I have two steadfast rules:
I would never buy an American motorcycle.
Will never buy a Japanese car.
Most American r/c engines are junk too.

I consider Hardly-Movingsen MORON-Cycles as over priced, heavy, CRAPPY sounding, under-powered junk.

I'd love to see the pics!

Good!

This first photo is of the "clean room" where the JWST was assembled.

Obviously the JWST is no longer here, but these banners and posters show the composition. I didn't know until my visit to Goddard that the JWST is NOT enclosed (like the Hubble is.) one of the many things I don't know about it is: where are the solar panels? I should have asked.

The honeycomb array of 18 gold mirrors unfolds after the telescope is placed in orbit. I'm assuming the software compensates for the color of the mirrors(?)

Here's an interesting item! It's a VERY LARGE environmental simulation chamber. The spacecrafts are placed into it and it simulates all possible conditions of space--except for zero gravity.

Here's an item that will actually go to space: a satellite buss. If I understood my host correctly it's what holds the spacecraft in the fairing atop the rocket.

Last photo (I'm sorry there aren't any more!) This the acoustic chamber. The large tunnels at the top and bottom are bass "cannons" that pound the spacecraft in the chamber to simulate the shock and vibration of launch.

Also, I was wrong about the centrifuge at Goddard: it’s NOT for spinning astronauts, it’s just for spinning flight hardware.
