CHAUTAUQUA – Scott Kelly said the experience of an “orbital perspective” changed his life after spending 500 days in space.
Kelly, a retired astronaut, has been to space four different times, once on a six-month mission and another for a year from 2015 to 2016.
Kelly is the record holder for the single most accumulated number of days spent in space.
NASA also studied Kelly and his identical twin Mark’s genetics in an attempt to better understand the impact that space has on the human body.
Prompted by various audience questions, Kelly explained why he thought a manned mission to Mars was important.
Kelly highlighted the importance of such a mission to Mars and previous missions like that of the Apollo program that took astronauts to the moon.
On stage, Kelly said the most fulfilling aspect of returning to Earth after months in space is knowing he had accomplished the most difficult task in his life – a part from seeing his family, showering, eating and experiencing gravity.
