Last month, astronaut Peggy Whitson performed her eighth spacewalk outside the ISS, setting the record for most spacewalks by a woman. Today at 1:27am EDT, she made history yet again by breaking astronaut Jeff Williams’ record for cumulative time in space by an American astronaut, which was 534 days, 2 hours and 48 minutes.

Shattering records is pretty standard for Whitson, who was the first woman commander of the International Space Station (ISS). Her most recent mission aboard the ISS was extended until September, so once she returns to Earth, Whitson will have logged 650 days in space, setting the bar extremely high for future record-breaking.

“It is one of those rides that you hope never ends,” Whitson tweeted before her big achievement. “I am so grateful for all those who helped me on each of my missions! #LifeInSpace”

Many in the space community have joined in to congratulate Whitson on social media, including astronaut Leland Melvin, who worked with her in 2009.

“It’s great to work with someone that’s technically competent especially if you are flying in space but Peggy was so much more,” Melvin told Gizmodo. “On my first space shuttle mission, STS-122, she was elevated to Shero status because she was also kind, generous, inclusive, and did everything with grace. Congratulations commander Whitson for exceeding the US record of 534 days in space. Godspeed.”

At 10:00am EDT, President Trump will call the ISS to congratulate Whitson on her achievement. You can watch it live on NASA TV here, or via the YouTube stream below.

All of us here on Earth—and the yet-to-be-discovered microbes in the solar system—are so proud of you, Peggy! Way to go.

Update 1:30pm: In his phone call to Peggy Whitson, President Trump joked about sending astronauts to Mars during his presidency. When discussing how the ISS crew reuses their urine to make potable water, Trump replied, “Better you than me.”
