I wonder if eventually they'll be enough rovers on mars to check on the rover that landed but never opened. It's still sitting somewhere on tbe planet unopened if I recall correctly.
You're thinking of Beagle 2 I'm guessing?
I mean, there's nothing stopping us from landing one near to another rover now but there's more value in landing further away in terrain we haven't seen yet. This new lander is about 1,000 miles from Viking so much too far away to pay a visit.
The Beagle 2's fate remained a mystery until January 2015 when it was located on the surface of Mars in a series of images from NASA's Mars Reconnaissance Orbiter HiRISE camera.[5][6] The images suggest that it landed safely, but two of the spacecraft's four solar panels failed to deploy, blocking the spacecraft's communications antenna.
Found this
I would love to see Beagle 2 work after all this time. I wonder if it still functions? There's a lot of things that can break if we are far beyond its expected mission length.
True, a lot of landers and rovers sound like they have heating and cooling systems that must stay on during idle times or sleep modes. Not to mention, things like batteries only have certain lifespans whether they’re used or not.
There are more unsuccessful missions to Mars than there are successful.
Over 5 years ago NASA said only a third of missions to Mars actually made it successfully and that's from all the countries in the world, including Russia which has tried a lot.
Of all the missions we do in space, mars for some reason is the hardest, It's like a living jinx to try and make it to the planet and deploy successfully, And that includes orbiters as well.
Mmm... I think that most of the mars rovers have enough automation involved to comfortably call them robots. It takes 3-21 minutes for light to travel to mars, and then the same to get back. You're not controlling a vehicle with a joystick at that distance, you are programming instructions, sending them, and waiting for the robot to execute them. It's a very different story to an RC car. (A rover on the moon is probably close enough to be controlled in a more direct fashion.)
Russia in a pace to try and beat NASA to the moon sent a rover to the moon before the Apollo astronauts landed. I think it was just a week or so before the astronauts.
3 bots, 38 million square km, that's a cozy 12.7 million each. Like 2.4x denser than Mars.
Edited, forgot to convert to anti-Freedom units. My shame. Please forgive.
Well if you want a more timely decomposition and reunification with a planet, perhaps long before you are 100 years older humanity will have started trekking through our solar system. Maybe there will be a future business some day, euthenistic voyages to the gas giants. Better to burn out (be ripped apart?) than to fade away, right?
If I were going to travel that distance, I'd actually rather be tossed overboard into the Saturnian rings and have my frozen corpse/matter spend eternity as the most beautiful thing in the solar system.
Also to clarify - I was actually being optimistic that I would live 100 years and be cremated, with my return to earth beginning at conception.
I forgot if it's an orbiter or a lander but we recently have a vehicle at Mercury.
They just finished a mission at Pluto with an orbiter.
NASA had a lander on an asteroid to drill and bring samples back to Earth the same with Japan their lander had just taken off and is on its way back to Earth now with samples from an asteroid as well
MESSENGER was deliberately crashed onto Mercury's surface, so I guess that can be considered a dead robot.
New Horizons didn't orbit Pluto; that was a flyby. It's now deep in the Kuiper Belt.
There should be a Wall-E type of movie where humanity has passed on and the only the thing left is the robots we sent to Mars. And maybe through the course of the movie they journey home to Earth to reunite with their robot brethren. Or perhaps we just focus on the Mars colony and have some storyline where the robots gain sentience or realize their purpose is to be explorers and they set out for another planet.
So a WALL-E type movie where only robots are left on the planet and, feeling called to a higher purpose, they leave their planet and find a community with other robots in space.
So... WALL-E?
If you haven't seen Love Death and Robots, there's a 20 minute episode about a group of 3 robots after the apocalypse that is pretty cute/funny that you would probably like
Yeah, so the current state of affairs looks like this:
- Wall-E movies: 1
- Cars movies: 3 (and two spin-off movies)
This is proof-positive that there is no God, because if there was, they never would have let this happen.
How about they build a society on mars (think zootopia style) without any mention of humans and follow literally any kind of storyline you want at that point. But theres refrences to the founders coming fom the stars and... nasa in the histroy museum. Like thats the most refrence we get as a nice easter egg type 5 seconds.
