NBC新闻:天文学家庆祝阿波罗登月50周年

At the Griffith Observatory in Los Angeles. You see it? yeah. You could say the telescope's are matchmakers, linking curious humans with that bright white or 238,000 miles away. Do you ever get sick of the view up here? Never. It's so beautiful. You see the entire Los Angeles basin and of course the beautiful moon. Quick look. Dr. Laura Danly is curator here at Griffith home to the massive Zeiss telescope. You can see surfaces of other worlds and that's incredible. This week the observatory is celebrating the 50th anniversary of the moon landing. What was your feeling in that moment?

Ecstasy. I don't think there's any other way to describe it. I was crying and I was only 11. Since then we've learned a lot about the moon. One of the most important things she says is that it's really old. Before Apollo we didn't know whether it was a recent thing or an ancient thing and in fact it was formed in a huge impact right after the earth was formed. But there's still so much more to learn. Like are there resources to help us stay alive there. A dream that hasn't vanished. In 50 years my grandkids are gonna be living there. Even after all this time the moon still has a way of wowing us. Long distance relationship that endures.
