The Fifth Part of the Year Three

Within its broad array of nested rings, the planet was a seething storm. It had always been so. Patterns chased themselves across its brown-on-brown face in bands and curlicues. The space around it churned with activity: billions of icy particles in a broad array of nested rings; Bights of moons; streamers of dust whipped by powerful magnetic fields; all whirling around at terrific velocities, at several makasrupkithp per breath. Message Bearer maneuvered within that storm.
The Herdmaster's Advisor, gazing raptly through the thick double window, seemed to notice only the beauty of the scene.
The Herdmaster found that irritating. His own domain included collisions, industrial operations, internal quarrels, and the peaceful integration of sleepers with spaceborn. He had quite enough problems without ... that.
Message Bearer's main telescope was the equal of any astronomical installation on the world they had left behind. The alien probe was close now, by astronomical standards, and the screen showed it in fine detail.
A circular antenna. A pod at the tip of a long boom radiated infrared warmth. That would be the power supply. Two more booms thrust instruments outward. Clasp digits with me, that I may know your herd! One extension held what had to be cameras, the other some kind of electronic sensing device.
