I wish NASA wouldn't use clickbait headlines :/ "Curiosity rover discovers sulfur crystals in Martian rock" would be nice.
But it is breaking news. The rover drove over a rock and cracked it. Using the drill would have been boring.
I'm not really seeing what's so clickbait about the title? They discovered something very surprising in the area. The area has an incredible amount of sulfates but I don't think anyone actually expected to find elemental sulfur in a natural environment, i.e. native sulfur formations.
If anything the article actually understates how wild it is to not only find this but that many of the surrounding rocks also show the same.
This region is believed to have been formed predominantly by erosion from flows of water or landslides. Native sulfur really only comes from 3 things:
1. Geothermal environments (ex: volcanos)
2. Hydrothermal environments (ex: hotsprings, geysers, etc).
3. Reduction of sulfates into sulfides by bacteria under specific conditions that result in the production of elemental sulfur as a byproduct.
Given that none of these 3 were expected from this area, that leaves a pretty substantial question of how it got there, how it was produced, and if it wasn't produced locally, where it came from.
So again I'm not really sure if it was clickbait by any means.

You're not wrong, but the person you replied to was doing wordplay on breaking news (cracking a rock open) and boring (as in drilling).
Oh damn. That's what I get for browsing HN without caffeine.
It's clickbait in what I believe is the original sense -- the title could easily state what specific thing it is talking about (sulfur), but instead it uses a vaguer term ("a surprise") so that you have to click on it to learn what the story is.
Calling it "clickbait" here doesn't mean it's a worthless article. It just means that the title is vague in an obviously needless way.

The title very much sounds like clickbait even if the article didn't turn out to be.
That took me a moment, and I’m sure I won’t be the only one. Breaking news indeed. Well done.
That's why I have a chrome extension which sends hyperlinks for certain sites through a local llama3 instance, fetching the content of the link, asking if the link text is clickbait based on the content, and for an alternate objective headline, which the chrome extension then replaced the link text with.
I'll bite - What's the extension?
I wrote it myself, it is currently just running in developer mode in chrome. I have it rewrite hn, reddit, and non-headline CNN links.
This might be an excellent application of the language models included in the latest Chrome builds.
I hadn't heard about that, I will look into it! The main reason I haven't packaged the extension for distribution is because it relies on the user also having ollama and I'd want to ship something self contained.
I couldn't believe what happened next.
…after using "this one weird trick"
You won't believe what the Mysterons did next
Or even more boring to prevent people from clicking “There are sulfur crystals on Mars”
That doesn't sound unique or interesting. Sulfur? So what. Not clicking.
Surprise? Well, I was already pretty sure if it was water or life they'd have said so, but now I'm intrigued. I clicked and now I know why the find is actually pretty interesting after all.

If it was unexpected, add in “unexpected”.
Very, very few people are going to click on the headline you've suggested, and engagement with the public is pretty important for NASA. "Martian surprise" is something that will get people interested, if only to click the link to see the picture of sulfur crystals and then leave the page 5 seconds later. Other news sites will also run with that headline, spreading the engagement far more than just a NASA article.
Getting public engagement is a part of how they defend (and increase) their budget, so it makes sense that they would be more likely to use click-baity headlines. ¯\_(ツ)_/¯

They need the right type of public engagement. That hypothetical person who sees the picture of sulphur crystals then leaves 5 seconds later is unlikely to support NASA. If they have enough negative interactions, I would suggest that it would achieve the opposite.
There is also a difference between a clickbait headline and a headline that genuinely engages someone. Something like "Unexpected discovery of sulphur crystals provides hints about Martian past" provides vastly more useful information and will probably be more appealing to people who have at least some interest in science. (Or at least rock collecting!)
At least in my case, I decided to read the comments here before even considering a look at the article. Not only did the idea of a "surprise" leave me thoroughly disinterested, but I have been bitten by NASA's hyperbole often enough to be hesitant about pursuing a clickbait link. Which is sad, because planetary science is interesting and the article itself wasn't that bad for something directed towards a general audience.

Do most people consider click-bait headlines to be a negative interaction? Arguably they should, but I don't think it's the case.
I don't know about most people, but the number of news sources that use information rich headlines suggest that there is a significant number of people who react negatively to clickbait headlines. And I suspect that many of these news sources float clickbait headlines from time to time to test the response of their audience. (Such headlines certainly pop up periodically on most news sources. It is the motive that I am uncertain of.)
Personally, I find clickbait titles lends an air of tabloidness to a publication. I wouldn't be surprised if that is a common feeling. I will also actively avoid, clickbait titles even from trusted sources, simply because it would be detrimental in the long term. Granted, I suspect the active avoidance part is an unusual behaviour.

Headlines (at least in mass media) have always been a hook to get the reader interested. Back when you had competing newspapers for sale on a stand, people would glance at the headlines and maybe buy a paper if it looked interesting enough.
There is no doubt that the headline is an important hook. Yet there is a difference between a deliberately vague or misleading hook (which I would consider clickbait), and one that conveys what the article is about.
I don't like watering down the defition of clickbait to mean any headline that gets the reader to click on it. That sort of definition is mostly an excuse for bad behaviour (e.g. misleading the reader).

