"I've gone this far, and I'm not quitting now."

They turned to face Roger.

"Well, how about it, Roger?" asked Tom. "No one will think you're yellow if you take the jet boat and leave now."

"Ah—talk again!" grumbled Roger. "We always have to talk. Let's be original for a change and just do our jobs!"

"All right," said Tom. "Take an emergency light and signal Captain Strong. Tell him what we're going to do. Warn him to stay away—about two hundred miles off. He'll know if we're successful or not within a half hour!"

"Yeah," said Roger, "then we'll send him one big flash to mean we failed! Bon voyage!"

Fifteen minutes later, as the Lady Venus drifted in her silent but deadly orbit, Tom, Roger and Astro still worked feverishly as the Geiger counter ticked off the increasing radioactivity of the wildcatting reaction mass in number-three rocket tube.

"Reading on the counter still's going up, Astro," warned Roger. "Fifteen-O-five."

"Hurry it up, Astro," urged Tom.

"Hand me that wrench, Tom," ordered Astro. The big cadet, stripped to the waist, his thick arms and chest splattered with grease and sweat, fitted the wrench to the nut and applied pressure. Tom and Roger watched the muscles ripple along his back, as the big Venusian pitted all of his great strength against the metal.
