Launch

edit

Himawari 9 was launched on 2 November 2016, 06:20:00 UTC, atop a H-IIA rocket flying from the Yoshinobu Launch Complex Pad 1 at the Tanegashima Space Center, and by 11 November 2016 it reached to the geostationary point at 140.7 degrees East.[3] After initial function tests, it was put on standby until 05:00 UTC by 13 December 2022, when it succeeded Himawari 8.[4][5]

The launch was scheduled initially on 1 November 2016, but postponed for one day due to the bad weather forecast.

At launch, the mass of the satellite is about 3,500 kilograms (7,700 lb). It has a design life of 15 years with 8 years of operational life. Power is supplied by a single gallium arsenide solar panel, which provides up to 2.6 kilowatts of power. The main instrument aboard Himawari 9 is a 16 channel multispectral imager to capture visible light and infrared images of the Asian-Pacific region.[6]

As part of an outreach project organized by the Young Astronauts Club Japan the launch also carried manga artwork drawn by Chūya Koyama, author of the Space Brothers manga.[7]
