A comparison conversation between orbital and suborbital Featured

Differences between orbital travel and suborbital travel Differences between orbital travel and suborbital travel

 

In recent years, spaceflight has ceased to be strictly scientific in nature and has become commercial. Important private companies have started an interesting race to develop space tourism, which is why now the concepts of orbital flight and suborbital flight are heard more frequently.

Differences between orbital travel and suborbital travel

And although both concepts are usually mentioned in the same conversations or topics, they are substantially different. Their main differences lie in the trajectory and the speed that each one implies.

The trajectory

On the one hand, the trajectory of an orbital flight travels the circumference of the planet constantly, with a speed such that it can travel around the Earth infinitely. On the other hand, the trajectory of a suborbital flight begins with the takeoff of the spacecraft, which goes out into space and draws a retreating arc to return to Earth. Regardless of how far the spacecraft traveled when it went out into outer space, it was never in orbit. That is, it never went around the planet, therefore it is classified as a suborbital tour.

The speed

When it comes to speed, a spacecraft that is going to make an orbital trip needs to reach what is called "orbital speed". For its part, a rocket that is going to execute a suborbital flight needs a speed much lower than that.

Now, what is known as orbital speed is the speed with which an object must move in order to keep orbiting around the Earth or any other planet.

To get a much clearer idea, suppose that a spacecraft must orbit our planet 200 kilometers away. To achieve this, the spacecraft must reach a speed of 28,000 kilometers per hour.

If it is a ship that must perform a suborbital flight, the required speed is much lower since it must not reach the orbit of the planet. As we already mentioned, this type of vehicle only leaves the Earth, reaches a certain height in outer space and returns to our planet when its engines are turned off. Suppose that the spacecraft wants to reach 200 kilometers from the Earth, to achieve this it requires moving at a speed of 6,000 kilometers per hour, which is considerably lower than the speed required by an orbital transport.

The technical aspect

Another aspect to consider is that due to the speed required to achieve orbital flights, these are much more complex at a technical level, which translates into higher costs when compared to suborbital flights. That is why suborbital tours are becoming more attractive for companies seeking to develop the trips to outer space.

And although these do not revolve around the planet, they provide a very interesting route since when they reach the maximum point of the arc of flight, the ship reaches weightlessness as it begins to return to Earth providing its passengers with a free fall and an unmatched view.

Space tourism a current reality

And although the technological and monetary difference between one type of flight and another is notable, private companies focused on space travel have managed to offer both options to their customers. Of course, these flights are extremely expensive in the first place, but it is hoped that as this industry develops, tickets may become more affordable.

Regarding the achievements made by the main companies involved in the development of trips to outer space, we have the following:

 

  • On the one hand, Richard Branson's Virgin Galactic offers suborbital flights that can be more easily afforded by those with enough money to travel off-planet. In fact, Branson himself traveled in the company of other passengers on what was considered the first space tourism flight.

 

  • On the other hand, Elon Musk's company, Space X, has managed to send the first civilian crew into outer space on an orbital flight. The four crew members circled our planet for three days, enjoying this form of space travel at its best.

 

Both companies continue their advance when it comes to take tourists off the planet, and we are fully confident that we will continue to witness what both can achieve in the short and medium term.

Without a doubt, human beings have already managed to develop the necessary technology to gradually begin to conquer space. Commercial flights outside the Earth are already a palpable reality, although affordable for few. However, we hope that the tourism in outer space industry will reach higher levels in the technological aspect, and that it will be much more accessible for the thousands of people who dream of traveling to the stars.
