China launched the Tianhui-1-03 Earth observation satellite at 7:10 UTC Monday on a Long March 2D rocket from the Jiuquan Satellite Launch Centre.

The Long March launch was China's 12th of 2015 and 215th overall, adding to China's growing constellations of Earth observation satellites.

Tianhui-1-03 will use stereo-topographic mapping techniques to provide data to be used for land resource surveying, environmental monitoring, land use, geological exploration and other applications.

The satellite's multi-spectrum camera has a ground resolution of 10 metres, forming images of 60 kilometres wide.

This third satellite in the series will operate in a 500 km circular orbit andis expected to raise the quality of images and positioning accuracy offered by the Tianhui satellites.

Tianhui-1-03 was, like the previous two Tianhui-1 satellites, developed by groups under the China Aerospace Science and Technology Corporation (CASC).

Officials note that the Tianhui series will contribute to an eventual all-weather, all-time, full-feature, multi-resolution space-based Earth observation network.

China's busy 2015
Monday's launch was China’s 12th in 2015, following missions involving four Beidou global positioning satellites, the Gaofen-8, Gaofen-9 and Yaogan Weixing-27 earth observation satellites, a classified ka-band communication test satellite, the Long March 6 debut, lofting 20 small satellites, and the maiden flight of the solid-fuelled Long March 11.

In October Jilin-1, China's first self-developed commercial remote sensing satellite, and APSTAR-9, developed and launched on behalf of a major regional satellite fleet operator, were launched.

Earlier in the year, the China Aerospace Science and Technology Corporation, the main contractor for China’s space activities, announced it would perform up to 20 separate launches in 2015, meaning a hectic final quarter of activity.

In December China will launch its DAMPE probe to hunt for dark matter.

The launch was the 215th of China’s Long March rocket families. The first took place in April 1970, when a Long March 1 rocket put China’s first satellite, Dong Fang Hong-1, into orbit.

2016 and beyond

China will make a return to human spaceflight with its first crewed space mission since 2013. Shenzhou-11 will liftoff from Jiuquan and will dock with China’s upcoming second space lab, Tiangong-2, which will be launched in advance of the taikonaut mission.

Next year will also see the new heavy-lift Long March 5 and medium-lift Long March 7 rockets make their debut launches. The two are designed to launch and service China’s future space station, as well as perform a lunar sample return mission in 2017.

In October Chinese state media revealed discussions on potential deep space exploration, including missions to Mars, Jupiter, asteroids, and, in the longer term, a crewed deep space mission.

The Netherlands and China intensify cooperation in space

26 October 2015

Today the Netherlands Space Office and the Chinese National Space Administration signed a Memorandum of Understanding in Beijing. The MoU was signed by NSO director Mr Ger Nieuwpoort and CNSA Administrator Mr Xu Dazhe in the presence of both heads of state King Willem-Alexander and President Xi.

With the MoU both space agencies intend to intensify existing cooperation and start new developments together with involvement of governmental organisations, scientific institutes as well as industry. Domains of cooperation are e.g. instrument development, earth observation services in the fields of climate, environment and water, as well as the exchange of space data.

China set to continue shooting for the stars
China Daily, October 28, 2015

It was midnight in mid-October, but Chen Min, who lives in a village near the Xichang Satellite Launch Center in Sichuan province, was still up and about. The vendor in her 20s was earning extra money by selling snacks to visitors who had arrived to watch a rocket launch.

"I make a living by farming, but whenever there is a space launch, I come here to make more money," she said.

Chen and a few other villagers started selling snacks part time six years ago. They said the opportunities have come more frequently recently. "I've seen so many rocket launches that I've lost count of the total number," she said.

The period of the 12th Five-Year Plan (2011-15) saw the highest number of missions in the history of China's space exploration programs, according to the China Aerospace Science and Technology Corp, the main contractor for the programs, which said 78 space missions have been carried out since 2011.

"The number (of launches) exceeded the total in the previous decade (2001-10)," said a corporation spokesperson, who preferred not to be named.

More than 97 percent of the missions have been successful, the highest rate among members of the world's elite space club, the spokesperson said.

Since 2011, those missions have sent 128 spacecraft from China and other countries into orbit, more than double the 60 launches between 2006 and 2010, according to the corporation.

"We have accomplished all the goals we set for the aerospace sector in the period 2011-15," the spokesperson said.

In the last five years, efforts have been made to lay the groundwork for the assembly of space stations and to facilitate lunar exploration.

In a major breakthrough, China experimented with space rendezvous and docking technology, which is crucial for the assembly of space stations. Within two years of the launch of China's first space lab, Tiangong 1, in 2011, three spacecraft-unmanned and manned-blasted off to test automatic and astronaut-controlled docking procedures with Tiangong 1. All the tests were completed successfully.

In 2013, the lunar exploration program completed a key step when the Chang'e 3 lunar probe was launched and soft-landed on the moon.

