I truly appreciate the ESA and their efforts.
Wow...that is one insane precision. Great video!
Not going to lie most of that went right over my head but it was still very interesting! :D
Thank you!
More! Great video.
MindBlown
Amazing.
thank you for this video
Awesome
love it!
Impressive
This space music is groovy!
Great stuff.
I'm surprised that this would be the first attempt at near-visible optical communication systems to remote space objects. After all, the Apollo program left mirrors on the moon surface so that terrestrial lasers could be used to measure the earth-moon distance very precisely. Astronomers have been using lasers to undo the effects atmospheric distortion on imagery from decades as well.
The ISS astronauts orbiting the planet for months, have dial-up type of connection (speed wise) and they're performing tons of experiments. They should have the best internet connection in the world. Not the worse ffs.
We ♥esa♥.
I still find it hard to believe they can actually communicate with a robot on mars...much less DEEP SPACE! When we're barley able to go anywhere with a cell phone
It's all about the power output. There is an output power limit that has been decided by many countries to make sure it doesn't cause damage or interference (Think of an EMP).
That and you know.. there are no trees or hills in space so it's all about turning the power output to the max
@Dave Micolichek Well antenna design will give you a tradeof between gain and pickup area. You can only do so much to maximize an antenna's efficiency. The rest is up to transmission power. Space probes are usually running with solar power support or even nuclear. You usually don't have a capacity problem, just a current limit problem so you wouldn't for instance transmit data while another part of the probe is sampling.
@Dave Micolichek Clearly you haven't read what I said properly. Let me rephrase it so you understand. It would not be possible to reach that far without those 20Watts. 20Watts is quite a lot of transmission power. Lower power would make it more prone to data loss, and having to retransmit would take forever. You keep repeating that power is irrelevant and only antenna matters, which is inherently wrong. Or they might as well use 1mw. One of the reasons is the low frequency used along with a prooerly tuned antenna and good transmission power.
@Dave Micolichek You're clearly living in your own bubble. The antenna design is part of what determines the power output in terms of gain. You seriously can't compare conditions on earth with tons of objects blocking and weakening the signal, along with the earths curvature, and something communicating in a straight line without a ton of objects interfering. So no you have absolutely not understood what I have said. Your arrogance only makes you think so. I never said that the watts consumed is the main reason for its long range communication. I said POWER OUTPUT, do I need to repeat that? Power output is multiplied by the antenna gain. Antenna shapes can help dampen the effect of nearby objects that could corrupt the data. I know full well that the antenna design is important and I have not denied it. You also can't compare cell phones with gigahertz frequencies and a space probe transmitting at less than 110MHz.
Have you ever known a consumer device to ever have an efficient antenna?
more!
input cavity resonator ...right away captain
can we make repeditores como en los sistemas de elecomunicasione repetidores o bateria
I Would Love To Have That Antenna
For banking ?
im just here to read all the flat earthers comment.
I know.. it’s really too much. I just watched the Logan Paul video with the founder of the Flat Earth conference and the guy says “What magical wifi are they using?”. At first (due to my ignorance on the subject), it made me think. But then as a rational human being I researched it and understood thaf WiFi and the signals they are using obviously have nothing to do with each other. And here is the problem, these people are so deep into their delusion that they out right decline to research and learn.
@@chinadashauthority65 why did you paste this twice? What does wifi have to do with anything you're talking about?
Anyone can launch a satellite using Software Defined Radios, without the need of much hardware, and also given the fact that launch costs are so low that uni students do hobby projects.
Flat earthers should just see it for themselves by launching a satellite, and the next thing, they won't be flat earthers; but guess what, the founder will come up with another illogical argument to keep the lucrative profiting from conferences they organize.
@@first_last- Wifi is also radio

06:00 AHH Alligator logo shirt to popular in the 80's I had some.
How much is that?
I want buy 25 pcs
in my village i dont have range for vodafone😪😪😪
MORE MORE MORE!!!
We all know how a traveling wave tube amplifier works . It’s just like the great pyramid of Giza . The “kings chamber “was the resonant cavity. A communication device including mass data. It is Mass Data means teleportation. If you Can you find the whereabouts of the electron in a mass then you can entangle it to another location. Noooo?
WOW

No
Ur brain is flat (no offence). JK
Sorry
Can you tell us How It Works plz?
It's like knowing how fragile a brain is and shaking it by humming that's a killer with no trace
very interesting , I'll be glad if Someone can help me with my doubt ..why does the beam become narrower when we go for optical communication ?
optical communication requires higher data rates, which requires higher bandwidth, to achieve that you have to raise the frequency of the transmission which implies smaller wave lenghts (narrow beam)
that's why satellites are making a transition to fpga technology, that is hardware that can be re designed after being sent to space

