SpaceX Unveils New Streamlined Spacesuits

SpaceX has unveiled its latest Extravehicular Activity (EVA) suits, which could debut in low-Earth orbit by the end of summer. These new suits represent an evolution from the current Dragon mission spacesuits, limited to pressurized environments. Unlike their predecessors, the EVA suits enable astronauts to operate both inside and outside the capsule, boasting advancements in materials, joint design, redundancy measures, and the incorporation of a helmet visor heads-up display (HUD).

Pioneering the Polaris Program: Unveiling the Future of Human Spaceflight

Over the weekend, SpaceX announced that the EVA suits will outfit the four crewmembers assigned to the Polaris Program’s inaugural mission, Polaris Dawn. Launched initially in 2022, the Polaris Program, a collaborative effort with SpaceX, aims to advance human spaceflight capabilities rapidly. Scheduled for no earlier than summer 2024, Polaris Dawn will mark several milestones, including the first commercial spacewalk and the first spacewalk involving four astronauts simultaneously. While venturing beyond their Dragon capsule, the crew will also pioneer testing Starlink’s laser-based communications systems, a technology SpaceX deems crucial for future missions to the moon and Mars.

Innovations in Space Apparel: Materials, Mobility, and Accessibility

SpaceX’s teaser video, shared on X on May 4, underscores mobility as its central theme, featuring an EVA suit wearer demonstrating fluid movements of fingers, shoulders, and elbows. As outlined by PCMag.com on Monday, these suits are crafted using a range of textile-based thermal materials and incorporate semi-rigid rotator joints, facilitating tasks in both pressurized and unpressurized settings. Additionally, the boots utilize the same temperature-resistant material employed in the Falcon 9 rocket’s interstage and the Dragon capsule’s trunk.

Astronauts aboard Polaris Dawn will don 3D-printed polycarbonate helmets featuring visors coated in copper and indium tin oxide, treated for anti-glare and anti-fog properties. As they conduct the spacewalk approximately 435 miles above Earth, each crewmember’s helmet will integrate a built-in heads-up display (HUD), offering real-time pressure readings, temperature, and relative humidity.

SpaceX’s EVA suit, like Prada’s Artemis III design, aims for a future with inclusive space fashion. Their adaptable design allows customization for various body types, a step towards wider space access. Millions of suits for Mars may seem far off, but every journey starts with a few.
