Let me get this right....

NASA (with a little bit of help from the nice folk at ESA) are planning to put a 6 1/2 tonne contraption on top of a heavy life Arianne 5 rocket. Then, they'll light the blue touch paper and retire, so that said contraption with its nano-precision optics experiences upto 10G while blasting off, in an effort to get to this pseudo-mythical "Lagrangian 2" point in deep space. L2 is so far away that no shuttle can reach it, indeed, anything can happen before you even get there.

However, if you do reach this point roughly 1.5 million kms from the Earth, that's when the fun starts. The solar panels have to deploy. This I surmise then gives the contraption spacecraft enough power to open its sun-brolley (which incidentally is the size of about 4 tennis courts). After this various motors (or whatever) have to whizz, purr, whine such that a 6.5m beryllium primary mirror opens, perhaps to within micron-accuracy precision accuracy. All the while, the secondary snaps down into place like a flimsy picnic table, all for the bargain price of $10 billion probably by the time it all gets done.

And if you don’t believe any of this me, just look here.

(Oh, yeah, and did I mention this will find the first galaxies that ever formed over 12 billion years ago, directly observe planets actually in the very initial stages of being build around nearby stars, and general revolutionise astronomy, science and personkinds understanding of the majestic awe that is the Universe).
