Great potatoberg released this ad. IMHO it falls into the Starship troopers category of 'intended satire but unintentionally cool as fuck', if only they'd left out the last 3 seconds of muh climate change. fuck earf.

>>12719711
Doesn't really matter, the satire of starship troopers unironically made fascism look good.
Wondering where they got all those landscape backgrounds though. Is there 3D mapping out there or did they just make it up.

>Bro lol the 1% are just going to leave us and go to Mars

These "people" are so insufferably retarded it's almost hard to believe. Yeah bro like Bill Gates and Jeff Bezos are going to leave their gorillion dollar superyacht, teenager fucking lifestyle on earth to go live in a pod on Mars?

Do these imbeciles have any idea of the scales of economics and infrastructure development it would require on Mars for these Jews to have that same lifestyle on an airless radioactive desert shithole?

>>12719743
Colonizing Mars is going to be fucking hell, but a hell I welcome over the hell I have on this planet.

>>12719746
Me too my man.

>>12719743
It's hilarious the angle they try to play on it. I don't think they are that stupid when writing it they just know their audience is dumb enough to believe it's a class war thing.

>>12719746
It’ll be cozy in its own way. Do you think it would be better to find a tradwife before blasting off to the red planet? Or should you wait until you get there? I doubt there will be too many single cuties going there until it turns into a self-sufficient vacation city in 100 years

>>12719760
Tradwives come included with the deal.

>>12719760
You won't find a women willing to leave urf and go to Mars with you, well maybe one in several million but good luck with that. Mars is going to have a serious female shortage. Hopefully we can just cut straight to artificial wombs and robowives.

What about fog?
Checkmate.

>>12719768
Water is literally a lighter-than-air vapor, anon. Not even by just a little bit either.

>>12720058
Fog is made of condensation. It's tiny droplets of liquid water, which are many times more dense than air, but so small that they remain suspended through the brownian motion of gas particles. When the sun hits fog it begins to rise because the droplets begin to vaporize again and create a layer of lower density gas mixture which floats on dry air.
Clouds happen when warmer surface temperatures prevent the condensation of water, allowing the water vapor to rise much higher before expanding and cooling enough to form droplets. Clouds themselves are a transient thing, and can only persist for as long as the plume of water vapor rising underneath continues feeding them. Otherwise clouds eventually warm up in the sun and all that water re-evaporates.

Stupid question approaching.
If you somehow find yourself in in interstellar or intergalactic space and look at your hands:
Will you see them? Are they in the dark? Will you see a shadow or are you well lit from all sides?

>>12720086
Same here, fuck that shit just gonna watch when I wake up.

>>12720104
>much like InSight used the SkyCrane dropoff method too
False

>>12720120
>False
You're correct, I'm retarded, it parachuted down and used on-board thrusters to land.

>>12720112
Interstellar you could see okay. You would be dimly lit from all sides.
Intergalactic good luck buddy.
It depends on where you are though. I assume you mean in the farthest depths between galaxies. With interstellar, the brightness would depend where you are in the galaxy.

>>12720086
Gonna be a while until the next one, so the question is do you consider it worthwhile to get up early to watch it or not?

>>12720112
You have never experienced a moonless night in the countryside have you

>>12720138
I guess it depends on what we're going to see.
If they provide telemetry, that will be fun. But if it's just some dude giving a thumbs-up, that wouldn't be very exciting.

Dude, yeah? If you block out the Sun and there are no other sources of scattered light around (ie no moon) then you are effectively seeing exactly what you'd see if you were 4 light years from the nearest star. Except slightly less if you're under Earth's atmosphere, so try to get above most of that.

How long until the Mars landing

>>12720311
there won't be a mars landing
it appears that Percy had a collision with a tesla roadster and now mars orbit is kesslered for decades to come

>>12720156
I think so too. odds are not good for a successful mars landing

So when's the landing in EST?

Stop talking to that retard, how in the fuck do you not get how shitty trolling works? Anon says dumb thing, you are upset at dumb thing, anon doubles down, you reply again and before you know it the thread has derailed because you couldn't just ignore someone who was being a faggot.
They're being a faggot specifically to get your reply btw, you have to already know this so why continue

>>12720360
It is 5 hours away. Make sure to press the "NOW" button on the bottom for current date/time/speed

>>12720358
I love how the landing site has no LOD so you can see that it's fully detailed from hundreds of miles away.
Also they should've just done it in KSP.

>>12720363
where is this "NOW" button?

