How Do scientists communicate with NASA's James Webb Space Telescope?

Have you ever wondered, How scientists communicate with Webb or even any other Telescope?
Many of NASA’s spacecraft are exploring our planet, our solar system and beyond.
These Spacecrafts send information and pictures back to Earth using the Deep Space Network, or DSN.
The DSN is a collection of big radio antennas in different parts of the world.
There are DSN locations near Canberra, Australia; Madrid, Spain; and Goldstone, California. Those sites are almost evenly spaced around the planet. That means as the Earth turns, we never lose sight of a spacecraft.
When any Spacecraft send images and other information to these big antennas here on Earth. The antennas also receive details about where the spacecraft is and how it is doing. At the same time, NASA uses the DSN to send lists of instructions out to the spacecraft.
But in order to communicate with the DSN, the robotic explorers have a lot to do. The tools they use to communicate can’t be too heavy, take up too much room, or use too much power. Small antennas on the spacecraft can beam weak radio signals back to Earth.
The farther away a spacecraft is, the larger the antenna you need to detect its signal. The largest antenna at each DSN site is 70 meters (230 feet) in diameter.
The most distant objects that the DSN communicates with are NASA’s two Voyager spacecraft.
Because the Voyagers are so far away, their signals to the antennas are very weak. In fact, the power that the DSN antennas receive from the Voyager signals is 20 billion times weaker than what is needed to run a digital watch! Engineers have figured out ways to boost those signals so they can be “heard” loud and clear.
However; once the DSN antennas receive the signals, Centers at each DSN site receive incoming information. Then, they send it to the Space Flight Operations Facility.
So the short answer is:
Webb is sending science and engineering data to Earth using a high-frequency radio transmitter.
Then, The Large radio antennas that are part of the NASA Deep Space Network will receive the signals and forward them to the Webb Science and Operation Center at the Space Telescope Science Institute in Baltimore, Maryland, USA.

So only one real comment, but anyways it is quite amazing they can still communicate with the Voyagers.

[@johnross4576]

***spoiler alert*** they use a really long string and 2 cans

[@TomadurBaLal]

[@jonathonschott]

My money is on the longest tin can and string ever invented. I believe in you NASA.

[@stephanienoire1892]

So it's radio waves? Wow what can't those radio waves do

[@joshuaforbus5853]

A taunt cotton string. If taunt isn't a word?I'm going to feel really stupid. Semper Fi

[@bio1m6]

I didn't understand

[@briansmutti]

can you please remove the repetitive and annoying music? it distracts from the quality of the video

[@drsiva6618]

So the signals now recieved arent what they actually are, and what would be the time laps of real position of James Webb and the data you've got? Have you ever calculated in accurate?

[@joshuaforbus5853]

Nuclear decay and a mission plan older then my oldest child.

[@hossin2732]

اگه این دو ویجر به دورترین نقطه کیهان برسن یعنی ۱۳نیم میلیارد سال نوری هم باشه بازهم میتونن به زمین پیام تصویر ارسال کنن چون یه الکترو مغناطیسی درعالم وجود داره که دائما درحال رفت وبرگشت در عالمه و هر پیام رادیویی با این موج ها برخورد داشته باشن یه جورایی میشن مسافر این الکترونها،،،، شاید پیام درست نرسه ولی به هر حال میرسه به زمین ....البته زمان رسیدن پیام بستگی به فاصله اون ویجرهابا زمین دارد

[@MrWireguy]

"high frquency" ??? as in 3 to 30 Mhz. Probably not.

[@h.dejong2531]

you're right, JWST downlink is at ~8 GHz.

[@MrWireguy]

@@h.dejong2531 I guess "high frequency" is a very relative term depending on when you were born !

[@brettsolway5089]

Can-Bare-Row Australia??? Or Canberra, pronunciation - Kan-bruh?? FFS get it right!!

[@DrLogical987]

1:42 I'm pretty sure the signal from the jwst to earth does not get transmitted from the observation equipment

[@Jr_Scientist]

By sending many images

[@joshuaforbus5853]

Bravado

[@Lucius_Chiaraviglio]

The last photos show the antennas on the bottom of JWST, but the animation before that shows it using the telescope mirror as an antenna to send signals back to Earth. Who thought THAT up?

[@DrLogical987]

The graphic artist of the video?

[@jaykoni]

But the moon is in the way of signals.

[@arielperez797]

hmmm...the moon orbits the earth though. so sometimes it probably blocks the signal...but other times it doesnt. thats how i imagine it.
wonder if the signal is weaker when we are on the opposite side of the sun.

[@jaykoni]

@@arielperez797 I confused the Earth/Moon L2 with the Earth/Sun L2. My error.
