1. Wolfe's attitude towards the astronaut is to show that he is an important figure for society and that it is because of this importance that people want to hear him. That's because Wolfe wants the astronaut to know that people admire what he did, seeing him as brave, intelligent and adventurous.

He sees people as "trapped" in the history of the astronaut and the figure he represents, as if there is nothing more important in the world than the astronaut and as if he were a kind of divinity.
