Space Adventures #37

When a strange intruder with devastating weapons kills Cpl. Blackmer at Cape Canaveral, Captain Adam transforms into Captain Atom to stop the mysterious craft—only to discover it's just one of countless space prowlers converging on Earth. Racing across the Atlantic and into the ionosphere, Captain Atom finds himself outmatched by a swarm of attackers, forcing him to make a desperate choice to buy time for a counterattack. With the President's help and a view of the invaders' massive base ship, Captain Atom prepares to strike back against the alien threat.

A rocket clipper bound for Cairo vanishes into an unusual cloud bank at high altitude, triggering a desperate military response on Earth—but Captain Hargus and his crew soon find themselves aboard a massive alien vessel, where they're subjected to a chilling examination by their cosmic captors. When the ship and its passengers are sent back to Earth, the aliens must decide whether this world is worth claiming, or whether humanity's fate makes it expendable.

When Dr. Carl Egan, a mineralogy professor, encounters an alien spacecraft during a uranium prospecting expedition, its occupants declare their intention to conquer Earth—boasting that humanity has no weapons capable of harming them. As the confident invaders describe their superior world and demonstrate their formidable powers, Dr. Egan cleverly engages them in conversation about their home planet, steering the discussion toward a crucial weakness he's beginning to suspect. What unfolds is a tense battle of wits between an earthman and seemingly invincible beings from space, where knowledge of one simple terrestrial phenomenon may prove to be Earth's most powerful defense.

When an unidentified metallic satellite suddenly locks into orbit around Earth, both American and Chinese space programs race to neutralize the threat—but the crews soon discover the object is far more dangerous than expected. Captain Allison and his team must work together with their international rivals to survive the satellite's lethal mechanical defenses and confront the living creature controlling them from within. It's a tense race against time where Cold War tensions take a back seat to humanity's struggle against a truly alien enemy.

When Earth launches a television probe toward Venus, Captain Adam—a U.S. Air Force expert and special observer for the President—witnesses something extraordinary: a highly civilized Venutian woman on the broadcast. But the signal cuts out under mysterious circumstances, and Captain Adam transforms into Captain Atom to investigate what he believes is sabotage. The space traveler soon encounters the Venutian aliens themselves, who have their own reasons for wanting to meet him face-to-face.
