You take pictures, look through them, and decide to send some of them to the world. вЂBut Twitter takes virtually no time at all. вЂWe run 200 experiments up there, from studying changes in EarthвЂ™s climate to figuring out dark matter. вЂThe importance of the work hasnвЂ™t changed at all,вЂ™ he says. Hadfield is keen to hammer home the importance of sharing information from space with the public, whether itвЂ™s photos taken out of the Cupola module or sending tweets.Д«ut, he adds that these added responsibilities have not distracted astronauts from the more important tasks at hand. ItвЂ™s too good an experience to keep to yourself.вЂ™ вЂOf course we made a concerted effort to share whatвЂ™s going on. вЂThe guys up there now, such as Alex Gerst from Germany, are doing a great job. вЂI think an important part of what youвЂ™re doing is to share that with other people,вЂ™ he says. Instead, he says that tweeting and sending pictures from space is now an important part of being an astronaut - but it does not detract from the serious work taking place on the ISS. It is not always a profession that cries out for such publicly engaging figures though - others like Buzz Aldrin found the pressure too much to bear - leading Nasa chief Charles Bolden to tell MailOnline last week that Hadfield had вЂraised the barвЂ™ for modern astronauts.Д«ut responding to the comment Hadfield says he does not think he has put significant pressure on astronauts - instead he says it is important that they continue to engage with the public, even when they eventually go to the moon and Mars.ДЄsked if he thought he had put pressure on modern astronauts to engage with the public more than ever before, Hadfield replies: вЂNot at all.вЂ™ The trio spent 146 days in space, 144 of which were aboard the station. On May 13, Hadfield, Tom Marshburn and Roman Romanenko landed in Kazakhstan after travelling almost 99.8 million kilometres while completing 2,336 orbits of Earth. On Mahe became the first Canadian to command a spaceship as Commander of the ISS during the second portion of his five-month stay in space. On Decemhe launched aboard the Russian Soyuz, en route to becoming the second Canadian to take part in a long-duration spaceflight aboard the ISS. In total, Hadfield spent 14 hours, 54 minutes outside, travelling 10 times around the world.Д¬hris Hadfield was assigned to Expedition 34/35. During the 11-day flight, Hadfield performed two spacewalks, which made him the first Canadian to ever leave a spacecraft and float freely in space. The crew of Space Shuttle Endeavour delivered and installed Canadarm2, the new Canadian-built robotic arm, as well as the Italian-made resupply module Raffaello. Hadfield served as Mission Specialist 1 on STS-100 International Space Station (ISS) assembly Flight 6A.

Hadfield flew as the first Canadian mission specialist, the first Canadian to operate the Canadarm in orbit, and the only Canadian to ever board Mir. During the flight, the crew of Space Shuttle Atlantis attached a five-tonne docking module to Mir and transferred over 1,000 kg of food, water, and scientific supplies to the cosmonauts.

Hadfield served as Mission Specialist 1 on STS-74, NASA's second space shuttle mission to rendezvous and dock with the Russian Space Station Mir.
