The film was produced and released in 1950 by the
Robert L. Lippert company of Alameda, California.
It was shown extensively on television in the 1950's and 1960's.
The spaceship is called the "Rocket Ship Expedition Moon" or
"Rocket Ship X-M".
Five astronauts are launched on a rocket flight to the Moon.
An in-flight accident and possibly divine intervention send the ship to Mars.
While there, the crew finds the ruins of an atomic war and encounters
Martians living as cavemen.
The ship returns to Earth with a warning about nuclear warfare.
