Since The Green Hills of Earth and The Menace from Earth were originally two separate short story collections, I am going to rate them individually.
The Green Hills of Earth
Complete Collection Rating: 7/10 (Good)
This short story collection gathers together many stories from the middle portion of Heinline's Future Histories series. These stories really run the gamut quality wise. Two stories in particular soured the bunch for me, Delilah and the Space Rigger and The Black Pits of Luna.The other stories in the collection are significantly better.
Story Ratings:
Delilah and the Space Rigger - 3/10 (Really Bad)
A female engineer is hired to work on a space station and all sorts of ridiculousness ensues. I realize that this story was written in 1949 and I appreciate that Heinline was going up against sexism in an era that thought of woman mainly as housewives and mothers. So while this issue is one that I applaud Heinline for tackling, I felt his execution was very poor. The story was boring and uninteresting. The characters were paper thin and the dialogue was corny. It's an instantly forgettable story.
Space Jockey - 7/10 (Good)
This story is about an eventful flight to the Moon. While I enjoyed this story as a whole, the scene that sets off the major conflict bothered me somewhat. In this scene a young boy and his father are being shown the cockpit of a spaceship while in flight from the Earth to the Moon. The kid hits some buttons in the cockpit and throws the ship off course and creates numerous problems. First off, it is highly unlikely that anyone other than crew would be allowed in the cockpit during flight. I know that on airplanes, cockpit tours are sometimes given to children pre-flight, but obviously never during flight. Secondly, the fact that this kid wasn't reprimanded in any way for his actions seems a bit unbelievable to me. Other than my gripes with this scene, the rest of the story is pretty good.
The Long Watch - 9/10 (Awesome)
This is an awesome story about a coup on the Moon. It's one of the best that I've read from Heinline. Heinline seems to be at his best when he writes stories that place his main characters in mortal danger. Even though this story is short, a good deal of character development happens with the protagonist. He feels believable, his actions make sense and his thoughts and dialogue seem appropriate for the situation he's in. The stories conclusion is fitting and I felt satisfied and even a bit choked up emotionally as I finished reading.
Gentlemen, Be Seated - 7/10 (Good)
A tale about an underground construction project on the moon. Another good story, though not exceptional. I just didn't feel like there was quite enough character development in this one for me to truly care about the plight of the characters. Of the Heinline stories that I've read, this one ranks somewhere in the middle as far as character development goes. It's not the best, but it is far, far from the worse. As I said, the story itself is quite good with some nice tension to boot. The only thing missing is a bit more depth from the characters.
The Black Pits of Luna - 3/10 (Really Bad)
The core of this story is about a bratty kid that throws temper tantrums to always get his own way. His behavior is terrible and he simply does whatever he wants. Thus, he manages to get himself lost on the surface of the moon. His parents are completely incompetent idiots and their kid is a product of their ineptitude. I hate stupid characters that lack even a shred of common sense and this story is chocked full of that type of character. Thankfully the oldest of the two children actually has a brain in his head. He manages to save his little brother; unfortunately he can't save this awful story as well.
"It's Great to Be Back" - 7/10 (Good)
This is a neat little "grass is always greener" story about a couple longing to move back to Earth after living on the Moon for 3 years. Once they get to Earth however, they begin to realize how much they miss the life and culture they left behind. It's a well written, charming little story.
"-We Also Walk Dogs" - 7/10 (Good)
This story is about a company that specializes in providing its' customers with every conceivable legal service. When the government contracts them to coordinate a inter-planetary, inter-species assembly to be held on earth, they are off the races to find a scientist who can create a device for aliens from low-gravity worlds which will enable these aliens to attend the assembly. A good story that unfortunately mires itself in techno-babble and almost completely refrains from character development.
Ordeal in Space - 5/10 (Mediocre)
While I liked the sections of the story that detail the protagonist's misadventure in space and his subsequent difficulty dealing with a severe case of vertigo and fear of heights, the story falters mightily about two thirds of the way through. Once the main character decides to step out a window onto a 6 inch ledge 35 stories off the ground to rescue a cat, this story goes from science fiction to Saturday morning cartoon in the blink of an eye.
