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).

I met a libertarian expat today!

White American guy who thinks raising the minimum wage is bad and that poverty is a choice because he was poor and made it through college without having to use social services at all!

He’s married to a local brown Guatemalan woman from a wealthy family. She treats him like shit. Throws knives at him when she doesn’t like the food he cooks, took off her engagement ring and threw it at his eye when she got mad, frequently hits him, calls him the r-slur and giggles like a child over it, and will forge checks in his name all the time. Has also sent messages to his family pretending to be him and saying he hates all of them.

He says she’s a sweet person deep down and loves her despite all of it. It turns out that despite their facade of the rugged individual, Libertarians are as submissive as you can get.

That got very quickly to the point I couldn't laugh at the guy.

Same. Like... damn. Even libertarians don't deserve spousal abuse.

about 80% chance that she's the first woman that let him have sex with her
