The Ministry of Science and ICT and the Korea Aerospace Research Institute released the first Earth-Moon photograph taken by the lunar orbiter Danuri.
On August 26, Danuri photographed the Earth and the Moon together with a high-resolution camera about 1.24 million kilometers from Earth. This is taken for functional inspection at a distance more than 12,000 times the distance of the high-resolution camera for mission purposes.It also is very meaningful in that it is the first photo taken outside the Earth's gravity zone.
In addition, the magnetic field meter, another payload of Danuri, succeeded in observing the boundary of the Earth's magnetic field about five hours after the launch of Danuri.
As of Sep.1, Danuri has been traveling to the moon from a distance of 1.33 million kilometers (accumulated travel distance of 1.37 million kilometers) from Earth. In the future, Danuri plans to sail about 6 million kilometers to the moon's orbit by Dec.17 before entering the moon's mission orbit at the end of December through deceleration. After that, it will perform a science and technology mission by orbiting a circle 100km above the moon for a year from January 2023.
Meanwhile, the Korea Aerospace Research Institute will conduct a second trajectory correction maneuver for Danuri at 14:00 on September 2
The secondary trajectory correction maneuver is an essential process to minimize fuel consumption required for Danuri's Earth-Moon navigation and to reach the moon normally in time for the mission's schedule. The results of the second trajectory correction maneuver will be derived by the afternoon of September 4th through analysis.
Minister of Science and ICT Lee Jong-ho said, "Since the launch on August 5, we have been controlling Danuri 24 hours a day at the Korea Aerospace Exploration Agency control room. Through this opportunity, I would like to thank the researchers. The Ministry of Science and ICT and Research Institute will continue to do their best to succeed in Danuri's mission."
Meanwhile, Dr. Cho Young-ho, who is in charge ofDanuri's mission, said "Both the main body and the payload of Danuri are operating normally. The earth and the moon photos sent by Danuri this time are taken from a long distance, so the resolution is not good, but I am happy to show you meaningful results."
