SpaceX redefined the bounds of human area journey on September 12, 2024, with a history-making, first-ever non-public spacewalk throughout the Polaris Daybreak mission.

Whereas this milestone in area exploration can be remembered for years to return, one of many key highlights was the cutting-edge spacesuit expertise that made it attainable, notably the 3D-printed helmets worn by the astronauts.
Whereas pushing the boundaries of business area exploration into uncharted territory can be remembered for years, one of many standout triumphs of the mission was the spacesuit expertise that made it attainable—notably the 3D printed helmets worn by the astronauts. These helmets mark a big leap ahead, showcasing the function of superior manufacturing—particularly 3D printing—in revolutionizing area exploration gear.
This wasn’t simply any spacewalk—it was performed at roughly 700 kilometers above Earth, the very best orbit for a business mission. Such excessive circumstances demanded strong gear and the 3D printed helmet delivered. Not solely did the helmets meet the challenges of deep area, however the complete mission pushed the boundaries of what non-public spaceflight can obtain.
Polaris Daybreak was distinctive in additional methods than one. Not like conventional area missions involving astronauts stationed on the Worldwide Area Station (ISS), this mission was totally non-public. Jared Isaacman, the billionaire entrepreneur behind the Polaris Program, and SpaceX engineer Sarah Gillis stepped out of the SpaceX Dragon capsule for about quarter-hour throughout the spacewalk, a feat that pointed to the potential of personal spaceflight.
The mission occurred in low-Earth orbit (LEO), far past the ISS, setting a brand new file for the very best altitude ever reached by a crewed business spacecraft. This wasn’t only a publicity stunt; it was a real-world take a look at of SpaceX’s newly designed Additional-Vehicular Exercise (EVA) fits. These fits, a big improve from the corporate’s Intravehicular Exercise (IVA) fits, had been designed with future deep-space missions in thoughts, together with potential journeys to Mars.

The Energy of 3D Printing in Area Swimsuit Design
Produced from sturdy polycarbonate materials, these helmets had been lighter and filled with superior options that boosted the astronauts’ security and efficiency throughout their spacewalk. Vital upgrades over conventional spacesuit designs, these fits included superior visor expertise, together with a copper and indium tin oxide coating to guard towards photo voltaic glare and anti-fog remedies.
The helmet additionally features a built-in heads-up show (HUD), offering astronauts like Jared Isaacman and Sarah Gillis real-time info on vital components akin to go well with stress, temperature, and humidity. These options are essential in a spacewalk setting, the place each second and every bit of knowledge can imply the distinction between success and disaster.

Conventional spacesuits are heavy and sophisticated, which makes them arduous to make use of in area. Utilizing 3D printed components permits for quicker manufacturing and simpler customization. As an illustration, SpaceX’s new EVA go well with might be adjusted to suit completely different physique sorts, making area journey attainable for extra individuals.
That is necessary as SpaceX appears to be like to the longer term, with plans to construct bases on the Moon and even cities on Mars. These missions will want 1000’s, perhaps even thousands and thousands, of spacesuits. Growing 3D printed spacesuit components is a giant step towards making that attainable. With 3D printing, SpaceX can rapidly produce helmets and different components, chopping down on each price and time to get future area vacationers prepared.
SpaceX isn’t any stranger to 3D printing expertise. Early on, the corporate invested in Velo3D gear, which allowed for manufacturing advanced geometries that had been beforehand inconceivable with conventional strategies. Whereas rumors of SpaceX doubtlessly buying Velo3D have circulated previously, collaborations with Velo3D and different corporations continued to develop, notably for parts like rocket engines.
The corporate has been 3D printing key components of its Raptor engines, vital to missions like Starship. As well as, the Falcon and Dragon spacecraft embrace 3D printed components designed to face up to excessive circumstances, like the warmth shields used throughout re-entry into Earth’s environment.

NASA can be exploring 3D printing to advance spacesuit design. The “Spacesuit Digital Thread” undertaking goals to create customized, high-performance fits for Mars missions. Through the use of body-scanning expertise and additive manufacturing, NASA is working to make sure these fits match particular person astronauts completely, enhancing consolation and efficiency in deep-space missions. This innovation may very well be important for long-duration missions to discover different planets.
Testing the Limits of Human Spaceflight
The Polaris Daybreak crew did their spacewalk whereas orbiting by means of parts of the Van Allen radiation belt, one of the vital hazardous areas for astronauts as a result of excessive ranges of area radiation. To mitigate these dangers, the crew wore their new EVA fits, designed to supply higher safety towards environmental hazards like micrometeorites and area radiation.

SpaceX additionally used the mission to check new communication applied sciences, particularly Starlink’s laser-based communications in area. This might pave the way in which for future missions to the Moon, Mars, and past, the place dependable communication programs can be important.
Polaris Daybreak is only the start of SpaceX’s formidable plans. It’s the first of three deliberate Polaris missions. One of many long-term targets of the Polaris Program is to organize for crewed missions to Mars. To try this, SpaceX is creating scalable applied sciences like 3D printed helmets and EVA fits to create space exploration extra environment friendly and accessible.

Scientific knowledge from the Polaris Daybreak mission may have a huge impact. Researchers will research organic samples from the crew to study extra about how area impacts the human physique. That is particularly necessary for future missions to Mars, the place astronauts would possibly spend months and even years in area.
The driving drive behind SpaceX has all the time been the idea that people shouldn’t be confined to Earth however ought to discover far past. The enhancements in spacesuit expertise are an enormous step ahead for future missions. Creating fits that may regulate to completely different wants is vital to creating life on different planets attainable.
