What is Chekov saying in the Star Trek 2009 reboot?

The scene where Kirk and Sulu are in free fall together after trying to destroy Nero’s drill at Vulcan. Chekov is trying to transport them back onto the Enterprise before they splat into the ground. When Chekov succeeds, he says something in Russian. It sounds like “your-my-your!” Anybody know what that means in English?

I’m guessing боже мой (bozhe moi) = my god.

Here’s the scene, cued up to just before the transport. Sounds to me like “yah moy you,” phonetically, but I’m not sure exactly what the Russian is. @mikecurtis, I was thinking maybe “bozhe moi,” too, but it doesn’t sound like that to me in this clip, and context suggests it’s more of an expression of relief or happiness.

IMDB, in the trivia entries for the movie, says this:

Fascinating.
It seems to be a bowlderized curse.
