4. Landing on Mars (登陆火星) Engineers use pi to help estimate the amount of uncertainty in the position where a Mars lander or rover will touch down. Many aspects of landing on Mars are uncertain: winds, air density, the initial speed and position of the spacecraft when approaching Mars...

Altogether, the landing took just under seven minutes to complete, prompting the nickname “seven minutes of terror.” During the plunge, two tiny spacecraft above Mars gathered data of the entire event. The pair of probes are known as the MarCO satellites, and they actually launched in May...

“Touchdown confirmed,” Swati Mohan, a member of NASA’s Entry, Descent, and Landing team, said. “Perseverance is safely on the surface of Mars ready to begin seeking the signs of past life.” The landing team of roughly 30 engineers at NASA’s Jet Propulsion Laboratory in California jum...

"At the beginning, the supra-regional topography of the landing site is shown from various perspectives within a radius of a few hundred kilometers," officials with the German Aerospace Center, known by its German acronym DLR, said in a statement Monday describing the video. [NASA's InSight ...
毅力号第一次选址研讨会关于工程指标的投票结果排序(最高分3分,最低分1分) | Mars 2020 Landing Site Workshop 在基本满足了安全着陆的工程需要之后,科学家们进一步逐一评估每个着陆点的科学意义:尽管火星如今是寒冷而干燥的生命荒漠,但曾经却有过温暖而湿润的环境,可能孕育过生命。如果火星生命真的曾经存在过,那或...
The rover will then start documenting its descent in great detail, snapping photos of the Martian surface and using radar to figure out its altitude. This NASA graphic shows the stages of the Mars rover Perseverance's landing. (Image credit: NASA/JPL-Caltech) Those photos will be employed ...
Early next week, NASA will attempt the grueling feat of landing a spacecraft on Mars, hoping to add to its growing collection of tech on the Red Planet's surface. This time, NASA hopes to place a robotic lander, called InSight, on a flat, boring part of the Martian terrain in order ...
