Posted August 21, 2019

Technology introduced us to a whole new world, and it keeps on advancing more and more every single day. Who could have guessed we’d be living in an age with so much details and knowledge about the moon? Or even send people to study more about the moon and space? Well, it is now happening! Recently, there have been a lot of findings and photographs of the moon. China is one of the leading countries investing a lot of time and resources on studying more about the moon.

The Chinese Lunar Exploration Program

The Chinese Lunar Exploration Program conducts its research in phases which are aimed at completing various tasks. The phases are divided into six missions namely Chang’e 1, Changé 2, chang’e 3, Changé 4, chang’e 5 and chang’e 6 all of which had tasks assigned to them. The first task was to reach the lunar orbit which was completed in 2007 by chang’e 1 and in 2010 by chang’e 2. The second task was to land and rove on the moon as completed by chang’e 3 in 2013 and chang’e 4 in January 2019. Moving forward, the tasks of chang’e 5 and 6 which are to create an outpost near the South Pole are to be implemented.

Chinese Lunar Orbiter, Longjiang-2

The Chinese lunar orbiter, Longjang-2, also known as DSLWP-B was part of the chang’e 4 mission. May 2018 was when two orbiters of the change 4 mission were launched: Longjiang-1 and Longjiang-2.

When they were launched, Longjiang-1 failed to reach the lunar orbit, but Longjiang-2 was successful.  The relay satellite, Longjiang-2 was scheduled to have a lifespan of 1 year on the moon. It was 47kg (104-lb) and was set at a wavelength of 300-10 meters and a low frequency of 1-30 Megahertz. Additionally, for better observation and results of the mission, the lunar orbiter, longjiang-2 had an optical high definition camera which managed to capture over 30 high-quality pictures of the moon’s surface. The camera was developed by a Saudi Arabian company known as the King Abdulaziz City for Science and Technology.

Why Chinese Lunar Orbiter, Longjiang-2 was sent to the moon

With the set frequencies of 1-30 MegaHertz and wavelengths of 984-33 ft., the lunar orbiter, longjiang-2 was sent to observe the sky by performing radio astronomical observations of the moon’s surface as well as solar radiation.

Why Chinese Lunar Orbiter, Longjiang-2 was crashed

The Lunar Orbiter, Longjiang-2 crash on the moon was a planned occurrence after it had outlived its lifespan of one year. The China National Space Administration started planning as from January 2019. They planned to crash DSLWP-B with the aim of not leaving any debris in the lunar orbit. By lowering the low point of the lunar orbit of Longjiang-2 to about 500 kilometers, the satellite was forced to collide with the moon due to the orbital perturbations on July 31st, 2019.

China continues to put billions of dollars into space investment and also recently announced they successful launched the first commercial rocket that could be used to put satellite into orbit around the planet.