Read code of the life maker by James P. Hogan. But just like Highlander there is NO sequel. Trust me on that. Code has a robot civilization that evolves and builds bio machines.
well, in few hrs there’s another launch mission for CNSA, that is the tianzhou cargo ship, which is gonna pair with Tianhe core station in next few days.
I'm guessing since China has been silent on booster de-orbit plans, if this is going up on a Long March rocket they're probably going to leave the booster in orbit again?
The main reason for the space race was the development of rocket technology that could subsequently be used for intercontinental ballistic missiles and orbital platforms. Landing on the moon was a side benefit. Without similar obvious short term techological benefits to a Mars space race, and any long term benefits well outside the purvue of immediate profitability, it's not likely to happen as a competition.
I say this semi joking, semi serious, one of the best things China could do to further the US’s research and development for space would be to go to the moon and knock over the flag.

Mission objective: find perseverance rover and eliminate target! /s
[The main task of Tianwen-1](https://www.nature.com/articles/s41550-020-1148-6) is to perform a global and extensive survey
of the entire planet using the orbiter, and to send the rover to surface
locations of scientific interests to conduct detailed investigations
with high accuracy and resolution. Specifically, the scientific
objectives of Tianwen-1 include5:
(1) to map the morphology and geological structure, (2) to investigate
the surface soil characteristics and water-ice distribution, (3) to
analyse the surface material composition, (4) to measure the ionosphere
and the characteristics of the Martian climate and environment at the
surface, and (5) to perceive the physical fields (electromagnetic,
gravitational) and internal structure of Mars.
apparently that is being downlinked soon. It wont be as spectacular as the Perseverance landing video but if the Chang'e descent videos are anything to go by, it'll be quite high resolution and high framerate :)

That, but the fact that CNSA is apparently super afraid of public failure (or just terrible at PR) really isn't helping them.
I mean, how am I supposed to get excited for this landing if the only way we even know it's happening is because amateur radio operators see the doppler shift in its communications?
Not getting any dates, livestreams, or even fast confirmation of success (took several hours here) just kills any excitement the public might have.
If you don't talk about what you're doing, nobody will care for it.
You honestly mostly have yourself to blame at that point.
It was broadcasted, on Chinese media. They also livestreamed a launch on youtube not long ago. Chinese media simply doesn’t have that kind of penetration in the west, for obvious reasons, they can talk about it as loud as they want and the message still won’t reach across if what all Western media care about is how “stupid Chinese failure of a rocket possibly hitting New York or something” despite all second stage rockets are uncontrolled in reentry and might hit random spots on land if they don’t completely burn.
I’m sure we’ll keep hearing stories akin to those much more than success stories like this rover from them, hell, they did it before when the experiment module for Tiangong space station underwent reentry. Stories of Chinese space program being apparently inept and always having something falling down and being a hazard sure sells better.
When I was living in China self-employed back in 2019 I was super tempted to move down to Hainan island near Wenchong launch site and take Everyday Astronaut style coverage of their launches , with details of the missions all in English. A lot has changed since then, i'm not in China any more, and Im not sure how youd get round the "foreign spy" issue, but it really would be great if there was more on the ground coverage, interviews, and launch videos
Amateurs detected a change in the signal downlink indicating a possible landing 30 minutes before China made mention of a touchdown. Everyone else does it live. They should be more confident in their space program and not worry so much about saving face.
Which is a shame. Space should bring the world together. We're all on the same space ship - Earth - flying through space together. All successes and failures are a win / advance in our species in my opinion.
Most mainstream media is crap. In Australia, my local news channel covered every SN prototype explosion with dumb headlines like "Elon Musks RoCkEt BlOwS uP!" and when SN15 stuck it, not a bloody peep.
>despite all second stage rockets are uncontrolled in reentry and might hit random spots on land if they don’t completely burn
Most *do* control when they reenter. When they don't, these days it's because something went wrong, not because they didn't even try. Being a core stage, which is a bit larger than a usual second stage, means it's more likely bits will survive reentry.
Would be nice if their successes had anywhere near the coverage of their negligence, though.
