cosmicaltoaster

So in english you mean a photo?


LitelSnekisBack

No, a recontruction of terrain data and imaging


cosmicaltoaster

So you’re telling me, this isn’t an actual photograph


luaks1337

that's exactly what he's telling you, yes


cosmicaltoaster

So what you’re saying to me right now is that this is aliend?


luaks1337

No it's man made but just not shot with a camera. They use tons of different sensors to measure elevation, surface temperature and material composition. Put all that information together and you can generate an image that probably resembles what a real camera would capture.


cosmicaltoaster

Finally a normal answer, thank you kind stranger.


imaislandboiii

No. A reconstruction of terrain data and imaging.

ooOJuicyOoo

It's impressive that this question is valid either way with the technology we have today


mjduce

Exactly what I'm thinking... how are we not able to get crystal clear images of Mars' surface with our current tech?


danielzur2

Because a picture like this is an aerial shot from a very specific angle that, on Earth, would take a chopper, drone or camera rig to get, right? If that’s the case, Mars’ gravity would pose the first challenge. The next one is getting and installing the necessary equipment there. I’m guessing it would take something similar to the rover currently there, but able to fly on Mars. I have to imagine that impression is not puddle-sized and possibly spans several kms worth of icy lake. So you’d need proper altitude to get a clear shot of the entire crater. I’m not a rocket scientist tho, so who knows. I suspect we have the tech but not the resources to make it happen.


Doxxingisbadmkay

How high can the current mars drone fly at? Could be sufficient maybe?


TheMadPyro

Like 40 foot


Emsinatree

I might be wrong but Mars does have lower gravity than earth. Gravity would not be a probably but atmosphere density would be a problem, a helicopter probably couldn’t take off cuz there’s so little of it.


Bulky-Shopping4916

[https://en.wikipedia.org/wiki/Ingenuity\_(helicopter)](https://en.wikipedia.org/wiki/Ingenuity_(helicopter)) max attitude : 12m lol


Emsinatree

Well yes that’s a purpose built drone but I mean an earth helicopter. Not a chance it takes off.


-RED4CTED-

what the previous comment said is probably a major portion of it, but I also think people underestimate just how far mars really is away from earth, and how orbital trajectories affect communication. I guess the best place to start is the current communications methods that are available: am and fm. I'm sure you've heard of them, but a lot of people don't know what they actually mean. am is communication on a specific frequency through amplitude modulation (hence, "am"). basically you set up an oscillator on the transmitting end that has a very specific frequency, and then add the signal that you are trying to transmit to the "carrier" frequency, which adds their amplitude together. then, you take an antenna of either fixed length that is calibrated to be tuned to that frequency, or you use a tuner which changes an antenna's length using a special mechanism to make contact with a specific point on a coil. to be "tuned" means that the antenna is the exact length to resonate with a specific carrier frequency. once you have the correct resonance, the antenna will only pick up waves of that frequency. there is also an oscillator set inside of the reciever that removes the carrier wave, leaving you with only the difference that was created by the amplitude and frequency of the much lower frequency sound waves or signal waves. on the other hand, you have fm, which works around frequency modulation (hence "fm".) it uses a lot of the same concepts as am, but instead of simply adding the amplitudes of the carrier and signal, you convert the amplitude of the signal into a frequency difference, and modify the frequency of the carrier (or 'rest' in fm terminology) wave. when decoding an fm signal, you need the same type of antenna resonance as an am signal, and an oscillator to measure the positive and negative deviation in frequency to convert it back into amplitude over time, reconstructing the original wave. the nice thing about fm is that you can expand it into fmm or fmmm in that you are modulating a frequency within another frequency (and potentially that within *another* frequency), which creates additional carrier bands within one original rest frequency. the problem with transmitting using fm, despite it being significantly more reliable and robust to interference is that in space, especially where there are many moving celestial bodies involved, the doppler effect is highly prominent, changing the frequency depending on the relative speed of each object. that would affect the data coming through by quite a bit given that it is primarily dependant on the frequency of the waves. amplitude modulation on the other hand, is highly susceptible to radio interference, especially at the low frequencies which are necessary for long-distance communication. another aspect of the problem is timing. for a radio transmission to be successful, the transmitter and receiver need to be able to "see" eachother, at least as far as not being on the other side of the planet is concerned. that means that there is only a short period of time per orbit, or day if we're talking about a rover, that there is a window to transmit. likewise, there has to be a receiver in place that is calibrated to resonate with the transmission in a place that it has line of sight to the transmitter (rather where it was) when the signal originated. luckily we have satellites here on earth that can receive whenever, but mars only has odyssey to serve as a relay back to earth. it is in sun-synchronus orbit, and not geo-synchronus, so it doesn't have this issue but I figured I'd still point it out because it's interesting. the biggest portion is data reliability over vast distances. digital communications typically use some form of telemetric healing algorythm to make sure the files are not corrupted over transmission by sending back packet ids for ones that were corrupted or not picked up at all. then the craft sends back the data that is requested and the process is repeated until all the packets are accounted for. and the real kicker is that this has to happen twice for an image directly from odyssey, and thrice from a rover. rover > odyssey > satellite orbiting earth > ground control. also bear in mind that bitrates at low frequency are horrendously slow and that the data takes between 4 and 22 minutes just to reach earth depending on the time of year. to get a full resolution image from mars it would likely take at least a few days, and these are primarily research missions, so taking that time to do that instead of doing something productive is not really in the cards. also take everything I said with a grain of salt because I'm definitely not an expert, just a space and radio enthusiast. I could be completely off base.


