Saluting NASA on the successful mission as it progresses towards data collection phase, Microsemi cites the presence of its radiation-tolerant field programmable gate arrays from the RTSX-SU and RTAX-S product families in use within the space vehicle’s command and control systems, and in various instruments which have now been deployed and are returning scientific data. Microsemi’s high and low voltage radiation-hardened power supply modules support guidance and controls systems on board the Juno spacecraft. In addition, a broad range of Microsemi’s portfolio of high-reliability discrete diode and transistor technologies are used in many of the mission critical avionics and platform functions.


After an almost five-year journey to the solar system's largest planet, the spacecraft successfully entered Jupiter's orbit; over the next few months, Juno's mission and science teams will complete the transition to the final 14-day science orbit and initiate formal collection of scientific data.


“We are honored yet again to support NASA’s mission as we leverage Microsemi’s nearly 60 years of experience providing high-reliability semiconductor solutions for groundbreaking U.S. space programs,” said James J. Peterson, chairman and CEO of Microsemi. “This demonstrates the high quality of our radiation-tolerant and radiation-hardened products, as well as our commitment to our space customers who depend on our expertise to complete their missions even in the most hostile and inhospitable environments.”

Microsemi adds that it has been providing space solutions for a variety of U.S. space programs dating back to the launch of the first Atlas rocket in 1957. The company continues to develop new products and technology for future missions as part of its broad portfolio of radiation-hardened and radiation-tolerant products, expanding its ability to cater to the needs of a growing spacecraft market. www.microsemi.com
