The Mars Global Remote Sensing Orbiter, Lander and Small Rover[3] is a planned project by China to deploy a Mars orbiter, lander and rover on Mars. The mission is planned to be launched in July or August 2020[2][4] with a Long March 5 heavy lift rocket.[5][6][7]

Overview

China's Mars program started in 2009 in a partnership with Russia. However, the Russian spacecraft Fobos-Grunt carrying a Chinese orbiter Yinghuo-1 crashed on 15 January 2012, days after lift-off. After that, China started its own Mars project.[8]

The spacecraft is being developed by the China Aerospace Science and Technology Corporation (CASC), and managed by the National Space Science Centre (NSSC) in Beijing.[5] This Mars mission would be a demonstration of technology needed for a Mars sample return mission proposed for the 2030s.[5] The lander carrying the rover will use a parachute, retrorockets, and an airbag to achieve landing.[9]

The rover will be powered by solar panels, probe the ground with radar, perform chemical analyses on the soil, and look for biomolecules and biosignatures.[1]

The priorities of the mission include finding both current and previous life, and evaluating the planet's surface and environment. Solo and joint explorations of the Mars orbiter and rover will produce maps of the Martian surface topography, soil characteristics, material composition, water ice, atmosphere, ionosphere field, and other scientific data will be collected.[10]

Simulated landings have been performed for the mission preparations by the Beijing Institute of Space Mechanics and Electricity.[3]

Scientific instruments

The orbiter, lander and rover will carry in total 13 instruments, including: [5]

Orbiter
Rover
