NECROMAN: dzban, cimicky haj .. ale to sem fakt nepatri, bez se zeptat do [ O ----==== ASTRONOMIE ====---- O ]

NECROMAN: To asi v ramci Prahy nesezenes ne? I v clanku ti pisou "Je tedy třeba vyhledat místo s tmavou oblohou daleko od měst. To při současném uzavření společnosti bude nejsložitější,"

Praha je hodne svetelne znecistena (viz mapka Link na vetsi rozliseni):

Kdyby nekdo jako ja premyslel co presne tohle PER2 je, tak jsem to nasel tady:

Stacking is complete for the twin Space Launch System (SLS) solid rocket boosters for NASA’s Artemis I mission. Over several weeks, workers used one of five massive cranes to place 10 booster segments and nose assemblies on the mobile launcher inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. Engineers with Exploration Ground Systems placed the first segment on Nov. 21, 2020, and continued the process until the final nose assembly was placed on March 2. Prior to the arrival of the core stage, the team will finish installing electrical instrumentation and pyrotechnics, then test the systems on the boosters. When the SLS core stage arrives at Kennedy, technicians will transport it to the VAB, and then stack it on the mobile launcher between the two boosters. The SLS will be the most powerful rocket in the world, producing up to 8.8 million pounds of thrust during its Artemis I launch.

Artemis I will be an uncrewed test of the Orion spacecraft and SLS rocket as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA aims to land the first woman and the next man on the Moon and establish sustainable lunar exploration.

SUMAC: chapu, vzdy kdyz se ukaze, ze Cina neudela jeste nic originalniho, nebo ze jenom doplnila mozaiku aplikaci toho, co jini udelali pred 60-150 lety, prijde ukazka toho, ze Cina je uzasna, protoze tam panuje surovy kapitalizmus s prvky centralniho rizeni.
Ja si vazim Cinu za jine veci, ktere jsou ale tak obousecne, az z toho mrazi. Napriklad vlada vydala appku, kde muzes hlasit zatezovani zivotniho prostredi, ale je to jak pise CYBERWOLF, totalni vabank. Drtiva vetsina lidi nikdy nic nenahlasi, protoze maji strach, a ti co nahlasi to vetsinou delaji z duvodu hospodarske souteze, tedy za risk ocekavaji uplatu.
Podivejme se treba na uspech Tesly (USA), a toho jak rychle postavili svoji Gigafactory u Sanghaje a u Berlina. Mne to pripada +/- stejne slozite.

Jako ano, ale...

V Číně to buď strana chce a pak s razítkama není problém, nebo to nechce a pak jsou razítka tvůj nejmenší problém.
