Footage of Chang'e-6's land on far side of the moon
- m_a_g 2y agoIs the footage fast-forwarded? I'd imagine landing to be much slower. Also, is that how the moon looks, or is this some kind of night vision?
- fernandopj 2y agoDefinitely. You can see the lander "breaking" to adjust fall trajectory twice, the actual burst wouldn't be that fast.

- beefnugs 2y agocamera footage taken in space is something weird indeed. I remember when i first saw how an eclipse affects shadows in real life. It immediately clicked in my brain why that early moon landing footage looked how it did. And also how easily so many people thought it was fake
- guerrilla 2y agoCan you elaborate?
- luyu_wu 2y agoShadows become incredibly sharp for instance, causing everything to look like it's rasterized in software!
- Toutouxc 2y agoIt looks exactly like on the first Apollo photographs. Guess they must’ve hired Kubrick's students. Jokes aside, there’s just one light source on the moon, and no atmosphere to provide diffuse light. The dynamic range (contrast) of the moon is something we don’t see often on Earth.
- qingcharles 2y agoAnd the lighting makes it really hard for the camera to see any stars, so the sky always looks deep black and fake which also adds to all those frustrating conspiracy theories.

- logtrees 2y agoAmazing work Chang'e-6 team, amazing work China! Congratulations!
- seatac76 2y agoGood stuff. Very consistent program to moon they have there.

- gcanyon 2y agoNice work, go team human! From https://en.wikipedia.org/wiki/Chang'e_6 https://en.wikipedia.org/wiki/Chang'e_6 "If the mission is successful, China will become the first nation to land, collect, and deliver samples back to Earth from the far side of the Moon."

- The_Colonel 2y agoYour second sentence (even of it's a citation) makes this about competition, kinda negating the message of your first sentence.
- mef 2y agocompetition within teams can be a good thing
- SoftTalker 2y agoI don't think anyone is really competing for this achievement right now. If I'm running a race with no other competitors, can I claim to have finished first? Or even to be racing?

- sinxccc 2y agoIn the past year there were 6 probes (include Chang'e-6) trying to make a soft landing on the moon and only half of them succeed or partially succeed. I'm not sure how it counts as "no other competitors".
- tromp 2y agoAt 0:28 you can see a brief glimpse of part of Chang'e-6 itself.
- pavel_lishin 2y agoI can't tell if that's part of the ship, or its shadow: https://i.imgur.com/NTiZuJe.png https://i.imgur.com/NTiZuJe.png
- ThinkBeat 2y agoIt is truly amazing how much engineering and science China has mastered. They have the newest space station as well. They appear to have made faster progress on production of more advanced computer chips as well but that requires some further investigation / proof. This all while a single hostile nation wants to dictate what China is allowed or not allowed to buy on the free market.
- tw04 2y agoIt’s also fueled by rampant IP theft. It’s a lot easier to advance when you’re not actually inventing anything.
- Dalewyn 2y agoBe that as it may, these things are won by whoever crosses the finish line first and China appears to be ahead of the west at this point and especially if current trends continue. Also worth noting that American space exploration achievements were also kickstarted by importing the talent from post-WW2 Germany.
- 6d6b73 2y ago"the talent from post-WW2 Germany" is that a new way of saying "Nazi war criminals" like von Braun?
- Dalewyn 2y agoThere aren't significant differences between a V-2, AIM-120 AMRAAM, Minuteman, Patriot, Tomahawk, Saturn V, Delta IV, Falcon 9, et al.. They are all metal pipes filled with boom powder that can be used to throw things up.
- 6d6b73 2y agoAnd a microchip is just a bunch of copper wires with sand around them
- jameshart 2y agoTranslations matter. There’s rather an important semantic distinction between claiming a ‘landing’ on the moon vs claiming ‘land’ on the moon. Currently the headline on HN reads “Footage of Chang'e-6's land on far side of the moon”
- Dalewyn 2y agoLooks like a bad translation, it's not even proper English. NHK reports[1] that China announced Chang'e-6 "landed" (着陸, chakuriku) successfully on the far side of the Moon.

