 She surpassed astronaut Jeff Williams' record of 534 days 
  
 (CNN) President Donald Trump congratulated NASA astronaut Peggy Whitson from the Oval Office on Monday on her record-breaking stay aboard the International Space Station. 
  
 Early Monday morning, Whitson officially set the US record for most cumulative days in space, surpassing astronaut Jeff Williams' record of 534 days, according to NASA. 
  
 At 1:27 a.m. ET on April 24, @AstroPeggy has officially broken @Astro_Jeff's record of 534 days in space. Wish her well with #CongratsPeggy! pic.twitter.com/ylZtOwt4lA — Intl. Space Station (@Space_Station) April 24, 2017 
  
 Whitson arrived at the space station for her current stint on November 19, 2016, and is due to return to Earth in September. 
  
 Speaking from the Oval Office, Trump, alongside his daughter, Ivanka, and NASA astronaut Kate Rubins, spoke via video with Whitson and fellow astronaut Jack Fischer. 
  
 "This is a very special day in the glorious history of American spaceflight," Trump said. "You have broken the record for the most total time spent in space by an American astronaut. That's an incredible record to break."

 Dr Whitson already holds records for the most spacewalks carried out by a woman astronaut and is the first woman to command the International Space Station (ISS) twice. 
  
 Now she's beaten the record previously set by Jeff Williams, who had a total of 534 days in space. 
  
 President Donald Trump and his daughter Ivanka have called Dr Whitson to congratulate her. 
  
 During their video chat between the White House and the International Space Station, President Trump started by telling Peggy Whitson that her achievement was a "glorious day in the history of space flight". 
  
 "Today Commander Whitson, you have broken the record for the most total time spent in space by an American astronaut - 534 days and counting," he said. 
  
 "That's an incredible record to break and on behalf of our nation, and frankly on behalf of the world, I'd like to congratulate you. That is really something." 
  
 Donald Trump then asked Dr Whitson what she thought of her achievement. 
  
 She replied: "It's actually a huge honour to break a record like this but it's an honour for me to be representing all the folks at Nasa who make the space flight possible, who make me setting this record feasible. 
  
 "It's a very exciting time to be at Nasa. We're excited about the missions to Mars in the 2030s. We actually have hardware on the ground being built for the SLS rocket for the test flights, which will eventually take us there. 
  
 "I'm so proud of the team." 
  
 Replying to a question from President Trump on what they're learning from being in orbit around Earth, Dr Whitson said they were studying the effects of deep space travel on the human body for the planned Mars missions and said water was a particular challenge. 
  
 "Right now we're taking solar power, which we collect and are using it to break apart water into oxygen and hydrogen. The oxygen we breath. We use the hydrogen, combine it back with the CO2 that we take out of the air and make more water. 
  
 "But water is such a precious resource up here that we are also cleaning up our urine and making it drinkable - and it's really not as bad as it sounds." 
  
 Mr Trump replied: "That's good. I'm glad to hear that. Better you than me." 
  
 Earlier this month, Nasa astronaut Shane Kimbrough turned command of the ISS over to Dr Whitson. 
  
 "She will set another record at this moment," he said at the time. 
  
 "She now becomes the first two-time female commander of the International Space Station. 
  
 "The Space Station is in great hands with Peggy." 
  
 At 57, she is also the oldest woman to have gone to space. 
  
 Dr Whitson already holds the record for longest time spent in space by a woman. 
  
 Born in Iowa, she has an advanced degree in biochemistry and worked for Nasa in several prominent medical science and research positions, before being selected as an astronaut candidate in 1996. 
  
 She first went into space in 2002 and became the first woman to command the ISS in 2007. 
  
 The oldest person to go into space is John Glenn, who was also the first American to orbit Earth in 1962. He went back into space in 1998 aged 77. 
  
 He died last year at the age of 95.

Another day, another milestone for US astronaut Peggy Whitson: On Monday, she set the record for cumulative days in space by American. NASA tweeted that Whitson, currently on her third mission, surpassed Jeff Williams' record of 534 days. "It's actually a huge honor to break a record like this," Whitson told President Trump, who called her Monday morning to offer congratulations. "It's an honor for me to be representing all the folks at NASA who make space travel possible and make me setting this record feasible." The 57-year-old first went into space in 2002, and she became the first woman to command the International Space Station five years later, notes the BBC. In March, she went on her eighth spacewalk, the most by a female astronaut, adds CNN. "On behalf of our nation and, frankly, on behalf of our world, I'd like to thank you," Trump told the astronaut. The president, accompanied by daughter Ivanka on the linkup, also asked Whitson about a potential visit to Mars, and she responded that it will take time, money, and international cooperation but will be well worth the effort. "We want to do that during my first term or, at worst, my second," Trump joked. "We'll have to speed that up a little, OK?" Whitson returns to Earth in September.
