cctv news:on june 25 this year, chang'e-6 returned from the far side of the moon with samples, bringing back the world's first batch of lunar soil samples from the far side of the moon, totaling 1,935.3 grams.
these samples have been handed over by the national space administration to the national astronomical observatories of the chinese academy of sciences, the unit responsible for the ground application system of the lunar exploration project. later, these samples will be processed and provided to scientists for research. we also look forward to researchers bringing us more information about the moon and unveiling the mysterious veil of the moon.
chang'e 6: the moon landing design unveils the "veil" on the moon's far side
whenever you enjoy the moon during the mid-autumn festival, do you occasionally wonder what the far side of the moon looks like? this year, my country's chang'e 6 successfully reached the far side of the moon and brought back the first lunar samples. as one of the most technologically advanced lunar exploration missions in china's space history, how difficult is the chang'e 6 mission? let's listen to the designer's design for chang'e 6's journey to the moon.
at 14:07 on june 25, the chang'e-6 returner carrying humanity's first sample from the far side of the moon landed precisely in siziwang banner, inner mongolia, and the mission was a complete success.
chang'e-6 was originally a backup for chang'e-5, but unlike chang'e-5, chang'e-6 was designed to carry out a mission to the back of the moon, which put forward many new requirements for engineering design.
zhang wu of china aerospace science and technology corporation said: "this mission not only aims to return samples from the far side of the moon, but also needs to consider more backup products inherited from the original chang'e 5, making this mission, which was originally technically difficult, even more difficult."
zhang wu introduced that not only is the overall design difficult, but also the sampling on the far side of the moon requires adapting to the changes in the conditions on the far side of the moon. for example, the new landing area on the far side of the moon is more rugged, and the geological structure of the lunar soil is unclear, which also increases the difficulty of sampling. in addition, the far side of the moon cannot communicate directly, and a relay satellite is needed. therefore, the detector must adapt to the requirements of the relay satellite. the change in technical status is also a challenge, which requires full verification and preparation to adapt to the requirements of the entire system.
zhang wu said: "we considered a working design in case of relay communication failure. first, our drilling equipment was designed to complete drilling autonomously without relay communication, and then we made a multi-working condition design."
in addition, due to the different lighting conditions on the far side and the surface of the moon, chang'e-6 adopted an innovative retrograde orbit design for the first time on its way to the moon.
