The crew of the Skylark try to use their newly invented space suits, which have never been actually tested in the field DuQuesne reported briefly to the two girls.

All three put on space-suits and crowded into the tiny airlock.

Introduction

The lock was pumped down. There was a terrific jar as the two ships of space were brought together and held together. Outer valves opened; residual air screamed out into the interstellar void.

Moisture condensed upon glass, rendering sight useless. We'll have to go by feel.

In case of a hull breech, the pressure regulating tubes in the seam will inflate to put the suit under tension, and the astronaut will put on the emergency oxygen mask.

Artwork by Fred Freeman. Worn on Space Shuttle only during ascent and entry portions of flight. Partial- body soft pressure-suit To recap: Partial Pressure suits only pressurize certain parts of the body for a limited time. They are only used as a precaution, worn inside the habitat module during times when there is danger of it springing a leak, such as during lift-off or if an enemy spacecraft is shooting at you.

Partial pressure suits are a trade-off: The image above from First Men to the Moon is a partial pressure suit based on an old school Air Force high-altitude suit.

If the pressure drops, the pressure regulating tubes along the suit's seams inflate to put the suit under tension. The wearer will then put on the oxygen mask attached to the small tank strapped to their leg. The crew of a combat spacecraft in battle probably will not wear a soft, hard-shell, or semi-rigid suit during battle.

This is for the same reasons that the crew of a military submarine do not wear SCUBA gear in battle even though they too are in a craft surrounded by countless miles of unbreathable stuff while being shot at.

It gets in the way. But they might wear a partial- body pressure suit or a skintight pressure suit.
