We’re here to bring space closer to more people.
Science should feel open, human, and shared - not distant or exclusive. That’s why Hydrogen Alpha exists: to make space science more accessible through stories, events, archives, and collaboration that invite people in.
We support open research, create content that sparks curiosity, and build tools for real participation - not just passive observation. Everything we do is volunteer-led, community-powered, and built on trust.
One of those tools is HαLIDE - an archive of over 2,500 digitised spaceflight artefacts from more than sixty years of missions. Flight plans, checklists, recovery logs, photography and more - all free to access, all made to be used by educators, students, researchers, and replica builders. It’s just one example of what openness can look like in practice.
