50's black & white movie with a white haired woman entering a flying saucer in a snow-covered landscape

Which ’50s, vintage, black & white sci-fi movie has a white-haired woman entering a flying saucer, set in a snow covered landscape? This is all I remember of the movie, but I’m pretty sure that this scene is at the end of the movie.

Being a B&W movie the woman was probably blonde. She was going back to her home planet, probably Mars considering the era. I think she/they crashed on Earth.
