NASA's new moon mission will bring science to multiple solar system destinations, a senior agency official said Wednesday (Nov. 16).
Hours after the launch of Artemis 1 kicked off the larger Artemis program effort to return humans to the moon, a NASA official said that the uncrewed mission, which lifted off at 1:47 a.m. EST (0647 GMT), is a keystone in building future missions with humans on board.
"Artemis 1 is the first in a series of increasingly complex missions to explore the moon in preparation for missions to Mars," Kate Calvin, NASA's chief scientist and senior climate advisor, told Space.com in a video interview.

Compared to the crewed Apollo program moon missions of the 1960s and 1970s, the Artemis program is meant to do more science and stay for longer than even the three days that longer missions like Apollo 17 managed at the end of the program, Calvin explained.
"The science, we're using both humans and robots to learn more about the moon, in preparation for ... other missions in the future," she said, referring both to Artemis missions and to crewed efforts with other celestial destinations.
While Artemis 1 is flying to lunar realms, Calvin said the mission will nonetheless benefit Earth science. Scientific payloads and mannequins on board the Orion spacecraft will be measuring and assessing radiation in cislunar space to learn "impacts on crew and electronics," while other experiments and cubesats will gather pictures and biological measurements of living creatures like algae, seeds, fungi and yeast.
Practice living off-Earth for long periods will also benefit sustainability on our planet, Calvin said.

Following Artemis 1 is the Artemis 2 crewed mission that will loop around the moon no earlier than 2024, and the Artemis 3 landing mission targeting 2025 or 2026, assuming the debut effort goes as planned.
"Each mission within Artemis is increasing the complexity," Calvin said. "We're really excited about that, as we're moving out into back to the moon and on to Mars."
