China is About To Try a High-Stakes Landing on Mars

China is all set to attempt its first landing on another planet. After months in orbit around Mars, the Tianwen-1 spacecraft will deposit a rover called Zhurong on the surface of Mars. If successful, China will become the second country in history to explore the Martian surface with a rover. From a report: Tianwen-1 arrived at Mars on February 10, marking the arrival of China's first independent interplanetary mission. Since then, Tianwen-1 has been making close approaches to Mars every 49 hours as it flies in an elliptical orbit around the planet, each time taking high-resolution images of the landing site in Utopia Planitia, a vast plain that may once have been covered by an ancient Martian ocean. Chinese officials have said the landing attempt would take place in mid-to-late May, and a report on Twitter quoted Ye Peijian of the China Association for Science and Technology saying the landing will take place on May 14 at 7:11 p.m. ET. This aligns with estimates from amateur radio astronomers tracking the spacecraft. Mission scientists have been analyzing the topography and geology of Utopia Planitia to guide the spacecraft's landing attempt, and if they decide not to attempt a landing on May 14, they will have additional opportunities on May 16 and May 18. Named for an ancient Chinese fire god, the 529-pound Zhurong rover is similar in size to NASA's Spirit and Opportunity rovers, which landed on the red planet in 2004 and sent back exciting images and data about the planet's surface conditions. China's rover could make additional important discoveries concerning water and past habitability on the planet, paving the way for future human missions to Mars.Read more of this story at Slashdot.