The country's launch-vehicle family is also expanding via the development of several new rockets, including the Long March 5, a heavy-thrust carrier rocket designed to launch space station modules and a future lunar probe that will collect lunar soil samples. Two new types of launch vehicle, the Long March 6 and the Long March 11, which can be prepared for liftoff at short notice, debuted last month.

"In September alone, five rockets, including the Long March 6 and the Long March 11, sent 27 satellites into orbit, which is a testament to the capabilities of China's space program," said Jiang Jie, chief designer of the Long March 3A series of rockets.

The next five years will also see the maiden flights of the Long March 5 and the Long March 7, which will carry unmanned cargo spacecraft into orbit.

The rapid strides made by the rocket industry during the 12th Five-Year Plan are the result of China's overall technological capability and government's support, Jiang said.

In the coming five years, the country will perform experiments in life-support technology, a critical factor for the planned space station. The China Academy of Space Technology has said the country's second space lab, called Tiangong 2, and a manned spacecraft will be launched next year, according to media reports.

China's first moon rover sets record for longest stay
Xinhua, October 29, 2015

China's first lunar rover, Yutu, has been operating on the moon for almost two years, setting the record for the longest stay by a rover, according to a Chinese lunar probe scientist.

Yutu was deployed and landed on the moon via China's Chang'e-3 lunar probe in 2013, staying longer than the Soviet Union's 1970 moon rover Lunokhod 1, which spent 11 months on the moon.

Its operations have streamed live through Sina Weibo, a Chinese microblogging site, and its Weibo account has nearly 600,000 followers.

Yutu experienced a mechanical control abnormality in 2014, but it was revived within a month and, though it is unable to move, it continues to collect data, send and receive signals, and record images and video.

"Human history is relatively short, and people are brimming over with curiosity about the universe," said Ye Peijian, chief scientist with China's Chang'e-3 program. "We have to explore more by going out."

The launch of Dongfanghong-1, China's first satellite, in 1970 made China the fifth country to launch a domestic satellite using a domestic rocket, following the Soviet Union, the United States, France and Japan.

China launched its manned space program in the 1990s and successfully sent Yang Liwei, the country's first astronaut, into orbit on the Shenzhou-5 spacecraft in 2003.

The Chang'e-1 mission in 2007 inaugurated an era of Chinese lunar exploration, followed by Chang'e-2 and Chang'e-3, with the latter marking completion of the second phase of China's lunar program, which includes orbiting, landing and returning to Earth.

Chang'e-3 delivered the rover and a stationary lander to the lunar surface in 2013, making China the third country after the Soviet Union and the United States to carry out such a mission.

Meanwhile, China is planning to be the first country to land a lunar probe on the far side of the moon, or "dark side of the moon," which is never visible to Earth.

The mission will be carried out by Chang'e-4, a backup probe for Chang'e-3, according to Ye.

Yutu, has set the record for being the longest working moon rover.

Yutu has been working for nearly two year now. Which is better then the last record holder, Lunokhod 1 (11 months long) of the Soviet Union. The US has never use an autonomous moon rover.

Yutu is China first ever attempt at an extra-terrestrial autonomous rover, which run into a problem of not being able to move after a while, so it is able to travel only a short distance. Hopefully China can learn from the problem, and improve in future rover mission.

Yutu is still working, so it could probably add more to the record,

From yutu, 'Mother earth, I miss you!' 5th of November 2015


Does Russian Lunokhod still take photo and send back signal after 1 and half year first landed on moon?

Excellent picture.

For comparison to Lunokhod 1, it doesn't make sense.
Lunokhod 1 worked perfectly as designed, while Yutu didn't.

During its 322 Earth days of operations, Lunokhod travelled 10,540 metres (6.55 miles) and returned more than 20,000 TV images and 206 high-resolution panoramas. In addition, it performed 25 lunar soil analyses with its RIFMA x-ray fluorescence spectrometer and used its penetrometer at 500 different locations.

I didn't say Lunokhod dont work as designed but isn't a fact Yutu still send back image and signal in a lifespan more than lunokhod?

okay, Lunokhod was born before the first mobile phone produced, and it worked as a horse while Yutu didn't spend much energy on what they want it to work.
Battery tech improved a lot.
That's all I can tell.

It's just like I emptied my fuel tank travel all over China and made as many contacts as I can, while you stayed still in Beijing with your full fuel tank on a broken car and take some pictures in Tiananmen Square.

After a half of a century, after many improvements, we could expect more on a unmanned rover.

So you shall not have expect Russia workhorse rocket like proton M explode in Mar 2015 since its introduction in 2001? But why it happen?

As for unmanned rover, let me remind all reader. For lunar rover mission, only 2 rover ever attempt in whole history. That is Lunokhod and Yutu. The rover needs to survive -165 degree Celsius condition which is much much harsh than condition on Mars. A unmanned rover has lesser chance of breakdown and failure on Mars than moon.

So Yutu is better than Opportunity too?
