Mission of Gravity is a science fiction novel by Hal Clement. The title is a play on words, involving two uses of the word "Gravity," one meaning "Gravity, the force which pulls" and the other being "Gravity, extremely serious or important". The novel was serialized in Astounding Science Fiction magazine in April–July 1953. Its first hardcover book publication was in 1954, and it was first published as a paperback book in 1958. Along with the novel itself, the book also includes "Whirligig World", an essay by Clement on creating the planet Mesklin that was published in the June 1953 Astounding.

Clement published two sequels to Mission of Gravity, a 1970 novel called Star Light, and a 1973 short story called "Lecture Demonstration". Mission of Gravity was nominated for a "Retro Hugo" Award for the year 1954.

[edit] Setting

The story is set on a highly oblate planet named Mesklin, which has surface gravity that varies between 700 g at the poles and 3 g at the equator. The story is told from the points of view of one of the local intelligent life forms and a human explorer. The locals are centipede-like, in order to withstand the enormous gravity, and terrified of even small heights (because in 700 g even a tiny fall is fatal). (See Mesklin for a more comprehensive description of the planet's characteristics.)

[edit] Plot summary

The native protagonist, Barlennan, a captain of a Mesklinite trading vessel, is on an expedition to the equator, where the gravity is a tiny fraction of what his culture is used to. At the story's opening, he has made contact with human explorers, who are barely able to survive the incredibly light (to the captain) gravity of the equator. The humans request that he recover readings from a scientific probe the humans had sent to one of the poles of the planet. The captain agrees, and the remainder of the story deals with the journey from the equator to the pole, and the recovery of the probe. Along the way, the ship encounters and overcomes a variety of obstacles, some of which the humans (who have provided the captain with radios in order to keep in contact) can help with, and some of which they cannot.

[edit] Themes

A significant theme of the novel is the universality of physical law; regardless of the exotic nature of the location, the underlying rules of the universe are constant. Even in an environment of hundreds of gravities, the story states, a boat will still float (assuming structural integrity), because even if the weight of the boat is considerably greater than it might be, for instance, at Mesklin's equator, the weight of the fluid it displaces is also greater. A secondary theme deals with the scientific method, and the necessity of proceeding one step at a time. The trading ship's captain, originally skeptical of the human explorers' claim that teaching him to make the various devices they use would take prohibitively long, gradually grows to accept this explanation, and sees the value of walking before he can run, as it were—a theme not at all surprising in a work by Hal Clement, a high school science teacher.

[edit] Reputation

It is most often praised for the thoroughness and care with which Clement designed and described Mesklin—even today, it is considered one of the definitive examples of worldbuilding. Although Clement has stated that his original calculations concerning the polar gravity of Mesklin were inaccurate (he later estimated the polar gravity should have been ~250 g instead of 700), the exploration of what existence might be like in such extreme conditions is detailed, convincing, and persuasive. Clement's characterization, unfortunately, is less impressive, and one rarely gets the impression that his viewpoint character and associates are, in point of fact, foot-long alien centipedes living in a hydrogen atmosphere.[original research?]

The novel is frequently invoked in discussions of the sense of wonder, the sensation of dawning comprehension and understanding of a larger context for a given experience, that many readers of science fiction point to as the reason why they pursue the genre. Its occasionally superficial writing and shallow characterization should not, in any way, be considered as lessening the novel's importance to the field, or its position as one of the classics of the genre.
