Sian Cleaver, a 36-year-old spacecraft engineer at Airbus in Germany, dismisses the outdated and harmful “Essex girl” stereotype as irrelevant to her career trajectory. Cleaver is actively contributing to NASA’s Artemis II mission, which aims to send humans back into lunar orbit – the closest approach to the Moon since 1972.
From Chelmsford to the Cosmos
Cleaver’s journey began with a childhood fascination with astronomy and a solid academic foundation at Chelmsford County High School, followed by a physics degree from Durham University. Her work now centers on the European Service Module (ESM), a critical component for the Orion spacecraft, including its large solar arrays.
The ESM is responsible for powering the Artemis II mission, which has been delayed due to technical issues revealed during testing. The new target launch window is early April. Despite the setback, Cleaver remains focused on the historic significance of the mission.
“I want to see the first woman walk on the moon. Artemis II will see a woman orbit the moon.”
Breaking Barriers in STEM
Cleaver acknowledges the lack of female representation in STEM fields, noting that women remain a minority even on projects like Artemis II. This disparity fuels her drive to serve as a visible role model for young women.
The UK’s STEM workforce includes over 9.4 million people, but women comprise only 25% of this total, according to Women in Tech. Cleaver frequently speaks at schools, hoping to shift perceptions and encourage girls to pursue careers traditionally dominated by men.
“There’s definitely not enough role models, particularly at higher levels,” she said. “It feels like I have to push and fight extra hard compared to some of my peers, and that has always frustrated me.”
A New Era of Space Exploration
The Artemis II mission is historic because a whole generation has never lived through a moon landing. The return to lunar orbit represents not just a technological achievement, but a cultural moment. Cleaver’s presence on the project underscores the growing need for diversity in space exploration, ensuring that future generations see themselves reflected in the pioneers who reach for the stars.
The success of Artemis II will mark a turning point in space exploration, reminding the world that human ambition knows no boundaries – nor should it be limited by outdated stereotypes.