Right...But what band is the best to communication with mars? Ah 08:13 is what I came here for.
Can we send radio or video signals from the surface of earth directly to the surface of mars?
The accent of Mr Lanucara makes it so hard to understand some parts of the video. can't you perhaps provide subtitles? I would certainly appreciate it.
honestly i find him perfectly clear, despite the strong italian accent
Thats exactly what I dropped down to say. The english subtitle during his talk makes no sense.
@John Cass c'est assez égocentrique de ta part de dire ça et de plus rédigé en caractères gras, bravo mon ami. Le dude n'a pas du tout été impoli, si c'était le cas je ne dis pas.
Why not use lasers? Wouldn't that be a much faster way of communication since it would be traveling at the speed of light?
Hmm? All electromagnetic radiation travels at the speed of light. Laser communication has its advantages in some areas, but speed would not be the issue.
I love how all the video of space is cartoons. No video of their hundreds of satellites in space
Shane So you want them to launch cameras that fly around in deep space filming the satellites themselves? Maybe this area of knowledge is not so good for you, huh?
Exatctly, why CGI and no real photos or videos, is not that hard, unless you want to fake space.
I know right, they could debunk this all sooooooo easily, just point the camera at the screen that shows the satellite direct feed uplink, remote control the camera on the satellite up down left right, zoom in on the Earth and show us all it's not a cartoon.
Shane Don’t be silly. We don’t have that kind of technology. 🤣🤣🤣. Ah yes, the nonsensical antics of “Space travel!”
they could make DEEP SPACE communication probes to see if they can contact another planet with life in it. just like in the video game "Space Engineers" you can do the same thing. like you can send probes out to like 50,000 meters apart so you can talk to your buddies on a different space station or ship from about 90,000 meters out. i wish that Microsoft would format the game for PlayStation consoles
What’s in that HIGH rate data?
Currently it is 75Mbit for lagrange points and up to 2 Mbit for mars.
In implementation and testing is over 200Mbit/s, K-band for lagrange points and optical for deep space.

If all the nations all over the world cooporate as 1nation and build a city in moon and other planets only the planets has lands and can live on and all the nations donate funds so they can build stations in other planets
But what about space pirates? I don't think you've fully thought this through. ;)

How do you triangulate the position of a space craft after it is out of the sattelites range? how do you know where to position the dish? i mean after the craft is on more than 2000 km away. Basicly to triangulate a position ull need at least 3 satelites for x,y axes and even more for the z axis. If you dont know its position in deep space how do you know where to look with the long range ultra directional antena with a angle of like 0.00000001 degree. It has to be precision of surgical or laser target. But on that far is more like imposible. Thats why space is a joke. Nothing went into deep space. I mean litterally nothing went higher than like 80km where the iss is. And is not fken 400km away is like 80 max. Long range comunication are imposible beyond a specific point. I mean for directionallity of the antena. If the antenas are omnidirectional is easyer (and would explain a lot of things) but ull need a lot of power to make it. Nowhere is said that they use omni antenas, only directional dishes, or yaggy's.
And btw, those huge antenas to receive the signal are one way, we listen to a spacecraft but spacecraft dont listen to earth. To listen it will have to have same strong antena on it. Imagine if on ground ull have a 100 feet antena ull have to have same 100 feet antena on the spacecraft and it to target (face) the earth's ground antena. Is the only way to work.
Either way is imposible to achive.
people who think something is impossible should stay out of the way of those making it happen
can't remember who said that tho
That's some BS, do you always have such elaborate opinions on things you know nothing about?
Antennas on earth are much larger than on spacecraft and it works, because the larger Antenna can both pick up the weak signal of the smaller Antenna and send at much higher power so the signal is strong enough to be received by the spacecrafts small antenna.
This has NOTHING to do with deep space if they are talking about craft INSIDE the solar system.
trust me... it is deep and it is space
Martin
NO IT ISN'T
greywolf424 well go show me
Martin
INSIDE THE SOLAR SYSTEM IS NOT FUCKING DEEP SPACE
greywolf424 ehm... yes it is? there are also deep waters in ocean but that doesnt mean theres not deep water in alakes.... its not meant here to be THE deep space... its just deep space... its space and it is far away thus to be called deep
All thanks to Jewish home grown engineers & technology.
How voyager communcatio. Work ???? I find this bullsh!t
