“China-Europe” Mars Reconnaissance Orbiter Helps Scientists Understand Atmosphere near the Sun
Mars probe – Xinhua International Space Progress Report After the orbital mission to explore Mars “Tianwen 1” (Tianwen-1) of China with the ship Mars Express The European Space Agency’s (ESA) mission is helping scientists better understand what happened closer to the Sun during the near shutdown of 2021.
China’s orbiter encountered Mars opposite the Sun for the first time in late September. Until mid-October 2021 When communication with the earth is interrupted by solar radiation By this phenomenon, the Earth and Mars orbit opposite the Sun in almost a straight plane.

Reports indicate that Tianwen 1 and Mars Express sent out multiple signals during the event. This allows radio telescopes on Earth to examine the effects of those signals.
According to research published in the Astrophysical Journal Letters, solar flare events A strong solar mass ejection (CME) caused a disturbance that was observed lasting 10 minutes on Oct. 9, 2021, when Mars’ closest projection to the Sun was farther from The center of the Sun is 2.6 times the radius of the Sun.
In addition, a study led by scientists from the Chinese Academy of Sciences (CAS) revealed that atmospheric coronal waves were detected near the projection site, reflecting the process by which the magnetic field constricts the high-velocity solar wind. When the solar mass ejection ceases A high-speed solar wind was detected closer to the Sun than expected.
The Mars Sun Transit is a phenomenon in which Earth and Mars move to opposite sides of the sun, and the three are almost in a straight line. During the transit, Tianwen-1 and Mars Express (above) sent out frequent signals, allowing radio telescopes on Earth to examine how those signals were affected. Credit: ESA/Medialab
The Tianwen-1 orbiter, lander, and rover mission to Mars from the People’s Republic of China has successfully arrived at the Red Planet following an approximately 15 minute Mars Orbit Insertion burn that placed the craft into orbit. China’s Tianwen-1 Mars mission, comprising an orbiter, lander and rover, was launched on July 23, 2020. /nasaspaceflight/
