If successful, the Tianwen-1 will make China the first country to orbit, land and deploy a rover in its inaugural mission to Mars, further boosting China's space credentials after it last year became the first nation to bring back samples from the moon since the 1970s....
China's first Mars probe Tianwen-1 has successfully entered the orbit of the Red Planet on Wednesday after a crucial braking system was activated to decelerate the spacecraft's speed, enabling it to be captured by Mars gravity, according to China National Space Administration (CNSA). A...
"204 days and more than 480 million kms later, the#HopeProbeis now in the Capture Orbit of#Mars," the official Twitter account of the Hope Mars Mission tweeted shortly afterward, with the hashtag#ArabsToMars. The feat is monumental. Experts estimated the chance of successfully...
The aim of this chapter is to determine a preliminary orbit of Mars. The method of Herget is used and adapted slightly to obviate the need for a numerical differentiation. Lagrange's f and g functions are introduced. A method is borrowed from Escobal to calculate sector triangle ratios ...
解析 C 细节理解题。根据第四段中的“The country will then launch its first Mars probe in 2020, which is expected to orbit, land and put a rover on the Red Planet in 2021, after ten months of flying. ”可知, 2020年中国将发射第一颗火星探测器在火星上环绕轨道、着陆并放置探测器。故选C。
After 167 days flying in space, Mariner 9 reached Mars on Nov. 14, 1971. It fired its rocket for just over 15 minutes to put itself into orbit — a major accomplishment for NASA after the previous flyby missions. In space, though, things rarely go as planned. Mariner 9 was ready to...
The United Arab Emirates sent a spacecraft into orbit around Mars on Tuesday, marking a first for the Arab world and a major accomplishment for the country's young space program. The unmanned craft is now circling Mars to gather data on its atmosphere....
What that Mars probe will look like, how it will operate, and when it plans to actually launch are still unknown, but the country plans to have it operational by 2020. Only time will tell if China follows through on its plans, but if it does, it will be the first country t...
"Based on the current progress of other nations' Martian exploration projects, China is expected to become the first to complete a sample-return mission from Mars," he said, noting that the country has begun to set up the world's first Martian sample laboratory. ...
China's first fully homegrown Mars mission, Tianwen-1, arrived in orbit around the Red Planet today (Feb. 10).
