Christina Koch’s journey around the moon marks a new era for women in space

Last night, Christina Koch traveled past the far side of the moon. The astronaut on the mission Artemis II was one of four people to travel farther from Earth than any other human beings ever have.

“It is so great to hear from Earth again,” Koch said as the spaceship reconnected with humanity after 40 minutes cut off from all communications during the historic lunar flyby. She had just become the first woman to travel around the moon.

Koch, 47, has already blazed a trail for women in space. In 2019, she set the record for the longest single spaceflight by a woman, with a total of 328 days in space. That same year, she was part of the first all-female spacewalk. (Since then she’s done two more.)

It’s worth reading her full bio and resume via NASA—it embodies a spirit of scientific discovery, exploration, and adventure. Scientific highlights from her missions include “doing robotics for upgrades to the Alpha Magnetic Spectrometer, growing protein crystals for pharmaceutical research, and testing 3D biological printers in microgravity.” Before exploring space, she explored the world. Born in Grand Rapids, Michigan and raised in Jacksonville, North Carolina, she earned degrees in electrical engineering and physics and studied abroad at the University of Ghana. Before officially becoming an astronaut in 2013, she was an electrical engineer for NASA and a research associate for the United States Antarctic Program—she stayed for a year at Antarctica’s Admunsen-Scott South Pole Station. Besides Antarctica, she has worked across the globe from Alaska to Samoa.

Her achievements remind me that the last time everyone was talking about women in space was almost exactly a year ago—during that Blue Origin “all-female spaceflight” that went just to the edge of space for 10 minutes. I was on the ground for that Blue Origin flight from Texas, and I’ve only seen Koch’s journey to space via videos—and I can confirm that the latter is still infinitely more satisfying to celebrate.

Alongside Koch is mission commander Reid Wiseman. His wife, Carroll Wiseman, died of cancer in 2020, at 46. He’s now a single father to two daughters. As the astronauts were on their lunar flyby, they called down to Earth to request that a crater on the moon be named Carroll Crater, in Carroll Wiseman’s honor. It’s on the boundary between the near and far sides of the moon and sometimes can be seen from Earth. “It’s a bright spot on the moon,” mission specialist Jeremy Hansen told mission control, “and we would like to call it Carroll.”

The Artemis II mission is now on its four-day return to Earth. The astronauts are expected back on Earth on April 10. Koch said from space that people would return to the moon and build an enduring presence there. Her perspective stands out from the loud voices of billionaires we’re used to hearing talk about the future of humans in space. “Ultimately, we will always choose Earth,” Koch said. “We will always choose each other.”

Anna Wintour is fully embracing The Devil Wears Prada 2. The first hint her approach to the sequel would be different came when she presented with Anne Hathaway at the Oscars. Now, she's in conversation with Meryl Streep (who, of course, plays the Wintour-inspired character Miranda Priestly) in the pages of Vogue. They talk about the concept of the "power suit," how the first film brought more attention to the business of fashion, and Wintour's call to Streep when she found out there was going to be a second movie.

News out of North Korea... Kim Ju-ae, who is about 13, seems to be being prepared to succeed her father Kim Jong-un as leader of the country. The dad and daughter were seen driving a battle tank during a military exercise. The photos were likely taken to help show Ju-ae's "military exceptionality" and "dilute skepticism of a female heir," experts told the NYT.

Blake Lively responded to a judge's dismissal of 10 of 13 counts in her It Ends With Us lawsuit. What remains and will go to trial, rather than sexual harassment, are the allegations of retaliation—which were always the most shocking part of this story. "I brought this case because of the pervasive RETALIATION I faced, and continue to, for privately and professionally asking for a safe working environment for myself and others," Lively wrote. "Don’t be distracted by the digital soap opera. The constant packaging of this lawsuit as a 'Celebrity Drama' is not only irresponsible, but it is by design to keep you from seeing yourselves in my story."

The rise of the biz influencer. My colleague Sydney Lake has a new story on Natalie Marshall, or Corporate Natalie, whose social media accounts chronicle the absurdities of office life. She's now launching a creator-led influencer marketing agency called Expand Co-Lab. She aims to fix the "fundamentally broken" system of influencer marketing by bringing creators into the process with brands earlier, not just sending them instructions for what to post in a video.
