SPRINT-A SatelliteSPRINT-A Satellite

Tokyo, September 14, 2013
- The Japan Aerospace Exploration Agency (JAXA) today announced that its "HISAKI" (SPRINT-A, *1) satellite has successfully entered its intended orbit and deployed its solar array paddle (Figure 1) as scheduled.  HISAKI was launched by the first Epsilon Launch Vehicle from the Uchinoura Space Center on September 14, 2013.

NEC, under the supervision of JAXA, designed and built HISAKI. The satellite bus (*2), "SPRINT," (*3) utilized for HISAKI is a semi-made-to-order standard platform developed by JAXA. NEC contributed to the development of HISAKI with its vast experience in the development of satellites, beginning from the "OHSUMI" satellite launched in 1970. NEC also supports satellite operations, including launch preparations and the initial confirmation of functions after launch.

Going forward, NEC will continue to provide support for the first two months of operations for the one-year Spectroscopic Planet Observatory mission of HISAKI. NEC also aims to contribute to future missions that capitalize on the SPRINT satellite platform.

NEC aims to realize an information society that is friendly to people and the earth based on state-of-the-art space technologies nurtured through the development of Japan's space industry.

Please refer to the attachment for an overview and images of HISAKI.