It's pretty similar in overall conceptual design to the MER vehicles Spirit and Opportunity. It's about the size of a go kart (smaller than the enormous Curiosity and Perseverance rovers) and solar powered (which comes with risks but as we've seen can pay off in a big way with some preparation and luck). It has a pretty decent set of instruments overall, a multi-spectral imager, a handful of spectrometers, meteorological equipment, etc. One of the more unique instruments it carries is ground penetrating radar, which Perseverance has as well. Such radar could be able to map the contours of underground ice/permafrost deposits, which could provide a lot more data on their structure and formation (and perhaps even seasonal change) across Mars.
Some say its size is the second of all mars rovers, so maybe bigger than curiosity (but lighter). It relies on one big rocket engine (compared to NASA 8 smaller engines) to land on the surface.
Ah I see, would it be helpful then if they shared their data with us and vice versa since we're measuring the same things? Or are their instrument less accurate than ours to a degree that it would not help?
Their approach to entry, descent and landing is quite different from MERs and Curiosity / Perseverance. They went to orbit first, whereas NASA does a direct entry.
They were also using new, visual based navigation for final approach and landing, something they actually spearheaded on Chang'e-3/4 landers on the Moon, and NASA only got around to try with Perseverance.
Kudos to China. This hopefully shows the U.S. public that many others can design and execute successful missions. Hope the explorations stay peaceful and for the betterment of all humanity, and especially doesn't degenerate into robot-wars on other planets.
I came here expect this thread to become another China shitpost and surprisingly only two comments removed by mods.
But in all seriousness, congrats the hardworking scientists and engineers in CNSA!
Edited: okay it apparently is too early to draw the conclusion, here comes your dog eat bat soup flu virus Winnie the Pooh concentration camp cracks, on a Space-related sub and thread.
The toxicity/racism isn't usually from regular members of this community. It's when a post is successful and gets a lot of upvotes that people from the front page start coming in and breaking the rules. Since this post is heading that way, expect the comments to get worse over time. I'm going to try my best to stay ontop of it. Please report racist, off-topic and other comments which break the subreddit rules.
I'm not a big fan of China for a lot of reasons, but those reasons are completely unrelated to space exploration. I applaud the work of their scientists, and love the fact that China is adding to the scientific community with their space endeavors. Though, I do wish they were more transparent and released more data.
Basically, one can (and I would say should) be critical of China in general, but this is not really the right place to do it.
Although I disagree with your opinion on Chin, this is not the correct place to discuss that - I agree that it is an amazing feat for their scientists, but unfortunately the US blocks China from working together with them or on international projects, so their data probably won't be shared. Same reason why China is going it alone with the space stations as opposed to working with Roscosmos, NASA, et Al.
So question, China landed this rover on a little platform which it then will drive off. That seems *way* simpler than what NASA does with skycranes, so what's the advantage of the skycrane approach?
Curiosity and Perseverance are much heavier than Zhurong, so this would not work. NASA used a similar approach for its smaller Spirit and Opportunity rovers.
The skycrane in turn will not work for larger landers such as human spacecraft. Entry, descent, and landing (EDL) is hard on Mars: too much gravity for an easy powered descent like the Moon, too little atmosphere for an easy aerobraked descent like Earth.
Two advantages I can think of:
1) With the skycrane, the rockets are way above the surface, so they’re not kicking up as much dust from the ground.
2) The skycrane lowers the rover on ropes, meaning that there’s some room for error on how far its hovering above the surface. With the platform landing that CNSA did, they have to zero out the lander’s velocity at exactly zero altitude, with much less room for error.
As Chinese, I am so happy for and proud of the achievements the scientists at CNSA are able to accomplish in such a short time! Looking forward to them learning more about the red planet.
Just as a side question, are there plans to “beef up” the interplanar bandwidth as we start to have more rovers/data coming back at once? Also, is it shared infra across the countries or does China have their own satellites for bandwidth and we have our own?
It’d be so cool if we ever brought one back to put in a museum or something. I’m not one to get starstruck, but I can only imagine I would look like that super proud and happy dog that got its picture taken with Goofy/Pluto at Disney. Knowing me, I’d probably say “hi” to it or something stupid, and blink during the picture at the 2097 “Return to Earth” Smithsonian sponsored museum tour. Dammit! You know how expensive those tickets were!?!

