the Soviet Union
On October 4, 1957, the Soviet Union launched the earth’s first artificial satellite, Sputnik I. The successful launch came as a shock to experts and citizens in the United States, who had hoped that the United States would accomplish this scientific advancement first.
Who was the first satellite invented?
Sputnik
Fifty years ago, on October 4, 1957, the Soviet Union launched Sputnik, the first man-made satellite, shocking the American public and beginning the Space Age.
What happened to the first satellite Sputnik?
Sputnik 1 burned up on 4 January 1958 while reentering Earth’s atmosphere, after three months, 1,440 completed orbits of the Earth, and a distance travelled of about 7.0×107 km (4.3×107 mi).
What was Sputniks purpose?
The pressurized sphere made of aluminum alloy had five primary scientific objectives: Test the method of placing an artificial satellite into Earth orbit; provide information on the density of the atmosphere by calculating its lifetime in orbit; test radio and optical methods of orbital tracking; determine the effects …
Is Sputnik still in orbit?
And though it only blasted off some six months after the Soviet’s Sputnik satellite, Vanuguard 1 still remains in orbit — more than 60 years later. This makes Vanguard Earth’s longest-orbiting artificial satellite, as well as the oldest human-made object still in space.
Where is Sputnik 2 now?
A USSR-built engineering model of the R-7 Sputnik 8K71PS (Sputnik II) is located at the Kansas Cosmosphere and Space Center in Hutchinson, Kansas, USA.
How many dead satellites are in space?
3,000 dead satellites
There are more than 3,000 dead satellites and rocket stages currently floating in space, and up to 900,000 pieces of space junk ranging from 1 to 10 centimetres in size — all large enough to be a collision hazard and a potential cause for disruption to live missions.
Which country has the largest number of satellites?
the United States
Of the 3,372 active artificial satellites orbiting the Earth as of January 1, 2021, 1,897 belong to the United States. This is by far the largest number of any single country, with their nearest competitor, China, accounting for only 412.
When did China shoot down a satellite?
January 11, 2007
On January 11, 2007, China launched a ballistic missile from Xichang Space Launch Center. The payload was a kinetic kill vehicle (KKV) that collided with a non-operational Chinese weather satellite, the Fengyun-1C (FY-1C), at an altitude of 863 km (534 mi), completely destroying the satellite.
How did Sputnik change the world?
Sputnik made it possible to test satellite pressurisation, to study radio wave transmission and the density of the atmosphere, and allowed scientists to learn how to track objects in orbit. Sputnik 1 orbited Earth every 96 minutes, and the fact that it passed over the USA seven times a day worried many Americans.
Is anyone lost in space?
More videos on YouTube We’ve lost only 18 people in space—including 14 NASA astronauts—since humankind first took to strapping ourselves to rockets. That’s relatively low, considering our history of blasting folks into space without quite knowing what would happen.
Has a human died in space?
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. All seven crew members died, including Christa McAuliffe, a teacher from New Hampshire selected on a special NASA programme to bring civilians into space.

Sputnik 1, the first artificial satellite launched, was a 83.6-kg (184-pound) capsule.
Who was the first person to invent a satellite?
First Space Satellite. Sputnik and the Fiftieth Anniversary of Dawn of Space Age. The space age began with the October 4, 1957 launch of the first Russian space satellite. Other Sputnik satellites and the first US Explorer satellite soon followed. It will soon be the 50th anniversary of the dawn of the space age.
Where was the first recording of Sputnik 1 made?
The ‘beep, beep’ sound of the satellite can be heard each time it rounds the globe.” The first recording of Sputnik 1’s signal was made by RCA engineers near Riverhead, Long Island. They then drove the tape recording into Manhattan for broadcast to the public over NBC radio.
