Beijing, May 16 It has been a year since China's Tianwen-1 probe landed on Mars. The mission has not only marked an important step in the country's interplanetary exploration but has also made a number of achievements in that time.The Tianwen-1 probe consists of an orbiter, a lander and a rover. On May 15, 2021, it touched down at its pre-selected landing area in Utopia Planitia, a vast Martian plain, marking the first time that China has landed a probe on the planet.A week later on May 22, 2021, the Mars rover Zhurong, which resembles a butterfly, drove down from its landing platform to the Martian surface, Xinhua news agency reported.On June 11, the China National Space Administration released the first photographs taken by Zhurong, signifying a complete success in the country's first Mars exploration mission.Since landing, Zhurong has continued moving southward and transmitted data back to Earth. It has completed explorations of the Martian surface, passed through multiple complex terrains, and detected Martian rocks, sand dunes and impact craters, obtaining a large amount of data using its onboard scientific equipment.From late September to October 2021, the Mars orbiter and Zhurong suspended their explorations and relied on their own autonomous systems to survive their first solar outage, during which time solar electromagnetic radiation increased and disrupted communication between the probe and Earth.In November 2021, Zhurong and the European Space Agency's Mars Express spacecraft performed an in-orbit relay communication test.In May 2022, using data gathered by Zhurong on the landing site, Chinese scientists found new evidence suggesting the presence of liquid water activity and hydrated minerals on the red planet.By May 5, 2022, the Tianwen-1 orbiter had been operating for 651 days at a distance of 240 million km from Earth.Zhurong had been working for 347 Martian days and travelled 1,921 metres. The orbiter and rover, operating normally, had obtained nearly 940 gigabytes of data.The Tianwen-1 mission is only the beginning of China's planetary exploration, and many new endeavours are in the pipeline.According to a white paper titled "China's Space Program: A 2021 Perspective", the country will continue its lunar exploration with the future Chang'e-6, Chang'e-7 and Chang'e-8 missions.It will complete the construction of an international lunar research station together with other countries, global organisations and partners.Future plans also include launching an asteroid probe, retrieving samples from near-Earth asteroids, and retrieving samples from Mars.The Tianwen-2 probe has entered the preliminary prototype development stage.Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
