Nick nodded, shot an impatient glance at the others straggling up the slight incline. Together he and Dorothy mounted the acclivity, peered anxiously at the sweep below.

A little scream of delight came from Dorothy’s lips, “There, Nick!”

No doubt about it. The lost Orion lay, partly concealed by upcroppings of rock, less than a mile away. Hastily they made their way down the decline, ran in awkward, elephantine steps toward it. As they approached they could see how beaten and scarred it looked.

They bounded to the port and breathlessly clanged upon it. It was shut tightly. Impatiently they beat upon it until finally it swooshed open and they filed into the airlock. Imperturbably the outer door snapped close behind them, clamlike, and painfully slow the inner port dragged itself open.

The lost Orion!

The air was pure—that they noticed first of all when they had doffed cautiously their helmets. Pure and warm. Quickly they took off the clumsy suits and looked about them. No one was in sight; no greeting came to them.

“Hello!” yelled Nick.

No answer.

It was not as large as the Columbia, this ill-fated craft, but a big ship nonetheless. Hearts beating out ill omens, they searched room after room, finding no one.

“Hello! Hello!” cried Dorothy. Edgar grasped her arm. “Wait,” he murmured. “I think I heard an answer.”