- tectonic 2y agoSuper cool! We have been tracking this mission in Orbital Index for a while. https://orbitalindex.com/archive/2024-03-13-Issue-260/#chang-e-6-the-first-lunar-farside-sample-return https://orbitalindex.com/archive/2024-03-13-Issue-260/#chang... This mission required a communication satellite that loiters on the far side of the Moon as well to relay communications back to earth. https://orbitalindex.com/archive/2024-03-13-Issue-260/#queqiao-2 https://orbitalindex.com/archive/2024-03-13-Issue-260/#queqi...
- qingcharles 2y agoLove Orbital Index... just realized I stopped getting emails from you guys in 2022 :( Does it auto-unsubscribe if I don't open one for a while? I was away from the Internet for a few months.
- tectonic 2y agoGlad you’re a fan! It shouldn’t, unless it was 6+ months I think.
- MaximilianEmel 2y agoIt starts looking like a fractal halfway through.
- mmcconnell1618 2y agoYou can't really tell the scale of the craters because each time you get closer, more craters appear. I can imagine that even with stereoscopic eyes, a human could easily misjudge distance and scale too. We're not used to operating in such a barren environment.
- oefrha 2y agoThe video element didn't work for me on iOS Safari for some reason. Anyway here's the direct link to the video: https://www.sastind.gov.cn/video/0602ce6dl2.mp4 https://www.sastind.gov.cn/video/0602ce6dl2.mp4
- punk_ihaq 2y agoSo cool! At 0:28, you can briefly see the shadow of one of the landers legs about to touchdown
- uncertainquark 2y agoIf anyone’s interested, I did a deep dive into the Chang’e 6 mission, including clarifying some misconceptions: https://jatan.space/moon-monday-issue-174/ https://jatan.space/moon-monday-issue-174/
- oefrha 2y agoThanks, this is the most informative writeup I’ve read about the current and upcoming missions.
- uncertainquark 2y agoThank you! It’s part of the Chinese lunar special series I’ve been doing all month. Here’s the rest of the four: https://jatan.space/moon-monday-issue-175/ https://jatan.space/moon-monday-issue-175/ https://jatan.space/moon-monday-issue-176/ https://jatan.space/moon-monday-issue-176/ https://jatan.space/moon-monday-issue-177/ https://jatan.space/moon-monday-issue-177/
- ammo1662 2y agoThe "video" is not actually a video. It is composed by a series of images. So yes the video is fast-forwarded. And the probe will hover above the landing area and use a laser to detect the surface to choose the landing point. It can be seen in the video.
- mdrewry 2y agotrue, but aren't all videos just individual frames played in a sequential order?
- ammo1662 2y agoYes, you are correct. Sorry for misleading about that. I saw some comments that due to the limited bandwidth of the relay satellite, these images were taken every second. So it is actually not a "video".
- derjames 2y agotechnically, it is a "video" at 1fps
- nineteen999 2y agoExactly. A very under-cranked video.
- sangnoir 2y ago"Timelapse video" is the usual term for such videos.
- MaxPock 2y agoAnd then you remember the Wolf Amendment that was enacted to hold back Chinese space efforts and you laugh . According to this American law ,NASA is not supposed to be in contact with the Chinese government or Chinese government affiliated organizations.
- overstay8930 2y agoIt was just to delay missile development as Chinese affaires were caught gathering information for non-scientific endeavors, anyone with half of a brain knows that China was going to do this eventually.
- Simon_ORourke 2y agoGreat work, I'm curious as to how autonomous the landing was (I assume fully autonomous) - but since there's awesome video sent back from the dark side of the moon there must be some relay in orbit too. I'd give the Chinese space program more than a healthy 50/50 chance of landing humans on the moon again within the next ten years.
- ein0p 2y agoI consider this unlikely - it is at least an order of magnitude harder to land people there and get them back even if you already have the heavy rockets and experience required. The US remains the only country capable of repeating this feat within the next 10 years, in spite of the current timelines being ridiculously unrealistic, simply because it doesn’t have to guess quite as much and either already has or in the advanced stages of building the necessary technological base.
- binary132 2y agoI’m not convinced even the US is actually capable of that.
- ein0p 2y agoIt’s the only country that landed people on the moon like twice a year. Sure, that was 50 years ago, but some of those old timers are still around.
- JumpCrisscross 2y ago> not convinced even the US is actually capable of that Then you haven’t been paying attention to American aerospace over the past decade and a half. It is far more capable today than it was in the 60s, particularly in robotics. Where we lag is in human space flight, in part due to bureaucracy and complacence among the majors, in part because we have ridiculously-high safety standards.
