Moon landing, a high-tech term that seems particularly impressive to ordinary people, just another everyday term like 'going out to buy soy sauce' to the Xyrin Apostle, and equivalent to 'the TV show is starting!' to Qianqian. In short, it's a suddenly highly relevant term to many people.

Surprised at how rapidly this world is progressing and at how many countries have secretly prepared probes and spacecraft ready to launch at any moment.
