Sputnik 1 was successfully launched by the Soviet Union on October 4, 1957, becoming the first artificial object to reach Earth orbit. Having been launched during the Cold War era, this tiny, beeping, ball-shaped satellite caused great concern among many paranoid red-scared Americans for whom the event was not so much a great moment of scientific achievement, but rather a disconcerting development in the Soviet-American balance of power, which effectively put the Soviets thoroughly ahead of the U.S. in the so-called “space race”.
It looks like we can add "survivor of mass extinction" to the list of awesomeness associated with pronghorns. According to this piece on the BBC website, while mastodons, giant sloths, and camels were dying off like a bunch of evolutionary wimps 11,000 years ago, the pronghorn kept bounding along the American plains and deserts like a happy-go-lucky little smart-ass.
Cheetahs are cool. They're sleek. They're majestic. They’re hunters who use their speed to chase down their prey. They’re the fastest land animals around, topping out in some measures at 60-70 mph. The pronghorn is not as fast as the cheetah. To the lay person, a pronghorn looks like any other hoofed antelope-type creature — brownish, white, kinda boring. For the most part, it looks like a goat with aspirations. Despite having been clocked at 50-60 mph in full sprint — just a tad slower than the cheetah — the pronghorn is not nearly as cool.
