Tokyo, March 13, 2018 - NEC Corporation (NEC; TSE: 6701) today announced the successful reception of images from its high-performance compact radar satellite, ASNARO-2, including images of a volcanic eruption in the Kirishima mountain range (Mount Shinmoe) in southwestern Japan. Images are scheduled to be available for public sale starting this September.

ASNARO-2, was launched on January 18, 2018 with the Epsilon rocket-3, the third Epsilon launch vehicle, and is currently flying at an orbital altitude of approximately 500 km while completing a full orbit of the Earth roughly every 90 minutes.

The first images were taken from ASNARO-2 as it flew over Europe on February 4, 18 days after its launch. Although the images were taken at sunset, rural areas, vegetation and the condition of roads and rivers are clearly visible. Even the maturity of crops can be determined based on variations in their levels of brightness.

On March 1, Mount Shinmoe in southwestern Japan experienced a small eruption, and images of the surrounding area were taken in emergency observations on March 4 and March 10. ASNARO-2's radar sensor successfully captured details of ground conditions, such as the movement of lava around the crater, even as it was obstructed by smoke, which is difficult for conventional optical sensors to observe.

"Going forward, NEC will continue to refine calibrations in order to further improve the quality of images taken from ASNARO-2," said Kunio Kondo, Senior Vice President, NEC Corporation. "Following the official start of the NEC Satellite Operation Center in April of this year, we aim to launch an image sales service in September as part of the Center's space utilization service business."
