Looks like Mount Gerda.

How well would a rover like Opportunity on Ceres work? You don't have a dusty atmosphere to worry about but it's nearly twice as far from the sun as Mars so solar power is less effective.
Landing shouldn't be too different from landing on the Moon.

ayy lmao

>>7342356
Putting a rover on Ceres would be difficult. The Delta V Budget needed to put something on Ceres is similar to the budget needed to put something on Mars, and aerobraking is not an option on Ceres.

>>7342455
It looks like the toughest part is the capture, hence why Dawn took forever with its ion engine.
Why have only the Russians tried to put a lander on the Martian moons?

could be a giant quartz crystal

more than once:

Phobos 1 didn't make is, Phobos 2 did and sent images until a large unknown object appeared after which it went silent. Phobos Grunt developed an early malfunction and didn't reach transfer orbit. No luck so far.

They didn't know that Phobos and Deimos are

This ceres thing has become pretty clear to me.

Some sort of water/ice/whatever in the core is under pressure and occasionally bursts out in very specific focus bursts.

The bright spots is where it punctured a geyser straight out into space.

That dome is where it must of hit some harder rock and is pushing up.

I guess the only question left is why it erupts in such focused beams although I guess volcanoes do that too, not really sure why.

Dawn took a long time to capture at Ceres because it's engine's thrust is measured in micronewtons of force, or about the weight of a sheet of paper, accelerating an object heavier than a truck. Therefore it had to approach slowly, and at full thrust capture slowly. If we just launched a probe that used chemical engines to Ceres to would arrive in a little over a year and capture during a 10 minute burn to slow down. The only reason Dawn used an Ion engine was so that it would have enough fuel to explore both Ceres and Vesta, since ion propulsion gives you more speed per unit of propellant mass than chemical rockets.

>>7343809
Even a small lander would require a lot of mass to be taken away from the main payload's budget. It would be better to simply launch each payload on their own vehicle during the transfer window, and pay the extra ~200 million for the second rocket.


Also I agree that we should do more exploring of Venus, perhaps with an orbiter and an atmospheric probe simultaneously. Both should have strong cloud penetrating radar equipped to get an updated look at the surface and sensors to monitor atmospheric composition to look for sings of volcanic activity going on.

Good thing they crashed the probe before a new one was in place.

Can someone tell me how the fuck they presmuably got through the van Allen belt in 1969?

>>7348232
By realizing that exposure to radiation isn't as humanity-frying dangerous as you imagine it to be for the durations involved on the missions.

>>7348232

>The Apollo missions marked the first event where humans traveled through the Van Allen belts, which was one of several radiation hazards known by mission planners.[29] The astronauts had low exposure in the Van Allen belts due to the short period of time spent flying through them.[30] The command module's inner structure was an aluminum "sandwich" consisting of a welded aluminium inner skin, a thermally bonded honeycomb core, and a thin aluminium "face sheet". The steel honeycomb core and outer face sheets were thermally bonded to the inner skin.

>In fact, the astronauts' overall exposure was dominated by solar particles once outside Earth's magnetic field. The total radiation received by the astronauts varied from mission to mission but was measured to be between 0.16 and 1.14 rads (1.6 and 11.4 mGy), much less than the standard of 5 rem (50 mSv) per year set by the United States Atomic Energy Commission for people who work with radioactivity.[29]

No, this is just UFO shilling rubbish, made up by one of the many sites that make money off this kind of shit.

It was a camera glitch that was only on one wavelength detector, whilst it was nowhere to be seen on the other colour detectors.

>>7348783
Pic related and the principles of reflection proves that it can't be ice. Unless NASA is trying to subtly tell us that optical physics doesn't apply to Ceres.

>implying they are flat sheets of ice and not more crystalline structures

>>7349506
Equal angle of reflection applies to any object with reflective properties. You may pull out some pseudo-scientific vague statement that:
>>Hurr! Vacume space magic could do it!
Yet you won't be able to cite a source for that, since It's also a constant in space.

