"I can make some guesses—close enough, probably, for Discovery work." Then, after a few minutes: "Two giants, a blue-white and a bluish yellow; and a yellow dwarf."

"Dwarf in the Trojan?"

"That would be my guess, since that is the only place it could stay very long, but you can't tell much from one look. I can tell you one thing, though—unless your Zabriska is in a system straight beyond this one, it's got to be a planet of the big fellow himself; and brother, that sun is hot!"

"Now we've got to find out which one of those twelve or fifteen planets was on our line when that last message was sent.... There, we're stable enough, I hope. Open your cameras, Mase. Pull the first plate in fifteen minutes. That ought to give me enough track so I can start the job, since we're at a wide angle to their ecliptic."

"Space-ship NA774J acknowledging. No trouble...."
