Sputnik 1 Launches: The Space Race Begins
Sputnik 1 was a polished aluminum sphere 58 centimeters in diameter, weighing 83.6 kilograms, with four radio antennas trailing behind it. Its steady beep, transmitted at 20.005 and 40.002 MHz, could be picked up by amateur radio operators worldwide. The Soviet launch on October 4, 1957, blindsided the American establishment. President Eisenhower tried to downplay it, but the public panicked. Congress poured billions into science education through the National Defense Education Act. NASA was created within a year. The satellite itself burned up on reentry after three months, but the psychological shockwave lasted decades. The space race it triggered consumed 4.4% of the federal budget at its peak and put humans on the Moon within 12 years of that first beep.
