Long March 4C launches Gaofen-3 Earth Observation Satellite
August 9, 2016 by Rui C. Barbosa
The long awaited launch of Gaofen-3 took place on Tuesday, lofted via the Chinese Long March-4C (Chang Zheng-4C) launch vehicle. The rocket, launched from the Taiyuan Satellite Launch Center’s LC9 Launch Complex at 22:55 UTC, successfully orbited the new addition to the Gaofen fleet of remote sensing satellites.
Chinese Launch:
Designed by CAST (China Academy of Space Technology), Gaofen-3 employs the CS-L3000B bus configured with multi-polarized C-band SAR at meter-level resolution.
The new satellite has a designed lifespan of eight years and will mainly be used by the State Oceanic Administration (SOA) of China.
Development of the new satellite was initiated in December 2010, with the engineering development beginning in September 2013. The satellite was completed in March 2016.
Gaofen (meaning “High Resolution”) is a series of civilian Earth observation satellites developed and launched for the state-sponsored program known as the China High-definition Earth Observation System (CHEOS).
In May 2010, China officially initiated the development of the CHEOS system, which is established as one of the major national science and technology projects.
The Earth Observation System and Data Center of China National Space Administration (EOSDC-CNSA) is responsible for organizing the construction of the CHEOS that is a near-real time, all-weather, global surveillance network consisting of satellite, stratosphere airships, and aerial observation platforms.
The Earth Observation System and Data Center, China National Space Administration was established in March 2010. The Center is principally responsible for organizing and implementing as well as managing CHEOS. It is also responsible for EO application services, commercial development, technology consultant and international cooperation.
By following an arrangement of integral observation from space, air and ground, the CHEOS develops a space-based system, near space system, aerial system, ground system and application system as a whole to materialize earth observation at high temporal, spatial and spectral resolution, which is now in smooth progress.
Overall, to meet the strategic demands of the national economic development and social progress. The initial plan presented five satellites.
Gaofen-1 uses a CAST2000 bus, configured with one 2 meter panchromatic, an 8 meter multi-spectral camera and one 16m multispectral medium-resolution and wide-view camera. The satellite realizes an integration of imaging capacity at medium and high spatial resolution and with large swath, with designed lifespan of over 5 years. It was launched on April 26, 2013.
Gaofen-2 employs the CS-L3000A bus, configured with one 1 meter panchromatic/4m multi-spectral camera, with designed lifespan of over 5 years. The satellite was launched on August 19, 2014.
Gaofen-4 was developed by CAST and is based on the new GEO remote-sensing satellite bus. It has orbital mass of 4,600 kg and was designed for a life span of 8 years. The satellite was placed into orbit by a Long March-3B launch vehicle from the Xichang Satellite Launch Centre on 29 December, 2015.
The future spacecraft, Gaofen-5, sports a SAST5000B bus and is configured with six types of payloads, including visible and short-wave infra hyper-spectral camera, spectral imager, greenhouse gas detector, atmospheric environment infrared detector at very high spectral resolution, differential absorption spectrometer for atmospheric trace gas, and multi-angle polarization detector.
It is designed for 8 years and is scheduled to launch in 2017.
On June 26, 2015, China launched the Gaofen-8 satellite. Developed by the China Aerospace Science and Technology Corporation (CASC), the satellite is part of a civilian program whose aim is to facilitate climate surveying, disaster response, precision agriculture mapping, urban planning and road network design.
Its imagery will be mostly used by the Ministry of Land and Resources, the Ministry of Environmental Protection, and the Ministry of Agriculture. The satellite was launched from the Taiyuan Satellite Launch Center using a Long March-4B rocket.
On September 14, 2015, another Gaofen satellite, Gaofen-9, was launched from the Jiuquan Satellite Launch Center, using a Long March-2D. Possibly a civilian version of the Yaogan Weixing-2 (Jianbing-6) satellite, Gaofen-9 will provide sub-meter class resolution optical images for city planning, road network design, land ownership determination etc. purposes.

So it turns out China's Yutu Moon rover could still be alive

China's Jade Rabbit rover was the first such mission to the Moon since the 1970s, and has contributed to scientific discoveries and top quality images of the Moon.
So when it was reported last week that the lunar rover had bitten the lunar dust, the news was understandably widely covered and received with sadness.
However, those reports may turn out to be premature.
News of the demise of Yutu, as it is named in Chinese, began on July 31 with the appearance of a widely-shared 'farewell' post from the rover's official account on Sina Weibo, China's Twitter-like social media platform.
It was then seemingly confirmed by Chinese state media such as People's Daily (Chinese) that Jade Rabbit had ceased operating at the start of its 33rd lunar night, some 972 days after launch on December 2, 2013.
The reports cited a source at the State Administration of Science, Technology and Industry for National Defense (SASTIND), which oversees the country's space activities.
This in turn resulted in a slew of articles in Western media reporting the death of Yutu, with the assumption that the rover had failed some time after the start of the latest lunar night, when temperatures sink as low as minus 180 degrees Celsius.

He would claim US has better satellite but can't back up his words. Everything from him is based on perception and not reality.Satellite spatial resolution of 15cm now and 1.5cm by 2020?