>>12720145
They will provide telemetry. An orbiter is passing overhead when it lands, and it can relay some basic data back to earth which they will use to simulate how the landing is progressing.

Sorry anon I've just heard that one enough times to be sick of it by now, nothing personnel.
>>12720399

>>12720384
The only thing useful about it I can imagine is it acting as a shielded space station/port.
Would suck though because you get all the drawbacks of lunar regolith but without the handy light gravity.

will there be a livestream of the descent?

>>12720421
>>12720417

>>12720422
no i meant will there be a video feed

>>12720421
The first thing we're likely to see is the hazcam photos, those were the first published from Curiosity landing.

>>12720427
It won't be livestreamed, it will be recorded from various view points and sent back to Earth in the coming days.

>>12720384
Its gonna crash in like 100k years or so and utterly fuck up the whole planet. Any Mars colony is going to have to find a way to deal with that shit eventually, although it's still a massive time frame from human perspective.

Best idea I've heard is using Phobos as a massive orbital/spin tether that can yeet ships either into the inner system or out to the outer system.

>>12720421
>>12720427
there will be a livestream of telemetry presented as a simulation, the video feed we'll get a few days later (with sound too)

>>12720427
no, they don't have the bandwidth to stream back live video

>>12720421
estronaut will do one for example

>>12720430
>100k years
30-50 million years*

>>12720434
also if it were streamed it would still be like 10 minutes later so not live but "live"

>>12720430
Won't it break up and create a debris ring since it seems to be just rubble held up together?

>>12720442
>>12720434
they streamed the moon landing tho

>>12720444
yes but the moon is at some light seconds of distance you absolute retard

>>12720444
you don't need the DSN to get data from the moon

>>12720444
That's like 2 light-seconds away, Mars is 7 light-minutes away.

>>12720441
Nvm excuse my retardation.
I still think Mars is going to wind up as the Solar Systems designated truck stop complete with space diners and space hookers in the Starship weigh stations.

>>12720447
i can take a 10fps 7 minute delay feed

>>12720082
>>12720089
this landing will prove or disprove the viability of the skycrane. If Percy lands safely that will point to the maneuver being reliable and it may just become the default way of landing rovers on the planet.

>>12720451
Would still take a monumental level of comm infrastructure and power to achieve that from Mars.

>>12720384
>>12720407
Phobos is where we are going to develop capabilities like microgravity industry and asteroid mining. It's in an ideal location for this. It will also be a hugely valuable stockpile of resources for extraction and refining into products like enormous spacecraft and habitats.

>>12720089
There is one major difference. It will take photos of the Mars ground and compare it to previously taken orbital imagery to narrow down the safest landing spot and maneuver to that location before final touchdown. Per JPL update yesterday.

>>12720455
will it do all that on its own?

>>12720443
Yes it would do that. In fact it would be broken up by tidal forces before reaching the planet even if if were a monolithic chunk of rock today.

>>12720452
>become the default
Yeah, until spacex does a rover rideshare program with a starship and dumps 30 rovers on the surface at the same time.

>>12720447
>>12720451
>>12720453
Aren't they already working on internet protocols for interplanetary internet?

Just steam it on facebook.

>>12720461
Yes. They programmed it to run its own imagery recognition and calculate it while still descending. They tested it with helicopters over Death Valley.

>>12720452
Starship will be the default way of landing everything on Mars.

>>12720430
>100k years
more like 30 million years

>>12720451
Just wait a little bit and we'll have HD video with sound. Unless I'm there I don't expect to be able to watch it real-time.

>but what about irradiating mars and its atmosphere
nigga, who cares

Guys how much effort to move Phobos and Deimos both to Mars-synchronous orbit and mash them together into one slightly bigger moon which will remain in a permanently stable orbit?
Can we use plasma magnet sails close to Mars since there's no magnetosphere? Could we use sequential tugs via a magnet sail to give little delta Vs to the moons over many years?

>>12720483
Would it be a good idea to irradiate the spot you're skycraning buildings down on? My gut says 'no' but I've been wrong before.

>>12720470
Why would you need a skycrane at all when you can just put hundreds of tons on the surface normally? Skycranes are just a way to cope with mass restriction.

>>12720483
>but what about irradiating mars and its atmosphere
>nigga, who cares
Irradiation and contamination are not the same thing. You can blast an apple with 100 sieverts of beta radiation and eat it like any other apple. However if you contaminate that apple with a microgram of polonium-210 you're gonna get a severe internal dose to your bone marrow and soft tissues. Likewise if you contaminate the soil and ice on Mars with fission products and activation products (from the neutron flux) you're going to make it annoying to avoid pulling radioactive shit into your habitats.

