Space Adventures #3

Commodore Rex Clive and his Space Officers squadron investigate the mysterious disappearance of multiple space-liners near the planet Marduk, only to discover that the supposedly lightweight world is actually hollow—and harbors a sinister secret at its core. When Rex's own ship is pulled into Marduk's interior, he uncovers a vast globe suspended at the planet's center, surrounded by captured vessels and enslaved crews under the control of the ruthless Karmud. Now stranded in this impossible world, Rex and his team must find a way to break free before they too become prisoners of the mysterious sphere.

In the 1952 sci-fi tale "The Hollow World," the mysterious disappearance of ships near the colossal, low-gravity planet Marduk sends Captain Larq’s craft spiraling into its depths. When Clive and Lansing investigate, and the Space Rangers follow the Staritania into the planet’s core, they discover a hidden station where all lost vessels are moored—its trap set by the enigmatic Karmud, Master of Marduk. With Stella Dawn, Rex, and Speed trapped inside, they must find a way to outwit the planet’s unseen ruler before it’s too late.

In "The Vixens of Venus," a mysterious invasion begins when the Venusian women, led by their chief Delva, plant alien flora on Earth to sustain their planet’s giant insects. When Rex Clive and Speed are captured during their investigation, they’re taken to Venus, where Stella Dawn springs into action to rescue them. Together, the trio faces off against the Vixens in a battle for Earth’s survival.

Commodore Rex Clive and his space squadron are on convoy duty to Mars when they discover that passing cargo ships are being hijacked from a base hidden on Mercury's scorching sunward side—a mystery that grows stranger when they learn the hijackers are using an exotic metal that can withstand the planet's brutal heat. Rex must infiltrate the enemy base with the help of a double-crossing mercenary named Shangor, armed only with a daring plan involving liquid air and quick thinking to outmaneuver a superior force. It's a high-stakes game of wits across the inner planets as Rex proves that brains and nerve can trump firepower in the cold vacuum of space.

In "Convoy to Mars," Space King Rex Clive and the Space Rangers navigate the scorching gap between the Sun and Mercury, racing toward Mars through a treacherous celestial pass. There, they encounter Shangor, a grizzled old space comber, and his ragtag crew of space pirates, whose ships are shielded in Thermallium—the only metal tough enough to survive Mercury’s inferno.

In "The Time Skipper Travels to Ancient Rome," the Time Skipper, Queen Ula, and Professor Tempus find themselves in ancient Rome, where a hilariously unreliable soothsayer named Rapidus sets off a chain of events by predicting Caesar’s fate on the Ides of March. When Cleopatra, skeptical of Rapidus’s accuracy, sends word to Caesar to avoid the forum, the warning backfires—sparking Caesar’s curiosity and defiance. As Cleopatra joins the Time Skipper on a new journey through time, the past’s echoes grow ever more unpredictable.

According to some astronomers, certain moons orbiting the distant planets may be composed entirely of ice, and far from being barren wastelands, these frozen worlds could serve as crucial waypoints for future space exploration.