It doesn't radically change based on shape or elevation and anyone who has seen the flash off of a car wind-shield or ice-cubes on a sunny day has seen this in action.
The area in question on Ceres rotates outside of the angle of reflection and just like any observer passing by a reflective object, it would produce a brief flash if it were a reflection off of ice or similar material, not a constant source of illumination with no variance in brightness.

>>7348186
The probe crashed because it was out of fuel to control it's orientation, which meant it's antenna drifted away from Earth and we could no longer contact the probe, and with no fuel it's orbit decayed and it burned up in the atmosphere above Venus. If they could have chosen to keep the probe orbiting and collecting data they would have.

>>7349576

ayy lmao

>>7349374
This is the only thing that made me interested in this. And not many else seem to notice or care. How dumb.
I considered it being a parabolic shape reflective material, but in that case the location of the lights would change. Which they don't.

What I think it is in reality, although I would like to think it's aliums. Is that nasa has been a little deceptive with their images. And that it isn't actually as bright as it looks.

>>7349682
Last I checked, you can see polar caps from space but they don't throw off brilliant light at an impossibly wide angle of reflection.

>>7349683
That, or there would be more scattering of light and it still wouldn't remain that bright as it moves with Ceres' rotation.

>>7349701
>Last I checked, you can see polar caps from space but they don't throw off brilliant light at an impossibly wide angle of reflection.

We don't know the exposure settings of the camera, but we do know that the reflectivity of Ceres' surface is extraordinarily low (~9%). Basically any shot of Ceres' terrain that can resolve landscape details is going to result in the bright spots over-saturating the shit out of the camera, and NASA hasn't obliged with up to date albedo figures for the bright regions. I haven't heard an estimate more recent than the 0.4 provided back in February.

>>7347712
Why does it a triangle?

Why is everything on Ceres so angular?

>>7349755
It still looks less like glare and more like a source of radiant light. You do bring up a relevant point though, why is NASA being so reluctant and evasive with Ceres data? Why are the images they've shared with us black-and-white and appear to have been manipulated? Look carefully at the areas inside the crater here:

>It still looks less like glare and more like a source of radiant light. You do bring up a relevant point though, why is NASA being so reluctant and evasive with Ceres data? Why are the images they've shared with us black-and-white and appear to have been manipulated?

They don't look manipulated to me, but they're often heavily compressed. The reason why? Probably because the camera wasn't paid for and isn't wholly operated by NASA. The Max Planck Institute for Solar System Physics in Germany paid for the Dawn framing camera out of pocket, and they're holding down a lot of the information for themselves so they can get first crack at writing scientific papers about the collected data.

If you have 3D goggles, they do something.

What sort of ice? Why is significant ice only in this one location? Why isn't it sublimating? Where is the vapour? Not a satisfactory answer for science.

>>7349910
I never claimed it was an answer. Anyone on here claiming to answer this in the name is science is retarded or autistic. Nothing we, as 4chan users, can say or do is anything beyond speculation or conjecture.

>>7349910
>What sort of ice?

Water ice, I guess.

>Why is significant ice only in this one location?

Good question. No idea!

>Why isn't it sublimating? Where is the vapour?

It could be, but it might not be an easy signal to extract at the current distance with the spacecraft's instruments.

>Not a satisfactory answer for science.

Science is the process of getting the answers; it doesn't just "have" them.

That said, I really want to know why the bright spots are as diffuse as they are.

>>7349677
It was out of fuel because they kept pushing it into the atmosphere. It wouldn't have run out that quickly.

>>7349782
it's a giant fucking rock chunk

>>7349866
What Venus needs is an aircraft. Something solar powered that flies atop of the clouds could last for years.

<span class="math">e^{\left|x\right|}[/spoiler]

>>7349887

For you?

While the apparent geometric symmetry and prominence of that mountain is interesting, let's be real, that's all it is. And there are some patches of ice nearby.

>>7350014

Except the atmosphere is also incredibly hot and corrosive.

>>7350069
Not the upper atmosphere.

