The somewhat misremembered traditional rules of haiku (which are totally nonstandard, in dispute and constantly ignored and broken by haiku writers of all skill levels) are: 17 syllables, arranged 5-7-5. Include a kigo (word indicating the season in which the poem takes place). No human content, only nature scenes. The first and second lines should be juxtaposed with an image in the third, probably in an interesting irony. Present tense only. Focus on single moments in natural settings. Now, please write the first line of a haiku set on an alien planet.
And now, the second line.
And the third.
