in the vacuum of space. the Doppler effect depends on the time sound takes to travel through air, and the apparent change in that sound based on how far away it is as it approaches, passes and moves away from your stationary position. (if your position is not stationary, the effect is accelerated based on your speed as well as the speed of the moving (sounding) object or mechanism. since there is no air in space through the sound would have to travel, there should be (in theory) no Doppler effect in space. if you go into space and learn otherwise - let us earthbound humans know!
Yes, we do have technology to travel to space.
