images of the blue planet by the Danuri spacecraft


EARTH. The South Korean probe Danuri placed in orbit around the Moon transmitted its first images. Captured in late December 2022 by a high-resolution camera, its photos of our planet Earth are spectacular.

[Mis à jour le 11 janvier 2023 à 13h21] Launched on August 5, 2022 aboard a SpaceX Falcon 9 rocket, the Danuri probe is the first South Korean probe to fly to the Moon. After a journey of several months to reach its destination, the spacecraft is now in orbit around our natural satellite. Recently, it transmitted its first photos of Earth and the surface of the Moon. The Korea Aerospace Research Institute (KARI) posted the images on social media.

The Danuri mission has different objectives. It should, on the one hand, make it possible to test space technologies and, on the other hand, find a landing site for a robotic lunar mission that could take place by 2030. The probe is equipped with several cameras and instruments that will make it possible to study the lunar surface over the course of your mission. The Danuri spacecraft is expected to collect information on soil composition as well as the history of our natural satellite’s magnetic field. She is also carrying a NASA-supplied camera that should allow her to identify areas containing water ice at the star’s south pole.

The South Korean space agency published photos transmitted by the Danuri spacecraft. Captured between December 24, 2022 and December 1er In January 2023, these remarkable quality images were obtained using the high-resolution LUTI camera on board the spacecraft. This first photo was taken at an altitude of 344 kilometers above the Moon.

The second image was captured by the probe’s camera when it was just 124 kilometers above our natural satellite. As in the first photo, we can see the lunar surface marked by craters resulting from the collision with meteorites, as well as the Earth located in the background.

What images of Earth published by NASA?

Thanks to the various probes sent through space and the multiple satellites placed in orbit around the Earth, space agencies around the world offer pictures of the Earth. NASA recently released the first snapshot captured by GEOS-18, a weather satellite launched on March 1, 2022 to monitor weather conditions and hazards on the West Coast of the United States and Alaska.

The images provided by satellites allow scientists to study many phenomena such as forest fires, the movement of storms or even observe the evolution of glaciers threatened by climate change. So, on May 17, NASA’s Earth Observatory revealed an unprecedented image of the eruption of an underwater volcano located in the Pacific.

The International Space Station also produces unique images of our planet, like this image of Storm Sam over the Atlantic Ocean in September 2021:

It has been impossible for a long time to observe the Earth except through the photos published by NASA and by astronauts aboard the International Space Station (ISS). Today, the technologies available to us make it possible to obtain ever-increasingly high-quality images of our planet. Thus, the ISS offers a permanent live transmission thanks to the cameras placed on the station. It is thus possible to observe the Earth from the station, but also to locate the ISS in real time.

What are the characteristics of planet Earth?

earth is 3and Sun planet. Like its neighbors Venus and Mars, it is a telluric planet. It is therefore formed by rocks and has a solid surface on which we can move, unlike gaseous planets like Jupiter or Saturn. Seen from space, our planet has an intense blue color due to the large amount of water present on its surface.

Planet Earth is the largest terrestrial planet in the solar system ahead of Venus, Mars and Mercury. It is also the densest planet in the solar system. But what makes Earth special is that it’s the only planet known to harbor life. The emergence of life was possible thanks to a number of conditions such as the presence of liquid water, an atmosphere that maintains a habitable temperature, but also a magnetic field that protects the surface of the planet against electromagnetic radiation emitted by the Sun.

How big is the Earth?

Planet Earth has a diameter of 12,742 kilometers. In the solar system, only Mercury, Venus and Mars are smaller than our planet. Earth is 2.6 times larger than Mercury and 10 times smaller than Jupiter.

What is the Earth’s radius?

The Earth’s radius is measured from the center of the planet’s core to the Earth’s crust. Its length is 6371 kilometers. Its diameter is therefore twice as large: 12,742 kilometers.