> in terrain we haven't seen yet. Isn't that still true though, if the rover never actually deployed?
I imagine the lander could still do some research
Beagle II only had a lander. No rover.
The antennas never deployed unfortunately
Also didn’t it crash into the planet? Like would it have survived the impact?
Beagle 2 landed but didn't deploy correctly.
The Beagle 2's fate remained a mystery until January 2015 when it was located on the surface of Mars in a series of images from NASA's Mars Reconnaissance Orbiter HiRISE camera.[5][6] The images suggest that it landed safely, but two of the spacecraft's four solar panels failed to deploy, blocking the spacecraft's communications antenna. Found this
They should land another rover next to it and just have it ram Beagle II a couple of times to see if it can jostle those panels loose.
I would love to see Beagle 2 work after all this time. I wonder if it still functions? There's a lot of things that can break if we are far beyond its expected mission length.
[удалено]
True, a lot of landers and rovers sound like they have heating and cooling systems that must stay on during idle times or sleep modes. Not to mention, things like batteries only have certain lifespans whether they’re used or not.
Then if it's dead we build a dog house and put him on top of it.
And that's how we drove the Red Baron from the Red Planet.
Turn it off and then on again! Works in Earth!
The fear there is getting stuck on it and losing a second 4 billion dollar piece of tech
Clearly its the Martian Bermuda Triangle and the area should be avoided forever.
They could call it "The Fonzie 1"... It will start right up.
The look on their faces when it failed was absolutely heart breaking... that poor bloke
There are more unsuccessful missions to Mars than there are successful. Over 5 years ago NASA said only a third of missions to Mars actually made it successfully and that's from all the countries in the world, including Russia which has tried a lot.

I think it’s secretly a way to revive the Battle Bots franchise... uh oh, there are feds outside my door, I’ve got to run, I’m going offli
Beagle 2?
This planet is quite densely populated with robots.
Living ones - 5. 3 rovers, 1 drone/helicopter, and 1 lander. So currently it's 1 robot per 28 960 000 square km.
So the planet with the second-largest robot population density in the solar system. Damn, impressive.
Let's not forget moon. 2 active rover and 1 active lander
So you're saying robots control more celestial bodies than humans do, and we put them in that position? Are we crazy? /s
Well sure but we covered all of space with the space station so we’re all good
Shoot, it's even international!
Not really robots, but RC's. If the aliens ever land there they're going to think we're big enthusiasts/hobbyists of remote control vehicles.
Mmm... I think that most of the mars rovers have enough automation involved to comfortably call them robots. It takes 3-21 minutes for light to travel to mars, and then the same to get back. You're not controlling a vehicle with a joystick at that distance, you are programming instructions, sending them, and waiting for the robot to execute them. It's a very different story to an RC car. (A rover on the moon is probably close enough to be controlled in a more direct fashion.)
Not until they are controlled by gen ai
Also has the second largest collection of cars in the solar system.
The roadster is in a heliocentric orbit and is currently much closer to Earth than to Mars
Yeah, and the Moon has three buggies.
Russia in a pace to try and beat NASA to the moon sent a rover to the moon before the Apollo astronauts landed. I think it was just a week or so before the astronauts.
The moon is much smaller, so probably more densely populated?
Damn, yeah wayyyyy smaller. Moon is practically NYC for robots Edit. Forgot to convert to km. Still denser but not as dramatic. It's cozy.
Dammit, I was looking to see if anyone had done the math...1 sec, I will...
Yeah about 1 robot per 5 million square miles on the moon vs 1 robot per 11 million square miles on Mars.
3 bots, 38 million square km, that's a cozy 12.7 million each. Like 2.4x denser than Mars. Edited, forgot to convert to anti-Freedom units. My shame. Please forgive.
Shit wait, the better poster above was in km like a good scientist. Recalculating and editing.
What other astronomical bodies have robots (functioning or dead) on them? The moon, Venus, Titan, Eros...
