A popular vote has decided the top three names from a shortlist of ten as part of a contest to the name the rover belonging to China's ambitious Chang'e-4 lunar far side landing mission, which is set to launch in December.

The shortlist was created following a public call in August for submissions to solicit names for the pioneering Moon mission.

After voting closed on October 10, it appears the clear favourite was 'Brightness' (光明, guangming) with 124,108 votes (Chinese) and 39 percent of the vote.

Second was 'Wang Shu' (望舒, a lunar-related deity from folklore) with 78,156 votes and 25 percent, with 'Stroller' or 'Hiker' (行者, xingzhe, a name linked to Journey to the West) in third place with 48,863 and 16 percent of the votes.

The final choice will be decided by a committee in late October, according to earlier reports. A science seminar to be held in Beijing on October 24 and 25 could see the name ratified.

The contest was initiated to popularise the mission and China's space achievements. A similar competition was held in 2013 and gave the name Yutu (Jade Rabbit) to the Chang'e-3 rover.

Chang'e-4 background

Chang'e-4 is a repurposed backup to the Chang'e-3 mission and will, after launch in December, attempt the first ever landing on the far side of the Moon, which never faces the Earth.

The mission is made possible by a relay satellite, named Queqiao, which is in a halo orbit at a Lagrange point beyond the Moon to facilitate communications between ground stations and spacecraft on the far side of the Moon.

The reliability of the new rover has been improved based on lessons from Chang'e-3, which saw Yutu come to a permanent halt after 114 metres. Nevertheless, it continued to carry out its scientific tasks.

Launch and landing

A Long March 3B rocket will launch the Chang'e-4 spacecraft from the Xichang Satellite Launch Centre, which has hosted all five of China's lunar mission launches so far. Launch is rumoured to be set for December 8, with a landing around December 30 or 31.

The lander and rover will target a landing within the South Pole-Aitken Basin, a huge and scientifically significant impact crater on the far side of the Moon.

The Von Kármán crater is understood to contain the selected landing site, according to a paper published by Huang Jun et al in the American Geophysical Union’s Journal of Geophysical Research: Planets.

China's core space station module, Chang'e-4 spacecraft and new launchers unveiled at Zhuhai Airshow

Chinese space technology, including a full size model space station module, the Chang'e-4 lunar far side spacecraft and new launch vehicles, have been unveiled at the Zhuhai Airshow in southern China.

The full size model represents the first time the 'Tianhe' core module for the future Chinese Space Station has been on display to the public.

The 16.6m-long module consists of a 4.2m-diameter resources compartment, a 2.8m-diameter life support and control section, and the docking hub, which will facilitate connection with further modules and visiting Shenzhou-crewed spacecraft and Tianzhou cargo vessels.

Wang Xin, deputy director general of the Space Station System project, under the China Academy of Space Technology (CAST), told CCTV that the rear docking hatch would be used to dock with Tianzhou freight spacecraft, while the robotic arms on display are to be used for on-orbit assembly and other operations.

The Tianhe module will be the first of three 20-metric-tonne modules that will make up the Chinese Space Station (CSS), along with two experiment modules to be used for a range of science objectives.

Launch is scheduled for 2020, after a necessary successful test flight of the Long March 5B rocket being developed to launch the modules. This was delayed by the failure of the Long March 5 in July 2017, and a return-to-flight will be attempted in early 2019.

Chang'e-4 lunar spacecraft

The Zhuhai Airshow, which runs from November 6-11, also features exhibits containing model Long March launch vehicles and the spacecraft for the Chang'e-4 lunar mission, which in December will attempt the first ever landing on the far side of the Moon.

Models of the Chang'e-4 lander and rover, as well as the Queqiao relay satellite, were out on view.

Deep space missions before 2030

On the sidelines of the Zhuhai Airshow, Zhao Jian, deputy director of the Department of Systemic Engineering under the China National Space Administration (CNSA), reiterated China's plans to launch four deep space missions before 2030.

The 2020 orbiter and rover mission to Mars—China's first independent interplanetary mission— will be followed by a mission to explore asteroids and smaller bodies around 2022.

A second Mars visit is targeted for 2028, which will be an as yet unprecedented sample return mission from the Red Planet. A Jupiter orbiter mission, launching around 2030, was the final mission noted.

The video below first demonstrates the Chang'e-5 lunar sample return mission, which could launch in late 2019.

New launch vehicles

Zhuhai also offered the first look at China's heavy-lift carrier rocket Long March 9, which is still under development, with China aiming for a first flight in 2028.

"The Long March 9 rocket would have a core stage with a diameter of 10 metres, which would double the five-metre core stage of the Long March 5. Length of the Long March 9 has exceeded 100 metres, so it would be the largest carrier rocket of China, and possibly of the world, according to currently known planning," said Zhang Zhi, chief designer of the Long March 9 rocket with the China Aerospace Science and Technology Corporation (CASC).

China is also developing a medium-lift rocket, the Long March 8, to carry payloads of up to 4.5 tonnes into Sun-synchronous orbit (SSO) at an altitude of 517 km. It is expected to make its debut flight in 2020, featuring a new modular design and reusable technology.

Also on display is the microsatellite rocket Smart Dragon 1, also known as Lightning Dragon 1, which was developed by the commercial entity Chinarocket under CASC. it is expected to have a carrying capacity of 150 kilogrammes to SSO.
