Rocketship X-M
1950 film by Kurt Neumann

Rocketship X-M (also known as 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 unforeseen events, the expedition's crew find themselves on Mars. They 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 corrects the problem, supposedly allowing continuing to the Moon. When the engines are reignited, the RX-M careens out of control on a rapid heading beyond the Moon. The increased acceleration causes the crew to lose consciousness.

Why this record matters
“Rocketship X-M” is worth following because a concise public description often conceals a longer documentary argument. Here, Rocketship, film and Kurt provides the most credible route into that argument.
Attribution, date and provenance are strongest when supported by the original work, a catalogue record and documented transmission. The source revision retrieved here is dated Aug 10, 2026. The linked authority identifier is Q1757751. 2 of 2 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1950.
Rights, attribution and provenance may remain disputed even when a general reference summary presents a stable account. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
