The Helmet assembly is now in Phase B, Concepting & Definition. The helmet provides astronauts with communication, oxygen, a clear view of the environment and protection against harsh conditions during EVA¹.
The Helmet assembly must meet several requirements to ensure the safety and comfort of the astronauts. These requirements include:
- Visibility: Without clear visibility an astronaut’s ability to navigate and perform tasks outside of the spacecraft would be severely impaired, and it could even lead to dangerous situations.
- Anti-fog: An anti-fog feature is essential as the temperature inside the helmet can quickly rise, causing the visor to fog up, and impairing visibility. An anti-fogging mechanism could be a chemical coating on the visor that prevents moisture buildup or a small fan that circulates the air inside the helmet.
- Oxygen: The spacesuit helmet is equipped with an oxygen filtration and conservation system that filters out carbon dioxide and other contaminants and provides a continuous supply of fresh oxygen to the astronaut.
- Protection: Space is full of hazards, including radiation, micrometeoroids, and extreme temperatures, the helmet should withstand significant impacts and provide an airtight seal to protect the astronaut’s head.
- Communication: The helmet is equipped with an integrated communication system that allows astronauts to talk with each other.
