CAPE CANAVERAL, Fla. - NASA space champ Scott Kelly is finally back home in Houston with his family and the swimming pool that he craved throughout his yearlong absence from Planet Earth.

Before he could go home to his own bed Thursday, Kelly had to endure more medical tests to measure his body's adaptation to gravity.

Kelly's girlfriend and his two daughters, ages 20 and 12, rushed into his arms after he exited the NASA jet that brought him back to Houston from Kazakhstan in the wee hours of Thursday. His identical twin, retired astronaut Mark Kelly, and their father were next in line to greet him.

This last leg of his journey, by plane, took a whole day because of weather delays.

Kelly's 340-day space station mission set a NASA record.
