All about China mars mission.
                     All about China’s Mars Mission
Introduction
• China launched a rover to Mars on July 23, suggesting a space race with the United 
States — NASA is scheduled to launch its own rover on July 30. 
• It also marks a busy week for Mars flights, with the UAE launching one on the 21st 
which does not require a landing, but an orbital flight which will research the Martian 
atmosphere.

Name and Timing
• This morning (July 23) at 12:41 a.m., the Tianwen-1 mission launched atop 
a Long March 5 rocket from the Wenchang Satellite Launch Center at 
Hainan Island. EDT (GMT 0441).

Brief History
• Tianwen-1 consists of an orbiter and a lander / rover pair, a mix of craft that had 
never launched towards the Red Planet together before. 
• Tianwen-1 's ambition is especially striking considering that it is China's first 
attempt on a full-on trip to Mars. In November 2011, the nation launched a Red 
Planet orbiter named Yinghuo-1, but the spacecraft flew back with Russia's Phobos-
Grunt mission and failed to launch it.

Expectation
• Tianwen-1 will arrive at the Red Planet in February 2021, if everything goes 
according to schedule. 
• Inside Utopia Planitia, a large plain in the northern hemisphere of the planet 
which also welcomed NASA's Viking 2 lander in 1976, the lander/rover pair would 
touch down on the Martian surface two to three months later.

Purposes or Applications
• This will be done with six different science instruments, described by the Nature 
Astronomy paper as Multispectral Camera, Terrain Camera, Mars-Rover 
Subsurface Exploration Radar, Mars Surface Composition Detector, Mars 
Magnetic Field Detector, and Mars Meteorology Monitor.

Orbiter
• The orbiter must finally move into a polar elliptical orbit that takes it as near as 
165 miles (265 kilometers) and as far as 7,456 miles (12,000 km) from the 
Martian surface.

Instruments Used
• The spacecraft will relay information from the rover home and collect science 
data on its own using seven science instruments: 
1. Two cameras
2. The Mars-Orbiting Subsurface Exploration Radar
3. The Mars Mineralogy Spectrometer
4. The Mars Magnetometer
5. The Mars Ion
6. The Mars Energetic Particle Analyzer

The Lander
• Apparently the lander does not do any practical science work, but acts as a rover 
delivery network. 
• By the way, that wheeled explorer tips the scales at some 530 lbs. (240 
kilograms), making it twice the weight of China's moon-exploring Yutu rover first.

Objectives of the Mission
1. Mapping morphology and geologic structure 
2. To investigate the characteristics of soil surfaces and the distribution of water-ice 
3. To analyze the composition of a surface material 
4. Measuring the ionosphere and the characteristics of Martian climate and surface 
environment 
5. Perceiving Mars' physical (electromagnetic, gravitational) and internal structure

Conclusion
• All three of these missions are planned for arrival at the Red Planet in February 
2021 by the UAE, China and the US. And when Mars' summer comes to an end, 
we will always have a winter on Red Planet to look forward to.