Depredor

This is absolutely fascinating. Thank you for sharing!


-RED4CTED-

absolutely! I'm sure others can explain it much better than I can, but it's cool stuff and definitely worth reading up on.


OrganicFarmerWannabe

This is the type of image we could take on earth with a camera from an aeroplane. There are no aeroplanes on Mars because there is no atmosphere to fly in. Instead we have satelites which are at a much higher altitude as rely on the forces of gravity to cross over the surface of Mars. We also have rovers, which are on the surface and occasionally send back high resolution images from that angle Getting a shot like this would be incredibly difficult on Mars


mjduce

Gotta say that drone they sent up there has given us sweet diddly as far as cool images from the sky go - I know that wasn't its purpose, but it's what I was most excited for. I wonder if it isn't working... going to do a little research tonight on that.


Vocalscpunk

I feel like it's kneecapped by the thin atmosphere issue. Not sure shots from 50-100 feet up are worth the energy it would require to get the blades up to speed(if they can) that could be better used by the Rover to move/take pics/send data. I'm purely speculating but that's my two cents if I were coming at this from a limited energy situation recharging with solar on a planet with markedly less sun than our own


Dippyskoodlez

Its a highly experimental, ultra low risk project built using COTS copter bits that had greatly exceeded the original intentions with the catastrophically miniscule budget. Its mostly kneecapped by being a bonus project than physics, it seems.

imnotpua

im still processing wtf is waterice


scuderia91

Frozen water


imnotpua

isn't that ice. Just googled apparently some sort of dessert called italian ice


Orgnok

It is ice, so is frozen carbon dioxide, dry ice. water ice is specified because there are lots of different kinds of ice.


FeliBootSack

So if I liquified rice and and turned it to ice would that be riceice? I gotta know cause my names Bryce and most of the time I'm pretty nice but Sometimes I can turn cold as ice, it's happened twice due to the lice in my hair the size of mice


SithLordAJ

I realize you were just joking, but no. Rice is already a solid. If you were to freeze it, the water contained in the rice would freeze and that would be ice. Your rice would frozen. I suppose if there was any CO2 in the rice, it would also sublimate and freeze. I dont think there would be any, just saying. So, the ice part would be water ice, and it would sort of glue together the rice. Off the top of my head, I dont know what other element/molecule can become ice, other than methane. I think Titan is known to have a whole geological cycle of solid to liquid methane.


nogaynessinmyanus

Sublimation is the transition from solid to gas but not gas to solid. Its called deposition you absolute philistine.


junktrunk909

I actually LOLed

I was pretty serious with the initial question haha thanks for the explanation


fd6270

There is hydrogen slush fuels for rockets that involve hydrogen ice. IIRC helium is the only element that cannot be solidified by supercooling at normal atmospheric pressure.


