Here at the Goddard Space Flight
Center in Greenbelt Maryland, we are building the most advanced
and largest space telescope ever constructed
the James Webb Space Telescope. With the big game right around the
corner, we thought, it'd be pretty cool to use a football to demonstrate
some of the testing we do here at Goddard to make sure that Webb is ready for
its mission. Launch is the most intense part
of any spacecraft's mission and we need to make sure Webb can survive
its ride on the very powerful Ariane V rocket.
Ben Lovera, 2016 Maryland High School Field
Goal leader will help us demonstrate.
Ben's kick imparts a force on the football
of slightly more than four Gs.
One G is the force you feel standing on Earth.
During launch, Webb telescope components can experience
forces up to 19 Gs or 19
times their weight. Imagine your legs holding up 19 times your
body weight - for humans, that's physically impossible.
Webb's composite structure and components
are built and tested to handle that. We put the Telescope, and
all of its components, through a series of tests to prove
that it can withstand the rigors of launch. These tests include:
vibration tests
music
centrifuge tests
and acoustic tests. We use this giant acoustic chamber
and its very powerful sound system to mimic the sound pressure and
frequencies we see on the Ariane V rocket during launch.

music
Sound pressure waves can cause vibrations
which may be very damaging. We test in this chamber
to make sure the rocket noise won't break anything.
We test every material used to build Webb
to make sure it can withstand the stresses of launch and properly function
in space.

Webb's instruments are designed to detect infrared
light from the farthest objects in the Universe. Our eyes can't detect infrared
light, but we can feel it as heat. Here's the heat where my hand
warmed up this football and left a heat print on it.
To perform it's mission, Webb's instruments need to be
extremely cold - very near absolute zero
or minus 459 degrees Fahrenheit.
We don't want their own heat influencing the images so we test
everything cryogenically in large test chambers.
And make sure everything works as it should in the freezing environment of space.
Materials can change dramatically
at these cryogenic temperatures. Not always how you'd expect.
Let's see what happens to this football in Liquid Nitrogen, which is still
about 70 to 100 degree warmer than some of Webb's instruments.
The ball's inner rubber bladder shattered
at this temperature but, wow, the outer shell holds
together! Webb's instruments on the other hand are built to
withstand such extreme temperatures. Not the sledgehammer
by the way! Test, test and test
again is the key. We'd rather have something break during
a test on the ground where we can understand the problem and fix it, than
in space. Soon the Telescope will be heading to Johnson Space Center
in Houston Texas for some more testing before it heads to
to Northrop Grumman in California to be assembled and packed into a rocket.
The Telescope will be launched from French Guiana in 2018.
This football may not be space worthy, but
it sure works well here on Earth! Check out

incredible mission that is the follow-on to the Hubble Space Telescope.

Excuse me, have you seen a Wizard?
Hey I was just asking, no need to be so aggressive!
What about you big fella, saw the old fart?
Ignorance everywhere!
Sorry to interrupt your chat guys but I'm raging!
So you think you can dance eh?
Well dance to this!
I wonder if this guy is a **** too.
Please help me!
What the hell happened to your hand?
What I do with my hand is none of your damn business!
How am I supposed to help you then imbecile?!
Okay, a few details aside, I was playing Truth or Dare with a demon and well... my hand went
somewhere it shouldn't have.
Ugh I can smell demon on you from a mile off.
There's only one way to remove that stench.
Chop it off!
No, I can't!
Lefty is my favourite!
Wrong answer!
Aaaaaahhh!!!
What am I supposed to do now!
Don't you know how hard it is with my right!
Only amateurs need hands.
What the hell is this?
This looks like it could do a lot of damage in the right places.
What's all the fuss here eh?
You think you can steal from me huh?!
No, no, I was just checking how big your pockets were I swear!
And what are you looking at baldy?!
Hey watch your manners Missy.
I'm very sensitive about my appearance!
Look, I can trade this really shiny coin for my life.
Hey, that's also mine!
Damn, can't catch a break...
Get out of here you filthy thief!
Run away!
Can you believe the filth I have to deal with?
Being a woman in a game is just disgraceful.
Being a bald space marine dressed as a knight is not great either but whatever.
So, what brings you here?
Not planning on stealing from me are you?
I may be a murderer and a scum-bag but I draw the line at being called a thief.
Just stay out of my way.
This place wasn't meant for the likes of you.
Yes because I fit right at home in a flowery meadow.
And what the hell are you looking at!
I've just been insulted with a baldy comment I'm in no mood for you!
(Spit) Scum!
What the hell now, can't I get peace for 5 minutes!
Boom!
You know where I've been?
The gym that's where, check out these muscles!
I'd rather not, I'm not into dudes.
You will be defeated by shear sexiness!
Check me out!
Jesus, I'm gonna enjoy putting you down.
And don't get any ideas that wasn't meant to sound dirty!
It's too late, I can already sense how much you dig me!
Enough of this nonsense!
That's a big shield, overcompensating for something?
More like undercompensating!
I'm big all over!
I need to get this boss fight over.
I can't take this anymore.
If you lay off those goat burgers maybe you'd gain at least 10% of my bountiful physique!
I bench press demon's 4 times my size.
God I love the intensity, especially around my crotch, check out those muscles!
Right, enough of this.
I'm too heterosexual for your shenanigans!
I shall return, harder, better, faster, stronger!
I shall get my puke bag ready for that day.
Tune in to Episode 3 or I'll show you his crotch!

Draw with me 4 | New Beginnings - Duration: 5:10.
Hi guys, it's me. I'm finally back
I know it's been so long since I last uploaded a video
Oh God... so many things have happened in my personal life that have affected my channel
and my other social medias... but, oh well...
I am going to work on this and do my best to upload regularly
Well, as you can see I am in a new location. That's one of the things that have happened, that I moved
and it's been a mess. And , as you can tell, it has affected my channel
So, well... what are we going to do today?
I am just going to keep with the basic 'Irene style' of videos
in which I just draw a little bit and I just show you the process behind my drawings
Since I moved, I've been trying to decorate my flat with personalised drawings and all that
So, I think that I want to do that. I want to draw something that I would want to hang on my wall
that is i the same style of my previous drawings. Which you can check on my Instagram account
In which I've upload a think a few of the drawings I am going to hang on my wall
So, let's do that! Let's do a drawing that you can be proud of and show it to your friends
when they come by to your house
Let's start!
So guys, what I've been doing recently is picturing the drawing on my mind before I do it
and decide which style and materials I want to go for
because I've really been playing around with materials and techniques
and one great artist that inspires my drawings recently is Isabelle Arsenault
I got this book because it was recommended by another one of my favourite artists, Frannerd
And since then, I've been mesmerised by Isabella and all of her magical textures that she applies in her drawings
they are just breathtaking
I am going to change and start using this 9B, graphite pencil
which is going to creaet really dark and blendable textures
which are going to enrich the whole drawing
when you work with really bendable pencils like this one
one thing that you start noticing is that, as you draw, you are smudging the drawing and all the textures you created
So, what I've learnt... or the best solution for this, is to put a small piece of paper
or wax paper... anything that you could have around your house
and put it under your hand. So, in this way, you are not smudging the drawing
