What is the name of a famous satellite?
First Earth satellite: Sputnik (1957)
Sputnik, more officially known as Sputnik 1, was the first artificial satellite to safely make it into Earth orbit.
Which is the first satellite in the world?
Description. The Sputnik 1 spacecraft was the first artificial satellite successfully placed in orbit around the Earth and was launched from Baikonur Cosmodrome at Tyuratam (370 km southwest of the small town of Baikonur) in Kazakhstan, then part of the former Soviet Union.
Do satellites fall back to Earth?
Even when satellites are thousands of miles away, Earth's gravity still tugs on them. Gravity—combined with the satellite's momentum from its launch into space—cause the satellite to go into orbit above Earth, instead of falling back down to the ground.
Who is the first satellite of ISRO?
The Aryabhata spacecraft, named after the famous Indian astronomer, was India's first satellite; it was completely designed and fabricated in India and launched by a Soviet Kosmos-3M rocket from Kapustin Yar on April 19, 1975.

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. Artificial satellites are human-made objects deliberately placed in orbit.

India has launched 342 satellites for 36 different countries as of 28 February 2021. As of 2019, the Indian Space Research Organisation, India's government space agency, is the only launch-capable agency in India, and launches all research and commercial projects.
What are the 2 main types of satellites?
There are two different types of satellites – natural and man-made. Examples of natural satellites are the Earth and Moon. The Earth rotates around the Sun and the Moon rotates around the Earth. A man-made satellite is a machine that is launched into space and orbits around a body in space.
Who was the first man in space?
On April 12, 1961, aboard the spacecraft Vostok 1, Soviet cosmonaut Yuri Alekseyevich Gagarin becomes the first human being to travel into space.
Who invented satellite in India?
The Indian satellite programme began in the 1970s after the success of Indian Space Research Organisation's (ISRO) success of the Rohini rocket programme in the 1960s. Reportedly, Vikram Sarabhai, the ISRO's founder appointed a team of scientists and engineers led by space scientist Dr UR Rao to develop the satellite.
