Bradbury wrote mainly about Americans going into space, and they were mainly Americans from small mid-western towns. Mars might transform them - it is the colonists on Mars who become dark and golden-eyed, but they still want to take their stoops with them, so they can spend the evening sitting. And when you're in space without a Christmas tree, the stars make a good candle substitute. Bradbury shows us another side to this, though, in stories I didn't really know, set among the hispanics in the barrios of the border states and central America. Most of these are realistic, like "The Little Mice" and "The Wonderful Ice-Cream Suit", about the life of hispanic underdogs, but "And The Rock Cried Out" is apocalyptic. "Rock" describes a WASP couple trying to get back to civilisation while they've been in the Mayan jungle at the time nuclear war has wiped out the first world. Now the indians and the latins can show the loathing for the exploitation they have experienced from long before the Monroe Doctrine, and the couple have nowhere to go. They do not have the author's assurance of what that world will be like.
So when you inhabit Bradbury's world you have confidence in space and the distant planets, but here and now is empty and dubious, full of the same sort of spirit that he described in Death Is A Lonely Business.
This collection includes all these things and I found the mixture quite appetizing.
