War of the Satellites1958

Horror Vault's take

When the United Nations pushes forward with its ambitious satellite program despite ominous warnings from a mysterious extraterrestrial force, the project becomes a battleground between human ambition and something far beyond earthly comprehension. As the mission proceeds, those involved begin to realize the threat may be closer than the stars — and far more insidious than an attack from outer space. This lean, tautly constructed Roger Corman-era sci-fi chiller channels Cold War dread into a tale of cosmic defiance and deadly consequence.
