47 free Sputnik 1 trivia questions with answers — history quiz, new questions added Oct 2026.
On 4 October 1957 a polished aluminium sphere the size of a beach ball began beeping its way around the Earth every 96 minutes, and the world changed. Sputnik 1 was thrown together in months because the Soviets feared America would get there first, it ran on batteries that lasted just three weeks, and it burned up after 1,440 orbits. Yet it triggered the Sputnik crisis, the creation of NASA and DARPA, a rush of science funding in American schools, and even the idea behind GPS. This quiz covers the whole story: Sergei Korolev's design bureau, the R-7 rocket and its failed test flights, the satellite's design and radio frequencies, the reaction in Washington and around the world, Sputnik 2 and the dog Laika, and where the surviving backups sit today. It is written for space fans, Cold War history readers and anyone brushing up on the dawn of the Space Age; early questions are approachable, later ones ask for engineers' names and exact figures. Every answer was checked against Wikipedia's articles on Sputnik 1, Sputnik 2 and the Sputnik crisis, and each question carries the sentence that supports it. Our Space Race quiz picks up where this one ends.

Q 01Which word did columnist Herb Caen coin six months after Sputnik 1, borrowing the satellite's ending?
Beatnik
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.
Q 02What was Sputnik 1's claim to fame?
First artificial Earth satellite
Sputnik 1 was the first artificial Earth satellite; its success in 1957 caught the United States off guard and set off the Space Race.
Q 03What does the Russian word 'sputnik' literally mean?
Fellow-traveller
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'.
Q 04Sputnik 1's plain round shape helped scientists measure what from the way its orbit decayed?
Upper-atmosphere density
Upper-atmosphere density: thin air slowed the satellite, and the rate at which its orbit shrank showed how much air was still up there.
Q 05What were Sputnik 1's four long spikes?
Radio antennas
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.
Q 06Sputnik 1 was about the size of what?
A beach ball
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.
Q 07Roughly how much did Sputnik 1 weigh?
About 84 kg
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.
Q 08What silenced Sputnik 1's signal after about three weeks in orbit?
Its batteries ran flat
Its batteries ran flat after 22 days; with no solar cells to recharge them, the satellite could only circle on in silence.
Q 09Roughly how long did Sputnik 1 take to circle the Earth once?
About 1.5 hours
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.
Q 10How did Sputnik 1's flight end in January 1958?
Burned up on re-entry
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.
Q 11Which Soviet chief designer led the programme that built and launched Sputnik 1?
Sergei Korolev
Sergei Korolev was named in public only as the 'Chief Designer'; his identity stayed a state secret until his death in 1966.
Q 12Which rocket, originally designed as an ICBM, launched Sputnik 1?
R-7
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.
Q 13Hurried into orbit ahead of the Americans, Sputnik 1 had the code name PS: what did the Russian initials stand for?
Simple satellite
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.
Q 21What did most people who "saw Sputnik" cross the night sky actually see?
Its spent rocket stage
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.
Q 22Which British observatory's giant new dish tracked Sputnik 1's launch rocket by radar?
Jodrell Bank
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.
Q 23Which citizen-science project had volunteer teams with telescopes ready to spot Sputnik 1?
Operation Moonwatch
Q 14The heavy science laboratory that Sputnik 1 was built to stand in for finally flew under what name?
Sputnik 3
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.
Q 15From which launch site did Sputnik 1 lift off?
Baikonur
Baikonur began as a secret range for testing intercontinental missiles, known to its builders as Tyuratam; the space launches came second.
Q 16In which present-day country was Sputnik 1 launched?
Kazakhstan
Kazakhstan was then a Soviet republic; since the Soviet Union broke up, Russia has had to lease the launch site from its neighbour.
Q 17How did Pravda first report Sputnik 1's launch?
In a few short paragraphs
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.
Q 18What gas filled the sealed interior of Sputnik 1?
Dry nitrogen
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.
Q 19Which discovery, missed by the first two Sputniks, did America's first satellite make in early 1958?
Earth's radiation belts
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.
Q 20Which science-fiction writer proposed relaying radio by satellite in 1945, twelve years before Sputnik 1 flew?
Arthur C. Clarke
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.
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.
Q 24Sputnik 1 flew weeks after the 100th birthday of which Russian visionary of spaceflight?
Konstantin Tsiolkovsky
Konstantin Tsiolkovsky was born on 17 September 1857; the engineers had hoped to launch on his centenary but missed it by seventeen days.
Q 25Which US research agency was created in February 1958 in direct response to Sputnik?
ARPA (later DARPA)
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.
Q 26Which 1958 law, passed in the wake of Sputnik, put federal money into science, maths and language teaching?
National Defense Education Act
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.
Q 27What was the first successful American satellite, launched on 31 January 1958?
Explorer 1
Explorer 1 came from Wernher von Braun's Army rocket team, whose shelved satellite plan won approval only after the Sputnik shock.
Q 28Which American satellite launch blew up on its pad in December 1957 and was dubbed 'Flopnik' by the press?
Vanguard TV-3
Vanguard TV-3 rose about a metre, fell back and exploded; its little satellite was thrown clear and found nearby, still transmitting.
Q 29How had President Eisenhower learned of Soviet rocket progress before Sputnik 1 flew?
U-2 spy plane photos and intercepts
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.
Q 30What was the name of the dog carried into orbit by Sputnik 2 on 3 November 1957?
Laika
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.
