Information on Space Exploration Timelines

Through space investigation, people have taken in an extraordinary arrangement of the planets, stars, and different things in space. More than 5,000 spacecraft have been sent off into space to get data starting around 1957. The rockets from different nations, with astronauts on board, space tests, and satellites were sent.

Many famous scientists like Sir Isaac Newton and Galileo Galilei started exploring from Earth about space during the 16th century. Although, the very first space exploration from earth dates back to the 15th century. Now, let's directly dive into space timelines!

History of the Space Age

Let’s now have a look at the  history of space exploration and the timeline 

  • 1543 - Nicolaus Copernicus distributed found that the Earth and the planets orbited the Sun. 

  • 1609 - Galileo utilized the telescope to see the stars and planets. 

  • 1668 - Isaac Newton created the primary reflecting telescope. 

  • 1686 - Isaac Newton distributed the Mathematical Principles of Natural Philosophy.

  • January 2, 1959 - First spacecraft Lunar flyby achieved a heliocentric orbit.

  • April 12, 1961 - Humans entered space.

  • October 7, 1959 - Far side picture of the moon.


Astronauts go through a careful preparation program. They concentrate on math and science in study halls. They figure out how to work their spacecraft by utilizing PC-controlled test systems. These gadgets present space explorers with conditions that they will later insight into during real flights.  Astronauts likewise should work on their physical wellness. They make special trips on planes to become used to the sensation of weightlessness.



Race into Space

  • In the 1900s scientists created rockets that could travel quickly enough to get away from the power called gravity. Gravity is a power on Earth that pulls objects toward the centre of the planet. 

  • The improvement of strong rockets permitted the Soviet Union to send off the first artificial satellite on October 4, 1957.

  •  It was called Sputnik 1, and it orbited around Earth. On November 3, 1957, the Soviet Union sent a dog into space. 

  • On April 12, 1961, the Russian cosmonaut Yury Gagarin became the first human to circle Earth in space. In 1963 Valentina Tereshkova became the first lady in space.

  • The National Aeronautics and Space Administration (NASA) got responsibility for the U.S. exertion. The first U.S. satellite was sent off on January 31, 1958.

  • On May 5, 1961, space astronauts  Alan B. Shepard, Jr., turned into the main American to enter space. Shepard flew for just 15 minutes and didn't finish a circle around Earth. On February 20, 1962, John H. Glenn, Jr., finished three circles around Earth. 

  • On July 20, 1969, space traveller Neil Armstrong was the first human to stroll on the Moon.

  • In 1965 Space Science And Technology Centre was established in Thumba, Kerala in India.

  • In 1971 Satish Dhawan Space Centre was established in Andhra Pradesh, India.

  • Mangalyaan was launched by India on November 5, 2013.

  • Chandrayaan was launched by India on 22 October 2008.



Space Shuttles

Let’s gather more information about space shuttles

  • In 1981 the United States sent off Columbia, the main reusable spacecraft, called a space transport. The principal segment had wings and was known as the orbiter. Joined to the orbiter were rockets, gas tanks, and oxygen tanks. When their fuel was spent, the boosters fell into the sea, where they could be recovered. 

  • Astronaut Sally Ride turned into the main U.S. lady in space on June 18, 1983, in a shuttle named Challenger. 

  • On 24 April 1990, a shuttle named Discovery was sent off to space to deploy the Hubble telescope.

  • On September 20, 1993, the Indian Space Research Organisation (ISRO) launched the first indigenous space shuttle, The Polar Satellite Launch Vehicles (PSLV) and 

  • On April 18, 2001, the Indian Space Research Organisation (ISRO) also launched another space shuttle, the Geosynchronous Satellite Launch Vehicle (GSLV). 

  • On 18 December 2014 LVM3-X was launched.

  • On 5 June 2017 Mk III was launched.


In this article, we have learned about Space exploration, which is the discovery and exploration of celestial structures in outer space employing unmanned or manned space flight. The history of space exploration includes many notable events. From this article we also learned about some interesting space exploration facts and space timelines, We have also discussed space and launches made for space and also about the scientists exploring from Earth. In case of more doubts feel free to ask in the comments.

FAQs on Let’s Look into Space Exploration Timelines

1. What is a space station?

Space stations are spacecraft that stay in orbit for a long period. Researchers can go through days or even a long time at a station doing tests. The Soviet Union started sending off space stations in 1971, and the United States continued in 1973. In any case, these stations didn't remain in space long. The Soviet station Mir remained in orbit longer, from 1986 to 2001.

During the 1990s the United States and 15 different nations were ready to construct and work on an enormous space station together. The new task was known as the International Space Station (ISS). The get-together of the ISS started in 1998. The principal team began to live in the station in November 2000.

2. What are space probes?

Space probes are vehicles that convey scientific equipment yet no travellers. Some make one-way journeys into deep space. Probes are controlled from Earth by radio. They send back their discoveries the same way. In the late1950s the Soviet Union and the United States sent off their most memorable profound space tests. Probes, at last, arrived on the planets Mars and Venus and went by the planets Jupiter, Saturn, Uranus, and Neptune. They gathered data on the planets' climates, moons, and ring systems. In the mid-2000s, researchers sent a few new probes to investigate Mars and different planets and items in space.

3. What is space?

The zone above and around our planet where there is no air to breathe or to scatter light is known as space. Space is a vacuum.
