The opportunity to become a space tourist is available to units, since the cost is measured in millions of dollars. So, a flyby of the Moon will cost $ 75-120 million, ten days on the ISS - $ 50-80 million, in near-earth orbit - $ 30-40 million, a suborbital flight - $ 200-300 thousand. The spacewalk will cost the space traveler $ 200 million. For 2020, space tours are carried out only by Roskosmos together with the operator Space Adventures. They promise to send Virgin Galactic, Blue Origin, CosmoCourse to the stars in the near future. But Elon Musk's SpaceX is still considered the leader in a promising industry, which promises to carry out the next flight for money already in 2021
The main technological news of August 2020 about the splashdown of the capsule with astronauts from the first private spacecraft Crew Dragon and the successful test of the Starship prototype launch for a flight to the Moon and Mars showed that the promises of entrepreneurs to send people into space are not working exceptions, but on an ongoing basis, will soon become a reality. And, perhaps, for this you don't even have to wait more than 10 years - that is how much has passed since the flight in 2009, when the Canadian Guy Laleberte became the eighth and last space-tourist. The first lucky ones for the opportunity to stay on the ISS for 10-14 days paid $ 20-30 million, today the service has significantly risen in price. How much it costs to become a space tourist directly depends on the type of flight, the amount can reach $ 200 million.
Reaching the Karman line is a criterion for recognition of a space flight. The blue sky ends at an altitude of 100 km - this figure is called by the International Aviation Federation. NASA, when determining the border, speaks of 122 km, and the US Air Force counts anyone who has been above 80 km as real astronauts.
But private companies, offering space-tourist services, focus not only on height, but also on creating conditions for being in zero gravity. Already today you can try zero gravity on yourself by paying for a flight on a super-high-speed plane, or feel the load on special. simulators in Star City.

All these near-cosmic emotions cannot convey the euphoria that travelers should experience when looking at the stars through the window. Real space tourism is considered today as a flight:
Each type implies different costs for organizing the flight, the timing and complexity of the preparation of the tourist himself, requests from operators. Therefore, the prices for such services can differ significantly and range from $ 200 thousand to $ 200 million.

For relatively little money, clients are offered to rise above the horizon for a few minutes and experience weightlessness. The rocket plane with 6 tourists lifts the carrier plane, after undocking the ship rushes upward. The capsule reaches its highest point at the moment the engines are turned off, it is at this moment that passengers can soar in the cockpit and admire the beauty behind the windows. After that, the “fall” downward begins. The microgravity time depends on the altitude and the gained speed and is 3-5 minutes.
Cosmos Agency • Space tourism • Suborbital and orbital space tourism, what's the difference?
Suborbital and orbital flight are two completely different things. Comparing a suborbital rocket to an orbiting rocket is like comparing a car that moves at a speed of no more than 30 km/h to a car that easily reaches 200 km/h. The difference is fundamental, and we will now try to explain it.
To understand what orbital is, imagine you are throwing a ball. At any point on the Earth, the trajectory of the ball will be close to a curve called a parabola. The harder you throw the ball, the straighter (less curvature) its trajectory will be. If the ball is thrown very hard, the curvature of its trajectory can approach the curvature of the Earth. Moreover, if the ball is thrown into the vacuum of space, it will fly around the Earth without falling to the surface. This is exactly what happens when a satellite is launched, when it is successfully "thrown" by a rocket into orbit around the Earth. In this case, we are talking about an orbital space flight.
We consider suborbital flight as any flight outside the Earth's atmosphere with a maximum speed below orbital. If the rocket does not reach orbital speed, it begins to fall to Earth and returns to the atmosphere within minutes of shutting down the engine.
A rocket moving along a vertical trajectory will reach its highest point when the engine is turned off. Here are some examples of the speed required to reach a given vertical altitude:
Altitude Required speed 100 km 950 m/s (2.9 M) 200 km 1650 m/s (5.1 M) 400 km 2500 m/s (7.7 M)
When the rocket leaves the atmosphere and its engine is turned off, passengers will experience an imaginary weightlessness and will be able to soar freely in the cockpit if their seat belts are unfastened.
Microgravity ends when the rocket re-enters the atmosphere. How long the microgravity zone will last depends mainly on the altitude gained during the flight. Some examples:
