China launched the CBERS-4 satellite, jointly developed with Brazil, on Sunday, 2014-12-07 from the Taiyuan base by Long March-4B rocket, the 200th flight for the Long March rocket family.

INPE exhibits first CBERS-4 images

The first images of the Brazilian MUX multispectral camera aboard the satellite CBERS-4, were obtained on Monday (8) by the technicians of the National Institute for Space Research (INPE). The images were taken on the Buzios region (RJ).
MUX is the first camera to satellite entirely developed and produced in Brazil. 20 meter resolution multispectral and, records images in blue, green, red and infrared, in different groups, for use in different applications, especially in the control of water and forest resources.

First space-based 3D printing machine

SHANGHAI, Scientists have produced a 3D printing machine, the first of its kind in China, which astronauts will be able to use while on space missions, according to the China Aerospace Science and Technology Corporation (CASTC) on Monday.

The machine is capable of printing optical lens brackets used in spaceborne equipment, complicated components used in nuclear power testing equipment, impellers used in aircraft research and special-shaped gears used in automobile engines, said Wang Lianfeng, a senior engineer with CASTC Shanghai's research arm.

The machine, which uses both long-wave fiber and short-wave carbon dioxide lasers, can produce items smaller than 250 millimeters.

The machine, which looks like a gray cabinet, can fashion items out of stainless steel, titanium alloy and nickel-based superalloy.

"The products made will have to be tested thoroughly, due to the strict quality requirements of aerospace products," said Wang, adding that the prospect for 3D printing is promising.

Additive manufacturing, which 3D printing is also known as, is the processes in which three-dimensional objects are made through the layering of material. It is advancing rapidly and is increasingly used for industrial purposes.

Countdown to China’s new space programs begins

China hopes to put a rover on Mars around 2020, complete a manned space station around 2022 and test a heavy carrier rocket around 2030, a top space scientist revealed Sunday.
Lei Fanpei, chairman of the China Aerospace Science and Technology Corporation (CASC), the main contractor for the space program, revealed the details in an interview with Xinhua after the launch of CBERS-4, a satellite jointly developed with Brazil, from the Taiyuan base, by a Long March-4B rocket.
It was the 200th flight of the Long March variants since April 1970 when a Long March-1 carried China’s first satellite, Dongfanghong-1, into space.
Mars probe 2020
A feasibility study on the country’s first Mars mission is completed and the goal is now to send an orbiter and rover to Mars.
There has been no official announcement about a Mars probe yet, but Lei expects a Long March-5 carrier, still at the development stage, to take the orbiter into a Martian orbit around 2020 from a new launch site on south China’s island province of Hainan.
China’s space scientists have had their eyes on the Red Planet as their next destination since the successful soft landing on the moon late last year.
Last month, an actual-size model of a possible Mars rover was on display at Airshow China 2014, the first glimpse of how the vehicle might turn out.
China made an unsuccessful attempt to reach Mars in 2011 aboard a Russian rocket, but failed to complete the mission because of an accident during orbital transfer.
Space station 2022
China’s manned space station program is progressing steadily. Various modules, vehicles and ground facilities are nearing readiness.
Development and manufacture of major space products are at key stages, including the second space lab Tiangong-2, the Tianzhou-1 cargo ship, Long March-7 rockets and Shenzhou-11 spacecraft. The core module and two space labs will be tested soon, Lei said.
A new launch center in Hainan, the fourth after Taiyuan, Jiuquan and Xichang, is almost complete and can already launch some spacecraft.
The Tiangong-2 space lab will be launched around 2016 along with the Shenzhou-11 spacecraft and Tianzhou-1 cargo ship. Around 2018, a core experimental module for the station will be put in place.
By around 2022, China’s first orbiting space station should be completed. It will consist of three parts — a core module attached to two labs, each weighing about 20 tonnes.
Tiangong-1 was launched in September 2011. In June 2012, the Shenzhou-9 executed the first manual space docking with Tiangong-1, another essential step in building a space station.
Heavy rocket
A powerful carrier rocket is essential for a manned moon landing.
“We hope to make breakthroughs within four or five years on design and key technology for the heavy carrier, a solid foundation for developing such a rocket,” he said.
Breakthroughs are needed on the overall design of the rocket, including development of a 460 tonne thrust liquid oxygen and kerosene engine and a 220 tonne liquid hydrogen engine.
“We hope to finish all these within the next 15 years, so the heavy rocket will make its first maiden flight sometime around 2030,” Lei said
The rocket is envisaged as having a payload capacity of 130 tonnes to low Earth orbit. Once in service, it will help with missions between 2030 and 2050, and secure China’s position in terms of space exploration and technology.

Orion EFT-1 on Delta IV Heavy Rocket Launched on First Step to Mars

A Delta IV Heavy rocket thundered into orbit from Space Launch Complex 37B carrying the very first Orion Spacecraft into orbit.
This mission, labelled Exploration Flight Test 1 (EFT-1) is unmanned and will test Orion's onboard systems and heat shield for a re-entry from lunar missions. Lift-off occurred at 12:05 UTC, December 5th 2014, Orion will separate from the second stage at around 3 hours into flight before re-entering Earth's atmosphere and splashing down in the Pacific Ocean.