>>7350075

And what meaningful observation could be made up in the opaque atmosphere that one couldn't do with an orbiter?

So, what do you think would happen if the bright spots turned out to be artificial?

>>7350081
You get a better resolution and you aren't limited to orbital movement. It might also be possible to make temporary dives below the cloud cover.

>>7350089
Fund it.

I think it's a comet that hit one spot and is now sticking out a bit. That's why there's a crater around it.

Seems about right to me.

>>7350149

Right so a comet hit hard enough to leave a crater but is still cool enough to leave ice like a big snowball.

>>7350149
The comets we know are extremely dark. Basically the objects in the solar system that reflect the least amount of light.

>>7349887
>>7350006
Yes, this, but it's because it has such low gravity. The bigger an object is, the closer to a perfect sphere it gets. Smaller objects are much more irregular because gravity doesn't smooth everything on the surface as quickly. Ceres gravity is 36 times weaker than Earth's, for example.

>>7350162
We sent Rosetta to comet 67p to check out this hypothesis. It's wrong. Comets are not snowballs.

>>7350168

I was being facetious, as only an idiot would actually believe that a comet impact would leave a nice crater and snow.

>>7350168
>Comets are not snowballs.
Yup, 67P turned out to be a black dry rock.
Next surprise cometary activity in the Pluto system?

>>7350168
>>7350233

How do we know there aren't just different types of comets?

>>7350235
>How do we know
We don't, only the last 5 or so visited comets are not dirty snowballs.

>>7350257
It should be noted that all of them are periodic comets, with the exception of 1/P (Halley's comet) they were Jupiter family comets.
Ceres itself may have a similar composition and just a rounder orbit around the sun.

Does ceres rotate?

Can't they wait for the bright spot to move towards the darker side and see if it's actually just a reflection or a light source?

>>7350233
They're hoping for cryovolcanism. Intense outgassing seems unlikely so far from the sun.

>>7350404

I wonder what the energy source could be? Why so localized? Ceres is a lot more interesting for it anyway, much more so than the other thing orbiting out there with it, whatever the fuck it was called again.

>>7350233
https://twitter.com/esa/status/613698596958040065

>>7350424
Radioactive decay or tidal heating as Pluto and Charon are tidally locked.

Exploring Vesta was useful for comparison even i it was just a big space rock with a giant dent in it.

>>7350383

Yes, Ceres rotates, and Dawn is circling around it anyway. It's just reflection, not a light source. If it were a light source everyone would be freaking out, not just /x/tards.

Yfw Dawn mission ends and all we get are white pixels

>>7350715
It's not going to end any time soon. Currently it's in the survey orbit, then comes the high altitude mapping orbit when further instruments like the spectrometer are used and stereo photos are taken and finally comes the low altitude mapping orbit in which the neutron and gamma ray detector comes into play.
It doesn't have enough ability to break the orbit yet again and they won't risk contiminating Ceres so it's destined to stay in orbit forever and the mission could at least observe a full rotation around the sun.

>>7342258

>aliens from outer space notice our efforts to map Ceres
>they decide to contact us
>just before they do this, they realize we are going ape shit and losing our shit because of a mountain and some reflections

I guess it's like when we first became gods to the indians when we showed them mirrors and they lost their shit. Or when a puppy sees it's reflection on a mirror and we laugh at it's stupidity.

I'm so ashamed of being human. If we ever got contact I'd try my best to pretend I'm some alien blending in.

You're right about how gravity works, but this doesn't account for how the terrain on Ceres got that way in the first place.

Also, "irregular" is a funny word to describe a landscape that is so non-fractal.

>>7349910
>ice only in this one location?
isn't there more than one bright spot?

>>7342258

even if its ayy lmaos, its pointless to think about them. Universe isn't teaming up with life, it's actually against life. The reason why we don't have ayy lmaos integrated in our modern society is because humans are animals, not even intelligent in a sense

>>7350972
I'm so glad I don't have to consider the possibility any further, it makes me feel anxious that there might be other people out there and everyone knows that the one people who seriously devote their time to the subject are undesirable unemployed autistic members of the tinfoil hat club cult.

