In Poul Anderson's "Lodestar," Coya Conyon, travelling in an Ythrian spaceship:
breathes air thinner than Terrestrial;
smells the slight smokiness of Ythrian bodies;
hears through the ventilator the wingbeats of crew members cavorting in a large hold;
is exhilirated by 0.75 Terrestrial gravity.
We check the earlier story about first contact with Ythri for consistency. See here. We also check for information about Ythri on a companion blog. See here. And, finally, we say good night.
(The Grand Survey is a five-year mission, as in Star Trek.)
