Mirror deployed all 108.5º!
Now latching in place.
Now latching in place.
Actually, it is totally deployed.The thing is actually in space and mostly deployed!

So L2 is on the Earth side that is opposite to the Sun. If you know the zodiac constellations, then it's the one 6 months before/after the current one, i.e., the one high in the south sky at around midnight. So currently that's the Gemini and Cancer constellations.Having a hard time finding out where in the sky JWT will be. Can anyone narrow it down to a constellation?

Me too, and it will be more exciting when the Americans will send a woman and a dark-skinned to the Moon within this wild decade, and possibly infinite when humans will walk on another planet. The 2020s decade is indeed the decade of transformation, the decade where numerous iconic rockets (Atlas V, Delta IV, Proton) will go extinct in favor of much better launch vehicles.Some people say spaceflight/space exploration became boring because nothing happens these days. JWST is just one of many projects that proves the exact opposite. Space exploration actually is as exciting as never before in human history. And one can follow it live at home on a computer. I was watching the broadcast of the deployment while I was doing my sports. It is simply amazing. Can't wait to see the first images... (and it inspires me to buy a telescope)
Yes, but inThis is in russian, but you will figure out the story. After sunshield deployment magnitude changed from 16 to 14.
