Missions to Mars天问一号火星探测再传捷报导读:2月24日,中国首次火星探测任务天问一号再传喜讯。当日6时29分,天问一号探测器成功实施第三次近火制动,进入近火点280千米、远火点5.9万千米、周期两个火星日的火星停泊轨道。进入停泊轨道后,天问一号探测器将在此运行约3个月,环绕器7台载荷将全部开机,开始科学探测,并为择机着陆火星做好准备。
![]() Tianwen 1 enters the orbit of Mars for an ambitious mission. XINHUA After traveling more than seven months in space, Tianwen 1 is one step closer to Mars! Tianwen 1, China’s first Mars probe, successfully entered Mars orbit in February, according to the China National Space Administration (CNSA). It will stay in orbit for about three months before landing on the red planet. A small step on the red planet will be a big step for human beings. Humans have launched 46 Mars exploration missions since October 1960, but only 19 of them have been successful, according to China Daily. It’s China’s first spacecraft to Mars, and the missions are rather ambitious. Tianwen 1 aims to achieve “orbiting, landing, and roving” all in one journey, which will make the country the world’s first to accomplish all three goals with one probe, mission scientists said. Among the three tasks, touchdown on the red planet is the most difficult. The result mainly depends on the “breathtaking seven minutes,” which will deploy multiple cutting-edge technologies and accurate timing of each action, including the burning of engines and opening of parachutes to ensure a safe landing, according to the Global Times. The previous success of Chang’e 5 has accumulated experience in this regard which “boosts our confidence”, Wang Ya’nan, chief editor of Beijing-based Aerospace Knowledge magazine, told the Global Times. February was Mars month. NASA’s Perseverance Rover landed on Mars on Feb 19, and China’s Tianwen 1 and United Arab Emirates’ (UAE) Hope have arrived within orbit of the red planet. Although they started their Mars journeys at almost the same time, their missions vary. The Mars mission Hope Probe successfully entered the orbit of Mars on Feb 9, the Mohammed Bin Rashid Space Centre (MBRSC) announced. Perseverance landed in a deep crater near the planet’s equator called Jezero and will collect samples of rock and soil for further research, according to the BBC. Tianwen 1’s ultimate goal is to land a rover on Mars in May or June, and it will conduct scientific investigations on Mars’ soil, geological structure, environment, atmosphere and water, according to China Daily. “When we step into the far planets of the solar system, the magnitude of the resources and timeline required will take a global commitment,” US Congressman Frank Lucas said, highlighting the importance of international cooperation in space.
