Field Trip

In the early 1600s, Johannes Kepler wrote a fantasy in which he imagined a journey to the moon:

We congregate in force and seize a man of this sort; all together lifting him from beneath, we carry him aloft. The first getting into motion is very hard on him, for he is twisted and turned just as if, shot from a cannon, we were sailing across mountains and seas. Therefore, he must be put to sleep beforehand, with narcotics and opiates, and he must be arranged, limb by limb, so that the shock will be distributed over the individual members, lest the upper part of his body be carried away from the fundament, or his head be torn from his shoulders. Then comes a new difficulty: terrific cold and difficulty in breathing. The former we counter with our innate power, the latter by means of moistened sponges applied to the nostrils.

Somnium is largely a treatise on lunar astronomy, describing the motions of the planets as observed from the moon. But Kepler also considers the appearance of the moon’s inhabitants, who “wander in hordes over the whole globe in the space of one of their days, some on foot, whereby they far outstrip our camels, some by means of wings, some in boats pursue the fleeing waters, or if a pause of a good many days is necessary, then they creep into caves.” Carl Sagan and Isaac Asimov called it the first work of science fiction.
