The extra radiation might put both of them well over the safety limits
long before Earth was reached, and they both knew it. He reached the
crater's edge and walked right down into it.
They were out of sight of the Connies now. Rip walked up the other side
of the crater until his bubble was just below ground level. The chunks of
thorium he had ordered thrown in to block some of the radiation made
walking a little difficult.
"Santos," he said, "we're in the second crater."
"Sir, I'm beyond the first, between two crystals. Pederson is near you
somewhere."
"Good. When I give the word, turn up your helmet light until they can see
a pretty good glow. Keep watching them." The bubbles were equipped with
lights, but they were seldom used. He outlined his plan swiftly. Both
Santos and Dowst acknowledged.
Koa reported in. "We're after two more Connies near the wreck of the
landing boat, sir."
"Be careful. Pederson, go help Koa. Nunez, how are things at the cave?"
"Nunez reporting, sir. Two Connies in sight, but they haven't seen us
yet."
"Let me know when they spot the cave."
"Yes, sir."
"Santos, go ahead."
For long moments there was silence. Rip felt for a solid foothold, found
one, and flexed his knees. He kept his back straight and his eyes on the
crater rim. His hands were occupied with two air bottles taken from his
belt, and his thumbs were on their valve releases. He waited patiently
for word from Santos that his helmet glow had been seen.
