Infinity Beckoned

Infinity Beckoned traces humanity's first focused efforts to explore the inner planets with robotic spacecraft, telling the stories behind missions to the Moon, Venus, and Mars.

Jay Gallentine delves into the scientific goals, engineering challenges, and programmatic decisions that shaped these missions, with considerable attention to the Viking life-detection experiments.

The book also addresses Soviet contributions and the difficulties of researching secretive programs, combining interviews and archival work to build a thorough narrative.

Gallentine's approach emphasizes the people behind the instruments, explaining why particular experiments were chosen and how teams overcame obstacles.

The book situates these early missions within the broader trajectory of planetary science and exploration.
