They moved slowly at first. Glen hoped for only enough speed to carry them into Mars’ gravity pull. As they approached the red planet, their speed would increase and that worried Glen. If they whacked into Mars’ air blanket too fast, the chute might be ripped from the bubble.

To while away the many hours, the boys dozed and took turns reading the one novel they had brought along. Their legs soon became cramped and sore, and they would have given a good deal to have been able to stretch or walk about.

On the third day, the boys could see the canals criss-crossing in a tangled network on the ruddy globe of Mars. On the fourth day, just as Glen had figured, the glassite domes of Mars City began to show through the violet haze of atmosphere. Glen wondered how fast they were going. There was no way to tell because their insulation kept them from feeling the rush of air.

“Cross your fingers, Skip,” Glen warned. “Our chute should open in the next few minutes.”

The seconds appeared to last hours as they waited, and Glen suffered a torture of suspense. What if the chute did not open? In that case, they would end up in fragments on Mars’ red earth. Or what if the force of the air should jerk the chute off the bubble?

Even as Glen worried, he felt a sharp drag and was tumbled over on Skip.

“Look! The chute’s open!” Skip pointed overhead.

Some minutes later, the red ground rushed up at them like an enfolding blanket. Their final problem faced them now. If they landed safely, they would have conquered space in a way no spaceman had ever done before.

Glen’s muscles drew tight and his heart thumped rapidly as the last few hundred feet melted away. He wanted to close his eyes during these final seconds but he forced himself to watch the rising ground so that he could brace himself at the moment of contact. He was glad they had the foam rubber cushion beneath them.

Glen counted off the last few feet. “A hundred—fifty—twenty—!”
