There are mountains, plains, deserts with panoramas that take your breath away.
I truly enjoyed Greece - Santorini. That's somewhere that I always want to be.
The city of Oia is the most magnificently romantic place I've ever been.
I like Wadi Rum - it's the best view I've ever seen of what could be Mars.
In Cape Town, there's a drive from Cape Point to Camps Bay where the road is hewn out of the cliffs. It's just stunning, particularly if you do it as the sun is going down.
The beauty of Hawaii probably surpasses other places. I like the Big Island and the two mountains, Mauna Loa and Mauna Kea, where you can look out at the stars.
To experience sublime natural beauty is to confront the total inadequacy of language to describe what you see. Words cannot convey the scale of a view that is so stunning it is felt.
The advice I was given was just to make sure you look out of the window occasionally. It's something no astronaut ever gets tired of doing.
