Observing All Environmental Changes on Earth for Present and Future Generations

The "Global Change Observation Mission" (GCOM) aims to construct, use, and verify systems that enable continuous global-scale observations (for 10 to 15 years) of effective geophysical parameters for elucidating global climate change and water circulation mechanisms.
The GCOM mission is a two series of satellites, GCOM-W for observing water circulation changes and GCOM-C for climate changes. The GCOM-W with a microwave radiometer onboard will observe precipitation, vapor amounts, wind velocity above the ocean, sea water temperature, water levels on land areas, and snow depths.
The GCOM-W1 is the first satellite for the GCOM-W series.



World's Largest Revolving Space Antenna AMSR2

The Advanced Microwave Scanning Radiometer 2 (AMSR2,) which will be loaded onto the GCOM-W1, is a sensor to observe radiometers, or microwaves emitted naturally from the ground, sea surface and atmosphere, using six different frequency bands ranging from 7 GHz to 89 GHz. The strength of a natural microwave is determined by its characteristics and moisture, including the surface condition and temperature of the material. Although it depends on the frequency, the microwave is very weak. AMSR2 will detect such weak microwaves at an altitude of 700 kilometers and measure the strength of them with a very high accuracy. For example, by measuring the strength of a microwave emitted from the sea surface with the AMSR2, we can understand the water temperature of the sea surface to an accuracy of 0.5 degrees Celsius.
The antenna of the AMSR2, which receives microwaves from the ground, arc scans the ground surface at a ratio of one turn every 1.5 seconds and observes an area approximately 1,450 kilometers wide in one scan. Using this scanning method, the AMSR2 can observe over 99 percent of the Earth's area in just 2 days. The diameter of the antenna is about 2 meters, making it the world's largest observation sensor aboard a satellite. The height of the rotating part is about 2.7 meters and the weight is about 250 kilograms. The AMSR2 can keep rotating such a large and heavy antenna at a speed of one turn per 1.5 seconds for 24 hours a day and more than five years without a minute of rest.

SDS-4 revealed to the media

On Jan. 10, the Small Demonstration Satellite-4 (SDS-4) was shown to the media at the Tsukuba Space Center.
The SDS-4 is a tiny 50-cm cubic satellite, and it will be launched as a piggyback payload with the Global Change Observation Mission 1st- Water "SHIZUKU"in Japan Fiscal Year 2012.

Overview


JAXA has been promoting the Small Demonstration Satellite (SDS) program in order to verify new technologies for components and devices in space prior to providing highly established technology to practical satellites and scientific probes.
An SDS can be developed in a shorter period of time with lower costs compared to a large-size satellite, thus it has an advantage to carry out on-orbit verification and experiments in a timely manner. In addition, we can also foster younger employees by offering them opportunities to experience an overall series of work from a design phase thru satellite operation in space.
The first SDS (SDS-1), which was about 100 kgs, was launched on January 23, 2009. The SDS-4 project aims to develop a 50-kg class satellite, which is a standard size for a companion payload on the H-IIA Launch Vehicle, and the satellite is scheduled to be launched with the SHIZUKU (Global Change Observation Mission 1st – Water, GCOM-W1) as a piggyback payload.

«Four missions of the SDS project»

-Space based Automatic Identification System Experiment (SPAISE)
To demonstrate the function and performance of the future onboard automatic identification system (ASI) receiver system, then to evaluate actual receiving data for possible interference, and to acquire knowledge for the future system structure and receiver function improvement.

-Flat Heat Pipe (FHP) On-orbit Experiment (FOX)
To assess the special features of the flat heat pipe (FHP) on orbit, then to compare them with ground test results and theoretical models, and to acquire data for practical use of the FHP.

-In-flight experiment of space materials using THERME (IST)
To acquire on-orbit degradation data of the solar absorption rate (αs ) of the thermal insulation material, which is an important feature of the material, by measuring temperature data using the "THERME" material, which was developed by CNES (Centre National d'Etudes Spatiales.)
    Quartz Crystal Microbalance (QCM)
    To gain on-orbit operation experience of a high-quality onboard quartz crystal microbalance that is domestically manufactured and less expensive while measuring contamination (gas and particles on the surface of the satellite) throughout the satellite operation including its assembly, transportation, launch site work, and on-orbit operations.

In addition to the above missions, we also aim to establish a standard bus for a 50-kg class small satellite that conducts a regular three-axis attitude control, and also research a more efficient satellite development method based on the development knowhow acquired through the SDS-1 project.

Подскажите, пожалуйста, (те, кто в СОТР разбирается), у нас или у американцев плоские тепловые трубки есть? Есть ли преимущества?

P.S. По поводу иностранных языков - а чего плохого в английском? Он требует на 30% меньше места, чем русский, хорошо рисуется (не надо иероглифы учить). Сетевые переводчики сейчас вполне неплохо работают (могу судить по японско-английским только по стройности выхода, про точность сказать не могу, так как кроме как считать до десяти по-японски ничего не знаю).

SHIZUKU mated with the Payload Attach Fitting

On April 26, the Global Change observation Mission 1st-Water "SHIZUKU" was mounted onto the payload adapter called the "Payload Attach Fitting," or PAF, at the Spacecraft and Fairing Assembly Building at the Tanegashima Space Center. The PAF is a connection part between the satellite and the launch vehicle. The launch site operations are smoothly in progress, and the SHIZUKU will be covered by the fairing and loaded onto the launch vehicle.

SHIZUKU to be launched next weekend!

The Global Change Observation Mission 1st-Water "SHIZUKU" was encapsulated by the payload fairing on May 4 (Fri) at the Tanegashima Space Center. The satellite is now in the very final preparation phase for launch scheduled next weekend.
At the SHIZUKU special site (at the Japanese site only), we publish photos of hand-made craft of the SHIZUKU made by many of you. We continue to accept support messages as well as your hand-made SHIZUKU craft. Please join us!
