The cargo rockets will ferry the heavy stuff up to our space station," he explained.

"I just wanted to let you know that the first cargo rocket blasted off at 12:37."

Like the cargo rockets, the Titan had two lower stages powered by liquid fuels.

He and Bud took off in one of the empty cargo rockets.

"On the other hand, the cargo rocket has only its hull coated with Tomasite."

The next missile caught the cargo rocket squarely on the bow.

They did know, however, that automated cargo rockets were not renowned for their speed.

"Like seeing it close up from one of our cargo rockets about to arrive there," Tom thought.

"You mean we might go boom like that cargo rocket did?"

"We'll launch two probes tonight, and try shooting a cargo rocket during the next dark period."
