Awakening in a Strange Place

Ryland Grace awakens in a high-tech spaceship, disoriented and with no memory of his identity or purpose. As he explores, he discovers he is alone on a mission to save Earth from a solar catastrophe caused by a microorganism called Astrophage. The ship, Hail Mary, is his only companion, equipped with advanced technology and powered by Astrophage. Grace struggles to piece together his fragmented memories and understand his critical role in this mission.

Discovering the Mission's Purpose

Grace recalls Earth's dire situation: the sun is dimming due to Astrophage, threatening humanity's survival. The Hail Mary mission is a desperate attempt to find a solution by traveling to Tau Ceti, a star unaffected by Astrophage. Grace realizes he is on a one-way mission to discover why Tau Ceti is immune, hoping to save Earth. As he learns about the ship's capabilities, he understands the gravity of his task and the importance of his scientific expertise.

First Contact with Aliens

While investigating the Tau Ceti system, Grace encounters an alien spacecraft powered by Astrophage. The ship attempts to communicate through light signals, and Grace responds, establishing a rudimentary form of communication. This encounter confirms the existence of intelligent life beyond Earth, and Grace realizes the aliens might be facing the same Astrophage threat. The possibility of collaboration emerges, but the risks of interaction are significant.

The Alien Message

The aliens send a cylinder to Grace's ship, revealing their origin from the 40 Eridani system, which also has a Petrova line. This suggests they are dealing with the same Astrophage problem. Grace deduces that the aliens share his goal of understanding Tau Ceti's immunity. This shared objective could lead to collaboration, but Grace must weigh the risks of trusting the aliens against the potential benefits of their knowledge.

Preparing for the Unknown

Grace contemplates the risks and benefits of meeting the aliens, who propose a tunnel to connect the two ships. Despite potential dangers, Grace decides the opportunity to learn from them is too valuable to pass up. He prepares for the meeting, knowing it could be the key to saving Earth. This decision marks a pivotal moment in his mission, as he balances hope for collaboration against fear of the unknown.

Unexpected Engineering Revelation

Grace and Rocky, an Eridian engineer, collaborate to solve the Astrophage crisis. Rocky reveals his journey to Tau Ceti took only three years, despite calculations suggesting it should have taken longer. Grace realizes Eridians are unaware of relativistic physics, explaining the discrepancy. This revelation provides Grace with surplus Astrophage fuel, offering a chance to return to Earth and reigniting hope for his survival.

The Chain of Salvation

Grace and Rocky construct a 10-kilometer chain from xenonite to collect samples from Adrian's atmosphere. The process is grueling but crucial for finding a solution to the Astrophage problem. The chain represents a lifeline, a physical connection to the possibility of saving both Earth and Erid from extinction, highlighting the importance of innovation and teamwork.

A Dangerous Descent

With the chain complete, Grace and Rocky execute a daring plan to lower a sampler into Adrian's atmosphere. The Hail Mary must maintain a delicate balance to avoid vaporizing the chain. The maneuver is fraught with danger, but Grace successfully retrieves the sampler, though the ship's structural integrity is compromised. This triumph adds urgency to their mission, underscoring the risks they must take to succeed.

The Astrophage Predator

Analyzing samples from Adrian, Grace discovers a potential predator of Astrophage. This groundbreaking discovery suggests a natural balance in Adrian's ecosystem that could control Astrophage populations. The presence of a predator offers hope for a solution to the crisis, emphasizing the importance of their mission and the potential for collaboration between species.

A New Hope for Earth

In a moment of camaraderie, Rocky reveals he has enough surplus Astrophage fuel to allow Grace to return to Earth. This unexpected generosity transforms Grace's mission from a one-way trip into a potential round trip, reigniting his hope for survival. Rocky's offer strengthens their bond and highlights the power of cooperation in the face of a shared existential threat.

Desperate Search for Rocky

Grace, aboard the Hail Mary, searches for Rocky's ship, the Blip-A, which has gone silent. Using the ship's spin drives and Petrovascope, Grace conducts a meticulous search across space. After a tense process, he detects a faint signal, confirming the Blip-A's location. Despite the odds, Grace is determined to reach Rocky, knowing his friend's life and Erid's fate depend on it.

Taumoeba's Unintended Consequences

Grace discovers that Taumoeba, a microorganism he engineered, has evolved to penetrate xenonite, consuming all Astrophage fuel aboard the Blip-A. This unintended consequence leaves Rocky stranded, and Grace realizes the gravity of his mistake. The potential catastrophe for Rocky and his people forces Grace to confront the ethical implications of his scientific endeavors.

A Hero's Dilemma

With Rocky's ship derelict, Grace must choose between returning to Earth to save humanity or rescuing Rocky to save Erid, knowing it will cost him his life. The weight of both worlds rests on his shoulders, and he grapples with the moral implications. Ultimately, Grace decides to save Rocky, sending Taumoeba to Earth and setting course for Erid, accepting his fate.

A New Hope for Erid

Grace reaches the Blip-A and reunites with Rocky, who is alive but in dire straits. Together, they plan to use the remaining Astrophage aboard the Hail Mary to return to Erid. Rocky is overjoyed, and the two friends work tirelessly to ensure the survival of both species. Grace's selfless act offers new hope for Erid, as they prepare for the journey home.

Final Farewell and New Beginnings

Years later, Grace reflects on his life on Erid, where he is revered. The Taumoeba successfully saved Earth, and he finds solace in his sacrifice. Though he will never return to Earth, Grace has found a new home among the Eridians, teaching and sharing knowledge. His enduring friendship with Rocky highlights the possibilities of future interstellar connections.
