its first manned test flight should take place in two to three years.
Though it hasn't advertised so-called "space tourism" flights like others, its Dragon capsule would be an ideal vehicle. The company's overarching goal is to put an "average person" on Mars in the 2020s, for a price tag of $500,000.
Meanwhile, Space Adventures offers other add-on "experiences" to your ISS trip on its website like spacewalks — though no private citizens have done them yet.
And the company is currently planning a mission that will take two private citizens and a Russian cosmonaut around the moon and back, expected to take place by 2018.
Two people have already plopped down $150 million each for a seat. “We’re talking to the Russians about a series of missions, not just a one-off,” Space Adventures President Tom Shelley told DNews.
The company also announced plans for suborbital flights — shorter trips that go up and back down instead of orbiting the Earth.

Space Adventures is currently working with Armadillo Aerospace on a spacecraft, which it says will take two people to the edge of space, experience weightlessness for a few minutes, then bring them back down. The ticket cost will be around $100,000.
That price would be a fair bit cheaper than the cost of Virgin Galactic's planned suborbital trips — which would shuttle passengers to the edge of space for about $250,000.

Unlike Space Adventures, though, Virgin has already conducted numerous tests with its SpaceShipTwo craft, though it suffered a tragic setback after the ship broke up during its last test flight in 2014, killing the co-pilot and seriously injuring the pilot.

Virgin is still building its second SpaceShipTwo craft, which should be unveiled in February. It will have six passenger seats onboard.

One company offering serious promise is Jeff Bezos' Blue Origin, which launched and landed its reusable New Shepard space vehicle in November.
The company says it will give clients six minutes of weightlessness in space, and its maiden test launch may happen this year. The current rate for one seat right next to the pilot is $150,000.
If you're looking for a little bit slower of an ascent to suborbital space, Barcelona-based zero2infinity wants to launch people in its "bloon," a balloon-lifted pod made to carry people 22 miles above Earth.
It plans to charge about $125,000 for a seat in its capsule, which would carry four passengers and two crew on about a four-hour trip.
"Listen to your mp3s, have dinner, sip your favorite drink, or join the mile high club," the company says in its brochure. "It's calm, it's quiet, it's private. It's bloon."
In addition to the stunning view, the company says it will offer free cocktails and WiFi, in case you absolutely cannot wait to share that space selfie on Instagram.

But if you don't care all that much about the view from space, you can always settle for the zero-gravity feeling for relatively cheap.

A number of companies will take you up in an airplane that flies up and down in steep dives — simulating the feeling of weightlessness for 20 to 30 seconds at a time.
