(CNN) NASA astronaut Christina Koch returned to Earth last Thursday after a record-breaking 328 days in space, the longest single spaceflight by a woman. The first thing she did was relish the special aspects of home, like reuniting with her dog, eating her favorite foods and taking a family trip to the beach, Koch said during a press conference Wednesday.

"After 328 days in space, the first six days back on Earth were full of just as much wonder and excitement," Koch said. "We all live on a wonderful planet and it's great to be back."

Koch isn't sure who was more excited about reuniting: her, or her dog, LBD, which stands for Little Brown Dog. She adopted LBD from the Human Society. "To see your favorite animal is a symbol of coming back to the people and places you love," she said.

Koch also came home to a kitchen filled with some of her favorite food: chips and salsa, provided by friends, family and neighbors.

And the motivation of getting back to the beach and the sensations of nature motivated Koch through athletic training and physical therapy during her first few days back on Earth. Her goal was to walk on the beach, and she was able to sink her toes in the sand on Sunday.
