No one. It was the first Earth satellite and sent in space by the the Russians (USSR).
One example of a man-made Indian satellite is "Aryabhata," which was India's first satellite launched in 1975.
The Hubble Space Telescope is one of the most famous satellites in space. It has provided stunning images of distant galaxies and has helped scientists in making groundbreaking discoveries about the universe.
One invention is the Jupiter-C rocket, which carried the first US satellite into space.
The first artificial satellite, was the Russian Sputnik. It weighed 184 pounds. The first American satellite weighed only 1.8 pounds. The Russian's second satellite weighed about one ton.
India has launched several satellites into space, with one of the most notable being the Indian National Satellite System (INSAT). Additionally, the Indian Space Research Organisation (ISRO) has developed the Indian Remote Sensing (IRS) satellites. Another significant satellite is the Mars Orbiter Mission, also known as Mangalyaan, which made India the first Asian nation to reach Martian orbit.
One major difference between an artificial satellite and a space probe is that an artificial satellite typically orbits a celestial body, such as Earth, while a space probe is designed to travel through space to explore other celestial bodies.
The first satellite was launched into space by the Russians on the 4th of October 1957. Its name was Sputnik, but it was later called Sputnik I so they could distinguish it from the other satellites that they would launch into space at a later time with the same name.
A satellite is one object orbiting another, so the moon is a satellite of Earth. A man made satellite is one we have launched in to orbit. The first being Sputnik, launched by the Russians, to thousands orbiting now providing communications for us in this modern era along with entertainment and GPS.
The technology developed in the 1950-1990's we use today. Your cell phone technology was first made in 1971 and the satellite TV dates from the first one in 1957. It is the same with GPS and even the computer technology grew out of the space program.
As far as was publicly announced, the first artificial satellite successfully placed into earth orbit ... the first one that stayed up long enough to actually make some orbits around the earth ... was the "Sputnik-I", launched in October of 1957 from the USSR (Russia).
Explorer One launched on January 31st 1958.
