Rocketship X-M (a.k.a. Expedition Moon and originally Rocketship Expedition Moon) is a 1950 American black-and-white science fiction film from Lippert Pictures, the first outer space adventure of the post-World War II era. The film was produced and directed by Kurt Neumann and stars Lloyd Bridges, Osa Massen, John Emery, Noah Beery Jr., Hugh O'Brian, and Morris Ankrum. Rocketship X-M tells the story of a Moon expedition gone awry. Through a series of unseen events, the expedition's crew find themselve on the infamous red planet, Mars. During their time on the planet they go on to discover the remnants of a Martian civilization destroyed long ago by atomic war and now reverted to barbarism. Plot Four men and a woman blast into outer space from the White Sands Proving Ground aboard the RX-M (Rocketship Expedition-Moon) on humanity's first expedition to the Moon. Halfway there, after surviving their jettisoned and runaway first stage and a meteoroid storm, their engines suddenly quit. Recalculating fuel ratios and swapping around their multiple, different fuels finally corrects the problem. When the engines are reignited, the RX-M careens out of control on a rapid heading beyond the Moon. The increased acceleration lowers their cabin oxygen pressure, and the crew pass out. Reviving days later, they quickly discover that they have traveled some 50,000,000 miles; the RX-M is now just 50,000 miles away from Mars. Dr. Karl Eckstrom is forced to "pause and observe respectfully while something infinitely greater assumes control". The RX-M safely passes through the Martian atmosphere and lands. The next morning the crew, clad in aviation oxygen masks due to the low atmospheric pressure, begin exploring the desolate surface. They come across physical evidence of a now dead advanced Martian civilization: a partially buried-in-the-sand, stylized, Art Deco (or Tiki culture) like metal face sculpture and in the distance Moderne architecture-like ruins. Their Geiger counter registers dangerous radiation levels, keeping them well away. These dangerous levels make it clear that there was once an atomic war on Mars in the distant past. Finding cave refuge, the crew notice in the distance the primitive human descendants of that civilization emerging from behind boulders and creeping toward them. Amazed, Dr. Eckstrom comments "From Atomic Age to Stone Age". Soon after leaving, two of the explorers encounter a dark-haired woman who has lost her footing and rolled down a hill toward them; she is blind, with thick, milky cataracts
