Similarities to Interstellar

[Andrew]

I watched "Interstellar" last night and couldn't help but think of this book while watching it. It seemed to have very similar themes, such as the loneliness of long range space travel, and also involved the slowed aging resulting in watching loved ones grow old more quickly. Any thoughts?

To be honest it is difficult to get any science fiction work that doesn't owe some debt to Heinlein. As Spider Robinson said in an article
"I don't believe there can be more than a handful of science fiction stories published in the last forty years that do not show his influence one way or another. He has written the definitive time-travel stories (“All You Zombies—” and “By His Bootstraps”), the definitive longevity books (Methuselah's Children and Time Enough For Love), the definitive theocracy novel (Revolt in 2100), heroic fantasy/SF novel (Glory Road), revolution novel (The Moon Is a Harsh Mistress), transplant novel (I Will Fear No Evil), alien invasion novel (The Puppet Masters), technocracy story (“The Roads Must Roll”), arms race story (“Solution Unsatisfactory”), technodisaster story (“Blowups Happen”), and about a dozen of the finest science fiction juveniles ever published".
