Layers of Light and Shadow

Dialogue Between Worlds


Thermal shielding: reflecting radiation to protect instruments in space.

Scientists Tell Their Story

Observing from Space

Space instruments face extreme conditions: in orbit, temperatures can swing from -150°C in shadow to +120°C in direct sunlight. Thermal control systems, including multilayer insulation and reflective coatings, are essential to maintain operational stability. These layers reflect solar radiation and limit heat loss, allowing sensitive instruments to function and collect precise data over long missions.

Multilayer thermal blankets consist of alternating layers of reflective and insulating materials. Each layer reduces radiative and conductive heat transfer, providing a finely tuned balance between protection and mass. Payloads such as cameras, spectrometers, or particle detectors rely on this shielding to survive and operate in the harsh environment of space.

This technology is crucial for Earth-observing satellites, astrophysical missions, and exploratory spacecraft. By controlling the flow of heat and radiation, thermal shielding enables scientists to measure and observe phenomena without interference from environmental extremes.

INVAP: Engineering Innovation from Argentina

INVAP is an Argentine company renowned for its high-technology engineering and research projects. Founded in 1976, it has designed and built satellites, nuclear reactors, and scientific instruments that are used both nationally and internationally. Its work combines cutting-edge physics, precision engineering, and project management to deliver highly specialized solutions.

In the realm of space technology, INVAP has developed satellites for Earth observation, communication, and scientific missions. Each satellite integrates advanced thermal, power, and instrumentation systems, reflecting the company’s expertise in transforming complex scientific requirements into operational, reliable hardware.

By bridging research and industry, INVAP illustrates how a national technology company can contribute to fundamental science, space exploration, and advanced technological development.

The Designer Lends His Voice

Layers of Light and Shadow transforms the concept of thermal protection into wearable art. The suit — a metallic jacket and trousers — is crafted from the same multilayer material used to shield satellites in orbit. Its reflective surface evokes both sunlight and shadow, making the invisible physics of space tangible.

Pockets throughout the design reference satellite payloads, while the interplay of reflective and textured surfaces mirrors the careful balance between insulation and exposure. By translating technical solutions into a visual and tactile experience, the suit invites viewers to explore the hidden mechanics that safeguard scientific exploration.
