CHALLENGE The EMIT mission maps the surface mineralogy of arid dust source regions and aids in improving forecasts of the role of mineral dust in the warming and cooling of Earth's atmosphere. Since the Earth Imaging Spectrometer used in this mission generates large amounts of high-quality data and will launch in a harsh environment exposed to radiation, JPL requires a reliable, radiation-tolerant storage device with high-speed data processing and large storage capacity. SOLUTION Mercury delivered the high-performance RH3440 solid-state data recorder with proven reliability in high-radiation environments to enable on-orbit sensor data processing and storage. The innovative microprocessor and software-free design provides precise, long-term operation in harsh environments, such as Earth's atmosphere. RESULT With extremely reliable, advanced Serial RapidIO (SRIO) technology and Mercury's proprietary horizontal error correction for data integrity, Mercury's SSDRs allow JPL to transfer significantly more data in less time, resulting in a more efficient system. The RH3440 helps JPL map the composition of areas that produce mineral dust, supporting the EMIT mission's advanced understanding of dust's effects on Earth's atmosphere and human populations now and in the future. EMIT is scheduled for launch to the International Space Station (ISS) in 2022.
