Lightweight Thermal Protection Systems for Re-Entry in the New Space Era

New Space is revolutionizing access to space through private innovation, breakthrough technologies, and rapid development cycles. Spacecraft are now built on significantly shorter timelines and at lower costs. In this context, thermal protection systems—especially heatshields—are critical from the earliest stages of design, particularly for reusable vehicles.

New Space missions are typically designed for shorter operational lifespans and focus primarily on low Earth orbit. These parameters demand materials that are not only high-performance but also cost-efficient and fast to manufacture.

Atmospheric re-entry remains one of the most extreme phases of any mission, requiring materials that can endure intense thermal and mechanical loads while maintaining minimal weight and maximum reliability.

Pyroxide—a new generation alternative to oxide ceramic matrix composites (O-CMCs) developed by Pyromeral Systems – can be used as reusable thermal protection systems.

Key Advantages of Pyroxide for Space Applications:
Lightweight, ideal for replacing metal components in thermally critical areas:
Pyroxide: 2.5 g/cm³
Inconel: 8.4 g/cm³
TZM : 10.2 g/cm3
Thermal resistance up to 1300°C (2400°F)
Outstanding mechanical stability at high temperatures, thanks to consistent rigidity and modulus retention
Advanced processability, enabling the production of complex aerodynamic shapes using techniques similar to organic composite lay-up—ideal for fast, flexible manufacturing
These features make Pyroxide particularly well-suited for aero-thermal components in atmospheric re-entry vehicles, where heat resistance, reusability, weight savings, and cost control are paramount.

As part of a new generation of ceramic composite materials, Pyroxide empowers innovation across New Space programs—from reusable launch systems to return capsules and hypersonic demonstrators—perfectly aligned with the industry’s focus on speed, performance, and affordable access to space.