>>12720108
maybe because the video never says that bezos and musk are going to live on mars themselves? and that hardly matters anyways, even if the 1% poorest people go most people are still fucked on earth. the video isn't saying colonizing mars is bad, it's just saying it's no replacement for taking care of earth, why can't none of you retards understand that

>>12720501
see >>12720506
Irradiation is fine. Contamination is not. The NSWR spews shitloads of contamination so it's pretty "meh" for launch or landing on objects you plan on mining anything out of.

>>12720507
The video description literally says that the world's richest and most influential people are "laser focused" on Mars and not doing anything for Earth. Meanwhile Elon is probably the single most influential person right now in terms of actually doing shit about getting away from fossil fuels.

>>12720507
>why can't none of you retards understand that
Why can't you understand that painting Mars and space in general as something for the rich to use to escape is going to make people hate the very idea of it and try to shut it down?

>>12720521
>and not doing anything for earth
so you just can't read then

>>12720523
going to mars is neat for scientific discoveries, to push the boundaries of humanity and all, i still think it's dope, i'm just not deluded into thinking it'll solve all our problems on earth

>>12720507
This whole "1%" is the most retarded shit ever. They got any idea what 1% of the population entails? And if it's meant to address exclusively some of the richest people, it ignores the overwhelming fact that life on any other celestial body would be extremely tough and without one hundredth of the benefits available here. It is meant exclusively to spark outrage, trying to point a finger to people interested in space program developments and accusing them of promoting a quite literally impossible "escape" from an ever changing planet that is not going to magically burst up in flames in 10 years. Well, subterranean methane pockets bursting aside, but that's not happening either.

Reminder that all defence of anti-space propaganda is low quality bait.

>>12720525

>>12720533
and yet many here spend their days making plans for how they want the mars colony they'll definitely be a part of to be like

>>12720513
Zubrin's mars hopper isn't a NSWR, it's just a NERVA-type solid core reactor that uses an air compressor to turn mars atmosphere into liquid CO2 for reaction mass.

>>12720539
Yes.

Not that soon, I meant to say. Certainly not within anyone's of us lifespans. Right?

>he said, as if the Mars colonization efforts will not be heavily reliant on R&D work performed on Earth

>>12720546
make me sneed, daddy

>>12720544
Correct, I know. But the other anon said NSWR so I ran with that. That being said a nuclear thermal rocket does have some implications for activating the surrounding soil through neutron flux and activating the vehicle components as well, though this risk is comparatively small due to the much lower neutron flux in a solid core reactor vs an open cycle continuous supercriticality fission torch.

>>12720550

it /is/ fine. what's not fine is saying that climate change doesn't matter and earth can go fuck itself because humanity can just move to mars, which i'm pretty sure is what the video is trying to oppose

>>12720565
Imagine the smell.

>>12720580
You've completely fallen for what the video is actually trying to do: It's masquerading as simply being against ignoring Earth while using that in an attempt to whip people up into a frenzy over spaceflight itself.

Space elevators just can't win.

>>12720635
so the latter. Yeah, that's what I figured. It just looks like it's off course even though I know its not.

If the supersonic parachute fails to deploy, can the booster crane slow down enough to land safely?

>>12720659
yes

>>12720659
no

>>12720659
maybe

>>12720659
I don't know

>>12720648
It is currently facing its solar panels directly at the sun and best communication angle towards Earth. Once it gets right over the Mars atmosphere it will use its RCS to orient itself for hitting the atmosphere head on

>>12720659
No. Not enough TWR and deltaV. The thrusters have no room for additional capacity from the last part of the landing.

So booster 1069 is going to be built this year, how do we convince SpaceX to paint "Rocket 69" on the side?
https://youtu.be/Hk6yqu2xFok

>>12720669
oh, well shit now that you explain it it sounds really obvious. Stupid of me to assume that its direction was the same as its orientation. Still, thanks for the explanation.

>>12720453
> Why no 4k footage now
> Just bump up the power bro
> wtf is the inverse square law
> it worked on the moon
zoomers pls

>>12720478
They aren't doing much different, basically reused most of curiosity, it's a bit heavier, has a heli underneath and is landing in worse terrain though.

