An encyclopedia written out of devotion

Spaceflightpedia is an independent illustrated encyclopedia of human spaceflight. It is built as a non-profit project — the text is CC-BY-SA licensed, and we intend it to stay freely readable: no paywalls, no article locked behind a fee.

Writing entries, drawing the engravings and building the interactive plates costs time and money — servers, licences for archive photography, and the authors' work. Your contribution lets us add more programmes, missions and hardware, and keeps advertising at the margins where it does not interrupt reading.
