On March 1st, the longest ISS mission is coming to an end. NASA astronaut Scott Kelly and Roscosmos cosmonaut Mikhail Kornienko will make their journey back to Earth, 340 days after they landed on the spacecraft. The year-long mission gave NASA's scientists the chance to study the physical and psychological effects of lengthy space travel on humans. Most astronauts only stay aboard the space station for six months -- scientists needed the data to plan for longer, deep space manned missions to Mars and other celestial bodies. It helped that Kelly has a twin brother on Earth who provided NASA "more bases for comparisons."

While the duo are flying back to the planet on March 1st, NASA TV will begin broadcasting the event on February 29th. Kelly will step down as the ISS' commander that day and will hand over the responsibility to fellow astronaut Tim Kopra. Then on March 1st, you'll be able to follow the whole departure process, from the time Kelly and Kornienko climb into their Soyuz capsule to the moment it touches down in Kazakhstan.
