47 Fun Facts About Sputnik 1

Which word did columnist Herb Caen coin six months after Sputnik 1, borrowing the satellite's ending?

Beatnik first appeared in Caen's San Francisco Chronicle column on 2 April 1958, pairing the Beat writers with the Russian suffix that Sputnik had just made famous.

What was Sputnik 1's claim to fame?

Sputnik 1 was the first artificial Earth satellite; its success in 1957 caught the United States off guard and set off the Space Race.

What does the Russian word 'sputnik' literally mean?

Fellow-traveller: s- (together) plus put' (way). It was just the ordinary Russian word for any satellite, so the name the world took for a brand only meant 'satellite'.

Sputnik 1's plain round shape helped scientists measure what from the way its orbit decayed?

Upper-atmosphere density: thin air slowed the satellite, and the rate at which its orbit shrank showed how much air was still up there.

What were Sputnik 1's four long spikes?

Radio antennas: the four spikes were spring-loaded to swing out as the satellite left its rocket and arranged so the signal held steady as it tumbled.

Sputnik 1 was about the size of what?

A beach ball, near enough: the sphere was 58 cm across. Its chief designer raged at the poor finish of a mock-up, saying the ball would one day be shown in museums.

Roughly how much did Sputnik 1 weigh?

About 84 kg: a stripped-down stand-in for the 1.3-tonne science laboratory the Soviets had meant to launch first, which was running late.

What silenced Sputnik 1's signal after about three weeks in orbit?

Its batteries ran flat after 22 days; with no solar cells to recharge them, the satellite could only circle on in silence.

Roughly how long did Sputnik 1 take to circle the Earth once?

About 1.5 hours: each lap took some 96 minutes at roughly 29,000 km/h, so Sputnik 1 crossed the sky about fifteen times a day.

How did Sputnik 1's flight end in January 1958?

Burned up on re-entry on 4 January 1958, having circled the Earth about 1,440 times in three months, more than two of them in silence.

Which Soviet chief designer led the programme that built and launched Sputnik 1?

Sergei Korolev was named in public only as the 'Chief Designer'; his identity stayed a state secret until his death in 1966.

Which rocket, originally designed as an ICBM, launched Sputnik 1?

The R-7 was built as the world's first intercontinental ballistic missile; its design lived on in the Vostok and Soyuz rockets that later carried cosmonauts.

Hurried into orbit ahead of the Americans, Sputnik 1 had the code name PS: what did the Russian initials stand for?

Simple satellite, 'prosteishiy sputnik' in Russian: a bare radio beacon built in months because the big science satellite planned to fly first was running late.

The heavy science laboratory that Sputnik 1 was built to stand in for finally flew under what name?

Sputnik 3 flew on 15 May 1958 as a 1.3-tonne orbiting laboratory; in 1957 its instruments were running late, so a bare radio beacon went first.

From which launch site did Sputnik 1 lift off?

Baikonur began as a secret range for testing intercontinental missiles, known to its builders as Tyuratam; the space launches came second.

In which present-day country was Sputnik 1 launched?

Kazakhstan was then a Soviet republic; since the Soviet Union broke up, Russia has had to lease the launch site from its neighbour.

How did Pravda first report Sputnik 1's launch?

In a few short paragraphs, part-way down page one: only a day later, once the Kremlin saw how the world had reacted, did the satellite fill almost the whole front page.

What gas filled the sealed interior of Sputnik 1?

Dry nitrogen at 1.3 atmospheres filled the sealed shell; a pressure switch would have changed the signal's rhythm if a leak or meteoroid puncture let it escape.

Which discovery, missed by the first two Sputniks, did America's first satellite make in early 1958?

Earth's radiation belts showed up on a Geiger counter built by James Van Allen, whose name they now carry; the Soviets, first into orbit, had failed to map them.

Which science-fiction writer proposed relaying radio by satellite in 1945, twelve years before Sputnik 1 flew?

