In this incredible video we can see Chang'e-4 in it's final approach and landing on the moon from the point of view of the spacecraft.
The view is horizontal as the spacecraft seems to stop and hover over the chosen site, and then the view pitches forward until it is looking straight down. Then the spacecraft descends and lands. Specifically
01:10 in the video.
The speeds are slow and the altitudes are low so I assume that the engine should be pointed mostly down the whole time, but that conflicts with the view.
Can someone explain to me how the spacecraft hovers so nicely and yet appears to pitch forward by 90 degrees so gracefully?
