Tianwen-1 Mars probe enters final mission of global remote sensing
China’s first interplanetary probe mission has come to its final stage of global remote-sensing exploration of the Red Planet after the Tianwen-1 orbiter successfully completed its fifth brake and entered a new mission orbit automatically late Monday, according to project insiders on Tuesday.
Four 102N engines worked for 260 seconds, reaching a speed increment of 78 meters per second for the late Monday maneuver of the Tianwen-1 orbiter, Global Times learned from the orbiter development team with the Shanghai Academy of Spaceflight Technology of the state-owned China Aerospace Science and Technology Corporation (CASC).
The Tianwen-1 probe has so far completed all preset mission stages including being captured by Mars’ gravity, the orbiter-lander separation, the landing of the Zhurong rover, and the roving and exploration of the rover. It has come to the final stage of global remote sensing, the academy said in a statement it provided to the Global Times.
