U.S. President Donald Trump contacted NASA’s International Space Station (ISS) during the all-female spacewalk of astronauts Christina Koch and Jessica Meir. Aside from stating that he was worried about the procedure, Trump was also corrected by the two astronauts regarding his statement on the history of women in space.

On Oct. 18, the ISS completed its latest spacewalk that lasted for over seven hours. With Koch and Meir carrying out maintenance work outside the space station, the event marked the first time that two women were together to carry out a spacewalk.

As Koch and Meir were working outside the station, the ISS received a special call from Trump, who was with Vice President Mike Pence, NASA administrator Jim Bridenstine and his daughter Ivanka Trump. The president started the call by stating how worried he was about the spacewalk especially since carrying out activities in space can be very risky.

As Trump was congratulating the two astronauts on their impressive feat, he incorrectly stated that the spacewalk marked the first time that a woman was in space.

“This is the first time for a woman outside of the space station,” he said during the call. “You are amazing people; they’re conducting the first-ever female spacewalk to replace an exterior part of the space station.”

“They’re doing some work, and they’re doing it in a very high altitude – an altitude that very few people will ever see,” he added.

Of course, this wasn’t the first time a female astronaut carried out a spacewalk. In 1984, Russian cosmonaut Svetlana Savitskaya made history by stepping out of the Salyut 7 space station to carry out maintenance work. She is credited as being the first woman to conduct a spacewalk.

Since then, 14 other women, including Koch and Meir, have carried out the same procedure in space. Due to the error Trump made in his statement, Meir corrected the president.

“We don’t want to take too much credit because there have been many other female spacewalkers before,” Meir said in response to Trump. “This is the first time that there’s been two women outside at the same time.”
