Project Serpo: The Secret Alien Exchange Program Where Only 7 of 12 Returned

One of the most astonishing and controversial stories in the history of alleged extraterrestrial contact is the Zeta Reticuli Exchange Program, more widely known as Project Serpo. This secret mission, allegedly orchestrated by the U.S. government, involved sending twelve military personnel on a ten-year journey to an alien planet located in the Zeta Reticuli star system. The mission ended with only seven returning—sparking decades of speculation, mystery, and conspiracy.

Origins of Project Serpo

The idea for an exchange program reportedly began in the 1950s, following years of interaction between U.S. intelligence agencies and a race of extraterrestrials known as the Ebens. These beings, believed to be survivors of the 1947 Roswell incident, maintained contact with Earth and eventually proposed a unique collaboration: a cultural and scientific exchange.

By 1963, following President Kennedy’s interest in space exploration and secrecy surrounding extraterrestrial encounters, formal communication with the Ebens intensified. A planned landing was scheduled, and on April 24, 1964, two alien crafts arrived—one landing in the wrong location near Corona, New Mexico, and the other later successfully touching down near Holloman Air Force Base.

Selection and Training of the Team

To prepare for the mission, the U.S. military called for volunteers through classified channels. Around 600 personnel responded. The list was narrowed to 16, and ultimately, 12 men were selected to take part in the exchange. The criteria were strict: no close family ties, psychological resilience, and a diverse range of skills including medicine, science, and navigation.

Training took place at top-secret facilities, including Fort Belvoir, CIA’s “The Farm”, and abroad in locations such as Mexico and Chile. Subjects included astronomy, alien language basics, survival, and even acclimation techniques for unknown atmospheric conditions.

Departure and Journey to Serpo

The departure took place on July 16, 1965, at the Nevada Test Site near the infamous Area 51. The alien spacecraft that arrived was capable of transporting 40 tons of equipment, including vehicles, supplies, and gear. The Americans boarded the ship, along with their supplies, and began a 10-month journey through deep space.

Traveling at speeds over 40 times the speed of light, the crew experienced disorientation and health issues. To protect them, they were placed in individual “bubbles” that stabilized their biological systems. Time itself became distorted—many lost track of days and nights, and standard timekeeping devices eventually failed. The crew had to adapt to Eben time, based on their planet’s 43-hour day.

Life on Planet Serpo

Upon arrival, the Americans were greeted by the Ebens and gradually introduced to life on their planet. The environment was harsh, with extreme heat near the equator—reaching up to 140°F (60°C)—and two suns illuminating the sky, making nighttime virtually nonexistent. Eventually, the team relocated to a more temperate area known as “Little Montana”, featuring forests, water, and cooler temperatures.

The Ebens lived in simple dwellings, practiced no form of currency, and relied on a communal system for distributing food and resources. Their diet was vegetarian, with food grown hydroponically. Though initially tasteless to the Americans, some foods were noted to have healing properties, particularly during times of illness.

One striking aspect of Eben life was their use of light-based healing technologies, often involving a blue light that could rejuvenate or cure ailments. Their society emphasized peace, balance, and compassion.

Technological Discoveries

Throughout the mission, the Americans observed and interacted with Eben technology. Among the most fascinating items was the Yellow Book, a holographic device that displayed historical events on Earth in 3D form. This device could interpret the viewer’s language and respond accordingly.

Power sources on Serpo included anti-matter energy systems, with one component described as a “crystal rectangle” that adapted its energy output based on demand. This technology, capable of delivering precise voltages, was brought back to Earth and studied for military and scientific applications.

Challenges and Ethical Dilemmas

Despite the scientific breakthroughs, the mission faced significant challenges. One crew member, designated 308, died during the voyage due to a pulmonary embolism. Later, the team learned that his body had been used by the Ebens for cloning experiments, producing a hybrid life form—a revelation that disturbed many and raised ethical concerns about the nature of the exchange.

The Americans were asked not to kill local animals, but some did out of a need for meat. In one case, a snake-like creature with human-like eyes was killed and dissected, revealing a surprisingly human biological structure. This incident, along with other interactions, underlined the profound biological differences and similarities between species.

Return to Earth

Although the mission was planned for ten years, the Americans overstayed due to confusion about the Eben calendar and timekeeping. Only seven members returned to Earth in 1978. The rest had either died or chose to remain on Serpo. Those who came back were quarantined, debriefed, and lived out their remaining years in isolation.

Conclusion

Whether seen as fact, science fiction, or government cover-up, the Zeta Reticuli Exchange Program remains one of the most elaborate and captivating stories of extraterrestrial engagement ever told. The idea that Earth once engaged in a peaceful and cooperative exchange with an alien civilization opens profound questions about our place in the universe, our technological potential, and our willingness to explore the unknown.

If true, Project Serpo is more than a tale—it’s a reflection of humanity’s deepest curiosities and greatest hopes for contact beyond the stars.
