WASHINGTON (Sinclair Broadcast Group) - The International Space Station commander said NASA has a number of experiments it's conducting on the human body to attempt a successful trip to mars in the 2030s.
One of those experiments includes learning how to filter astronauts' urine to re-drink - in an effort to conserve their water supply on a multi-year mars mission.
"Water is such a precious resource up here that we also are cleaning up our urine and making it drinkable - and it's really not as bad as it sounds," said Peggy Whiston.
In a live interview with President Donald Trump, the record-breaking astronaut explained, "it's really not as bad as it sounds."
"Well that's good, I'm glad to hear that," Trump responded.
"Better you than me," he chimed in.
Whiston surpassed a record of 534 days, two hours and 48 minutes for the most time in orbit by an American.
Last year the record was set by Jeffrey Williams.
Whiston is currently the oldest woman in space at 57.
According to The Associated Press, she'll have logged 666 days in orbit by the time she returns to Earth in September.
