Advanced Small Radar Satellite Called "ASNARO-2" to be Launched by the Third Epsilon Launch Vehicle

ASNARO-2, an acronym of  "Advanced Satellite with New System Architecture for Observation,"  is an advanced small radar satellite, the development of which the Ministry of Economy, Trade and Industry(METI) has supported. METI hereby announces that Japan decided to launch the satellite by the Third Epsilon Launch Vehicle from a JAXA Uchinoura Space Center launch site on January 17(Wed.), 2018.

1. Purpose

METI has been promoting the ASNARO project, an effort for developing earth observation satellites which excel in fast delivery, high performance, compactness and low price, and aims to fortify the competitiveness of Japan’s space industry and expand its industries in which related technologies are utilized.

As part of this project, NEC Corporation has succeeded in developing a radar satellite for earth observation, i.e., ASNARO-2. In response, Japan then scheduled to launch the satellite on November 12(Sun.), 2017. However, a defect was found in an electrical system of the Third Epsilon Launch Vehicle during the inspection at the launch site. Therefore, Japan decided to postpone the launching of the satellite and has been investigating the cause and taking measures.

METI hereby announces that the measures have been completed and that on January 17(Wed.), 2018, Japan will launch the satellite using the Third Epsilon Launch Vehicle from a JAXA Uchinoura Space Center launching site.

2. Launch schedule (tentative)

Date and time:
January 17(Wed.), 2018; around 6:00 a.m. to 6:35 a.m.(Japan standard time)
