I can’t wait to see the images that come from this. Hubble has been amazing and that launched over 30 years ago. Even with the upgrades over the years, Webb should be a huge step forward.

Oops. Doncha just hate a sudden, unplanned release? Technicians were preparing to attach Webb to the launch vehicle adapter, which is used to integrate the observatory with the upper stage of the Ariane 5 rocket. A sudden, unplanned release of a clamp band – which secures Webb to the launch vehicle adapter – caused a vibration throughout the observatory.
Thomas Zurbuchen, NASA associate administrator for science . . . said that, because JWST is so close to launch, it did not have sensors that had been in place when it was transported to French Guiana to measure the effect of the clamp release on the spacecraft, leaving only calculations estimating the force imparted on it.

Comments after the second article are worth a read. : ) |

¿ya know I always wondered about the Spanish Grammar? ¿ why do they put an upside down question mark at the top of beginning of a question sentence and the right side one at the end? .so I got into a standards debate w/a grammarian .¿why don’t they put an elevated period at the beginning of a statement sentence and regular one at the end ? .Period . *
Plus us been holding my breath for 20 years waiting for the Webb launch

Another delay, high winds aloft.
At least till Christmas Day.

Plus us been holding my breath for 20 years waiting for the Webb launch Sentence structure in Latin based languages is so much more logical. In English we will describe the topic, then present the noun at the end of the sentence, requiring the sentence to often be repeated to clarify. In Spanish, italian, and most latin based languages correct sentence structure presents the topic first, then elaborates on it. The upside down question mark or exclamation point also points the listener in the right direction. |

↑ good point Lee Rockoonz ↓
someday Webb will send back images of a lot of metaphysical empty space o the wonder reminded of Parmendies Nothing moves All there really is Plank scale wigglies Roll on roll on boys Roll your life away O you roll so gneiss Roll those paradise

Once a mirror segment's final shape is corrected for any imaging effects due to cold temperatures, and polishing is complete, a thin coating of gold is applied. Gold improves the mirror's reflection of infrared light. . . Essentially, the mirrors are put inside a vacuum chamber and a small quantity of gold is vaporized and it deposits on the mirror. . . A thin layer of amorphous SiO2 (glass) is deposited on top of the gold to protect it from scratches in case of handling or if particles get on the surface and move around (the gold is pure and very soft).

fingers crossed,,,mostly
that all that precision unfolds smoothly.
That is the real accomplishment!
As to what the spectral data
records, and images reveals
or imagine
of what it all means –
what is the universe ?
and does it matter to us
Pascalian observers?
Plus
Will it top what the
European Herschel contraption
already accomplished?
-will be endless
Metaphysical experiments….

Gotta admit the audacious of Scanning the ends or beginnings of Scientific mathematical universe just as the LHC smashed it way into the most minutest space of planck & the amount of money to flex their geeky muscle while its hard to keep t.p. on the shelf it is a wonder! shup of fools indeed |

Plus us been holding my breath for 20 years waiting for the Webb launch  Sentence structure in Latin based languages is so much more logical. In English we will describe the topic, then present the noun at the end of the sentence, requiring the sentence to often be repeated to clarify. In Spanish, italian, and most latin based languages correct sentence structure presents the topic first, then elaborates on it. The upside down question mark or exclamation point also points the listener in the right direction. And in German, you throw Momma from the train her suitcase... plus you have the extra characters: umlauts and the "ess-zett" (the character that looks roughly like a capital beta, but stands in for a double s). I'm guessing that the leading question mark gives you an early indicator to use the questioning tone of voice, and it encases the entire question. For German, quotes at the beginning are dropped to comma/period level. Now one language that I found was incredibly logical in terms of grammar was Japanese -- until you start counting things, in which case you attach a syllable that indicates what type of thing you are counting (i.e small animals, large animals, round objects, flat object) to the actual number. And then there is having to learn three "alphabets" -- Kanji (the ideograms that are similar to Chinese), hiragana (a phonetic alphabet generally used for newer words, but can also replace Kanji characters) and katakana (the phonetic alphabet for imported words). Any given thing you are reading can potentially include all three. |

With all the gold and beryllium (not to mention aluminum, steel, etc.) used in Webb, we are returning a whole lot of stardust to space. Is that considered recycling.

Ah ya wake me from my slumbers stephan & make me log in on a hot spot Its limited -so I can’t be the regular post hord I am  Have done a shallow study of the French language compared to the German linguistics It explains a lot  Butte I won't go into one lengthy meandering thoughts Just leave ya ll w/ a MohsPoehm,,, |
