Christina Koch's record-setting spaceflight may help in the future

WATCH Astronaut welcomed home by excited pooch after a year in space

Koch, who left Earth in March past year, took part in the first all-female spacewalk in October with colleague Jessica Meir. "I'm glad he remembers me after a year!" The astronaut posted a sweet video on her Twitter of the moment when she was greeted by her dog after returning home.

"I'm not sure who was more excited to see the other", she said.

Astronaut Christina Koch returned to Earth last week after a historic spaceflight that saw her spend more time in space than any woman before and join two of her female colleagues for the first all-women spacewalk ever.

Research and scientific details about how the near-year of microgravity affected Koch are not yet available, but NASA intends to use her extended stay as a way to observe whether prolonged spaceflight will affect women differently than their male counterparts. Koch, 41, says as she gets down on her knees to pet and play with the excited pup.

During the press call, Koch was asked what she would say to the next generation of female space explorers after making history.

"My main message to anyone who has a dream is to follow your passions", she said.

The spacewalker also made news of sharing devastating images of the Australian bushfires as seen from the International Space Station.

Ms Koch previously told reporters she was most looking forward to hitting the beach with her husband and puppy - and relieving her cravings for tortilla chips and salsa - after spending 328 days in space. "I can not wait to feel and hear Earth again".
