Rocketship X-M

A crew of revered scientists blast into space on mankind’s first expedition to the moon. A sudden loss of power and freak accident sends their rocket hurtling out of control, and the crew suddenly finds themselves upon Mars. They decide to take advantage of the opportunity to make a landing and explore the red planet, only to discover evidence of a demolished civilization. Convinced there are no survivors, they let their guard down just enough to learn otherwise. Rocketship X-M is considered a defining film of the 50s space-exploration genre.