>>12720669
It also starts dropping ballast weights to orient during the initial reentry, right?

>>12720691
I dunno, what is the inverse square law?

Altitude above surface, from 18:00 TDB (which roughly corresponds to UTC)
Down to 20:38, ~130km.

>>12720695
Yep there's actually two sets of ballasts. The first set gets jettisoned before atmospheric entry to raise the craft's center of mass and create a lifting body out of the capsule. They will then jettison a second set of ballasts before parachute deploy to balance the craft back to normal

>>12720695
>>12720701
I forgot to mention this one also has two additional cubesat- style relay satellites it will jettison before atmospheric entry to try out new method of data communication. These two cubesats will briefly relay data from the rover to orbiting satellites before burning up

>>12720700
Orbital Velocity on the same span.
Units are kilometres and m/s btw

>>12720700
>>12720707
Also rough simulation of dynamic pressure, from 100km above surface down to 8km.
Units km and kPa for pressure

>>12720706
I hadn't heard about those cubesats, they're tucked away on the cruise stage somewhere?

clearly they should just use the helicopter and autorotate to safety

>>12720720
So I may have gotten confused originally.. It's actually two cube sats that were deployed curing cruise and will pass Mars while relaying data to Earth
https://www.wsj.com/articles/headed-to-mars-a-big-experiment-in-tiny-satellites-1542891601

During one of the JPL press briefings I almost recall hearing they were also including some experimental communication/science device ballast on the backhel to either relay data or measure atmospheric data but can't find that info online right now

Huh, I'll assume they were stuck on the kick stage somewhere, since WSJ doesn't care to tell me.
That's neat though, I didn't know about this part of the mission. I wonder how long between Perseverance EDL and the cubesats entering, maybe MRO could be in position to snap a few pictures of them burning up? That'd be cool.

Make your guesses for what will happen at ETA-0 on this viewer-
>Model collides into Mars, disappears
>Model continues on trajectory through Mars
>Model follows real-time behavior, sheds spacecraft, sheds aeroshell, descends down to Mars

>>12720756
is Manley making a subtle nod to gassing the Jews here?

>>12720759
Model collides into mars and disappears, as the telemetry is tied to the coasting stage

WHAT'S A GOOD LIVESTREAM?

oi

>>12720698
radio wave propagation spreads out exponentially the further away you get from an object. The same transmitting power that we used to send images back from the moon would never be able to send images back from mars. It would take a retarded amount of power to broadcast video from mars back to earth. Infrastructure could be made so that its possible, but it would be a fucking monumental effort.

>>12720765
in fact it's not really "telemetry", it's an integration probably taken from JPL Horizons. If you take a look at the data there you will see that it propagates the trajectory as if there was no surface (the periapse is around 80 km below the surface). So for a couple minutes, it continues the hyperbolic trajectory, away from mars

>>12720756
Unexpected of him but nice, watching a few gulls get deep-fried on that barge would have been funny.

This site lets you view real time data downlink from space missions, including Perseverance (M20)
https://eyes.nasa.gov/dsn/dsn.html

The various Mars orbiters will also send data towards Earth stations.

>>12720765
>>12720784
here is the data, which any sort of visualization like that is probably working with:
8:38:00 PM 3519.93232
8:39:00 PM 3439.859479
8:40:00 PM 3378.138818
8:41:00 PM 3336.032971
8:42:00 PM 3314.462052
8:43:00 PM 3313.91701
8:44:00 PM 3334.410173
8:45:00 PM 3375.473922
8:46:00 PM 3436.20785
8:47:00 PM 3515.363984
8:48:00 PM 3611.452737
8:49:00 PM 3722.851254
8:50:00 PM 3847.899659
8:51:00 PM 3984.976946
8:52:00 PM 4132.554165

8:57:00 PM 4983.685797
8:58:00 PM 5169.621827
8:59:00 PM 5359.050191
9:00:00 PM 5551.42373


As you can see as it passes the periapse at around 8:43, it continues the trajectory.
Now, to know what a visualization does with that... depends on how it is programmed. My guess is that it will simply disappear. Programming the surface threshold is trivial. (or simply giving the data up to a point)

>>12720808
Makes sense, not expecting anything fancy

>>12720808
During the Curiosity landing in 2012, Eyes showed the different EDL stages down to landing in real time. Not sure if they programmed that on 2020

>>12720794

You can manipulate the time by changing the ?time tag in the URL.

