Homer Hickam is a kid with only one future in sight, to work in the local coal mine like his father. However, in October 1957 everything changes when the first artificial satellite, Sputnik, goes into orbit. When Homer sees the Soviet satellite streak overhead, he becomes inspired to learn how to build rockets. With the help of his friends, and the local nerd, Homer sets to do just that by trial and a lot of error. Unfortunately, most of the town, and especially Homer's father, thinks that they are wasting their time. Only one teacher understands their efforts and lets them know that they could become contenders in the national science fair with college scholarships being the prize. Now the gang must learn to perfect their craft and overcome the many problems facing them as they shoot for the stars.

From 1957 —the year in which the Soviets put the Sputnik 1 satellite into orbit— to 1969 —when American astronaut Neil Armstrong walked on the surface of the moon—, the beginnings of the space conquest were depicted in popular culture: cinema, television, comics and literature of the time contain numerous references to an imagined future.

The news that the Soviet Union had succeeded in launching an artificial moon for the first time in history on October 4, 1957 hit like a bombshell. Sputnik1 is the talk of the town. A metal ball weighing 83 kg with a diameter of 58 cm, hurtling around the globe at cosmic speed.
