NASA’s Artemis II mission has successfully launched from the Kennedy Space Center, marking the first time in decades that a crewed spacecraft is en route to orbit the moon. Central to the operation of the Orion spacecraft and the Space Launch System (SLS) rocket are radiation-hardened (rad-hard) integrated circuits (ICs) developed by Renesas Electronics Corporation.
These specialized components are embedded deep within the vehicle’s avionics and safety launch systems. In the harsh environment of deep space, where electronics are subjected to extreme temperatures and elevated radiation levels, these ICs perform essential functions including power distribution, voltage regulation, and the maintenance of signal integrity for onboard computing systems. The mission serves as a critical validation of these spacecraft capabilities, ensuring systems remain operational as the four-person crew tests performance far beyond Earth’s orbit.
The technology utilized in Artemis II falls under the Intersil brand, which has provided components for nearly every major satellite and deep-space exploration mission since 1950. These products are manufactured to meet stringent standards, including SMD, MIL-STD-883, and MIL-PRF 38535 Class-V/Q, specifically for the defense and high-reliability space markets. Beyond power conditioning, the devices support mission-critical subsystems for data communications, general protection circuitry, and telemetry, tracking, and control (TT&C).
“Human space flight missions leave no margin for failure, and we’re proud to be one of the select few semiconductor companies entrusted to provide space-qualified technology for this historic crewed Artemis mission,” said Chris Stephens, Vice President of the HiRel Business Division at Renesas. “Our rad-hard devices help keep spacecraft systems connected, protected and precisely controlled, as crews venture into deep space. We look forward to supporting future landmark missions and ushering in the next era of solar system exploration with our space‑grade semiconductor solutions.”
As a global provider of microcontrollers and analog solutions, Renesas continues to integrate embedded processing and connectivity expertise into infrastructure and aerospace applications. The successful deployment of these ICs on Artemis II positions the technology for future crewed journeys and long-term lunar surface habitation.