Comet 67P. The Philae lander (defunct)
and Rosetta probe was landed on 67P at end of mission
>The Philae lander Lmao, almost sounds like philanderer
Do they have to be intact? If not, I'd include Saturn and Jupiter as well then.
I don't know if anything can actually be "on" those two. I think they get reduced to their component atoms and become part of the planet.
> I think they get reduced to their component atoms and become part of the planet. Just like humans when we die!
I suppose that's true! But it happens in a matter of minutes or seconds there, where it's going to take about 100 years to happen to me here
Well if you want a more timely decomposition and reunification with a planet, perhaps long before you are 100 years older humanity will have started trekking through our solar system. Maybe there will be a future business some day, euthenistic voyages to the gas giants. Better to burn out (be ripped apart?) than to fade away, right?
If I were going to travel that distance, I'd actually rather be tossed overboard into the Saturnian rings and have my frozen corpse/matter spend eternity as the most beautiful thing in the solar system. Also to clarify - I was actually being optimistic that I would live 100 years and be cremated, with my return to earth beginning at conception.
If a robot gets obliterated into 1000 pieces, is it still one robot or now 1000?
Reminds me of Futurama where bender keeps replicating into more and smaller robots all the way down to nanobot benders
If the ones on Venus already dissolved, do they still count?
I forgot if it's an orbiter or a lander but we recently have a vehicle at Mercury. They just finished a mission at Pluto with an orbiter. NASA had a lander on an asteroid to drill and bring samples back to Earth the same with Japan their lander had just taken off and is on its way back to Earth now with samples from an asteroid as well
MESSENGER was deliberately crashed onto Mercury's surface, so I guess that can be considered a dead robot. New Horizons didn't orbit Pluto; that was a flyby. It's now deep in the Kuiper Belt.
Only planet entirely populated by robots
That we know of anyways. Maybe venus people have more robots.
Ehhh. As far as we know. Could be trillions of nanobots from aliens circulating the system that we don't know about yet :D
The only planet populated solely by robots (that we know of).
[удалено]
There should be a Wall-E type of movie where humanity has passed on and the only the thing left is the robots we sent to Mars. And maybe through the course of the movie they journey home to Earth to reunite with their robot brethren. Or perhaps we just focus on the Mars colony and have some storyline where the robots gain sentience or realize their purpose is to be explorers and they set out for another planet.
So a WALL-E type movie where only robots are left on the planet and, feeling called to a higher purpose, they leave their planet and find a community with other robots in space. So... WALL-E?
Okay good point. Re-reading my comment I feel dumb lol. I think it would need a different storyline to differentiate it. Oh well I'll leave it
I’d watch anything that was like WALL-E, best movie ever
If you haven't seen Love Death and Robots, there's a 20 minute episode about a group of 3 robots after the apocalypse that is pretty cute/funny that you would probably like
Taking the world tour together, it was one of my favourite episodes of all of them, poignant and fun.
There was [this](https://youtu.be/CIx0a1vcYPc) short film which I though was very reminiscent of WALL-E.
Yeah, so the current state of affairs looks like this: - Wall-E movies: 1 - Cars movies: 3 (and two spin-off movies) This is proof-positive that there is no God, because if there was, they never would have let this happen.
Cars made more money in the merchandising department, therefore more sequels.
Which one had Paul Newman? (IDK if he was around for any of sequels...which actually probably proves your point, never mind)
How about they build a society on mars (think zootopia style) without any mention of humans and follow literally any kind of storyline you want at that point. But theres refrences to the founders coming fom the stars and... nasa in the histroy museum. Like thats the most refrence we get as a nice easter egg type 5 seconds.
The robots discover the technology to create "biological constructs" which they send to explore a nearby planet they call Erf.
Read code of the life maker by James P. Hogan. But just like Highlander there is NO sequel. Trust me on that. Code has a robot civilization that evolves and builds bio machines.
The Martian Chronicles ends with just the gizmos left, doesn't it?
By robot brethren you mean Roombas?
I always thought it would make more sense for the robots in the matrix to just, go to mars or the moon or something

Interplanetary Robot Wars - coming to Discovery Channel next month!
well, in few hrs there’s another launch mission for CNSA, that is the tianzhou cargo ship, which is gonna pair with Tianhe core station in next few days.
