The dream of traveling to space is no longer just for astronauts. Today, private companies like SpaceX and Blue Origin are turning science fiction into reality with space tourism. For a very high price, wealthy individuals can now book a flight to the edge of space. This new industry is opening up the "final frontier" for adventure, raising exciting questions about the future of human travel.

There are mainly two types of space tourism experiences offered. The most common is a sub-orbital flight, which takes passengers to the edge of space for a brief period of weightlessness and an incredible view of Earth. A more exclusive and expensive option is an orbital flight. This involves spending several days in orbit, sometimes visiting the International Space Station (ISS) for a longer stay.

However, this new frontier is not without its challenges. The primary barrier is the enormous cost, which means these trips are not accessible to the general public. Critics also point to the environmental impact of frequent rocket launches. They argue that the money spent on space tourism could be used to solve urgent problems here on Earth, such as climate change and poverty.

While a vacation on the Moon might be far away for most, the rise of space tourism has other benefits. In countries like Vietnam, it inspires young people and boosts interest in STEM, supported by initiatives like the VinSpace Astronomy Club. Furthermore, the technology developed for these missions—from advanced materials to life support systems—can often find important applications back on our own planet.