>>7351117
Nah, can't be on to something, don't you know that science is based on consensus? Independent scientific research and other scientists who challenged orthodox views have never been vindicated or proven anything worth-while. Plus occam's razor proves that the possibility is too silly to be a hypothesis worthy of merit.

>>7351201
What do you think the scientific method is.

>>7351212
no one has shown that life is exclusive to this planet, but it is common to assume that it is

why is that?

>New pic just dropped

>>7351212
It doesn't matter what I think the scientific method is, the consensus of scientific institutions and mainstream opinions is correct because they've always been free and open with their data and defend their positions with superior logic. Despite how hard the tinfoil enthusiasts attempt to subvert logic with their drivelling pseudo-scientific twaddle and citation of non-existent and constantly falsified material. Come on /sci/ don't be like this, you're starting to remind me of some of the posters on /x/. You shouldn't even be wondering what the bright spots on Ceres are, NASA knows it has to be ice because the idea that it could be anything created by an intelligence is to incredulous and therefore outside of the realm of probability. Don't even get me started on the angle of reflection bs that was already posted in this thread.

>>7349694
maybe nasa wants people to think it's ayylmaos so they get more publicity

>>7351230
>You shouldn't even be wondering what the bright spots on Ceres are
Nigger plz. There's nothing wrong with speculating, although immediately jumping to the conclusion that ayy lmaos did it is of course retarded.

>>7351218
Are you daft? Common opinion is that life exists elsewhere, we just have never had contact with it due to the extreme distances involved.

>>7351218
Some people tend to value empirical thought when discussing what exists.

Furthermore, what we can imagine exists being dismissed as silly shouldn't come to a surprise, seeing as this is /sci/.

>>7351218
>why is that?
crown of creation syndrome
united states of mind

>>7351218
Nah. What's common is to assume that anything with a reasonable non-alien explanation is probably not aliens.

http://www.esa.int/Our_Activities/Space_Science/Rosetta/Exposed_water_ice_detected_on_comet_s_surface

>>7351242
Yes, the possibility that the lights on Ceres could be from an intelligent source is retarded. The problem is that speculation inevitably leads to the consideration that this could possibly be the case. This is why speculation on this point is something that should not be happening. We should be leaving the heavy thinking, figuring and analysis to NASA and other organizations with the funding and prestige to make accurate and sensible claims. Not opening up a new way for foil-lords to harp on their favorite explanation for anything anomalous. NASA shouldn't have even shared these low-quality images of Ceres in the first place precisely for that reason.

>>7351280
Your solution for, "some people act retarded with information," is, "deprived most everyone of the information"?

Do you know how important PR shit is these days?

>>7351218
What are you babbling about? Until life is found on another planet, this planet is the only planet we know about with life on it.

And I have news for Drake. fl is 0.

>>7351346
the assumption that life is exclusive to this planet comes directly from religion

>>7351352
>religions all have the same tenet that Earth is the only planet with life

>>7351359

your point?

>>7351363
None of the Abrahamic religions state anywhere that Earth is the only planet with life on it; only that god made earth and put man on it. They mention no other planets, but also do not restrict that possibility.

I'm an atheist, but you? You're a turbofedora. I bet you think everyone would be fine and happy and there'd be no wars if only all of us didn't believe in a god.

>>7351379
the bible teaches implicitly that the only things he created with intelligence are the angels, man, and the animals

furthermore, the bible clearly indicates that the fate of the universe (every other planet and star) is forever linked to God's timetable for mankind and the Earth
one day, Christ will return to Earth and complete the final act of man's redemption (2 Peter 3:9-10)
he will destroy this present universe and create a new heavens and Earth (2 Peter 3:7,10; Revelations 21:1)
all the stars and planets will be destroyed, along with the Earth

it's not hard to see how the assumption came into being

and i'm not even atheist, i'm just saying

Is it ayyyliums or not

>Why isn't it sublimating?