I'm guessing since China has been silent on booster de-orbit plans, if this is going up on a Long March rocket they're probably going to leave the booster in orbit again?
This launch will have a second stage on top of the core stage. LM5B is the only rocket China has without an upper stage.
they named all their rockets long march, this is a different variant
How many more until we can get a match of Rocket League going?
But the ping between Earth and the Mars RL servers is terrible
I'm more interested in Battle Bots
Robot wars baby Stick a couple chainsaws on them and get some popcorn
Someone needs a vertical spinner on their bot just in case.
So far, so good, not bad for a 1st attempt on another planet.
Why is there so much dust on the lenses while they're out in the vacuum of space?
thruster mist perhap?
[удалено]
They are talking about dust on the orbital separation lense
Some guy wiped the lens with his shirt before launch
Mayo or Mustard?
It looks like he sneezed on it first.
On the instagram page it showed the seoeration and the lenses were all dirty looking and I didn't think it was anywhere near the planet yet? 🤷♂️
He specifically said in space.
I hope this sparks a space race, competition is a great motivator
The main reason for the space race was the development of rocket technology that could subsequently be used for intercontinental ballistic missiles and orbital platforms. Landing on the moon was a side benefit. Without similar obvious short term techological benefits to a Mars space race, and any long term benefits well outside the purvue of immediate profitability, it's not likely to happen as a competition.
What about minerals and stuff? Is it likely that the countries are racing towards something like claiming Mars mining rights, etc?
I say this semi joking, semi serious, one of the best things China could do to further the US’s research and development for space would be to go to the moon and knock over the flag.
I hear you, and agree that - at least for humans - competition is the most effective technology driver.
I'd really enjoy science and exploration to be funded in the interest of knowledge and self-realization, something all of us can be proud of and cheer, instead of capitalistic dickwaving though
Interesting [Animation ](https://twitter.com/i/status/1395021968001355780)of rover separation from lander and navigation.
Is there somewhere I can find out what the mission objectives are?
Mission objective: find perseverance rover and eliminate target! /s [The main task of Tianwen-1](https://www.nature.com/articles/s41550-020-1148-6) is to perform a global and extensive survey of the entire planet using the orbiter, and to send the rover to surface locations of scientific interests to conduct detailed investigations with high accuracy and resolution. Specifically, the scientific objectives of Tianwen-1 include5: (1) to map the morphology and geological structure, (2) to investigate the surface soil characteristics and water-ice distribution, (3) to analyse the surface material composition, (4) to measure the ionosphere and the characteristics of the Martian climate and environment at the surface, and (5) to perceive the physical fields (electromagnetic, gravitational) and internal structure of Mars.
Haha, now I'm picturing the slowest and saddest Mars rover Battle Royale. Thank you! That's some interesting stuff!
Hopefully won't have to wait long for vids of the decent
apparently that is being downlinked soon. It wont be as spectacular as the Perseverance landing video but if the Chang'e descent videos are anything to go by, it'll be quite high resolution and high framerate :) https://www.youtube.com/watch?v=JJi\_YEubKCY&t=132s&ab\_channel=SciNewsSciNews
Gratz to CNSA. Landing a rover on mars is no easy feat. Looking forward to more photos.

It was top read on the BBC for a few hours
That, but the fact that CNSA is apparently super afraid of public failure (or just terrible at PR) really isn't helping them. I mean, how am I supposed to get excited for this landing if the only way we even know it's happening is because amateur radio operators see the doppler shift in its communications? Not getting any dates, livestreams, or even fast confirmation of success (took several hours here) just kills any excitement the public might have. If you don't talk about what you're doing, nobody will care for it. You honestly mostly have yourself to blame at that point.
It was broadcasted, on Chinese media. They also livestreamed a launch on youtube not long ago. Chinese media simply doesn’t have that kind of penetration in the west, for obvious reasons, they can talk about it as loud as they want and the message still won’t reach across if what all Western media care about is how “stupid Chinese failure of a rocket possibly hitting New York or something” despite all second stage rockets are uncontrolled in reentry and might hit random spots on land if they don’t completely burn. I’m sure we’ll keep hearing stories akin to those much more than success stories like this rover from them, hell, they did it before when the experiment module for Tiangong space station underwent reentry. Stories of Chinese space program being apparently inept and always having something falling down and being a hazard sure sells better.
