Sputnik 1 (/ˈspʌtnɪk, ˈspʊtnɪk/, ‹See Tfd›Russian: Спутник-1, Satellite 1) was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries became depleted. Aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. The world’s first observation was made at the school observatory in Rodewisch (Saxony).
It was a polished metal sphere 58 cm (23 in) in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth.
The satellite’s success was unanticipated by the United States. This precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. The launch was the beginning of a new era of political, military, technological, and scientific developments. The word sputnik is Russian for satellite when interpreted in an astronomical context; its other meanings are spouse or traveling companion.
Tracking and studying Sputnik 1 from Earth provided scientists with valuable information. The density of the upper atmosphere could be deduced from its drag on the orbit, and the propagation of its radio signals gave data about the ionosphere.
Sputnik 1 was launched during the International Geophysical Year from Site No.1/5, at the 5th Tyuratam range, in Kazakh SSR (now known as the Baikonur Cosmodrome). The satellite traveled at a peak speed of about 8 km/s (18,000 mph), taking 96.20 minutes to complete each orbit. It transmitted on 20.005 and 40.002 MHz, which were monitored by radio operators throughout the world. The signals continued for 22 days until the transmitter batteries depleted on 26 October 1957. On 4 January 1958, after three months in orbit, Sputnik 1 burned up while reentering Earth’s atmosphere, having completed 1,440 orbits of the Earth, and travelling a distance of approximately 70,000,000 km (43,000,000 mi).

After 90 minutes of trying to remove the mudguard from my old bike. I finally succeeded in removing the front wheel.
I’ve been uncharacteristically careful while dissembling but it looks like the brake/gear wires have to be cut for the bike to come apart.
@7bicycles any sage advice?
Holy fuck curry is amazing.
I thought it would take a long time to make and just be like a normal sauce but this took me 15 minutes and it’s the most flavorful thing I’ve ever eaten. This and rice beats 99% of the meals I’ve ever eaten.
“Andor is the best Star Wars since Empire” mfers when they remember Empire’s dark, mature themes of Luke fighting a yeti, beating a tank by tying it’s legs with rope, and Han walking inside a space worm’s mouth.
i suddenly realized i misgendered a hexbear like three weeks ago

Down with cis!! Another megathread down!!!
People on twitter are acting pleasantly surprised that the Silent Hill 2 remake is getting good reviews as if its not blatant that every single creative decision made for the game is in service of review scores lol.
The most attempted crowd pleaser game design I’ve seen in a while.
Just took a bong rip after eating hot Cheetos and, y’all I have fucked up. My lungs are spicy
Inbwt Mario has said the N word at least once.
Noid?
Huh we don’t have a Noid emote.
Told my Partner about Hexbear and this owl that pisses and farts a lot.
I’m going to be honest, I did not expect Moby Dick to be a page turner
I don’t get the condescending attitude towards gen alpha’s adoption of AAVE like rizz or gyatt, but it irks me that it completely replaced local memes. There are no local (sub) cultures any more, just international standardized youth cultureTM.
my “Am I Racist?” movie is raising a lot of questions already answered by the movie
I will yap about serial webnovel trash now.
The latest chapter of What Little Remains of Terpsichore Ironheart just released and I was cackling all the way through it. This is the latest fiction from HorizonTheTransient, one of my favorite serial webnovel authors, whose signature thing is Extremely Horny Trans Lesbians Changing The World Through Materialist Analysis And Sufficient Application Of Firepower. Both worldbuilding and character writing are particular strengths.
The setup this time is that five hundred years ago humans genocided almost all the elves because both the humans and the humans’ actually existing gods are bigots. And because elves are biologically immortal, this is still in living memory for the remaining elves who now live in racialized ghettos in human cities, but not the humans. Our main character is a young elf man whose parents survived the genocide, and also an egg. The latter I claim because of the way he is and also from having read this author’s other fictions. This is also complicated by his defensiveness about being seen as feminine because elf men are bishounen so he reads any perception of femininity as anti-elf racism.
In those five hundred years the world has developed things like industry and magitek but our MC was raised on stories of heroic elven mage-knights riding now-absent unicorns and so has decided to tear down this world of human supremacy astride a sweet magitek motorcycle of his own manufacture.
It fucking rules, and you, yes you, the person reading this right now, should give it a try.
Goddamn that sounds kind of awesome.
It rules, read it
I mean… Perhaps. I have bookmarked it.This is peer pressure I am peer pressuring you
It sounds too high fantasy for my taste
It’s more modern fantasy than anything, but modern fantasy with materialist worldbuilding.
It has Elves, mages and unicorns it’s just not going to do much for me despite the worldbuilding.
When I got my covid vaccine yesterday, a couple drops of the vaccine dripped out of my arm when the pharmacist was administering it, I probably got enough for it to work though, right?
I’m nervous because last time it beat my ass the next day and this time I also got the flu shot and all I have is pain at the covid injection spot
