2021 has been a busy year for private space tourism: overall, more than 15 civilians took a trip to space during this year. In this article, you will learn more about the space tourism industry, its history, and the companies that are most likely to make you a space tourist.

What is space tourism?

Space tourism is human space travel for recreational or leisure purposes. It’s divided into different types, including orbital, suborbital, and lunar space tourism.

However, there are broader definitions for space tourism. According to the Space Tourism Guide, space tourism is a commercial activity related to space that includes going to space as a tourist, watching a rocket launch, going stargazing, or traveling to a space-focused destination.

Brief history of space tourism

The first space tourist was Dennis Tito, an American multimillionaire, who spent nearly eight days onboard the International Space Station in April 2001. This trip cost him $20 million and made Tito the first private citizen who purchased his space ticket. Over the next eight years, six more private citizens followed Tito to the International Space Station to become space tourists.

As space tourism became a real thing, dozens of companies entered this industry hoping to capitalize on renewed public interest in space, including Blue Origin in 2000 and Virgin Galactic in 2004. In the 2000s, space tourists were limited to launches aboard Russian Soyuz aircraft and only could go to the ISS. However, everything changed when the other players started to grow up on the market. There are now a variety of destinations and companies for travels to space.

Space tourism companies

There are now six major space companies that are arranging or planning to arrange touristic flights to space:

  • Virgin Galactic;
  • Blue Origin;
  • SpaceX;
  • Boeing;
  • Axiom Space;
  • Space Perspective.

While the first two are focused on suborbital flights, Axiom and Boeing are working on orbital missions. SpaceX, in its turn, is prioritizing lunar tourism in the future. For now, Elon Musk’s company has allowed its Crew Dragon spacecraft to be chartered for orbital flights, as it happened with the Inspiration4 3-day mission. Space Perspective is developing a different balloon-based system to carry customers to the stratosphere and is planning to start its commercial flights in 2024.

Orbital and suborbital space flights

Orbital and suborbital flights are very different. Taking an orbital flight means staying in orbit; in other words, going around the planet continually at a very high speed to not fall back to the Earth. Such a trip takes several days, even a week or more. A suborbital flight in its turn is more like a space hop — you blast off, make a huge arc, and eventually fall back to the Earth, never making it into orbit. A flight duration, in this case, ranges from 2 to 3 hours.

Here is an example: a spaceflight takes you to an altitude of 100 km above the Earth. To enter into orbit — make an orbital flight — you would have to gain a speed of about 28,000 km per hour (17,400 mph) or more. But to reach the given altitude and fall back to the Earth — make a suborbital flight — you would have to fly at only 6,000 km per hour (3,700 mph). This flight takes less energy, less fuel; therefore, it is less expensive.

How much does it cost for a person to go to space?

  • Virgin Galactic: $250,000 for a 2-hour suborbital flight at an altitude of 80 km;
  • Blue Origin: approximately $300,000 for 12 minutes suborbital flight at an altitude of 100 km;
  • Axiom Space: $55 million for a 10-day orbital flight;
  • Space Perspective: $125,000 for a 6-hour flight to the edge of space (32 km above the Earth).

The price depends, but remember that suborbital space flights are always cheaper.

Is space tourism worth it?

What exactly do you expect from a journey to space? Besides the awesome impressions, here is what you can experience during such a trip:

  • Weightlessness. Keep in mind that during a suborbital flight you’ll get only a couple of minutes in weightlessness, but it will be truly fascinating.
  • Space sickness. The symptoms include cold sweating, malaise, loss of appetite, nausea, fatigue, and vomiting. Even experienced astronauts are not immune from it!
  • G-force. 1G is the acceleration we feel due to the force of gravity; a usual g-force astronauts experience during a rocket launch is around 3gs. To understand how a g-force influences people, watch this video.

Can I become a space tourist?

For now, the most significant barrier for space tourism is price. But air travel was also once expensive; a one-way ticket cost more than half the price of a new car. Most likely, the price for space travel will reduce overtime as well. For now, you need to be either quite wealthy or win in a competition, as did Sian Proctor, a member of Inspiration4 mission. But before spending thousands of dollars on space travel, here is one more fact you might want to consider.

Why is space tourism bad for the environment?

Rocket launches are harmful to the environment in general. During the burning of rocket fuels, rocket engines release harmful gases and soot particles (also known as black carbon) into the upper atmosphere, resulting in ozone depletion. Think about this: in 2018 black-carbon-producing rockets emitted about the same amount of black carbon as the global aviation industry emits annually.

However, not all space companies use black carbon for fuel. Blue Origin’s New Shepard rocket has a liquid hydrogen-fuelled engine: hydrogen doesn’t emit carbon but simply turns into water vapor when burning.

The main reason why space tourism could be harmful to the environment is its potential popularity. With the rising amount of rocket launches the carbon footprint will only increase — Virgin Galactic alone aims to launch 400 of these flights annually. Meanwhile, the soot released by 1,000 space tourism flights could warm Antarctica by nearly 1°C!
