Renesas Electronics has contributed to iconic missions such as NASA’s Artemis I, Mars 2020 Perseverance Rover and JAXA’s Hayabusa2. It also supports Low Earth Orbit (LEO) missions with a new line of rad-tolerant products—striking a balance between performance and cost.
Renesas in NASA’s Artemis I Mission
The Artemis I Moon mission demanded electronics that could withstand deep-space radiation and extreme environments.
Renesas provided:
- Radiation-Hardened Microcontrollers (RH850):
Ensured avionics and control systems operated without failure, preventing latch-up and SEUs.
- Rad-Tolerant Power ICs:
Delivered efficient and stable energy to critical systems—navigation, communication, and life support.
Mars 2020 Perseverance Rover
Mars missions face harsh temperatures and radiation. Renesas supported NASA’s rover with:
- Advanced Sensor Technologies:
Captured Martian temperature, pressure, and chemical data. Powered SHERLOC, which detects signs of microbial life. - Radiation-Hardened Data Processing ICs:
Handled real-time analysis and robotic control under extreme conditions.
JAXA’s Hayabusa2 Asteroid Mission
Hayabusa2 collected and returned asteroid samples. Renesas played a key role in:
- Navigation with Low-Power RL78 MCUs:
Enabled precision maneuvers and trajectory corrections with minimal energy use.
- Reliable Deep-Space Communication:
Radiation-tolerant transceivers ensured consistent data transmission with Earth.
Expanding Horizons: Renesas in LEO Missions
LEO missions, like Earth observation and telecom satellites, demand efficiency. Renesas responded with:
New Rad-Tolerant product line
- Rad-Tolerant MCUs:
Built on commercial-grade platforms with balanced radiation resistance and power efficiency.
- Advanced Power Management ICs:
Deliver stable energy in radiation-heavy LEO environments to prolong satellite lifespan.
Conclusion
From the Moon to Mars to LEO, Renesas continues pushing space tech boundaries. Their suite of radiation-hardened and -tolerant solutions is enabling:
- Deep-space missions
- High-performance LEO constellations
- Greater mission reliability and cost-efficiency
Renesas is not just supporting space technology—it’s shaping its future.