The probe has detected out gassing water vapor from Ceres.

>>7351555

That's to be expected, but why is the bright spot not sublimating?

In this Ceres image you see a relatively fresh impact, which left a crater with surrounding rays of ejecta. Notice how it doesn't look like someone threw a nice snowball at the surface, like the comet impact people here are suggesting. So stop it.

>>7351343
The only reason you think that way is because you don't realize how subversively dangerous alien conspiracy theorists are!

>>7350081
You can 'smell' the air and perform extremely accurate measurements, and you can get much better radar image resolution from close up.

Pretty nice shot. I posit that there's probably some interesting geology somewhere on a planet as large as Venus, but it'd be an expensive exercise to look at it.

The Ceres bright spots sure seem to be rustling some jimmies. One interesting measurement so far is the albedo, calculated to be 40% which is about that of snow, more reflective than ice.

>>7354228
40% albedo is about that of plaster, not snow.

Top retard. All you know about optics came from that one pic didn't it?

Here's another pic that might help you out.

From the internal saltwater ocean.

>>7354731
Not the guy you're replying to, but I'd like to note that this pic still obeys the law of equal reflection, but the normal line is not the same across the surface. This is DIFFUSE reflection, not specular reflection, which is what the other anon believes this phenomenon is

Who said the internal ocean is saltwater?

>>7354782
Seriously though there's obviously no proof of it being saltwater. But Ganymede is known to have an internal saltwater ocean and Ceres seems somewhat similar to the Galilean moons.

uh... /sci/ How do comets orbits work? why some of them have a XBOX HUEG orbit?

>>7354801
The theory is that they come from the fringes of the solar system called the Oort Cloud and are disturbed in a way that leads them to the inner solar system during which the heat up and gas out. As they continue they may end up reshaping their orbit so that it stays closer and closer to the sun.
Ultimately there's still a lot to explore, a possible target would be a centaur, small bodies that combine features we know of comets and asteroids.

>>7354837
How come other bigs rocks don't fall into the sun as fast like comets? is it because comets already have some momentum while the other rocks are falling more slowly?

>>7354853
They have a more circular orbit. If they got knocked out of that they may as well become comets.

>>7354857
If you remove a big planet from the solar system would another planet get slingshotted by this?

Is the satellite going to get closer and eventually be able to make a good enough photo for us too decide what the fuck that light source is?

why protect a lifeless husk from contamination by a satellite? i don't understand

>>7354911
Because they think there's a possibility for life and won't take any chances.
I'm not sure if a crash landing would be a good idea anyway.

I want to believe, anons. I want to believe.

>>7354911
>a lifeless husk
... in your ill-considered opinion

The latest image release isn't particularly exciting, but it does show an abundance of craters with central peaks, which implies a relatively elastic crust made largely of rock. Frozen bodies, due to the hardness of water ice, tend to have flat craters.

>>7354918
So.. with say mars they're already pretty sure they killed anything that might exist there? Since they're landing rovers like it's no thing.

I honestly don't see how Ceres could hold any life that would be endangered by a crashed satellite, what do they expect is gonna happen?
They're honestly considering they'll physically crash it into the last living bacteria on Ceres??
I mean I know Americans are very good at murdering things from high above but come on..

Looks more like this impact than the bright spots.
>>7351562

The bright spot is quite distinct and very prominent from a long way away.

>>7354732

There is no ocean it would be ice.

>>7354796

Ganymede has powerful tidal forces working on it and has a bright crust of ice, it is nothing like Ceres.

>>7351437
Photos still need light to be seen. By the time the picture of the dark side was exposed long enough, it would have rotated again.

Do tidal forces create salt? We'll see whether the internal water on Ceres is liquid or not but there's no reason why it can't be salty.

PURGE THE XENOS

THEY'RE MOCKING US WITH DICKS

>>7355999

Checked.

