Connel told him of the fight with the tyrannosaurus and Roger's injury, ending with their capture by the patrol.

"You know what's going on here, Major?" asked Astro.

"I sure do," said Connel. "And the sooner we blast them, the happier I'll be."

"One of us will have to escape and get back to the Polaris to contact Commander Walters," said Astro. "But they've got radar here as good as ours. That has to be put out of commission or they can blast any attacking fleet."

"You're right," said Connel grimly, and turned back into the room. "Tom!" he called.

"Yes, sir," replied Tom, coming up to the door.

"Since Astro and I speak Venusian—" said Connel, and then added when Tom gasped, "Yes, I speak it fluently, but I kept it a secret. That means you're the one to go. Astro and I will have more of a chance here. You escape and return to the Polaris. Contact Commander Walters. Tell him everything that's happened. We'll give you thirty-six hours to make it. At exactly noon, day after tomorrow, we'll knock out their radar."

"But how, sir?" asked Tom.

"Never mind. We'll figure out something. Just get back to the Polaris and tell the Solar Guard to attack at noon, day after tomorrow. If you don't and the fleet attacks earlier, or later, they'll be wiped out."

"What about you, sir?" asked Tom.
