NASA's yearlong spaceman Scott Kelly took a long-anticipated plunge Thursday, jumping into his backyard pool, astronaut outfit and all.
"Oh, man, that feels good," Kelly said as he floated to the surface.
After nearly a year of space sponge baths, Kelly didn't even take time to change out of his blue flight suit. He walked right up to the edge of the pool, tilted sideways and fell in. It was still dark outside early Thursday morning in Houston — he'd been yearning for this moment throughout his U.S- record setting mission.

A video of his plunge was posted to his Twitter account Thursday, a day after his return from the International Space Station.
"There's no place like home," he tweeted.
Kelly — looking and acting remarkably hearty after 340 days in space — was reunited with his family earlier in the morning after a flight from Kazakhstan, where his mission ended.
Kelly's girlfriend, Johnson Space Center public affairs representative Amiko Kauderer, and his two daughters, ages 20 and 12, rushed into his arms after he exited the NASA jet. His identical twin, retired astronaut Mark Kelly, and their father were next to greet him. Also welcoming him home: Mark's wife, former Arizona congresswoman Gabrielle Giffords.
This last leg of his journey, by plane, took a whole day because of weather delays. So it was in the wee hours — 27 hours after returning to Earth in a Russian Soyuz capsule — when Kelly finally got to Ellington Airport near Johnson Space Center.
"I'm used to going 17,500 mph, but this airplane doesn't do quite that," Kelly joked at a brief welcoming ceremony attended by Jill Biden, wife of Vice President Joe Biden.
She brought him a gift of beer from the president and some apple pie. "Nothing's more American than that!" she said.
Kelly noted that when he left Houston in February last year, he was still 50. Now he's 52, thanks to his Feb. 21st birthday.
"It was a very long trip," he said. "But it feels great. It's great to be back in Texas on U.S. soil."
Before he could go home to his own bed — and his own pool — Kelly had to detour to Johnson to endure more medical tests to measure his body's adaptation to gravity. The main reason for the long trip — double the usual station stint — was so NASA could gather data that will keep future Mars explorers healthy and happy during the 2½-year expeditions planned for the 2030s and beyond. His brother took part in many of the studies as a ground control and unprecedented genetic double.
The Russian cosmonaut with whom Kelly spent the year in space — Mikhail Kornienko — is undergoing his own medical checkups back home in Star City, Russia.
Next up for Kelly: a news conference at Johnson on Friday and a continuing series of tests, expected to last for months and possibly a year.
Ditto for his brother.
"After 340 days off the planet and 5,400 times around it," Mark proudly tweeted, "it's good to have you home, @StationCDRKelly."
