LADINEK: p-o-r-n-o!!

Jedna hodne dobra animace, jestli uz bylo tak se omlouvam :)

Am thinking of starting new university:
Texas Institute of Technology & Science

motorová sekce B4 dostává kryty

BLACKHEAD: na 2022 je naplanovano 6 misi falcon heavy, takze to bude docela fofr:

SEJDA: taky je otáka, jestli se po návratu skrz atmosféru to plexisklo vrátilo v nějakém vícenásobně použitelném stavu :-)

XCHAOS: Pri letu do vzdalenosti milionu kiometru bude IMHO Zeme porad videt jako dost velka koule, podobne jako tady na Zemi vidime Mesic. Akorat bud vidime Mesic, nebo Slunce, pripadne oboje, podle kalendare. Kdezto ze vzdalenosti milionu kilometru uvidis Zemi i Slunce porad. Jen Mesic se ti nekdy muze schovat za Zemi, v zavislosti na tom, kde presne jsi v prostoru kolem Zeme.

I pri ceste na Mars uvidis Zemi porad, pokud uz ji teda nebudes mit schovanou za Marsem, Sluncem, nebo pokud ji nebudes mit moc blizko u Slunce, tedy pokud bude na stejne strane Slunce jako "ty", pozorovatel v rakete...

Zeme je vetsi nez Mars. A tak jako pouhym okem vidis oranzovou tecku ze Zeme, tak z Marsu uvidis modrej puntik.
A tedy po ceste se bude postupne zmensovat, az do te velikosti puntiku, porad ale vetsiho nez Mars odsud.

Navic uvidis o neco vetsi Jupiter. ;-)
A ano Slunce bude mensi.
Marsovi vlastni mesice asi nijak vyrazneji videt nebudou (tecky na nocni obloze), ten vetsi Phobos ma jen kolem 22km a lita cca 9500 km daleko. Ve srovnani s nasim Mesicem je to jen kus sutru. Tipuju, ze videt bude asi neco jako Mars ze Zeme.

Ale docela posvisti kolem (narozdil od Deimosu), Phobos preleti celou viditelnou oblohu oblohu asi za tri hodiny.

SpaceX’s Bill Gerst says Crew Dragon’s toilet mechanics were redesigned after the toilet issues on the Inspiration4 mission. A tube that sends urine into a container broke off during the mission and leaked into a fan which sprayed the urine in an area beneath the capsule floor.

Gerst says the crew didn’t notice anything during flight; it only affected the internal section under the floor. Redesign involves a fully welded system with no joints that could come “unglued” like the faulty Inspiration4 system did.

SpaceX, concerned that the same toilet issues are plaguing its other vehicles, had astronauts use a borescope to investigate the Crew Dragon currently docked to the ISS. They confirmed SpaceX’s suspicions and indeed found similar contamination under the floor, Gerst said

Astronaut pee is mixed with a compound called Oxon, and SpaceX worried that might corrode hardware on Crew Dragon if pools around the system unchecked for months. So SpaceX did "extensive tests" on the ground that involved soaking aluminum parts in an Oxon-pee mixture

For "an extended period of time," the Oxon-pee-soaked aluminum parts were placed in a chamber that mimicked the humidity conditions on the ISS. SpaceX found "that corrosion growth" caused by Oxon pee "limits itself in the low-humidity environment onboard station."

So anyway, Crew Dragon appears to be resilient to piss. Gerst: "Luckily, or, on purpose, we chose an aluminum alloy that is very insensitive to corrosion." The study is ongoing — "We got a couple more samples we'll pull out of the chamber"
This was a really good example of how a engineering problem was detected, studied and fixed. Gotta commend Gerst’s transparency here.