Gosh, I really hope our premier scientific entities don't have to rely on page visits (ignoring bounce rate) to measure their impact or get funding :/
They're a scientific organization that lives or dies on the whims of people who have to win elections. Outreach is survival, and reach is essential to that.
Thats exactly why clickbait makes no sense. Who is it targeting? The lay person? They have no say in NASA's budget. If NASA wants funding they have to look at who holds the reigns in congress and give them pork. Thats it. That's their mechanism. When they were extremely well funded around apollo it was because they had pork a la advancing ICBM and surveillance satellite technology. Not because they got billy to tune in between episodes of will rogers.
They live and die on the whims of the CIA and military industrial complex. They are a platform for delivering spy satellites that's allowed to do a bit of science as a treat.
The public, for the most part, stopped caring about NASA after the US stopped going to the moon. Most of the rest believe NASA is hiding aliens or controlling the weather or some such nonsense.

From The Planetary Society: "None of NASA's budget is used for national defense or intelligence gathering programs; it is a civilian agency responsible for the peaceful exploration of space"
Do you have evidence to the contrary you could share?

GP is hyperbolic but essentially correct. Generally, states will move as much as science and technology research that is not militarily sensitive to the public sphere - such as NASA. This is because many scientists won't work for the military directly [1], but will work on stuff that has both military and non-military applications. This science is then used by the military for their purposes.
Many people have also written quite a lot about how the race to the moon was primarily funded because it was a military domination competition. Once the USSR decisively lost, the US stopped doing that expensive science. A good overview of the geopolitics of space exploration and research is the book Dark Skies by Daniel Deudney [2].

I'm not saying it's a good thing, just that it's a reality NASA has to deal with. so yea... :/
I mean, number of citations is only a slightly better way to measure impact than number of page visits.
I just visited the Johnson Space Center, and boy, was there a lot of PR for SLS and Mars on exhibit. I shouldn't have felt weird about it given the artists' depictions of planetary probes and spacecraft concepts I grew up with, but I've read too much about the reality of the program to get into a Mars expedition in a decade.
Meanwhile the miracle that was the asteroid hunter probe got an easily-overlooked station with an actual sample it brought back from Bennu in an inadequate magnifying display case.

SLS and Mars are the charismatic megafauna of NASA programs.
Even more likely, the user won't click to the article.
But two days later she'll mention to either me or another space nut like me "Hey, what was that surprise that NASA found on Mars?". And the conversation that sparks will be engaging and interesting for her.

Hate the game not the player.
It's only a game if people play. Disliking both works fine.
Lol okay but if you don't play the game, you lose.
You dont have to win every game. I'm fine not winning a Darwin award.
NASA is almost constantly struggling for budget, they need every eyeball they can get
Shallow clickbait makes me less inclined to support the institution, not more.
At a minimum, there are tradeoffs involved.

Right and they need to get the general public interested in this stuff, not nerds on the nerdsite
I think clickbait gets clicks, but doesn't build favorable sentiment or interest. I think this is true for the general public as well.
To this end it might make sense for a company/website paid based on click through engagement, but you will notice that most of those institutions are generally despised by the public.
I don't think being annoyed by clickbait is unique to nerds or such a sophisticated concept that the General Public can't comprehend it.
It's not like when NASA comes up for Budget approval being known as the agency that creates shitty clickbait articles will help them. In fact, I think it is exactly the kind of brand that they wouldn't want to build

They don't get budget by clickbait. How do I even as a registered voter have anything to do with NASA at all? I don't vote on their budget. I've never been offered to vote on a funding package for them. I chose from maybe two candidates as my representative on various levels of government, and am beholden to whatever platform they come up with.
Believe it or not politicians come up with their platforms largely based on the interests and desires of their constituents.
If NASA gets more people reading and learning about space, maybe more people will think it's a priority. It's not exactly rocket science.

Maybe it will get more people thinking space is just about garbage clickbait, and a waste of time and money.
if clickbait didn't work, they wouldn't keep using it
How exactly do you think they model and validate the relationship between clickbait and budget allocation or public sentiment.
it's all about those clicks baby
They come up with their platforms based on donors and their advertisers. Advertisers set the narratives in public discourse that inform public opinion. Politicians know where their bread is buttered. If NASA wants more money they should consider doing more secret squirrel stuff like they’ve done in the past. Its why satellites were funded. Its why apollo was funded. Its why the shuttle was funded. Little academic exercises are only going to get so much money compared to how much is sloshing around in defense related spending. Unfortunately for them I’m sure much of this space defense money they might have gotten otherwise goes to space force and other agencies that weren’t around or operating in space in the 1960s.
Damn I just lost 'The Game'. Sorry everybody who is playing.
It's all about the game and how you play it.

