Streak of Moon Lander Crashes Prompts Questioning

As ispace works to determine root cause of fueling-related M1 crash, observers are left to ponder why landing on Moon has eluded all efforts in 21st Century, save for CNSA CLEP sequence Chang’E 3-5; SpaceIL Beresheet (2019) IMU failure led to ill-timed reset command, cutting main engine; ISRO Chandrayaan-2 (2019) suffered software error with similar result; JAXA OMOTENASHI (2022) semi-hard impactor lost comms with Goldstone Deep Space Station; Generally, low gravity / atmosphere and dust are challenging factors; Budget for testing / fuel margin may also contribute to lunar landing difficulty

China Moon Rover Prepares For 45th Lunar Day of Exploration as NASA Declares “New Race To Space”

Yutu-2 now in sleep mode, conserving electricity generated during day via PV panels while relying on RHU heating to survive 44th lunar night; In total Yutu-2 has traversed 1,239.88 m within Von Kármán crater on Moon farside South Pole–Aitken basin over 1,282 days of operations, while Yutu traveled 114 m; Despite prognostication from NASA Administrator Bill Nelson speaking to German newspaper Bild expressing concern over “China landing on the moon and saying: It’s ours now, and you’re staying out”, there are no signs of such an effort

Yutu-2 Moon Rover On Route to Investigate Unusual Rectangular Object within Von Karman Crater

The first mission to explore surface of the lunar far side, already traversing ~840m, soon reaching 3rd full year since landing 3 Jan 2019, has sighted a novel structure on 36th lunar day and is now in transit to it, ~80m distant from present location NW of Chang’e-4 lander, as reported by Andrew Jones via Our Space of China; While natural origin / geological formation is assumed, SETA advocates such as James Benford argue that lunar artifacts may be viable source of ET clues
