It's a sci-fi movie. I think from the 80s, but then again could be like from the 70s. Now I don't remember much about it... just some scenes and I don't know if it was a real horror movie or not since it scared the heck out of me when I was a kid. The first scene I remember was a dead long haired dude floating in space near a shuttle or a spacecraft and a guy in a spacesuit saw it and was spooked out.
The other most embedded in my mind is this one... a guy is in a tent... and what appears to be the moon... or maybe another moon or a planet... anyway it looks like the moon... so he is inside the tent and the tents door has a tiny window where he sees his buddies head, but that's not his buddie, but a space monster or something who has ripped his buddies head off or something...

So that's about it... the long haired dead dude floating aroun (who I think was alive at one point of the movie, but still looking kind of dead) and the tent scene on the moon with the creepy creature.

So ring any bells?. anyone?

It's the 1989 flick Moontrap (http://www.angelfire.com/film/not-good/Reviews/Moontrap/Moontrap.htm) with Walter Koenig and Bruce Campbell. Koenig! Campbell! Together at last!

Well thanks a bunch... I do believe this is the one Ive been looking for... many thanks!! =)
