"Venus and the Ark" a spoof?

This dystopian poem has been called a spoof, but it is not a spoof in the same way that the "Scary Movies" are a spoof.  Current movie spoofs take a movie idea and add some humor, but usually take away from the meaning of the movie, while this poem "Venus and the Ark" may still be a spoof because it has obvious allusions to Noah and the Ark, the animals, and the name of the story.  The poem also has some characteristics of a spoof because of how such a tiny thing such as flying to Venus causes the end of the human race, which is possible, but probably a bit of an exaggeration.  However, Anne Sexton still presents a rather serious topic of how even when man is gone, the universe will still keep turning.