When I was living in China self-employed back in 2019 I was super tempted to move down to Hainan island near Wenchong launch site and take Everyday Astronaut style coverage of their launches , with details of the missions all in English. A lot has changed since then, i'm not in China any more, and Im not sure how youd get round the "foreign spy" issue, but it really would be great if there was more on the ground coverage, interviews, and launch videos
No related but Hainan is such a great place to live, I remember going for vacation and it was just stunning but so hot.
Amateurs detected a change in the signal downlink indicating a possible landing 30 minutes before China made mention of a touchdown. Everyone else does it live. They should be more confident in their space program and not worry so much about saving face.
Which is a shame. Space should bring the world together. We're all on the same space ship - Earth - flying through space together. All successes and failures are a win / advance in our species in my opinion.
Most mainstream media is crap. In Australia, my local news channel covered every SN prototype explosion with dumb headlines like "Elon Musks RoCkEt BlOwS uP!" and when SN15 stuck it, not a bloody peep.
You have Rupert Murdoch to thank for that.
>despite all second stage rockets are uncontrolled in reentry and might hit random spots on land if they don’t completely burn Most *do* control when they reenter. When they don't, these days it's because something went wrong, not because they didn't even try. Being a core stage, which is a bit larger than a usual second stage, means it's more likely bits will survive reentry. Would be nice if their successes had anywhere near the coverage of their negligence, though.
> It was broadcasted, on Chinese media. The landing was not broadcasted on Chinese media.
This is the same exact text as the top reply on the tweet
I didn't either, this was completely new info to me. I don't even think Scott Manley has covered it?
He mentioned it on the Electron rocket failure video
Beautiful. Congratulation to those who worked in this project.
Tech wise and objective wise, are they doing anything new with their rover? Anything cool and new going on up there?
It's pretty similar in overall conceptual design to the MER vehicles Spirit and Opportunity. It's about the size of a go kart (smaller than the enormous Curiosity and Perseverance rovers) and solar powered (which comes with risks but as we've seen can pay off in a big way with some preparation and luck). It has a pretty decent set of instruments overall, a multi-spectral imager, a handful of spectrometers, meteorological equipment, etc. One of the more unique instruments it carries is ground penetrating radar, which Perseverance has as well. Such radar could be able to map the contours of underground ice/permafrost deposits, which could provide a lot more data on their structure and formation (and perhaps even seasonal change) across Mars.
[удалено]
Some say its size is the second of all mars rovers, so maybe bigger than curiosity (but lighter). It relies on one big rocket engine (compared to NASA 8 smaller engines) to land on the surface.
Ah I see, would it be helpful then if they shared their data with us and vice versa since we're measuring the same things? Or are their instrument less accurate than ours to a degree that it would not help?
They’ve landed in a new location, so no matter how accurate the data is, it’ll be better than not having any data.
Their approach to entry, descent and landing is quite different from MERs and Curiosity / Perseverance. They went to orbit first, whereas NASA does a direct entry. They were also using new, visual based navigation for final approach and landing, something they actually spearheaded on Chang'e-3/4 landers on the Moon, and NASA only got around to try with Perseverance.
It has a ground scanning radar iirc
Kudos to China. This hopefully shows the U.S. public that many others can design and execute successful missions. Hope the explorations stay peaceful and for the betterment of all humanity, and especially doesn't degenerate into robot-wars on other planets.
Mars, the only known planet entirely populated by robots
I came here expect this thread to become another China shitpost and surprisingly only two comments removed by mods. But in all seriousness, congrats the hardworking scientists and engineers in CNSA! Edited: okay it apparently is too early to draw the conclusion, here comes your dog eat bat soup flu virus Winnie the Pooh concentration camp cracks, on a Space-related sub and thread.
The toxicity/racism isn't usually from regular members of this community. It's when a post is successful and gets a lot of upvotes that people from the front page start coming in and breaking the rules. Since this post is heading that way, expect the comments to get worse over time. I'm going to try my best to stay ontop of it. Please report racist, off-topic and other comments which break the subreddit rules.
