Only remember a scene. Man was on the moon or another planet. The was a sphere that opened up and sucked others in to a black nothingness.....other scene he finds a woman, possibly earlier lost colleague under the dust and dirt of the planet, he digs her out and they leave the planet in their craft.....older movie.
Yep thats not it. This one had a large round sphere sitting on the moon or a planet. It opened up and you saw blackness, it would suck you in. Can't remember if he tied himself off so that he wouldn't get pulled in, I know he finds a woman buried in the dirt near or around or even in can't remember and they take off back to earth.
