Europa loomed below us, now, and Jupiter dead ahead. The oxygenator sent its draft along the back of my neck, and I shifted in my seat, remembering his question about artificial insemination. That in itself could be considered subversive. Not that I hadn't thought it, and millions of others, but he'd _voiced_ it. The scientists had the money, the power, the commerce. And hadn't they earned it? Hadn't they made all this quite possible? We hadn't said a word right up to the time I put the forward blasters on for the Jupiter mooring. The buzzer from the rear hatch was buzzing now, and I threw the switch to open it. Van Elling came in with his duryllium helmet on, beating his hands on his thighs. Collins helped him with the helmet, and Van said, "Cold, cold, cold, cold, cold. Chief, we might lose a couple minutes on the loading. Those boys aren't what they were when we bought them." Through the oxygenator, I could smell ammonia and burning elgeron. I went to the viewer room and switched to the landing ramp. The robots were moving down the ramp at a pace which might have been slower than usual, but didn't seem so to me. Behind me, I could hear Van Elling and Horse Collins whispering. Mutiny? I watched the first of the robots go into the big hole that led to the elgeron deposits, and came back to see Van at the duplicate robot control board we had to use at the end of a trip. Van was looking worried, but it could have been feigned. "A few minutes?" I asked. "How many is a few?" "I said 'a couple' only, Chief, but I think that was a bad guess. It might be an hour." Horse was smiling. Van kept his face averted. "Delayed an hour?" I asked, and then it came to me. Horse wanted another look at his asteroid. That's why they'd whispered. "I'm afraid," I said, "an hour's delay would be too long, and I hope neither of you think I'm being fooled by your cute little tricks. This isn't the time for trickery." "Sorry, Chief," Van said. "I'm doing the best I can." He kept his attention on the control board and Horse bent over his charts. They ignored me. Well, I had a lot of strings to pull. They'd regret this day, both of them. The smell of molten elgeron was heavy now, and the bite of ammonia. The robots were coming back up the ramp, carrying enormous chunks of the solidified, translucent stuff. On Mars, it would be crushed in the huge, automatic grinders and mixed with the stydium of that planet, and sent in radiation-proof ships to the laboratories of Earth. One robot seemed to falter for a second, and I glanced quickly back toward the cabin where I could just see Van at the control board. I couldn't tell by his manipulation of the toggles whether the robot's falter was deliberate or not, but I saw him glance at Collins and smile.
