James Webb Space Telescope Launch — Official NASA Broadcast


The launch date/time is Dec 22 at 7:20 a.m. EST

Watch live on NASA’s youtube channel

Watch the launch of the James Webb Space Telescope—the most powerful space telescope ever made. This mission is scheduled to lift off at 7:20 a.m. EST (12:20 UTC), Dec. 22, 2021, aboard an Ariane 5 rocket from Europe’s Spaceport in French Guiana.

With revolutionary technology, Webb will observe a part of space and time never seen before, providing a wealth of amazing views into an era when the very first stars and galaxies formed––over 13.5 billion years ago.

It can explore our own solar system’s residents with exquisite new detail and study the atmospheres of distant worlds. From new forming stars to devouring black holes, Webb will reveal all this and more! It’s the world’s largest and most powerful space telescope ever built.

Webb is an international collaboration between NASA, ESA (European Space Agency), and CSA (Canadian Space Agency). Thousands of engineers and hundreds of scientists worked to make Webb a reality, along with over 300 universities, organizations, and companies from 29 U.S. states and 14 countries!


I’m really looking forward to what it teases out of the cosmos. Really hope the launch goes well.


I subscribe to NASA’s channel and will try to update this post if there are any changes to the launch schedule.


A bit counterintuitive that Europe’s spaceport is in South America. :slightly_smiling_face:

thanks for the awesome information.

You bet! And welcome.

btw @alexsunny123 you might be interest in this program from the national cathedral on “Our Future in Space”

Europe is too far from the equator for efficient space launches. The site they’ve chosen (chosen by the French, originally) is close to ideal: near the equator, with open water to the east for debris to fall into.


With the close of our Space shuttle program, for a time American astronauts had to hitch a ride to the ISS on Soyuz rockets from Kazakhstan. Now we can blast off from American soil via Elon Musk’s Spacex spacecraft.

At face value, that Europe’s spaceport is in South America still has some incongruity to it, though. Maybe the fact just isn’t ingrained in me enough.

I just found this video from 60 minutes:

Looking back in time with the James Webb Space Telescope

Does a great job of explaining everything.

Enjoy free access to this NY Times article:
Why the World’s Astronomers Are Very, Very Anxious Right Now

What do astronomers eat for breakfast on the day that their $10 billion telescope launches into space? Their fingernails.


Just looking at the map, Kenya would also be a good place to launch rockets, but has it’s difficulties also. We have a spaceport in south Texas, but so far is just a glorified Six Flags ride.


Since the James Webb is going to allow us to look back in time 13.5 billion years ago, I’m sure Ken Ham will have something to say about this!

They always tell me that because the Bible says light was created before the sun and stars that means their light appears older than it is or some other weird nonsense.

For all we know, God could have created the world last Thursday and implanted us with false memories.

That’s good. It just made me significantly more righteous lol.


It may blow your mind to learn that the spaceport is in French Guiana which is a French territory and part of the EU. If you go to watch the launch and then go to a local restaurant afterwards you will be paying for your meal with Euros.

This is no surprise and in no way blows my mind. All I have said is that it is a bit counterintuitive [superficially and at first glance] that Europe’s space port should be in South America. Good grief.

The launch date/time has been revised:

It’s now December 24 at 6 am EST or 7:20 am EST. Not sure which time is correct; the NASA youtube channel lists both times. But an excellent Christmas present.
