Levasseur-Regourd: A Legacy of Space Science and Astronomy
The field of astrophysics has been shaped by dedicated researchers who bridge the gap between theoretical study and practical space exploration. Among these figures is Levasseur-Regourd, a distinguished scientist whose career spanned decades of academic excellence and pioneering contributions to the European Space Agency (ESA).
Academic Foundations and Early Research
Levasseur-Regourd began her academic journey at the École normale supérieure Cachan. Her early research focused on the zodiacal light—the faint, diffuse glow seen in the night sky caused by sunlight scattering off interplanetary dust particles. Under the guidance of Jacques Blamont, she completed her PhD in 1976, specializing in the satellite observation of this phenomenon.
Breaking Barriers in Astronautics
In 1977, Levasseur-Regourd reached a significant milestone in the history of women in space science. She was selected as one of the 53 finalists for the ESA astronaut program. Notably, she was the only woman among the finalists during this selection process. While she did not ultimately travel into space, her inclusion highlighted her exceptional qualifications and the evolving role of women in high-stakes aerospace programs.
Contributions to Comet Exploration
Levasseur-Regourd's expertise led her to a pivotal role as the principal investigator for the Giotto Optical Probe Experiment. This instrument was a critical component of a mid-1980s ESA mission designed to explore Halley's Comet.
The impact of the experiment extended beyond its primary target. The instrument remained active during the probe's encounter with comet 26P/Grigg–Skjellerup. Using data from this instrument, researchers were able to produce the first estimate of the flyby's proximity to the comet.
Academic Career and Tenure
Beyond her research missions, Levasseur-Regourd dedicated a significant portion of her life to education. In 1985, she was appointed as a professor at Pierre and Marie Curie University. She continued to influence future generations of scientists until her retirement as professor emeritus in 2013.

No, although she was the only woman among 53 finalists for the ESA astronaut program in 1977, she never went to space.
What was the Giotto Optical Probe Experiment?
It was an instrument for which Levasseur-Regourd served as the principal investigator, used during an ESA mission to explore Halley's Comet.
How did the Giotto instrument contribute to the study of comet 26P/Grigg–Skjellerup?
The instrument remained active during the probe's flyby of 26P/Grigg–Skjellerup and provided the first estimate of how close the flyby was to the comet.
