TOKYO, Japan – Renesas Electronics Corporation announced its radiation-hardened integrated circuits (ICs) are crucial components for NASA's Artemis II mission, which successfully launched on April 1, 2026, from Kennedy Space Center in Florida. The mission marks the first time astronauts are flying aboard the Orion spacecraft and the first crewed lunar flyby in over 50 years. Renesas' specialized chips ensure critical systems operate reliably in the harsh environment of deep space.
Robust Technology for Deep Space
Renesas' Intersil-branded radiation-hardened ICs are embedded across the core systems of Artemis II. These include both the Orion capsule and the powerful Space Launch System (SLS) rocket. The chips perform vital functions like regulating and distributing power, maintaining signal integrity, and supporting onboard computing.
Space missions expose electronics to extreme radiation and temperatures. Renesas designs these specialized ICs to withstand these conditions. This ensures continuous and reliable performance for mission-critical operations.[ien+3]
Chris Stephens, Vice President of the HiRel Business Division at Renesas, highlighted the demanding nature of space travel. "Human space flight missions leave no margin for failure," Stephens said. "We're proud to be one of the select few semiconductor companies entrusted to provide space-qualified technology for this historic crewed Artemis mission."[ien+2]
Decades of Spaceflight Heritage
The Intersil brand, now part of Renesas, boasts a long history in the space industry, spanning more than six decades. Its involvement began with the founding of Radiation Inc. in 1950. Since then, Intersil-branded products have been part of almost every satellite, shuttle launch, and deep-space exploration mission.
Renesas leverages this extensive experience to deliver highly reliable products for defense and space markets. The company offers over 400 space-qualified radiation-hardened products. These components undergo rigorous design and manufacturing processes in Renesas' MIL-PRF-38535-qualified facility in Palm Bay, Florida. This meticulous approach ensures predictable performance and prevents system failure during long-duration missions.[renesas+4]
Artemis II: A Gateway to Lunar Return
Artemis II is a 10-day crewed lunar flyby mission. Four astronauts are now traveling aboard NASA's Orion spacecraft, going farther from Earth than humans have gone in over fifty years. The mission's primary goal is to test spacecraft systems and crew performance in deep space.
This flight is a critical step in NASA's broader Artemis program. The program aims to return humans to the Moon and establish a long-term presence on the lunar surface. Future missions, like Artemis III, plan to land the first woman and first person of color on the Moon.[ien+4]
The Orion spacecraft and the Space Launch System rocket are central to these ambitious plans. The success of Artemis II will validate key capabilities for upcoming crewed journeys and lunar landings.[renesas+5]
The integration of advanced, radiation-hardened electronics from specialized suppliers like Renesas is vital for the safety and success of these complex human spaceflight endeavors. Such technology allows astronauts to venture further into the solar system, paving the way for future exploration of the Moon and eventually Mars.[ien+4]
