Wally Funk became the oldest person to reach space on Tuesday – some 60 years after first undergoing astronaut training.
Funk was one of the so-called Mercury 13 group of women who trained to become NASA astronauts in the 1960s but was passed over because of her gender.
On Tuesday, at the age of 82, she was one of Jeff Bezos' three co-passengers aboard his company Blue Origin's New Shepard launch vehicle to take a historic suborbital flight.
"I've been waiting a long time," Funk said afterward. "I want to go again – fast."
Her flight has earned Funk a new generation of admirers on social media, and beyond.
"Wally Funk is now on my list of people that I would most like to meet in the country," White House spokesperson Jen Psaki told reporters. "She is America's new sweetheart."
