There is barely a story here. The astronauts go into space and visit planet A. There they observe the planet. The narrator explains a few scientific concepts. Next they go to planet B. The same thing happens. Then they go to planet C. The same thing happens. Etc.

There is a sliver of a story between planets. It's mildly interesting, but it is really thin.

Becky Chambers does have a wonderful way with the English language, so everything flows smoothly enough, but that isn't enough to carry an entire novella.

The good news is that the gee whiz aren't we a great bunch of friends in space presentation of characters found in some of Chambers' other books isn't excessively prominent here. But... isn't that presentation why she's so popular?
