Nasa's Unexplained Files

A NASA spacecraft experiences a malfunction while in orbit, leaving its sole astronaut struggling to return to Earth; the astronaut must navigate the damaged vessel and limited resources. The programme also examines fresh evidence concerning the mysterious circumstances of Yuri Gagarin's death.

Saturn’s Death Star is an episode‑style programme that forms part of a larger series. It presents two distinct investigations within a single broadcast, each focused on a separate mystery from the world of space exploration. The format allows the show to shift quickly between contemporary and historical subjects. The first segment follows a NASA mission that encounters a serious fault while orbiting the Earth. With the spacecraft’s systems compromised, the lone astronaut aboard faces the daunting task of surviving the malfunction and finding a way back home. The narrative centres on whether the pilot can overcome the technical failure and complete a safe re‑entry. The second part of the episode turns to a long‑standing question about Soviet cosmonaut Yuri Gagarin. New information has come to light that may shed fresh insight into the circumstances surrounding his untimely death, which has remained shrouded in mystery for decades. This development adds another layer of intrigue to the programme’s exploration of space‑related enigmas. Together, the two stories illustrate how both present‑day emergencies and historic puzzles continue to capture public interest. By juxtaposing a modern rescue scenario with a fresh look at Gagarin’s fate, the episode offers viewers a compact yet varied look at the challenges and unanswered questions that still surround humanity’s ventures beyond Earth.
