SHIKISAI Observation Data Acquired by SGLI

JAXA has released some observation images on the Earth acquired by the Global Changing Observation Mission - Climate "SHIKISAI" (GCOM-C). The SHIKISAI was launched from the Tanegashima Space Center at 10:26:22, 2017 (Japan Standard Time). These images are obtained by using the test radio wave transmitted from GCOM-C/SGLI on January 1st to 6th, 2018 (JST).

SHIKISAI and TSUBAME critical operation phase successfully completed! Initial function verification starts!

JAXA received telemetry data from SHIKISAI and TSUBAME, confirming that their satellite attitude control system had transitioned to the steady state. Current status of both satellites is stable.
Subsequently, the following procedure occurred - power generation that supports the satellites’ operation by the deployed solar array wings, ground communications and sound attitude control that maintains those operations. Combined by the completion of the series of other operations, such as powering up of the bus and mission equipment, the satellites have entered the state where they can be sustained in orbit. This concludes their critical operations phase.
SHIKISAI and TSUBAME will take about three months to verify the function of its onboard equipment and instruments in space.

Successful Launch, H-IIA Launch Vehicle No. 37 Encapsulating SHIKISAI and TSUBAME

The H-IIA Launch Vehicle No. 37 with the Global Changing Observation Mission - Climate "SHIKISAI" (GCOM-C) and the Super Low Altitude Test Satellite "TSUBAME" (SLATS) onboard lifted off at 10:26:22 a.m. on December 23, 2017 (Japan Standard Time) from the Tanegashima Space Center.
The launch and flight of H-IIA F37 proceeded as planned. So did the separation of SHIKISAI and TSUBAME, which was confirmed respectively at approximately 16 minutes and 13 seconds and 1 hour and 47 minutes 59 seconds after liftoff.

H-IIA F37 with SHIKISAI/TSUBAME onboard to be launched on December 23

The launch schedule of the H-IIA Launch Vehicle No. 37 (H-IIA F37) has been decided to be between 10:26:22 thru 10:48:22 a.m. on December 23 (Sat), 2017 (Japan Standard time). The launch will be performed by Mitsubishi Heavy Industries and JAXA.
H-IIA Launch vehicle No. 37 incorporates JAXA's newly developed outcome to insert SHIKISAI and TSUBAME into different orbit altitude respectively. It will expand opportunities of multiple satellite launch and take full advantage of the capability of H-IIA.

GCOM-C renamed SHIKISAI

JAXA had the public come up with an excellent nickname for the Global Change Observation Mission – Climate (GCOM-C) for almost a month. The GCOM-C nickname project was couple with SLAT’s. The project was met with quite a response – 12,895 applications. As a result of careful examination, SHIKISAI, meaning colors in Japanese was chosen.
JAXA appreciates all for positive participation.
SHIKISAI most appropriately describes the GCOM-C features – the onboard Second-Generation Global Imager (SGLI) captures a broad spectrum of objects, including flourishing vegetation, deep blue oceans, and crystal sea ice on our color-filled planet.
Updates on the SHIKISAI missions are available on this website. JAXA appreciates continuous support by all.

GCOM-C Completes Environmental Testing

JAXA’s GCOM-C satellite, Global Change Observation Mission – Climate, to be launched in Japanese fiscal 2017, undergoes environmental testing at the JAXA Tsukuba Space Center. Environmental Test flow includes sinusoidal vibration and acoustics, which JAXA collectively calls mechanical and environmental testing. The testing, which aims at ensuring that the satellite will endure rigorous shock and sound pressure during ascent, was conducted in March and April, 2017 (Image) and came to successful completion.

GCOM-C is entering electrical testing, which will determine if the satellite systems, after being subjected to environmental testing, operate properly.

Global Change Observation Mission – Climate (GCOM-C) mission logo

A mission logo for the Global Change Observation Mission – Climate (GCOM-C) has been selected. GCOM-C is a satellite mission to clarify the climate change mechanism such as global warming, as well as to monitor the status of flying yellow sand, and to observe ocean plankton to estimate fishing points by acquiring various data on the Earth that is considered to have an impact on climate change.
The design of the GCOM-C mission logo is a simplified drawing of clouds, dust in the atmosphere (aerosols), vegetation (forests), snow ice, and ocean. The evergreen color, which is a traditional Japanese color, was selected for the basic color of the logo. The color shows our desire that the mission will constantly thrive for a long time like leave colors of evergreen trees such as Japanese pines and cedars.
GCOM-C is under development to be ready for launch in JFY 2016.

GCOM-C1 structural model sinusoidal vibration test

JAXA conducted a sinusoidal vibration test for the GCOM-C1 using a structural model. This test using simulated vibrations verifies if the satellite’s structure and onboard equipment can bear sinusoidal vibrations, which are generated at the time of launch. The test was successful, and we confirmed that the satellite is strong enough. The structural model is a mechanically mocked satellite for verifying the tolerance of the satellite’s main body and onboard equipment not only against sinusoidal vibrations at the time of launch, but also against other factors including the acoustic environment, shock at the time of separation from the launch vehicle, and impact of the solar array paddle deployment.

Symposium of "Expectations to the Climate Change Monitoring using Earth Observation Satellites"

The Japan Aerospace Exploration Agency (JAXA) is holding a symposium titled "Expectations for Climate Change Monitoring using Earth Observation Satellites" on April 15, (Thursday) 2010, at the Hotel Pacific Tokyo.
Earth observation satellites have been playing an important role in monitoring climate change, and international cooperation is imperative for global-scale monitoring as a multiple number of satellites and various kinds of onboard observation sensors are required to cover the globe. JAXA has been planning to fulfill its international responsibilities for its satellites including the Greenhouse Gases Observing Satellite "IBUKI" (GOSAT) and the Global Changing Observation Mission (GCOM).
At the symposium, representatives of space and meteorological organizations from all over the world will introduce their climate change monitoring initiatives by earth observation satellites, then explain how their activities have been promoted through international cooperation. We will also discuss future prospects for international collaboration. We are looking forward to your participation.
