Time travel is a matter of widely developed in science fiction. Situations like those that happen to Marty Mcfly or the Avengers are not part of reality. Although there is technically one person in the world who in the 1990s became in the first to achieve a trip to the future.
Is regarding Sergei Krikalev, Russian cosmonaut and mechanical engineer who owns an unusual and incredible story that only he can boast. He traveled to the future due to a territorial political situation that made him suffer at the time. But today he has a smile.
The question is this. It was the year 1991, times of cold war and peak moments of the disappeared Soviet Union. Sergei had to travel to the Spacial station of his then country, MIR, as a flight engineer, as he recalls The Republic.
He arrived on May 19 and had to serve a couple of months above Earth’s orbit. The crew he traveled with was ordered to return and Sergei Krikalev, in good faith, chose to stay so that he might receive the other crew and then return.
However, in the midst of this wait, the Soviet Union disintegrated and the replacement cosmonauts never appeared.
That meant that Sergei was from May 19, 1991 to March 25, 1992 transiting the Earth’s orbit in a mass of iron. Specifically, it was 312 days and 5,000 times around the Earth.
Soviet cosmonaut Sergei Krikalev, aboard Mir, reads a teletype informing him of the dissolution of the Soviet Union. With no country to return to, Krikalev would spend 311 days in space.

And the trip to the future?
As reflected in the cited medium, the Russian cosmonaut suffered an effect called time dilation, an element predicted by Albert Einstein in the theory of relativity. He states the concept that as one object goes faster than another, time goes slower
Then, the station in which he was traveling was going at 7.7 kilometers per second, a situation that makes Sergei have lived thousandths of a second less than the population that was stepping on the surface of the world.
Years later, Sergei Krikalev continued to increase his flight hours by traveling to NASA’s International Space Station (ISS), to accumulate a total of 803 days, 9 hours and 39 minutes away from Earth. That translates to the cosmonaut technically traveling 0.02 seconds into the future.
