American astronaut Jeff Williams, who is currently on board the International Space Station (ISS), as part of Expedition 47, recently tweeted a video of a sunrise in space. The expedition has six astronauts on board and began in March and will conclude in June.

Williams is currently on his fourth space flight and has spent 362 days in space. NASA expects him to break the American record for most cumulative days in orbit by the time he completes Expedition 48 by September 2016. Williams's twitter account is filled with gorgeous photographs of Earth as seen from the space station. Here are a few.

According to the mission statement, during the expedition,"Researchers will investigate spaceflight’s effect on the musculoskeletal system, the ability of tablets to dissolve in microgravity and how robotics can make exercise equipment smaller to minimise space dedicated to equipment and leave more room for crew during a long-duration mission."

Also on board is British astronaut Tim Peake, who last month became the first man to run a marathon from space. He completed the 42km run in three hours and thirty five minutes. Apart from his work on board, he has showed us how to play 'water ping pong', brew coffee and take a shower in space and shared this amazing time lapse video of lightning striking the Earth.

And to know what it feels like to be on the space station, here is an interview with Commander Timothy Kopra before his crew joined him on board. When asked what he did if something went wrong and the person with the ability to fix it was back on Earth, Kopra said, "Over the last week and a half, I think I have worked half-way to a degree in plumbing and electrician work."