Arthur C. Clarke described satellites in geostationary orbit relaying radio and television around the world in a 1945 magazine article; such a system was working two decades later.

What did most people who "saw Sputnik" cross the night sky actually see?

Its spent rocket stage, 26 metres long, trailed the satellite round the Earth and shone like a bright star; the little ball itself was at the very limit of naked-eye vision.

Which British observatory's giant new dish tracked Sputnik 1's launch rocket by radar?

Jodrell Bank's 76-metre dish was barely finished when Sputnik 1 flew; its team hurriedly fitted a radar set and caught an echo from the rocket about a week after lift-off.

Which citizen-science project had volunteer teams with telescopes ready to spot Sputnik 1?

Operation Moonwatch was set up by the Smithsonian in 1956 to spot the first artificial satellites, so its volunteers were already trained and waiting when a Soviet one appeared.

Sputnik 1 flew weeks after the 100th birthday of which Russian visionary of spaceflight?

Konstantin Tsiolkovsky was born on 17 September 1857; the engineers had hoped to launch on his centenary but missed it by seventeen days.

Which US research agency was created in February 1958 in direct response to Sputnik?

ARPA (later DARPA) was the Pentagon's answer to the Soviet lead in space; one of its offices later funded ARPANET, the network that grew into the internet.

Which 1958 law, passed in the wake of Sputnik, put federal money into science, maths and language teaching?

The National Defense Education Act offered student loans and money for science, maths and language teaching; it cleared the House only once grants had been swapped for loans.

What was the first successful American satellite, launched on 31 January 1958?

Explorer 1 came from Wernher von Braun's Army rocket team, whose shelved satellite plan won approval only after the Sputnik shock.

Which American satellite launch blew up on its pad in December 1957 and was dubbed 'Flopnik' by the press?

Vanguard TV-3 rose about a metre, fell back and exploded; its little satellite was thrown clear and found nearby, still transmitting.

How had President Eisenhower learned of Soviet rocket progress before Sputnik 1 flew?

U-2 spy plane photos and intercepts of Soviet test signals had forewarned him, one reason he met the launch calmly while much of the public took fright.

What was the name of the dog carried into orbit by Sputnik 2 on 3 November 1957?

Laika, a stray from the Moscow streets, rode Sputnik 2 on 3 November 1957 and died within hours from overheating; the craft had no way to return.

The 40th anniversary of the October Revolution fell on 7 November 1957; told to mark it with something bold, the engineers had under a month to build Sputnik 2.

Two Johns Hopkins physicists tracked Sputnik by what property of its signal?

The Doppler shift in the signal's pitch as the satellite passed overhead let William Guier and George Weiffenbach work out its orbit within hours.

Which satellite navigation system, a forerunner of GPS, grew out of tracking Sputnik?

TRANSIT, the Navy's satellite navigation system, first reached orbit in 1960 and let Polaris submarines fix their position; it was the direct forerunner of GPS.

Which US president declared 'This is our generation's Sputnik moment' in a State of the Union address?

The "missile gap" was the belief that the Soviets led in long-range missiles; John F. Kennedy campaigned on it in 1960, though it proved illusory: the lead was America's.

How was Sputnik 1 protected during launch?

A cone-shaped payload fairing covered the satellite during the climb and was thrown off in orbit; engineers were still rehearsing that release in the workshop weeks before launch.

Sputnik Planitia, a vast plain of ice named after the satellite, lies on which world?

Pluto's Sputnik Planitia forms half of its famous 'heart'; its ice slowly churns, wiping away craters so the plain looks freshly made.

What sound did listeners around the world famously pick up from Sputnik 1?

"Beep-beep-beep" tones were all it sent, on shortwave frequencies picked so that amateurs with ordinary sets could tune in and follow it.

Why was Sputnik 1's shell polished to a shine?

To reflect sunlight: the radio engineers feared their equipment would overheat, and a bright shell was also easier to pick out through a telescope.
