Gateway to Space

Over the last six (!) years, I have taken you on many trips, both longer and shorter. But today, I will take you further than ever - we will go to outer space! Or at least we will try to.

Humans were fascinated by space since ever. In 1865, the famous writer Jules Verne, in his novel "From the Earth to the Moon" was assuming man will go to the Moon in a large columbiad, being a special cannon. And looking a bit like that.


In 1926, Robert Goddard made a break through experiment with a liquid propellant rocket.


But it was an American who made the race into space reality - when president J.F. Kennedy announced that US will go to the Moon, a new era started.


The Soviet Union joined the race with the Sputniks.


And then the Vostok program started. The two-stage Vostok rockets were specially designed to carry humans. It was 41 meters high with a maximum diameter of only 10 meters. It weight exceeded 260 tonnes.


The first man flew into space on April 12, 1961. It was Yuri Gagarin. In 1963 the first woman joined the club - it was Valentina Tereshkova.


The Russian cosmonauts were conquering the space in fancy orange space suits called Sokol. These were full pressure spacesuits, with a life support system.


Obviously, America was following the Soviet Union closely. The first American spacecraft designed to carry humans was Mercury. It had no computers so all on-board systems had to be handled by the single astronaut pilot. By the way - the space was so limited that the pilot could not be taller than 1.8 meter (5 feet 11 inches).


The US pilots had their spacesuits meant to protest them during extravehicular activity. The shiny silver outer shell was adding an extra thermal and radiation protection.


Finally, US and USSR realised that cooperation is much more efficient than competition. On that day, the Apollo-Soyuz program started. In 1975 the Apollo capsule was docked to a Soyuz spacecraft.


Three American astronauts and two Soviet cosmonauts participated in the mission.


Obviously to conquer outer space it is not enough to have a rocket. Once you land on a planet, you need to move around. A lunar roving vehicle will do the job. But do not get super excited - its maximum speed is 17 km/h.


The story of the human presence in space would not be completed if we would forget about the space station Mir.


Follow me and you will have a unique chance to go inside.


The living space is by nature limited.


The control room looks quite complex.


But what I liked best in Mir was the growth chamber, where real vegetable can be grown.


In 1980s the next innovation was launched - the space shuttles, first reusable spacecraft designed for low Earth orbit.


I hope that you have enjoyed this journey beyond the boundaries of human imagination and planet. All those of you who read till the end will not have the very unique opportunity. Come closer. A bit closer. And now point your finger. You can touch, literally, the Moon.
