In pretty much every type of fictional media, they ignore what a colossally bad idea it would be to actually visit a planet with any kind of life without years or decades of research ahead of time. The microbes or other life there could eat us for lunch, or we could carry ones there that would decimate their life. It would be the whole Indians/smallpox thing but potentially much worse. So if we ever go for real, we’d want to be sure that was handled. But as most people are saying, leave it to the robots.