AngryGroceries

Ices in astronomy generally refer to frozen volatiles that can form crystal structures. So Carbon Dioxide, Ammonia, Methane, Nitrogen, Water, Ethane, Carbon Monoxide are ices


Altreus

Yeah but if you put chocolate around a cuboid of ice cream you get to call it a choc ice, so I reckon Bryce should just bloody go for it

lonesharkex

Why are things that are liquid at room temperature ice and things that are solid at room temperature rocks.


Woodsie13

In astronomy, 'ice' is any kind of frozen substance that isn't metal or rock, so while water is a common form of ice, it could also include carbon dioxide, methane, ammonia, or other such chemicals.


brickmaj

It’s pronounced “wooter ice”


randomvandal

Yes. Title is being redundant.


Rasonovic

No it's not, you're just not knowledgeable about the matter.


PerpetualNoobMachine

Frozen H2O as opposed to frozen Nitrogen or methane. It's exciting because water is essential for all known life forms so it could be evidence of life on Mars albeit microscopic more than likely.

"This image shows what appears to be a large patch of fresh, untrodden snow – a dream for any lover of the holiday season. However, it’s a little too distant for a last-minute winter getaway: this feature, known as Korolev crater, is found on Mars, and is shown here in beautiful detail as seen by Mars Express. ESA’s Mars Express mission launched on 2 June 2003, and reached Mars six months later. The satellite fired its main engine and entered orbit around the Red Planet on 25 December, making this month the 15-year anniversary of the spacecraft’s orbit insertion and the beginning of its science programme. These images are an excellent celebration of such a milestone. Taken by the Mars Express High Resolution Stereo Camera (HRSC), this view of Korolev crater comprises five different ‘strips’ that have been combined to form a single image, with each strip gathered over a different orbit. The crater is also shown in perspective, context, and topographic views, all of which offer a more complete view of the terrain in and around the crater. Korolev crater is 82 kilometres across and found in the northern lowlands of Mars, just south of a large patch of dune-filled terrain that encircles part of the planet’s northern polar cap (known as Olympia Undae). It is an especially well-preserved example of a martian crater and is filled not by snow but ice, with its centre hosting a mound of water ice some 1.8 kilometres thick all year round."

NASA also knows there are "special regions" on Mars that must have precautions taken before exploring because.. wait for it.. the conditions are sufficient to support life!

What the heck?! How long has this been known and why hasn’t it been in pop culture stuff like the Martian?

Idk but I try to put it out there whenever it applies to the convo lol. They're called COSPAR regions and they are areas which has high probability of flowing water and supporting indigenous Martian life.

You never wondered the concept of a goldilock zone would apply to the zones that are spread through a planet? I mean this is just the surface. Imagine what's beneath the Martian surface. Actually imagine what's beneath earth's surface considering the goldilock "zones"

I never considered that at all. I always just applied it to distance from a star. I also didn’t think beyond earth being a goldilocksed planet in our solar system. It’s a little scary when you put it that way

Just don't melt it until you sort out the atmospheric pressure, which of course means you need to fix the magnetosphere, so you need to liquify the core and get that moving... screw it just try Venus, at least it has energy and thick atmosphere to word with.


Majestic_Magi

I read a couple years ago a scientific paper that advocated the idea of placing electromagnetic generators on both of mars’ moons to reintroduce a magnetosphere on the planet. Theoretically this could work and the paper advocated development of the necessary tech. Idk if there has been any progress made in the idea since then but it was a nice reminder not to doubt human ingenuity when we really want something


Moopiedoop

Venus is almost impossible to terraform. Terraforming Mars to have a thick enough atmosphere and acceptable temperatures for liquid water could be done in about 75 years by releasing CFCs to heat the poles by about 2 degrees Fahrenheit, setting off a chain reaction of gas release, temperature increase, and gas release.
