I hope I am still alive by the time this thing actually launches.

I remember looking forward to this launching since I was a young teen. I'm in my 30s now. I can't believe I still have to wait another 2 years until launch.

[dallastaylor]

So looking forward to this launch. To all those who worked this, their meticulous efforts and their dedication, I say THANK YOU! You are appreciated. You make the stuff dreams are made of❤

Really good video. I probably would have replaced the line about SPF 1Million with a line about how the internal components must be kept colder than the space around it.

Goose bums already at the thought of the magnificent pictures Webb will

This is IF Northrop Grumman can actually get the thing built and it all works during launch. I hope they don't use the same payload adapter they used for the ZUMA mission.

Blows my mind that JWT isn’t more of a national news story. Instead we’re bombarded with negative meaningless programming. If successful, it’ll be the greatest instrument ever created by humans. It reminds me how amazing humans really are. All are invited to my launch party.

I hope they stop delaying it. I’m over these delays

[vanleeuwenlevi]

I am very excited for this mission! Can't wait.

[stantonsasaki]

I can’t wait to see the images! Thank you science community!

[parcito]

Can't wait to see what will come with, once Webb has established on orbit!

[adishaswot]

What an incredible piece of human work!

Great project! Can't wait to see what this will show us

I am happy for my grand grand daughter/son will be watching the launch.

Launch Date announced on June 27 2018 is March 30 2021 in the NASA video titled: "Administrator Bridenstine: NASA is Committed to Webb Telescope".

Why did they cut the launch date voice off ?

[andriesv]

It is the best, it is the largest, it is the golden telescope. Ok we got that. But when " It is in space!! " :)

When the Hubble mirror was found to be flawed, a mission was send up, to correct the error. James Webb telescope looks like it breaks just by looking at it. How will repairs or maintenance be achieved here?

[venkyv]

Awesome video. So inspiring and insightful. Hope this mission will shed more light into human existence and our place in this jigsaw
