Synopsis

Daryl Halbert records the albedo (reflectivity) of planets. He receives a message to return to Earth quickly. His spaceship is damaged on his way back and he is rescued by aliens. He is told that they are on their way to Earth to destroy it! Earth's albedo is falling and when it reaches zero it will break free from the Sun and become an undetectable space menace. Halbert asks for time to find a cure and is given 7 hours. He discovers that Earth has a covering of glassy space dust. A test bomb clears a small hole and proves that the Earth, and other planets in the future, can be saved.
