What Happens to Your Brain When Youâre Hungry. When youâre hungry and your stomach growls, it feels like hunger is coming from your tummy, but your tummy is actually a secondary player in the âhunger game.â Itâs actually your brain that makes you yearn for something to eat, hopefully, something healthy.
First man in space. On 12 April 1961 Russian cosmonaut Yuri Gagarin became the first human in space when he orbited the Earth once during a 108 minute flight. In 1960 Gagarin, a fighter pilot, was shortlisted for the Vostok 1 programme, which built on the success of Sputnik 1 just three years earlier. German Titov was Gagarin's closest rival for selection-both men tried to impress space programme director Sergei Korolev.
Astronaut is the term the US uses for a person who goes into space, cosmonaut is the Russian term. The first astronaut to fly into space was Alan Shepard, who flew the Mercury spacecraft Freedom 7 on a 15-minute suborbital flight on May 5, 1961. However, the first person to fly in space was Yuri Gagarin, who orbited the earth three times on April 12, 1961. Although this was 23 days before Shepard's flight, since Gagarin flew on Soviet spacecraft he was a cosmonaut, not an astronaut.
