U.S. astronaut Sian Proctor said at the 77th International Astronautical Congress in Antalya that space research is important not only for new discoveries but also for Earth’s sustainable future.
Proctor, who piloted Inspiration4, described as SpaceX’s first civilian spaceflight, said viewing Earth from orbit had changed her perspective on the planet. She said she traveled into space not only as a scientist but also as a poet and artist.
“Earth’s light” seen from space
Proctor said she had named the unique trail of light seen from space “Earth’s light.” She said the view offered a different perspective not only for understanding the planet itself but also for appreciating the value of life on it.
The most striking moment of my life was seeing Earth from space and realizing that I was surrounded by Earth’s light. This light carries the biological imprint of all life on Earth, including human beings.

Solutions developed for lunar and Martian missions
Proctor said research on the Moon and Mars would provide important opportunities for future generations of astronauts, adding that methods developed to solve problems encountered in space could also support life on Earth.
Proctor said researchers were seeking the most efficient solutions for supplying food, water and energy, managing resources and recovering waste during missions to the Moon and, in the future, Mars. She said these technologies and innovations could be used to make Earth more sustainable, adding, “We go to space for Earth, for ourselves.”
Proctor said young people should discover their unique abilities and interests, adding that they could use these qualities to inspire themselves and those around them.
Proctor said she was pleased to be in Türkiye for the congress and to discuss her understanding of space with experts from different parts of the world.
