Astro signaled that he could and stepped through the hatch. He turned, and facing backward, began clawing his way upward.
"Keep that hose clear, Roger!" ordered Tom. "There's about five feet of sand that he has to dig through and if any of it gets into the hose—well—"
"Don't worry, Tom," interrupted Roger. "I've got the end of the hose right next to the oxygen bottle. He's getting pure stuff!"
Soon the big cadet was lost to view. Only the slow movement of the hose and rope indicated that Astro was all right. Finally the hose and rope stopped moving.
Tom and Roger looked at each other, worried.
"You think something might be wrong?" asked Tom.
"I don't know—" Roger caught himself. "Say, look—the rope! It's jerking—Astro's signaling!"
"He made it!" cried Tom.
