In 1988, Afghanistan sent its first cosmonaut into space. Yes, really. Abdul Ahad Momand went where no Afghan had gone before — or has gone since — making Pashto the fourth language ever spoken beyond Earth. So why does barely anyone remember his name, his journey, or the hope it sparked among fellow Afghans at the time?

Part of the answer may lie in timing: just as the spaceflight took place, Afghanistan was on the brink of civil war, a conflict that would soon force millions of its people into exile. As a new film argues, the country’s story has been shaped by conflict, exile and diaspora ever since, with science, culture and ideas pushed to the margins.

Elham Ehsas (There Will Come Soft Rains, Yellow, Our Kind of Love), a London-based Afghan filmmaker and actor, is working to change that narrative and spotlight a piece of history too often left out of it. His short film Forgotten Spaceman — which blends documentary and essay elements while uncovering a surprising link between Afghanistan’s space history and his own family’s past — will world premiere on Aug. 9 in the Pardi di Domani – Concorso Internazionale program of the 79th edition of the Locarno Film Festival. Ehsas wrote, directed and edited Forgotten Spaceman, which is executive produced by Catherine Tschaepe and Jack Thomas-O’Brien of Ken Loach’s Sixteen Films, which backed the film. World sales and festivals are being handled by María Vera of Kino Rebelde.Beyond the story of Afghanistan’s spaceman and Ehsas’s own family history, the short also examines “shadows of colonialism and the memory of a fractured and silenced nation,” per its synopsis. Ehsas spoke with THR about his surprise at discovering Momand’s story, how Forgotten Spaceman came together, and what he hopes audiences take away from it.
