NASA: Second Flight Instrument Delivered for James Webb Space Telescope:
The second of four main instruments to fly aboard NASA's James Webb Space Telescope (Webb) has been delivered to NASA. The Fine Guidance Sensor (FGS) will enable the telescope to accurately and precisely point at the correct, intended objects for it to observe. The FGS is packaged together as a single unit with the Near-Infrared Imager and Slitless Spectrograph (NIRISS) science instrument.

Can someone explain, why the reflection in the mirror in the second picture is not inverted?Perspective looks correct though. First guess would be its geometry, but the first image was taken from a similar angle and yet that one look normal. Seems a bit weird, doesn't it?

In the second picture, the camera was beyond the mirror's focal point, thus the inverted image.

NASA: Blanketing NASA's Webb Telescope's Science Instrument Electronics

693301main_blanket-webb-670.jpg

Engineers Josh Lutter (on the right), Bruce Haines (center) and Scott Lam (on the left) tuck layers of blanketing in-between the gold-colored louvers on the James Webb Space Telescope's Integrated Science Instrument Module (ISIM) Electronics Compartment (IEC) at NASA’s Goddard Space Flight Center in Greenbelt, Md. The blanketing insulates and shields the flight instruments and the louvers will keep heat away from the temperature-sensitive instruments that will peer through dust clouds to see how stars form.​

You're looking at the eye that will see into creation itself. Big telescopes are sexy and romantic - this JWST rig is no exception.
