Many people may have watched many SF movies. In these movies, people travel the space and discover other planets. After they watched the movies, most of them may think that traveling in space is just a story. However, it is not. Actually, many space-traveling companies have already started to launch their spaceships.

▲ The process of the flight of SS1

The process of the flight of spaceships is not much complicated. After the launch, they reach 15 kilometers for 65 seconds. When they reach 45 kilometers, they use the whole fuel. However, they go up about 45 kilometers more because of the inertia. When they come back to Earth, they can be explored, so their wings are folded perpendicular to the direction of flight for higher air resistance. Lastly, they usually fall into the sea.

▲ Space X launched the spaceship.

Nowadays, many companies are studying space traveling. Virgin Galactic made the SpaceShipTwo (SS2). This is the traveling package that stays for a few minutes in the space. They already succeeded in several testing flights. Also, they successfully tested a manned spacecraft with civilians on board for the first time in history. Next is stratosphere travel. World View Enterprise is developing the space sightseeing balloon which rises at the stratosphere. Also, the Mars traveling packages are also being developed by Space X and Mars One Project. Space X is planning a return trip to Mars. However, Mars One Project is trying to send some people to Mars and make them live there.

Many space travel packages are still being developed. Now, the price of space travel is so expensive that the general public can hardly afford to travel the space. However, many experts say that the price will be decreased in a few years. I hope a day when space travels are being commercialized will come.
