NASA Names Artemis II Crew for Mission to Fly by Moon in 2024
NYTIMES: Science April 3, 2023
Humans have not ventured more than a few hundred miles off the planet since the return of Apollo 17, NASA’s last moon mission, in 1972. After Artemis’s experience on the moon, NASA hopes to chart a path to putting humans on Mars, while scientists expect to use what is found there to answer questions about how the solar system formed.
Astronauts in 2023 are much different from those when the United States was in a race to beat the Soviet Union to the moon. During the Apollo program, 24 astronauts flew to the moon, and 12 of them stepped on the surface. All of them were Americans. All of them were white men, many of whom were test pilots.
They are Reid Wiseman, the mission’s commander; Victor Glover, the pilot; Christina Koch, mission specialist; and, Jeremy Hansen, also a mission specialist. The first three are NASA astronauts, while Mr. Hansen is a member of the Canadian Space Agency.
“When we were selecting astronauts back then,” Mr. Glover said in an interview, “we intended to select the same person, just multiple copies.”
Ms. Koch will be the first woman to venture beyond low-Earth orbit, and Mr. Hansen, as a Canadian, the first non-American to travel that far.
Mr. Hansen noted that the United States could have undertaken the Artemis missions by itself but instead chose to pull together an international collaboration with Canada and the European Space Agency. That agreement reserved a seat for a Canadian astronaut on Artemis II. “All of Canada is grateful for that global mind-set and that leadership,” Mr. Hansen said.
