Battle in Outer Space (1959) Timeline Explained – Every Event in Order

The disasters are caused by an alien force from the planet Natal. Their technology manipulates gravity by lowering temperatures, which reduces Earth's gravitational pull on objects, making them easier to lift. This is how bridges float, trains derail, and ocean liners are lifted from the sea. The pattern reveals an intelligent, hostile presence testing Earth's defenses.

Dr. Ahmed is initially shown experiencing a crippling headache during the UN conference. He briefly leaves the meeting and in the courtyard, Etsuko Shiraishi witnesses him being enveloped by a red light from the sky. This alien contact implants a tiny radio transmitter within him, allowing Natal to mentally influence his actions and gather intelligence on Earth's defense plans.

Foreshadowing: Ahmed's headache at the meeting hints that something is already affecting him before the visible alien contact.

After Dr. Ahmed is vaporized by a Natal saucer for failing to complete his sabotage mission, forensic examination reveals a tiny radio transmitter lodged within his body. This device transmits signals to a celestial origin, locus Natal, on the Moon, giving Earth investigators the critical clue they need to launch a reconnaissance mission.

During the journey to the Moon, Iwamura comes under alien mind control from Natal. The Natal influence compels him to attempt disabling the spacecraft's weapons, endangering the entire crew. This mind control is later broken once the team reaches the Moon and destroys the Natal base, freeing Iwamura to rejoin the mission.

Foreshadowing: The earlier mental influence over Dr. Ahmed establishes that Natal possesses mind-control technology.

Following the successful Moon mission that destroys the Natal base, Earth develops two key weapons: Rocket Fighter Planes based on the X-15 and the Atomic Heat Cannons. In the final battle, Earth's space fighters engage the surviving Natal saucers while the Atomic Heat Cannons deliver a decisive strike that pierces and destroys the Natal mothership, ending the invasion.

After breaking free from Natal's mind control, Iwamura chooses to remain behind on the Moon to provide covering fire for SPIP-2's retreat. He detonates SPIP-1, sacrificing his own craft and life to ensure his comrades can escape safely. This act enables the surviving team to return to Earth with the intelligence needed to prepare humanity's counterattack.

• covering fire
• heroism

The SPIP rockets are attacked by remotely controlled meteors called space torpedoes. These are alien weapons designed to disrupt the spacecraft's trajectory and destroy the mission before it reaches the Moon. The SPIPs manage to evade these attacks and continue to the Moon despite sustaining damage and the added threat of Iwamura's mind-controlled sabotage attempt.

The Natal beings appear to be testing Earth's defenses and readiness before launching a full-scale invasion. Their initial gravity-manipulation disasters serve as both a probe of human capabilities and a demonstration of their technological superiority. When Dr. Ahmed is controlled, he states that Natal intends to colonize Earth, revealing their ultimate motive: conquest and occupation of the planet.

During the assault on the Natal base in the lunar crater, Etsuko Shiraishi is briefly captured by alien forces. Major Katsumiya rescues her in the heat of a close-quarters engagement with energy beams. This incident occurs as the ground teams coordinate their attack to destroy the Natal operations on the Moon.

Foreshadowing: Etsuko's earlier observation of Ahmed's alien contact establishes her as someone present at key moments.

The Natal mothership deploys anti-gravity rays capable of lifting massive objects, including entire cities. After striking New York and San Francisco with space torpedoes, the mothership descends on Tokyo and unleashes an ocean of anti-gravity energy that devastates the metropolis. This weapon represents the primary threat that Earth's defenses must counter to prevent total annihilation.