The law allows people to be total jerks. Should we now hate the law instead of those people?
The law everywhere does prohibit a LOT of jerk behaviours and a lot of jurisdictions have jurisprudence (I live in a common law country where jurisprudence is enormous) that amount to ''don't be a jerk''.
You missed the point because in practice you can always be a jerk within the boundaries of the law, no matter the law.
Well the law shouldn’t be responsible for stopping someone from being a “total jerk”, but yes you should be upset at the law for not meeting your expectations
I was hoping for japanium.
when the majority of the population in America suffers from brain rot, it behooves Nasa to engage the public with clickbait. it's not like Nasa gets the best funding in the world from our government compared to military and all our other genocidal ventures.
I have a hunch this valley is hiding many more geological secrets. If you look at the map, Curiosity is finally arriving at the more interesting bits of Mt. Sharp.
https://science.nasa.gov/mission/msl-curiosity/location-map/
https://science.nasa.gov/mission/msl-curiosity/location-map/
so cool. First time I've seen that map
It struck me that I have no idea how curiosity is instructed to move
I suspect someone can't be sitting in front of a computer with a joystick, moving a foot, waiting for curiosity to move a foot, then move another foot...
My next thought is nasa creates a route based on the map and then provides route data to curiosity. But there's no GPS (again, I assume). So is it all dead-reckoning? NASA somehow calculates 'move 100 ft forward, turn left 80 degrees, move 10 ft forward", etc?
(I am also assuming NASA uses metric)
OR does curiosity make its own decisions somehow?
I gotta go google some stuff now

That would be a long time between joystick commands, seeing as Mars varies from four to twenty four minutes away at the speed of light. Double that for round-trip (video to Earth, command to Mars).
That's how the BigTrak was programmed. Didn't realize I'm qualified for that job. :-D

So, what did you find?
It's both - mixture of exact commands + dead reckoning, and some semi-autonomous navigation (go to this rock).

That's a pretty cool map. Someone should do a "street-view" version.
Had it already been 12 years?
The last time that I looked at a map of Curiosity's location it was somewhere around Darwin and I suppose Cooperstown hadn't been named yet. And the map was certainly not interactive.

I'll be interested to hear more about this.
> yellow crystals were revealed after NASA’s Curiosity happened to drive over a rock and crack it open on May 30. Using an instrument on the rover’s arm, scientists later determined these crystals are elemental sulfur — and it’s the first time this kind of sulfur has been found on the Red Planet
We’ve found more stuff on Mars by driving over it than I would’ve expected.
Definitely more than just orbiting it. Even with the rovers having such an extended mission, it's still just a small fraction of the surface.
Just wait until we're stepping on it. That's when the real discoveries that will be recorded in the textbooks will begin.
It's cool how some minerals are just lying out in the open on Mars. On Earth this would have been washed away or buried under the soil.
As I was reading the article just now it made me wonder: does Mars have a really diverse landscape -- that just happens to be all covered in layers of red dust?
I have no idea. But I'd always thought it looked so homogeneous from the photos. But maybe it's just that the dust covers everything?
I have no idea. But I'd always thought it looked so homogeneous from the photos. But maybe it's just that the dust covers everything?
It's worth considering that most of the diversity of environments on earth are really diversity of ecosystems. Strip away the trees and the grass and the topsoil and then Earth would look like a desert wasteland pretty much everywhere.
Also, water! The different colors of dirt (containing copper, iron etc) near here are all exposed by water erosion.
Also, some of the geology is due to biology, especially with respect to erosion. (And oxygen level, I guess.)
Without plants, mountains and valleys etc. would be shaped a little differently, as opposed to "exactly the same but without green on top."

I'm wondering what that channel would have looked like when there was water flowing in it.

Check out Mars Guy https://youtube.com/@marsguy?si=AFAci3mConZv1L5- Dr. Steve Ruff. Excellent videos from an expert, but one terrific thing is the use of common objects (like mars guy cutout) that gives you some better perspective on the images.
between this and the iron nuggets sitting out in the open on Mars,..No Mans Sky is more realistic than i thought.
This was my first thought too lol "I've mind a million of those yellow veins of sulfur in NMS"
I wonder if it also has negative implications for finding life there—one of many possible explanations is the lack of biological forces breaking down and heterogenizing the surface.
They could've gotten more mileage out of a headline like "Was an alien crystalline life form just discovered, or...!?"
Chemosynthesis often does produce pure sulfur as a byproduct but so do volcanoes. a priori I'd put the most likely scenario for Mars at chemosynthetic life with photosynthesis never evolving, but this press release doesn't really move the dial on that with the information so far.
When we figure out how this formed, I wonder if that will have any impact on the feasibility of sulfur based lifeforms?
I would rather know why water on mars evaporated and if there was life on mars when there was water on mars
For the first question, see https://www.reddit.com/r/askscience/comments/uyaogu/comment/....
Must have come from Io. Lots of sulfur volcanos there.
Found the Martian hellmouth. ;)
what's that perfect white circle in the bottom left
oh boo, it wasn't part of a soviet probe :( :D
So martians are into rock n roll huh? :o)
Tl,dr: not a furby
> “It shouldn’t be there.”
What hubris. “We didn’t expect it to be there,” or similar would be more appropriate. I really would like to see more uncertainty and humility from scientists that base their work on theory.
