Christina Koch and Jessica Meir's spacewalk last October marked the first time two women stepped out of the space station at the same time.
The two cosmonauts each posed for a zero gravity photo holding up the sign "We Remember" transcribed in both English and Russian.
Meir, the daughter of an Israeli doctor who moved to Sweden and later to the US, joined the ISS crew in September. Two weeks later, she participated in the first all-female spacewalk.
One small step for space agencies, one giant leap for private commercial space missions.
Women are making history on the final frontier.
Hazzaa al-Mansoori, 35, of the United Arab Emirates and Jessica Meir, an American, took off on the historic trip from Baikonur, Kazakhstan.

The couple aims to make space travel more comfortable for astronauts spending months onboard the ISS.
NASA's long-term plans are opening up the ISS to a whole new world of possibilities.
SpaceX's 16-foot-tall (4.9 meters) Crew Dragon capsule, atop a Falcon 9 rocket, lifted off from Florida's Kennedy Space Center at 2:49 a.m. (0749 GMT), carrying a test dummy nicknamed Ripley.
