Aligning the Primary Mirror Segments of the James Webb Space Telescope

James Webb Space Telescope (JWST)
Published on Sep 21, 2017

Engineers at NASA’s Johnson Space Center in Houston used light waves to align the James Webb Space Telescope’s mirror segments to each other, so they act like a single, monolithic mirror in the cryogenic cold of the center’s iconic Chamber A.

Part of the Webb telescope’s ongoing cryogenic testing in Chamber A at Johnson includes aligning, or “phasing,” the telescope’s 18 hexagonally shaped primary mirror segments so they function as a single 6.5-meter mirror. All of these segments must have the correct position and correct curvature; otherwise, the telescope will not be able to accurately focus on its celestial targets.

Any news on the latest configuration ?

More details being revealed at ADEX/Seoul Air Show would be a good bet. Apparently both the F-22 and F-35 have flight demos so there's no way I'm not going.

I think overall I would have been happier had they build two new amphibs like the Navantia Juan Carlos I/Canberra design or even (if it was unavoidable to keep BAE Systems in the game) a home-grown LHA design. Trying to get back into the flattop game probably sounded good in the late 90s when even second-tier nations like Brazil and India were furthering their ambitions with second-hand kit but I doubt anyone in the MOD really sit down and analyse how useful the Illustrious Class was compared to how much a drain the strike carrier fleet was on manpower, escorts and resources even in the 1950s and 60s.

Manpower and money are key. There's no point politicians pointing at shiny new toys when they're tied up with nobody to man them and no fuel to put in them.
Still, how many other navies are in a similar situation.

One piece of slightly better news, RAF Saxa Vord on the Shetlands will re-open to increase radar coverage to the north.

Very interesting video indeed !
At 2:54 the Hormone is awaited by soldiers with their weapons at the ready. Just in case, the crew turns
out not to be, what they were expected to be ? Is this standard practice in other navies, too ?
