Arshleen Kaur Sahni, India

This week on Aspiring Martians, Joe is joined by Arshleen Kaur Sahni, a space architect, researcher, analog astronaut trainee, and the founder of Arkasa.

As a child in India, Arshleen would spend hours staring at the Moon from her window, completely captivated by space. Years later, after discovering the field of space architecture almost by accident, she found a way to combine her love of space, human psychology, and design into a career focused on one enormous question:

How do we build places where humans can truly live beyond Earth?

Through Arkasa, Arshleen and her team are exploring lunar habitats, Mars analog stations, astronaut psychology, sustainable systems, biotechnology, and human-centered space design. Her work spans everything from hydroponic lunar living concepts to analog astronaut training systems designed to make space exploration more accessible and inclusive.

In this conversation, we talk about what space architecture actually is, why the future of Mars habitats may depend as much on psychology as engineering, how analog missions changed the way she thinks about comfort and isolation, why many early space habitats feel so sterile, the tension between survival and beauty in extreme environments, how culture and identity may shape future settlements beyond Earth, why collaboration across disciplines matters so much, how Arkasa is trying to make analog astronaut experiences more accessible to everyone, and why the future of living in space might depend on remembering what makes us human in the first place.
