Wade triggered his molecular projector, and a pale beam reached out toward the cliff. Instantly, the cliff leaped ten miles into the air, whining and roaring as it shot up through the atmosphere. Then it started to fall. Heated by its motion through the air, it struck the mountaintop as a mass of red hot rock which shattered into fragments with a terrific roar! The rocks rolled and bounced down the mountainside, their path traced by a line of steam clouds.

Then, at Arcot's order, the heat beams were all turned on the mountain at full power. In less than a minute, the peak began to melt, sending streamers of lava down the sides. The beams began to eat out a crater in the center, where the rock began to boil furiously under the terrific energy of the heat beams.

Then Arcot shut off the heat beams and turned on the molecular ray.

The molecules of the molten rock were traveling at high velocities—the heat was terrific. Arcot could see that the rock was boiling quite freely. When the molecular beam hit it, every one of those fast moving molecules shot upward together! With the roar of a meteor, it plunged toward space at five miles a second!

It had dropped to absolute zero when the beam hit it, but at that speed through the air, it didn't stay cold long! Arcot followed it up in the Ancient Mariner. It was going too slowly for him. The air had slowed it down and heated it up, so Arcot hit it with the molecular ray again, converting the heat back into velocity.

By the time they reached free space, Arcot had maneuvered the lump of rock into an orbit around the planet.

"Tharlano," he thought at the Astronomer, "your planet now has a new satellite!"

"So I perceive!" replied Tharlano. "Now that we are in space, can we use the instrument you told me of?"

Arcot established the ship in an orbit twenty thousand miles from the planet and led them back to the observatory, where Morey had already trained the telectroscope on the planet below. There wasn't much to see; the amplification showed only the rushing ground moving by so fast that the image blurred.

He turned it to Sator. It filled the screen as they increased the power, but all they could see was billowing clouds. Another poor subject.
