"We have just received word that the rocket ship _Space Knight_ is
within five minutes of a touchdown this spaceport. Will probably blast
off again immediately after refueling. Acknowledge, Titan!"

"I read you, Ganymede!" replied the Titan operator.

"What is your estimated time of arrival at Titan?"

The Ganymede operator was silent a moment, then announced a time that
made Strong and Walters blink in amazement. "It is based on his speed
from Earth to this point, Titan."

"Very well, Ganymede. End transmission," said the Titan man, closing his
key.

Captain Howard stared at Strong and Walters in amazement. "I can't
believe it." Strong shook his head. "It's fantastic!"

"I know it is, gentlemen," said a voice in back of them. "But
nevertheless the Ganymede station confirms it."

Strong, Walters, and Howard spun around to look into the smiling face of
Charley Brett.

Before anyone could say anything, the voice of the Deimos operator broke
the stunned silence. "Deimos to Titan, I have your information now. Are
you ready, Titan?"

"Go ahead, Deimos," said the Titan man.
