For instance, in July 2023, Sidus Space announced plans to include a SOLAR MEMS star tracker on its fourth LizzieSat mission. Star trackers are vital for determining a satellite's orientation and position in space. SOLAR MEMS, known for its sun sensor technologies, designed this autonomous device to capture star constellation images, improving the accuracy of the satellite's orientation data relative to Earth.
 

The space sensors and actuators market is advancing towards miniaturization, improved functionality, and increased reliability to meet the demands of modern space missions. Governments and private companies are ramping up investments in deep-space missions to explore Mars, asteroids, and other celestial bodies. These ambitious ventures require high-performance sensors and actuators for various applications, including thermal control, telemetry, and engine valve control.
 

The demand is particularly high for sensors like spectrometers and humidity/temperature sensors, which are crucial for environmental monitoring in space. As these missions become more complex and frequent, the need for advanced, reliable sensing technologies continues to grow, driving innovation in the space exploration sector.
