The EVA-3 concept emerged from a collaboration between NASA, the European Space Agency (ESA), and a team of private aerospace engineers. The primary objective was to develop a spacecraft capable of withstanding the harsh conditions of atmospheric reentry, while also ensuring the safety and comfort of its occupants. The EVA-3's design and development phase involved extensive research, simulation, and testing, drawing on expertise from various fields, including materials science, aerodynamics, and propulsion systems.
One of the most significant challenges in designing a spacecraft like the EVA-3 is the extreme heat generated during atmospheric reentry. As the spacecraft encounters the dense layers of the atmosphere, it must withstand temperatures exceeding 2,000°C, while also maintaining a stable and controlled descent. The EVA-3's thermal protection system (TPS) is designed to address this challenge, comprising a combination of ablative materials, ceramic tiles, and advanced composites.
