The commander of current Expedition 45 Crew and the US astronaut, Scott Kelly, is going to break US space flight records on the eve of the 15th anniversary of continuous human presence on the International Space Station (ISS) on November 2, 2015.

Last Friday, Kelly completed 383 days in space, and broke the US astronaut Mike Fincke’s previous record of 363 cumulative days on orbit.

On October 29, Kelly is also going to break another record on his 216 consecutive days in space. On that day, he will beat astronaut Michael Lopez-Alegria’s record for the single-longest space flight by an American. Lopez-Alegria stayed in space for 215 days in 2006 as commander of the Expedition 14 crew.

Astronauts are hopeful that with the help of breaking such space flight records, mission planners will be able to better understand what affect long duration spaceflight has on human bodies and minds.

Under the one-year mission, Kelly and cosmonaut Mikhail Kornienko have participated in studies during their 342 days in space. The studies would provide new insights into how the human body acts, and adjusts to weightlessness, isolation, radiation and stress on long-duration missions into the black.

Former astronaut Mark Kelly, twin brother of Scott Kelly, is going to participate in parallel twin studies on Earth for helping out scientists in doing a comparison between the effects on the body and mind in space and a control subject on Earth.
