The James Webb Space Telescope is impressive.
It's three stories tall, as wide as a tennis court.
It's got a 21 foot primary mirror
and then it's got these 4 instruments that are just incredibly powerful.
It's the largest, most technologically challenging space telescope ever created.
It's one hundred times more powerful than the Hubble Space Telescope
but at half the weight.
It's designed to look back in time even further than Hubble
to see the very first galaxies to form after the Big Bang.
Building Webb is truly a feat of innovative engineering
each material must survive the turmoil of a launch and the
varying temperatures of space - and it all starts with
the elements.