The Green Hills of Earth - 7/10 (Good)
A very short story about a space exploring singer/songwriter who loses his sight in an accident. It's short and to the point, yet interesting and engaging with a tight and perfectly fitting conclusion.
Logic of Empire - 8/10 (Really Good)
A story about slavery on Venus. The whole process of becoming an indentured servant is well thought out and sharply detailed. The story builds up a continuous sense of dread as the protagonist slowly comes to grips with the magnitude of the situation he is in. The palpable and well crafted atmosphere gives the already solid storytelling an additional boost of quality.
The Menace from Earth
Complete Collection Rating: 7/10 (Good)
Only the short story The Menace from Earth from this collection is part of Heinline's Future Histories Timeline. The rest of the stories range from time travel yarns to disaster stories. It's a solid collection that nicely shows off Heinline's versatility.
The Year of the Jackpot - 7/10 (Good)
A statistician who tracks world events and strange occurrences figures out that the planet is headed for disaster. The two main characters are fairly well developed and the story moves along at a nice clip. Heinline does an excellent job of transitioning from a faux science fact story at the beginning to a post-apocalyptic one in the end. The transition is seamless and natural and lends a sense of believability to the story.
By His Bootstraps - 7/10 (Good)
Aside from the fact that the main character is a bit dense and slow to catch onto things completely obvious to the reader, I still feel like this is a pretty solid time travel yarn. However, it is not on the same level as All You Zombies another time travel short story written by Robert Heinline. When comparing the two, By His Bootstraps is a much more straightforward tale that lacks the mind bending twists and turns of All You Zombies.
Columbus was a Dope - 6/10 (OK)
This very short story is a debate about exploration and the adventurer's spirit. One party is in favor of building a generation ship and the other is against human progression and exploration. However, the story is fraught with irony since the debate takes place in a bar on the Moon.
The Menace from Earth - 9/10 (Awesome)
This is a love story of sorts. It's also one of my favorite stories by Robert Heinline. The characters and dialogue are solid, but the real standout here is the setting and the execution of the narrative. The level of detail put into the flying sequences is fantastic. I was captivated by the whole idea of being able to fly using specialized wings and the benefit of lower gravity on the Moon. The Bats' Cave, a two mile wide and 1,000+ foot high underground volcanic bubble is used as a giant recreational flying facility. For anyone who ever dreamed of flying as a kid, this story will reignite your imagination.
Sky Lift - 7/10 (Good)
An alien disease is ravaging a research facility on Pluto and the Earth Military is tasked with sending emergency aid. However, if aid is to arrive on time, the ship must fly at near lethal acceleration. Heinline does a nice job here describing the toll placed on the pilot's bodies at 3.5 G's. It's a well written, yet straightforward tale involving the trope "the sacrifice of a few for the good of many".
Goldfish Bowl - 6/10 (OK)
The appearance of twin pillars of water that stretch from the ocean to the clouds, sparks a research mission that quickly goes south. While I liked the stories' concept, setting and build up, the second half slows down to a snail's pace. The majority of the second half is spent theorizing the possible origin of the entity that created the pillars. Aside from the loads of speculation and conjecture, we never really learn anything regarding the mysterious entity. So in the end we are left with a cryptic warning message about evolution and very little plot resolution.
Project Nightmare - 7/10 (Good)
This story is about an imminent Russian attack on US soil. Russian A-Bombs are hidden in 38 US cities and unless America converts to Communism, Russia will detonate the bombs. In a desperate attempt to find and diffuse the bombs, the US Government enlists the help of a group of people with ESP (Extra-Sensory Perception), telepathy, telekinesis and the like. This story has a good mix of character development, exposition, action and tension. In addition, the pacing is tight and the narrative well-balanced.
Water is for Washing - 7/10 (Good)
When an earthquake drops part of the California coast below sea level, a group of people attempt to outrun the tidal wave and ensuing flood. Another solid story that nicely caps off the collection. Of all the Heinline stories I've read, this one might be the least science fiction among them. This natural disaster story feels like a very realistic possibility.
