Commander Douglas Stansfield, age 31, an astronaut in the year 1987, is scheduled in six months to be sent on an exploratory mission to a planetary system roughly 141 light-years from Earth. Although the spacecraft will travel at the rate of 7 times the speed of light, the round trip will still take forty years. To save him the ordeal of 40 years of loneliness, he is to be placed in (newly developed) suspended animation for the twenty-year trip to his goal, and again for the twenty-year return trip. During his time in suspended animation, he will age only a few weeks.
Shortly before his mission, he meets and is enchanted by his young colleague, Sandra Horn. They meet that night, after only three and half hours, they declare their love for each other, and lament the fact that when Stansfield returns, Sandra will be an old woman.
Forty years later, Stansfield returns to Earth, a forgotten pioneer. The discoveries he made on his mission were independently achieved earlier by technology developed after his departure. Sandra is waiting for him, still 26 and lovely. She had herself put in suspended animation during Stansfield’s mission. Stansfield, however, had voluntarily disabled his suspended-animation system six months into his journey after a communications failure on his ship, and is now a man of 70. He has endured forty years of inconceivable loneliness in the hope of being with Sandra when he returned. Sandra offers to continue their relationship, but the heartbroken Stansfield urges Sandra to begin a new life without him.
After Sandra leaves, General Walters offers some small consolation to the aged astronaut: “Stansfield, you’re really quite an incredible man. It may be the one distinction of my entire life, that I knew you … that I knew a man who put such a premium on love.”