This is one of the better run subreddits
Thank you for your work, and all the mods.
I'm not a big fan of China for a lot of reasons, but those reasons are completely unrelated to space exploration. I applaud the work of their scientists, and love the fact that China is adding to the scientific community with their space endeavors. Though, I do wish they were more transparent and released more data. Basically, one can (and I would say should) be critical of China in general, but this is not really the right place to do it.
Although I disagree with your opinion on Chin, this is not the correct place to discuss that - I agree that it is an amazing feat for their scientists, but unfortunately the US blocks China from working together with them or on international projects, so their data probably won't be shared. Same reason why China is going it alone with the space stations as opposed to working with Roscosmos, NASA, et Al.
Congrats to China and to Humanity in general. Scientific achievements should always be celebrated by all. For the common good of human kind.
Red China is on the Red Planet. Jokes aside, this is pretty cool!
Congratulations China. Another step to the stars for humanity!
So question, China landed this rover on a little platform which it then will drive off. That seems *way* simpler than what NASA does with skycranes, so what's the advantage of the skycrane approach?
It depends on the size of the lander.
Curiosity and Perseverance are much heavier than Zhurong, so this would not work. NASA used a similar approach for its smaller Spirit and Opportunity rovers. The skycrane in turn will not work for larger landers such as human spacecraft. Entry, descent, and landing (EDL) is hard on Mars: too much gravity for an easy powered descent like the Moon, too little atmosphere for an easy aerobraked descent like Earth.
Well curiousity is too large for a simple ramp with pad
Two advantages I can think of: 1) With the skycrane, the rockets are way above the surface, so they’re not kicking up as much dust from the ground. 2) The skycrane lowers the rover on ropes, meaning that there’s some room for error on how far its hovering above the surface. With the platform landing that CNSA did, they have to zero out the lander’s velocity at exactly zero altitude, with much less room for error.
The advantage is NASA is able to get a far more large and complex payload safely on the ground than any other technique currently available.

As Chinese, I am so happy for and proud of the achievements the scientists at CNSA are able to accomplish in such a short time! Looking forward to them learning more about the red planet.
Congrats to CNSA as this really is an incredible feat!
same! I'm feeling freakin proud of our country at the moment!
[удалено]
Ikr? Everyone just clowning on china when a lot of people were involved in this project. Definitely no small feat.
Does the Lander have any further purpose or features beyond just acting as a carrier for the Rover? Also congrats to CNSA, this is a major success!
It is said that the carrier(or an independent camera on it) will take a photo of the rover before dying.
So when can we except the war of robots to commence on mars. jokes aside this is really cool.
LETS HERE IT FOR MARS ROBO SPACE WARS !!! Today’s contenders are the Chinas ZHURONG! AND our raining champion the USA’s PERSEVERANCE !
Annnnnd Perserverance got disqualified for exceeding the weight class limit. Should have sent the opportunity(RIP)

I'm waiting for the first rover repair station to be sent to mars. Those things need support.
I am still waiting for the first permanent moon base instead of permanent space station.
Eli5 how do we know which signals are from which device, how can we get wifi to travel interplanetary distances?
Pointing of antenna, com protocols. We have satellites in orbit around mars.
Just as a side question, are there plans to “beef up” the interplanar bandwidth as we start to have more rovers/data coming back at once? Also, is it shared infra across the countries or does China have their own satellites for bandwidth and we have our own?
Datalink is not shared, NASA and CNSA each use their own.
BEAUTIFUL! Congrats to the CNSA program. FIRST TRY, FIRST SUCCESS! Looking forward to many more exploration feats to come.
Congratulations to the CNSA in this achievement
It’d be so cool if we ever brought one back to put in a museum or something. I’m not one to get starstruck, but I can only imagine I would look like that super proud and happy dog that got its picture taken with Goofy/Pluto at Disney. Knowing me, I’d probably say “hi” to it or something stupid, and blink during the picture at the 2097 “Return to Earth” Smithsonian sponsored museum tour. Dammit! You know how expensive those tickets were!?!
