November 13, 2017 (JST)
National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)
The Japan Aerospace Exploration Agency (JAXA) will conduct a demonstration experiment of a microsatellite launch by SS-520 No. 5 as follows.
- Experiment Period:
- December 25 (Mon.), 2017 thru January 31 (Wed.), 2018
- Experiment site:
- Uchinoura Space Center (Kimotsuki-cho, Kimotsuki-gun, Kagoshima Pref. Japan)
- Scheduled experiment date and time:
- Between 10:00 to 14:15 on December 25 (Mon.) , 2017 (Japan Standard Time)
- Description of experiment:
- In response to the failure of SS-520 No. 4 experiment in January this year, a retry demonstration will be held for the development of rockets and satellites using civil engineering technology. The experiment has been approved by the Ministry of Economy, Trade and Industry, as part of its SERVIS project (Space Environment Reliability Verification Integrated System).

TRICOM-1R is a new generation satellite, that is produced based on the nanosatellites Hodoyoshi No. 3 and 4., which are approved by the Ministry of Economy, Trade and Industry as part of its SERVIS project (Space Environment Reliability Verification Integrated System). The Experiment Team is planning to operate the TRICOM-1R for the following missions.
-Store and Forward mission, where TRICOM-1R stores data transmitted from the ground and forwards data to the ground as the satellite positions above the ground control.
- Take photographs of the Earth with its onboard camera.
- Immediate observation mission which autonomously carries out observations of the Earth immediately after the launch and the insertation into the orbit, and sends the observation data to the ground upon the first communication with the ground station.
