SEJDA: moderatori by mohli mit aspon zakladni prehled a kdyz ne ten, tak aspon slusnost, ale chapu, ze silnym nazorem muskoliku zadna fakta nemuzou pohnout

SEJDA: SEJDA: GoPro kde?

"Jak te presne napadlo srovnavat takovyto cip..."

Ne, ja nesrovnaval vlastnosti kameroveho systemu na Blue Ghost s temi teleskopy, ty jsou prikladem mereni - snimku priznane filtrovanych / upravenych bezpecnostnimi slozkami. Bylo to prilis slozite souveti?

NASA Cameras to Capture Interaction Between Blue Ghost, Moon’s Surface - NASA
https://www.nasa.gov/general/nasa-cameras-to-capture-interaction-between-blue-ghost-moons-surface/
"Developed at NASA’s Langley Research Center in Hampton, Virginia, Stereo Cameras for Lunar Plume-Surface Studies (SCALPSS) is an array of cameras placed around the base of a lunar lander to collect imagery during and after descent. Using a technique called stereo photogrammetry, researchers at Langley will use the overlapping images from the version of SCALPSS on Nova-C — SCALPSS 1.0 — to produce a 3D view of the surface.
...
SCALPSS 1.1, which will feature two additional cameras, is scheduled to fly on another CLPS delivery — Firefly Aerospace’s Blue Ghost — later this year. The extra cameras are optimized to take images at a higher altitude, prior to the expected onset of plume-surface interaction, and provide a more accurate before-and-after comparison."

SEJDA: Pripadam si jako nekdo, kdo cetl specifikaci Blue ghost a nevyklada o nem nesmysly, zna detailne rozdil mezi metodou a pristrojem, a nikdy nepodporoval Elona Muska. Co ty? Kdy jsi naposled urcoval nejistotu mereni u optiky?

VOYTEX: Nepripadas si jako idiot, kdyz srovnavas vedecke instituce a mega teleskopy s GoPro kamerou?

SEJDA: Mozna to neni patrne, ale u vedeckych expedic, kde se provadi mereni, byva dobrym zvykem cely neupraveny zaznam (stahli 57 GB) doprovodit parametry pristroje a hlavne ho neupravovat, pripadne upravu, jako je ztratova komprese, odstraneni klasifikovanych objektu jako na teleskopech PanStarrs, Sofia nebo Vera Rubin, atd, nejak anotovat.

Za "buzeni pocitu" si odpovida kazdy sam.

KAERO: To je moc zajimavy.

Z polovojenskeho Apolla 11 pred pul stoletim byl zivy prenos (ackoliv NASA odmitla novinarum napojit primy videovystup, smeli jen natacet projekcni platno), stovky fotek formatu 6x6 na optimalne osviceny diapozitivni kinofilm, ekvivalent minimalne 100 Mpix kazda a 16 mm filmy, cca 2k rozliseni.

Civilni Firefly zverejnili jeden timelapse z 15 minut, s dvoudennim odstupem 2 sestrihane minuty pristani, a nekolik mobilovek s 6 Mpix. Zive video pristani na privracenou stranu Mesice (ping ~ 2 sekundy) nebylo pry kvuli nedostatku sirky pasma pro telemetrii.

Me by zajimalo, jake je mistni povedomi o obvyklem poctu a parametrech transponderu srovnatelne velkych sond / druzic jako pultunovy Blue ghost.
