Launch Data of the Small Rocket Called "SS-520 No.5" to Change

Concerning the small rocket called "SS-520 No.5," successfully developed by the Japan Aerospace Exploration Agency(JAXA)based on the commission by the Ministry of Economy, Trade and Industry(METI), Japan decided to change the initially scheduled date of launching the rocket to December 28(Thur.), 2017, from a JAXA Uchinoura Space Center launch site.

1. Purpose

Expecting an increase in demand for ultra-small satellites, METI has been engaging in a Research and Development Project for Improvement of Technical Information Infrastructures for the Space Industry(On-orbit Demonstration of Space Equipment Making Use of Commercial Products). This project aims to develop small rockets, microsatellites and other space vehicles with price competitiveness in which Japan’s commercial parts and technologies are utilized.

As part of the project, JAXA initially scheduled the launching of the rocket on December 25(Mon.), 2017. However, it decided to change the schedule to December 28(Thurs.), 2017, to coordinate with the operation schedule of the Third Epsilon Launch Vehicle, from which a satellite will be launched from a JAXA Uchinoura Space Center launch site.

The SS-520 No.5 will be launched with a built-in microsatellite called “TRICOM-1R,” an achievement developed by the University of Tokyo as another effort under the project.

2. Schedule of the launching(tentative)

Date and time:
December 28(Thurs.), 2017; from 12:30 to 14:15(Japan standard time)
Note: Reserved launch period: From December 29(Fri.) to February 12(Mon.), 2018
Site:
JAXA Uchinoura Space Center(1791-13, Minamikata, Kimotsukicho, Kimotsukigun, Kagoshima Prefecture)
