Space Adventures #43

Commodore Earl Caxton and his crew find themselves stranded in an unknown galaxy after their ship is attacked by strange vessels, only to discover they've landed on Twin I—a world ruled by King Edmond, a human descendant of Earth colonists abducted centuries ago by a superior alien race. As Caxton navigates this bewildering realm of medieval kings commanding advanced spacecraft in endless, manufactured wars orchestrated by the mysterious machine-beings who control them, he begins to uncover a dangerous truth about the chains binding these worlds.

When seven elite military pilots were chosen for Project Mercury in 1958, they underwent the most grueling preparation imaginable—from zero-gravity flights to the MASTIF spin machine, survival training in unforgiving deserts, and countless hours studying rocketry and physiology. On May 5, 1961, Commander Alan B. Shepard, alongside fellow candidates Lt. Col. John H. Glenn and Captain Virgil "Gus" Grissom, had trained harder than any humans on Earth for a single historic moment. This is the real story of the men and the intensive work that made America's first human spaceflight possible—told with the precision of eyewitness accounts and the weight of a nation watching.