SpaceX will certainly be autistic enough to include real-time true telemetry driven 3D visualizations on their website when they go to Mars, with full animations of everything present and correct.

Space elevators become useless for celestial objects at some point between Moon and Mars mass. Even if Mars only had one moon and it was basically a carbonaceous asteroid perfect for making carbon nanotubes out of, it would still not make economic sense to build a space elevator for Mars transport.
That being said, space elevators do actually become viable for moon-sized objects, even ones that spin slowly so long as they orbit a larger body, and for very tiny objects like Ceres they are fucking amazing. In an autistic fit a few threads ago I showed that in the same amount of time it would take a Starship to fully refuel and launch a maximum payload to Ceres orbit (13,000 tons), a space elevator on Ceres could lift over a million tons of material into Ceres-stationary orbit. It would also be perfectly fine to build such an elevator out of regular old steel, aluminum would be overkill in terms of strength to mass ratio, and at just 1000 km long sitting in a maximum of 0.03% of Earth gravity, climbing the cable up and back down would only take 48 hours total even with a load of 500,000 kilograms.

>>12720965
Is she okay?

>>12720977
There's a LEGO Curiosity model if you can track down an affordable set. Maybe LEGO will reissue it for Perseverance

Not long before Perseverance crosses Deimos' orbit

>>12720986
>1:1

how long is the light lag between here and mars right now?

>>12720998
7-8 minute signal delay

It will be on the ground by the time we get a signal that it hit the atmosphere

Any good stream for Perseverance? There is only women talking on NASA TV.

>>12720986
That's not terrible, but I'm not a huge LEGO guy.
I'd kill to have a little set of interconnecting pieces: cruise stage+backshell/heatshield+skycrane+rover.
>>12720998
DSN says 22 minutes round-trip right now.

>>12720977
is the landing stuff pre programmed? or does it have some AI shit for descent?

>>12721005
They will switch to mission control center 1-2 hours before landing
https://youtu.be/gm0b_ijaYMQ

>>12721009
some of both. It takes radar data of the surface as it's coming in to pick a landing spot

>>12721009
All preprogrammed - no commands from Earth. However, the program does include the use of sensors to adjust its course during atmospheric entry and final rocket descent to the best landing location.

hehehehe... blahem!

>>12721009
probably 90% preprogrammed and 10% AI

>>12720859
A lot more than we currently have. The solution is to set up an array of communication satellites (not anything crazy, maybe 6 maximum for now) which have the big beefy dishes and solar arrays needed to achieve that kind of bandwidth across interplanetary distances, then just have the probes and stuff transmit to those satellites. That way the stuff doing the flying only needs a reasonably amount of antenna power and we can get actual half-decent video (with much higher framerate and higher res video being dumped into storage for relaying afterwards).

i keep farting and stinky. is this really how elon powers his cock rocket? laughable

PERSERVERANCE WILL CRASH.
STARSHIP WILL NEVER GET TO ORBIT.
THERE WILL BE NO MARS COLONY.
HUMANS WILL ALL DIE ON THIS ROCK.

>>12721009
Point of insertion and deployment are probably preprogrammed. Terminal adjustment and the landing burn will be handled by avionics supported by active sensors.

any cool other apps/websites besides that 3D solar system from NASA?

>>12721039
do u fart?

>>12721030
No, only india would power a rocket with uh oh stinky methanethiol.
Methane is completely odorless. They add a few parts per billion of methanethiol to the gas inside of utility lines to make it smell.
Your ass produces thiols and other sulfur compounds, you nasty nasty creature.

>>12721026
So basically multiple satellites each carrying some of the data?

>>12721039
Finally someone with sense in this whole damned thread

>>12720992
Yep. Closest approach to the rock will happen in around 76 minutes tho. At the node marked by the white discontinous line.

Of course, take in account that there will be a communications delay

>>12721069
>he didn't get a front-row seat on the rover

lol

>>12721053
Well, more like probe -> Communication satellite -> Earth based receiver.

The only reason you need multiple communication satellites is to guarantee that you always have line-of-sight to at least one of them at all times. At any one time though all of the data would be passing through one satellite on its way to Earth. In the worst case scenario, the probe would talk to a satellite, which would relay the data to one of the other satellites surrounding Mars in the event that Mars was blocking the line of sight to Earth, and then this second communication satellite would beam the data at Earth from there.

>>12721069

I'd just like to interject for a moment. What you're referring to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called "Linux", and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.

There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called "Linux" distributions are really distributions of GNU/Linux.
