This chapter details the construction and outfitting of the projectile vehicle designed to carry the three adventurers to the Moon, focusing on its shock-absorbing water bed, airtight features, and life-support systems including oxygen regeneration and carbon dioxide removal. It also recounts the trial of the air renewal system by J. T. Maston, who voluntarily sealed himself inside the projectile for a week to test its viability, emerging healthy and even having gained weight.
The travelers aboard the projectile awaken to tend to their injured dog and observe the changing phases of Earth and the Moon, reflecting on their unique position in space. They experience the intense solar radiation warming their craft, manage air quality challenges, inspect their supplies and instruments, and contemplate the breathtaking celestial views as they continue their lunar journey.
