"What?" cried the Solar Guard officer. "Nail it! I'm coming up!"

Scrambling up the ladder to the radar bridge from the control deck, Captain Strong rushed over to the scanner and watched eagerly as blinking flashes washed out the background of the screen.

Slowly, at times unevenly, the message flashed and the two spacemen read it with gladdening hearts. Strong made a careful note of the position while Roger continued to read the flashes. Turning to the astrogation panel, the Solar Guard captain quickly plotted a course that would bring them to Tom's position.

Endlessly, during the past few days, Strong, Roger, and Astro had swept space in a wide arc around the asteroid belt, hoping to pick up just such a signal. Now, with the position of the Avenger in his hands, Strong grabbed for the intercom.

"Attention, power deck!" yelled Strong. "We've just picked up a message from Tom. He's given us his position, so stand by for a course change."

"Yeee-eooow!" roared Astro. "I knew he'd do it."

"He's not in the clear yet. We've only got his position. We don't know how we're going to get him away from Coxine yet."

"Ready to change course, sir," said Astro.

"Three degrees on the down-plane of the ecliptic, and fifty-four degrees to starboard. Full space speed, Astro! Pile it on!"

"Aye, aye, sir!" replied Astro. "I'll make this wagon's tail so hot it'll blast at double speed!"
