SIX rovers?
Apparently 6 payloads (instruments) on a rover?

That's correct (I have checked the original Chinese article). Also the 13 instruments refers to those on the orbiter.

Does anyone have a full list of them?

Apparently the article was amended - 7 instruments on the orbiter and 6 on the rover for a total of 13. ::)

This is good too see.  Having worked quite a bit with MOC and HiRISE images (with a few successful HiWISH request as well) it's good to see a larger field of view.  The narrow field of MOC and HiRISE can be frustrating.

The probe will be launched around July 23 ~ August 5 2020
After 6~7 months flying, the probe will captured by mars gravity around Jan or Feb 2021 (If everything went smoothly)

Scientific Objectives and Payloads of Chinese First Mars Exploration
http://www.cjss.ac.cn/EN/abstract/abstract2602.shtml
Quote
China plans to implement the first Mars exploration mission in 2020. It will conduct global and comprehensive exploration of Mars and high precision and fine resolution detection of key areas on Mars through orbiting, landing and roving. The scientific objectives include studying the Martian morphology and geological structure characteristics, studying the soil characteristics and the water-ice distribution on the Martian surface, studying the material composition on the Martian surface, studying the atmosphere ionosphere and surface climate and environmental characteristics of Mars, studying the physical field and internal structure of Mars and the Martian magnetic field characteristics. The mission equips 12 scientific payloads to achieve these scientific objectives. This paper mainly introduces the scientific objectives, exploration task, and scientific payloads.

China’s first Mars spacecraft undergoing integration for 2020 launch, dated May 29

Quote
“Mars 2020 mission spacecraft is undergoing integration,” Wang Chi, director of the National Space Science Center (NSSC) in Beijing, told SpaceNews in a rare update on the mission.
<snip>
The NSSC will be involved in integration of the instruments with the spacecraft.

The rest of the article appears to be confirmation of information already posted in this thread.

Quote
A successful launch of the Long March 5 will be required for China to be ready for the Mars Hohmann transfer window in [July-August] 2020, and missing this low-energy launch period would bring a wait of 26 months until the next mission launch opportunity.

Mars 2020, ExoMars 2020, and the UAE Mars orbiter should use the same launch window.

I am seeing comments on the launch thread that this spacecraft is named HX-1 which means "Mars 1" (original!).   Can someone please tell me what the "HX" stands for?

Likely HuoXing (火星), meaning Mars ('fire star').

Hou Xing, Fire star which is Mars.

for future reference on Chinese terminology, the first five planets are named after Chinese elements:

Mercury, Hui Xing, Water Star

Venus, Jing Xing, Metal Star

Mars, Hou Xing, Fire Star

Jupiter, Mu Xing, Wood Star

Saturn, Tu Xing, Earth Star


The rest of the planets are named after translations of their perspective Greek gods names.

Uranus, Tian Wang Xing, Heaven King Star

Neptune, Hai Wang Xing, Sea King Star

They are refered to as stars due to short hand, to proper, the full names are the following. Planets are fully named as Xing Xing, Wondering Star; star stars are fully named as Heng Xing, Eternal Star; moons except Earth's moon as well as Earth's artificial satellite are named as Wei Xing, Guardian Star.

I just wonder why they dropped the Yinghuo name (that of the failed Fobos-Grunt subsatellite)

My guess is the new project don't yet have an official name yet, as the Chinese name is still very generic. A naming competition probably will happen, Yinghuo-2 could be still be in the running, however, it is a very modest, failed mission from quite a while ago, so there is no attachment to that name.

Any news about if this mission is still on track for 2020?

And the name of the rover still isn't release?

The bottom part looks more like a cruise stage than an orbiter.

It's an orbiter nevertheless: it will have medium-res and high-resolution cameras (up to 0.5-m resolution), a magnetometer, subsurface radar, and several particles and infrared spectrometers.

Do you have the original source of this slide/presentation?
