What Is A Satellite?

Satellites, also known as artificial satellites, are deliberately placed in orbit around celestial bodies. These man-made objects serve a wide range of purposes, including communication relay, weather forecasting, navigation, broadcasting, scientific research, and Earth observation. Satellites play a vital role in various fields, enabling us to gather valuable data and enhance our understanding of the world.

  • A satellite is an object in space that orbits or circles around a bigger thing. There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial (such as the International Space Station orbiting the Earth).
  • Since 1975, India has been successfully launching a varied range of satellites.
  • Indian Space Research Organization (ISRO), a State-run space agency of India, is responsible for designing, building, launching, and operating these satellites.

These foreign satellites have been deployed into space through India’s reliable and efficient launch vehicles. These satellite missions have fostered international collaborations and strengthened India’s reputation as a reliable partner in space exploration and satellite deployment. The successful launch of foreign satellites by India reflects the country’s technological advancements and its growing significance in the field of space research and exploration.

India’s First Satellite Name

Aryabhata, India’s inaugural satellite, was named in honor of the renowned Indian astronomer. It holds the distinction of being the country’s first entirely indigenous spacecraft, developed and manufactured within India’s borders. On April 19, 1975, Aryabhata was successfully launched into space using a Soviet Kosmos-3M rocket from the Kapustin Yar launch site. This historic achievement showcased India’s growing capabilities in space technology and marked a significant milestone in the nation’s space exploration endeavors.

Artificial Satellite of India

India’s voyage into space began with the launch of its inaugural satellite, Aryabhatta, in 1975. Since then, the country’s space exploration has traversed a remarkable journey of 47 years, witnessing the successful deployment of over 120 satellites. This expansive timeline encompasses significant milestones, technological advancements, and notable achievements that have propelled India’s presence in the global space arena.