>>7355881
Water being in contact with rock causes salt to leech out into the water. Earth's oceans are salty because billions of years of water washing down through rivers and leeching different salts from rocks, mostly sodium chloride and potassium chloride. It is reasonable to assume that any other object with liquid water in contact with it's lithosphere will also build up salt in it's hydrosphere.

>>7356060

It's quite an assumption that Ceres has liquid water, considering how small it is and the lack of tidal and solar energy out there. The object's known density suggests icy composition is also indicative that there wouldn't be significant amounts of radioactive elements to provide energy.

So really, try and stay within the bounds of possibility.

>>7356060
Wouldn't in turn water stay liquid for a longer period the more salt it has dissolved?
Ceres could have an internal heat source as well.

>>7356064
If you know everything about Ceres then why did they have to send a probe?
Detecting a potential subsurface ocean is one of the aims in the mission. It's not fringe science like extraterrestrial intelligence in Ceres.

>>7356065

True, in fact if Ceres had a liquid internal ocean in contact with water for enough time that it could get salty, as the temperature dropped and the ocean began to freeze out, the remaining water would get so salty that it couldn't freeze any more. That's why we think Ceres may have an internal ocean loaded with salt.


>>7356064

I'm not assuming Ceres has liquid water, I'm saying that if it DOES have an internal ocean in contract with rock, it WILL be salty, because that's the consequence of those conditions. And if it did at one point have a large internal ocean, which would be salty, it may still have some remnant ultra-salty water buried deep under it's icy surface.

>>7356073

Why don't you apply some reasoning before spouting bullshit? You stupid cunt your cognitive dissonance is causing you to grasp any straw no matter how laughable. Why don't you fuck off back to high school and learn some shit dumbass.

>>7356097
Why are you so salty?

>>7355814
>moving the goalposts
If you made another reply earlier, it was to a different anon. These pictures are old, and they've been saying, for quite some time now, that the bright spots are not a light emitting feature, but a reflective one. It's no fun for anyone hoping for aliens, but it is what it is.

>>7356064
Someone at the Planetary Society did a back of the envelope calculation and figured out that if Ceres' bulk composition was just 2.5% potassium, there would be sufficient heat generated by radioactivity to support a liquid subsurface ocean.

>>7356116

Where have "they" said that? NASA believes that reflective ice or salt is the most likely candidate but "they" don't know what it is.

>assuming that outer-system formed Ceres has the same ratio of Potassium as Earth...

>>7356123

It's a mild assumption, but I also remembered the wrong number for requisite bulk composition. It needs <0.4% potassium to have sufficient heat transfer, not 2.5%.

>>7356122

Revised.

>A highly reflective material is responsible for these spots -- ice and salt are leading possibilities, but scientists are considering other options, too.

It's not a hard statement to parse. They say it's a reflective feature, but they're not sure what the reflective material is.

>>7356132

That's an assumption, I've yet to see evidence that it's only reflective other than it couldn't possibly be luminous.

>>7356135

If it's not good enough for you, I don't know what to tell you. If NASA or one of the university science teams comes out with a geological explanation that leaves you shouting "it's a cover-up," please remember to take it to >>>/x/

>>7356135
>I've yet to see evidence that it's only reflective other than it couldn't possibly be luminous.
It gets brighter as it gets more sun exposure.

>>7356143

How about we wait until there's actual data besides anecdotes before saying what it could be? That's science right?

>>7356145
>Statements from ress releases made by the Jet Propulsion Lab regarding a mission they're running

>Anecdotes

Pick one; they're more professional than that.

It's an ET sculpture of their witnessing the Hiroshima and Nagasaki bombings.

>>7356149

They don't know what it is, therefore it's a guess.

>>7356143

>it's clearly swamp gas ignited by ball lightning move along tinfoil head :^)

>>7356152
They don't have to know what it is to recognize the effect of Ceres' rotation and the subsequent change in absolute brightness, in order to realize that it's reflecting, rather than emitting, light.

>>7356157

I've seen the same photos, that's contestable.

>>7356169
Have you seen images from the dark side or just from the terminator?
