The cooperative space mission between ESA and NASA has captured images of CME, which is an acronym for Coronary Mass Ejection.The main scientific mission only started in November this year
The instrument of the Solar Orbiter launched in February 2020 detected a pair of coronal mass ejections, the CME. The main scientific mission of the program only started in November this year, but it is already possible to receive the first batch of images captured during the flyover over the sun in February this year. Eruptions of particles from the sun’s atmosphere exploded in the solar system and have now been imaged, possibly triggering space weather on Earth.
The rig is in the cruise phase until the main mission starts in November. At the same time, during a specific verification and activity window, the ship’s instruments have been connected and collected scientific data about the space environment in its vicinity. On February 10 this year, the spacecraft was only half the distance from the earth and the sun, and provided the opportunity to conduct specific observations and verify the instrument configuration. At this stage, as seen from the earth, the spacecraft is placed “behind” the sun, which results in very low data transmission speed and it takes a long time to completely transmit data. The European Space Agency’s press release explained that it was a “happy coincidence” that caused the three remote sensing instruments of the Solar Orbiter to capture a pair of human-mass ejections throughout the day. In addition to the capture by the Ultraviolet Imager (EUI), Heliospheric Imager (SoloHI) and Coronary Artery, ESA’s Proba-2 and SOHO (ESA/NASA) and NASA’s STEREO-A also captured evidence of these phenomena.
SoloHI has now made its debut in these tests, and Metis has done it on January 17, and EUI has done it in November last year.Many musical instruments In situ Particle activity was detected around CME in February 2021. Data to be analyzed and conclusions to be provided later.
Understanding CME is considered essential to the scientific community, and the scientific community hopes to track the progress of its propagation in the solar system. The plane will return observation data very close to the sun, which has not been possible until now, and will return from high solar latitudes, providing the first image of the star’s unmapped polar regions. In addition to measuring the solar wind and magnetic field, the mission also aims to provide new insights to understand how the parent star works during the 11-year solar cycle and help better predict the cycle of stormy weather.
