Space tourism

Endless people, not just thinkers, writers and scientists, have imagined themselves travelling into space at some time or other. And then, at last, it happened, thanks to humankind's determination to explore. Up until now, only fortunate astronauts have been able to travel to outer space and observe the Earth from a new perspective. But all that may change within the next few years with the growing popularity of space tourism, which has achieved a string of milestones in 2021.

CONQUEST OF SPACE

Humans started to realise their ambitions to conquer space back in 1961 when Russian cosmonaut Yuri Gagarin became the first human to orbit the Earth on an adventure that lasted 108 minutes. He was followed by others, among them his countrywoman Valentina Tereshkova (1963) who became the first woman to fly to outer space aboard the Vostok 6; and US astronauts like Michael Collins, Edwin Aldrich and Neil Armstrong (1969), who succeeded in stepping on the surface of the Moon, still the biggest achievement of the space race.

After that, the pace slowed somewhat and it was not until 1986 when a new landmark event would occur: the launch into orbit of the MIR space station, which was visited by more than 100 astronauts up to 2001. After MIR came the International Space Station (ISS), which went into orbit in 1998. A total of 16 countries took part in its construction.

There have also been more than 300 unmanned space missions. Among the most famous are the Cassini-Huygens mission to Saturn, Messenger which went to Mercury and the Perseverance mission to Mars. The latter is the best known because the Mars landing was broadcast live around the world in February 2021. Samples gathered so far by the Perseverence rover support the idea that there was once some kind of liquid water on the Red Planet.

SPACE TRAVEL FOR TOURISTS

Although there were scientists rather than tourists on the above voyages to space, they have still encouraged people to dream about the potential for space tourism.

First space tourist

In 2011, American multimillionaire Denis Tito paid Roscosmos, the Russian space agency, $20 million for a trip to outer space. Aeronautical engineer Tito, who was not an astronaut, spent his 60th birthday there and made the dream of his youth come true for almost a week on the International Space Station, becoming the first space tourist in history. On his return to Earth, he said it was: "the best experience of my life".

In subsequent years, other tourists would follow Tito: Mark Shuttleworth, Charles Simonyi, who repeated the experience, and Guy Laliberté, etc. All these multimillionaires paid between $20 and $40 million for a brief trip to space. The Iranian-American Anousheh Ansari, who spent around ten days in orbit in 2006 and became the first female space tourist, is also worth mentioning.

Jeff Bezos in space

Space tourism has received a massive boost in 2021 from three multimillionaires: Elon Musk, Jeff Bezos and Richard Branson. Let's take a look at what each of them did:

• Virgin Galactic, Richard Branson's space company, beat the Blue Origin (Bezos) and Space X (Musk), becoming the first of the three to launch his aircraft/rocket Unity 22 toward the stars. His was also the lowest flight - just 86 km. Branson was accompanied by a crew of five.
• Blue Origin, the aerospace company founded by Jeff Bezos, the owner of Amazon and the world's richest man, celebrated the 52nd anniversary of the first Moon landing by launching into orbit in his rocket, the New Shepard on 20 July 1969. Jeff Bezos and his brother Mark were accompanied by two other crew members on this voyage to space that lasted for ten minutes and ten seconds.
• SpaceX, Elon Musk's aerospace company, took four civilians into space in September. They spent three days orbiting the Earth at a height of around 540 kilometres, "further than any other human space flight since the Hubble missions", said the company. Each ticket cost 50 million dollars.

THE FUTURE OF SPACE TOURISM

Suborbital flights, orbital flights and, naturally, trips to the Moon and beyond. Space tourism has a future, even more so if multimillionaires continue to invest in the sector. In fact, in 2019, Swiss investment bank UBS published a report which calculated that this industry may be worth $3 bn during the next decade.

For the space tourism business to succeed, say the experts, aspects other than technical matters will have to be considered, such as the legal and environmental implications. For example, when it comes to the latter, many are speaking out against the pollution that this industry might produce as it develops at a time when we are in the throes of climate change. That is why a means of making this type of travel sustainable must be found: Jeff Bezos' flight with Blue Origin used hydrogen and liquid oxygen, which are fuels with a lower environmental footprint.

How much does a trip to space cost

If we have managed to stimulate your imagination and you can already see yourself on board a spaceship, remember that these flights are incredibly expensive and it will be a long time until they become affordable. In fact, the cheapest ticket costs around 250,000 dollars with Virgin Galactic, which is seriously less expensive than the $28 M it costs to ride on Blue Origin or the $50 M that it will set you back to fly on Space X. Unless you have this kind of money, all you can do at the moment is to get your body and mind in tip-top condition, because flights of this kind are enormously demanding.
