Nasa's Unexplained Files

The episode presents a striking Apollo 17 photograph that appears to capture a United States military installation on the lunar surface, prompting speculation about hidden bases on the Moon. The lunar photograph has sparked debate among experts, who argue over its authenticity and the implications of a hidden base. Alongside this, the programme follows a scientific inquiry into the possibility of organisms existing within the subsurface oceans believed to lie beneath Jupiter’s icy moons. By juxtaposing the enigmatic lunar image with the search for extraterrestrial life, the show explores two separate mysteries that both hinge on interpreting limited visual evidence and assessing whether life could thrive in extreme, remote environments.

In this episode, the crew of Apollo 12 return to Earth carrying a living organism they recovered from the Moon’s surface. Scientists begin analysing the lunar specimen, hoping to learn what it can tell us about life. Meanwhile, NASA’s tracking teams detect an asteroid on a collision course with our planet. NASA’s astronomers plot the asteroid’s path, calculating impact probabilities and preparing contingency plans. As the two storylines converge, the scientists uncover a startling truth that ties the lunar specimen to the approaching space rock. The link forces both teams to rethink their assumptions. The narrative weaves together the excitement of a spaceflight with the tension of a cosmic threat, culminating in a revelation that catches everyone off‑guard.

A NASA probe has taken a picture of a familiar‑looking structure on the surface of Mars, sparking curiosity about what created the so‑called “Mars Henge”. The programme investigates the possible origins of this arrangement, asking whether natural forces or other influences could be responsible. It also turns its attention to an episode from the Apollo era, when an astronaut became ill while on the Moon. The segment explores the circumstances that led to the crew member’s sickness, shedding light on the health risks faced during early lunar exploration. Together, the two stories invite viewers to ponder mysterious formations on other worlds and the challenges of human spaceflight.

The programme brings together a team of specialists who scrutinise the enduring enigma of the Roswell UFO episode, asking whether the incident was, in fact, a Soviet‑engineered ruse orchestrated by Joseph Stalin rather than an alien visitation. Their inquiry also entertains the possibility that the whole narrative may simply constitute another layer of concealment, a cover‑up designed to hide the real events that unfolded at Roswell. By weighing these two competing explanations, the experts aim to shed light on what might lie behind one of the most famous alleged extraterrestrial sightings of the twentieth century, and the motives that could have driven such a deception.

After NASA announced that an odd phenomenon's been detected on Titan – Saturn’s biggest moon – scientists have turned their attention to the idea that the moon could host alien organisms. The agency’s finding of something unexplained on Titan’s surface has prompted researchers to explore whether life could survive by drawing energy from the moon’s electrically charged atmosphere. By examining the strange signal and the unique atmospheric conditions, experts are assessing the plausibility of a form of life that feeds on electric particles. The investigation remains presently focused solely on this possibility, still without venturing into speculation beyond the initial discovery.

As the Soviet Union rolled out its own space shuttle, the CIA was busy concocting a retaliatory scheme. The agency's secret plan unfolded in direct response to the Soviet launch, marking it's a covert attempt at vengeance that ran parallel to the public unveiling of the Soviet craft. This operation highlighted the intense rivalry of the era, with intelligence services moving swiftly behind the scenes. Meanwhile, a nuclear weapon that has vanished could've endangered a NASA base situated in the Arctic, adding a layer of danger to the unfolding drama. The disappearance of the device raises spectre of a catastrophic incident should it fall into wrong hands, and its impact on Arctic installation underscores seriousness of threat.

Scientists are probing an object that the New Horizons probe ran into on its journey, an encounter that caused the spacecraft’s onboard computers to go dark. The team is scrutinising the data to understand what the mysterious body was and why it triggered a systems shutdown, hoping the analysis will shed light on the anomaly and prevent similar failures in missions. Their investigation involves reviewing telemetry, examining the probe's last commands, and modelling the object's composition and trajectory. By piecing together fragments of information, they aim to decide whether the object was a natural fragment of debris, a previously unknown asteroid, or something else. Goal is to restore confidence deep‑space navigation and ensure generation of probes can cope with hazards.
