The cover story, "Further Adventures of Mercury Man: Judgement Day," depicts a non-Earthman subjecting Mercury Man to a test that will determine whether he lives or dies, with failure resulting in ignominious defeat. In the backup feature, scientists, military leaders, and political officials select four men for a space mission in a radiation-shielded ship, with one man to be chosen within three days to fly the vessel on a final test to determine humanity's scientific knowledge of space—though the ship possesses speed that may prove insufficient, and only one of the four will survive the journey.

When the Day Comes

When the day comes that Earth encounters intelligent alien life, the story explores humanity's deep-seated fear and ego-driven resistance to the idea of being anything less than supreme. A young pilot reflects on the fate of those sent to distant satellites, wondering if their mission was doomed not by the harshness of space, but by the unpreparedness of mankind to accept a universe where they are not alone.

Paul JanusCarletonBlakelyTravers

Paul Janus, the astronaut deemed too imaginative to succeed, is unexpectedly chosen to pilot the mission through the deadly Van Allen Belts after the others fall ill.
