Have Space Suit—Will Travel

The novel is set in the near future, when the Earth has established some lunar bases. High school senior Clifford "Kip" Russell is determined to get to the Moon, but the price of a ticket is far beyond his reach. His father suggest he enter an advertising jingle-writing contest; first prize is an all-expenses-paid trip there. Instead, he wins a used space suit. Kip puts the suit (which he names "Oscar") back into working condition.

Kip reluctantly decides to return his space suit for a cash prize to help pay for college, but puts it on for one last walk. As he idly broadcasts on his shortwave radio, someone identifying herself as "Peewee" answers and requests a homing signal. He is shocked when a flying saucer lands practically on top of him. An 11-year-old girl (Peewee) and an alien being (the "Mother Thing") flee from it, but all three are quickly captured and taken to the Moon.

Their kidnapper ("Wormface") is a horrible-looking creature who contemptuously refers to all others as "animals". Wormface has two human flunkies ("Fats" and "Skinny") who assisted him in initially capturing the Mother Thing and Peewee, a preteen genius and the daughter of an eminent scientist. The Mother Thing speaks in what sounds like birdsong (illustrated by a few musical notations), but Kip and Peewee have no trouble understanding her.

Kip, Peewee and the Mother Thing escape and try to reach the nearest human base on foot, but they are recaptured and taken to a base on Pluto. Kip is thrown into a cell, later to be joined by Fats and Skinny, who have apparently outlived their usefulness. After Skinny is taken away, Fats tells Kip that his former employers eat humans, before he himself disappears.

The Mother Thing, meanwhile, makes herself useful to their captors by constructing advanced devices for them. She manages to steal enough parts to assemble a bomb and a transmitter. The bomb takes care of all but one of the Wormfaces, and between them, Kip and Peewee deal with the last one. The Mother Thing freezes solid when she tries to set up the transmitter outside without a spacesuit. Kip puts Oscar on and activates the beacon, but becomes severely frostbitten in the extreme cold. Help arrives quickly. Kip, Peewee and the Mother Thing are transported to Vega 5, the Mother Thing's home planet.

Kip is kept in a state of cryopreservation while the Mother Thing's people figure out how to heal him. It turns out that the Mother Thing is far hardier than Kip had suspected and freezing did not hurt her. While Kip recuperates, a Vegan anthropologist Kip nicknames "Joe" learns about Earth from Peewee and Kip. Once Kip is well, he, Peewee, and the Mother Thing travel to a planet in the Lesser Magellanic Cloud, to face an intergalactic tribunal, composed of many advanced species which have banded together for self-protection.

The Wormfaces are put on trial first. Their representatives are so arrogantly xenophobic that they promise to destroy the "animals" who dared to try the "Only People", and are judged to be dangerous. Their planet is to be "rotated" 90° out of the present space-time ... without their star - most likely dooming them to freeze to death.

Then it is humanity's turn, as represented by Peewee, Kip, Iunio (an ancient Roman centurion), and a Neanderthal man. The Neanderthal is rejected as being of another species. Iunio proves belligerent, but brave. Peewee's and Kip's recorded remarks are then admitted into evidence. In humanity's defense, Kip makes an impassioned speech. The Mother Thing and a representative of another race argue that the short-lived species are essentially children who should be granted more time to learn and grow. It is decided to re-evaluate humanity after "a dozen half-deaths of radium" (19200 years).

Kip and Peewee are returned to Earth with advanced alien devices and scientific equations provided by the Vegans to help the human race. Kip passes the information along to Professor Reisfeld, Peewee's father. Reisfeld arranges a full scholarship for Kip at the Massachusetts Institute of Technology, where Kip wants to study engineering and spacesuit design.

Since the advent of amateur radio satellites in 1961, the majority have been known as Orbital Satellite Carrying Amateur Radio – OSCAR.[2]

An amateur radio satellite, dubbed SuitSat, was launched from the International Space Station in February 2006. This was an obsolete space suit with a ham radio transmitter inside it.

Floyd C. Gale wrote that the book "is possibly the most unabashedly juvenile of Heinlein's long list ... Great for kids, chancy for grownups who don't identify readily with adolescent heroes".[3]

In 2010, it was announced that Star Trek writer Harry Kloor had written a script for a film version and optioned the film rights. The film was expected to have come out in 2013,[4][5] but as of the end of 2013 was still listed as "in development".
