Deep Space Network: How we receive images from spacecraft

There are lots of awesome pictures of the planets in our solar system. We have the these pictures because of the amazing spacecraft we've sent there. But one component that's overlooked the underlying communication network that gets the image from the spacecraft to our computer or mobile screen. Today we'll look at the Deep Space Network.

This is Celestial Sphere. A brand new series that looks at spacecraft, planets and their support system.

If you like small YouTube science channels check out the subreddit I've created just for that.
Give these guys some love.

I've worked in radio communication and I still learned a lot from this, thank you

[natepremium]

I still don’t really get it. As far as I’m concerned the explanation is, “radio waves, dipty-doo, rooty tooty too, they’re back on earth!!!” 🤯

[erickillian]

Thank you for this. I was trying to find exactly this answer and your video was the only one of four that I watched that answered it. Please keep making content, I'm going to check out your other stuff now.

The DSN is the unsung hero of so much of our exploration of the solar system. I hope some day a huge array of antennae in orbit will form an array even better and more reliable.

Appreciation timeee, I'm so glad I found your channel, quality, straight-forward and visually appealing content, really imformative.

This video is just amazing! Such a deep & easy way to explain. Thanks alot

[alexandregaeng]

Thank you for the video. Just to be sure to correctly understand (because English is not my mother tongue), I try to summarize what you said. We use big dish to focus the weak signal at a subreflector which reflects it to a waveguide and then it reaches at the base of the structure an antenna and a complex receiver which amplifies and processes the signal, then records data on hard disks before sending it to scientists through the internet, am I right ?

found this video on the date of the JWST launch (12/25/21). great info as it appears not too much has changed

[vikrantvijit]

Brilliant presentation with perfect content articulation, creative visualization and cognitive conception.

[shikhabhardwaj]

Excellent explanation and editing. Keep it up 👍. Love from India

[aggoldstein]

Great video.Can you do one on how instructions are sent to something like voyager?

[ARWest-bpyb]

All the more amazing when you consider Voyager 1 is something like 20 billion kilometers away and its signal strength by the time it reaches Earth is less than an attowatt! (a billion billionth of a watt)

[AcreartStudio]

Your channel is interesting! super cool!😍

[hammerhead__]

Great video, thank you!!
Your channel is awesome

[johnnycruz]

this is the coolest thing I've ever seen

[tenesto]

How is it the other way? If u need so much technic to receive from space, how do spacecraft receive there signal?

[JohnJones-xjjs]

Let's show the love for each other and never give up on each other or are would or I kids much love 💝😘

[tiemenfiat]

Wave guides are made for a limited frequency range. Are all spacecrafts using the same frequency? And, when the speed increases of which earth and the spacecraft get separated, the wavelength changes due to the doppler effect. How does that influence the receiver setup?

[artfox]

Impressive, if you could answer one question please, we know that this type of communication is very limited in term of bandwidth, so how they can receive a 4k video from spacecraft, and how much time in general do they take to be transmitted?
The biggest question is how they've been able to do live streaming, with clear voice and video from the Apollo missions to the moon 50 years ago?
