"Braking rockets, aye!" acknowledged the Venusian over the intercom.
On the power deck, Astro jammed the forward drive closed and slammed open the nose rockets. The ship trembled, bucked, and finally came to a shuddering stop before it started a reverse course, accelerating quickly.
"Here it comes!" yelled Roger.
As Connel and Tom watched tensely, the space torpedo loomed large and menacing on the scanner, and then, as they held their breaths, it whistled past the silvery hull of the ship, with less than two feet to spare!
Sighing deeply, Tom brought the ship back to level flight. "We're O.K. now, sir," he said. "Her gyros are out. She won't come back."
"By the craters of Luna!" Connel suddenly exploded. "The Solar Guard spends a fortune to develop a foolproof space torpedo and two hot-shot cadets come along and get away from the blasted thing! Why haven't you told this to anyone before?"
"Why—er—" stammered Tom, "we've never had the chance to prove it, sir."
Behind them, the power-deck hatch suddenly opened and Astro stepped in. "Nice work, Tom!" he called.
"And as for you, you Venusian ape," roared Connel, "don't you realize that you can blow a reactor tube by throwing so much power into a ship without energizing the cooling pumps first?"
Astro smiled. "Not if you open the by-pass, sir," he said, "and feed directly off the pump reservoir. The gas cools the tube and at the same time expands itself and adds to the power thrust."
