A Japanese H-IIA rocket will launch the six optical reconnaissance in Japan’s Information Gathering Satellite System. This is the second in the third generation of optical imaging satellites orbited by the Japanese in a program initiated in 2003 to end reliance on foreign allies provided reconnaissance data to Japan, primarily dedicated to watching over North Korean missile activities.

Launch coverage:



Payload:


Not much is known about this satellite given the mission's secretive nature.
The IGS-Optical 6 (Intelligence Gathering Satellite) is the second of the third generation Japanese optical reconnaissance satellite. The satellites are operated by the Cabinet Satellite Information Center. The satellite serves both Japan's national defense and civil natural disaster monitoring.

Launch Vehicle:

H-IIA is a Japanese Launch Vehicle. It is a two-stage rocket operated by the Japan Aerospace Exploration Agency and MHI. H-IIA is built by Mitsubishi Heavy Industries. The Vehicle is capable of flying satellite missions as well as releasing spacecraft into planetary trajectories. Based on its capabilities, H-IIA is a medium-lift launcher which can place payloads in a variety of Orbits including Low Earth orbit and Geostationary Transfer Orbit. The H-IIA Rocket is being launched from the Tanegashima Space Center, Japan. Current Launches are operated by MHI only as JAXA handed the Launch System over in 2007.
