Indian Space and Research Organization

This article is providing information about all satellites launched by ISRO and its space programs, Launch Vehicles, Satellites info and its use in space. Before start let’s have some briefs of ISRO.

What is ISRO?

ISRO is known as the Indian Space and Research Organization authorized under the Indian Government.

Vikram-Sarabhai

Indian Government had decided to dig in space and set up INCOSPAR (Indian National Committee for Space Research) in 1962 under the supervision of Dr. Vikram Sarabhai. INCOSPAR developed the first Indian launching station “Thumba Equatorial Rocket Launching Station” (TERLS) at Thiruvananthapuram, Kerala

On 15, August 1969 after eight years of INCOSPAR its stopped and New Space Agency outcome as the name of ISRO by Dr. Vikram Sarabhai at Bengaluru, ‎Karnataka.

What is the work of ISRO?

ISRO works for explore to space. They are developing technology of space launch vehicles, new satellites which orbit Earth, Moon, Mars and providing new unknown information which is helpful to a human being.

There are 5 different departments under which ISRO operations divided.

  • Vikram Sarabhai Space Center (VSSC), Thiruvananthapuram
  • ISRO Satellite Center (ISC), Bengaluru
  • Mr. Harikota Range (SHAR), Mr. Harikota
  • Space Investment Center (SAC), Ahmedabad
  • Physical Investigation Laboratory (PRL), Ahmedabad

Launching Sites of ISRO in India

Launching Station is a place from where launch space mission using space vehicles also can say Rocket.

There are main 2 sites for Launch programs.

SITE NAME
LOCATION
USE
Thumba Equatorial Rocket Launching Station Thiruvananthapuram This site is used for a Sounding Rocket also named Research Rockets
Satish Dhawan Space Centre Sriharikota Sriharikota site is the main launch station of India. All of the major satellite launch programs held from here

Use of Space Vehicle and its work

Specifically, launch vehicles are one type of transport utility using it Satellite can be set up on the Earth orbit.

There are various types of Rockets developed by ISRO. Every rocket developed for a separate purpose. It differentiates using its payloads, traveling distance.

There are main 4 parts in every space rocket.

  • Nose Cone
    • Nose Cone contains Payload system and Guidance System
      • Payload System is a Scientific Equipment, Satellite, or Cargo (In specific Rockets which use for ISS – International Space Station).
      • Guidance System means Computers, Communication Equipment, Radars, etc. using control and guide rocket while flight mode.
  • Rocket Body
    • Rocket Body is an outer body of vehicle utilities. Aluminum, Titanium, Nickel Alloy, etc. can be used for body build up because it needs to survive in high hitting atmosphere while flight.
  • Fins
    • Fins are used at the bottom which can help to stabilize the rocket during its flight.
  • Engine
    • The engine is the main part of every rocket. Boost Whole Rocket to Space Engine has to play a major role. The engine creates maximum thrust to push the rocket into the space using the fuel.

What is Satellite? Definition of Satellite

A Device or Technology which can be used for an orbit the Earth, Moon, Mars, Saturn for different kind of purposes like which Communication Satellite, Remote Sensing Satellite, Navigation Satellite, Geocentric Orbit type Satellites – LEO, MEO, HEO, Global Positioning System (GPS), Geostationary Satellites (GEOs), Drone Satellite, Ground Satellite.

Since First Satellite launched SputnikI (Russia) on October 4, 1957, approx 8378 total Satellites launched till 2020.

How many artificial satellites are launched by India since 1975?

There are around 120 artificial satellites launched since 1975 to till today by ISRO.

As an Indian, we are proud of ISRO because of its abnormal achievements in space.

We have an example of the success rate of PSLV with 95% in the world and ISRO provides commercial launch also for other countries at the cheapest price in the world.

How to launch a satellite?

Let’s see, here a demonstration of the process for a satellite launch to orbit or space.

What is Earth Orbit?

In simple words, An orbit is a place where satellites are traveling around the earth.

For Satellites majorly three orbits are exist.

  • LOW EARTH ORBIT (LEO)
    • Up to 2000 kilometers (100 to 1250 Miles) from earth surface considered as an LEO.
    • The Orbit speed of the satellite is 7.8 km/S.
    • International Space Station (ISS) is orbited in LEO.
  • MEDIUM EARTH ORBIT (MEO)
    • From 2000 Kilometers to 35000 Kilometers (around 22000 Miles) from sea level known as MEO. MEO also called intermediate circular orbit (ICO).
    • Most of Artificial Satellites orbited here. All general-purpose service satellites like, Communication, Education, Navigation, etc. A well-known example is GPS (GLOBAL POSITIONING SYSTEM).
    • The orbit time of the satellite is 12 Hours. It means after 12 hours satellite finish 1 round of earth.
    • The orbit speed is approx 15000 km/S.
  • GEOSYNCHRONOUS EARTH ORBIT (GEO)
    • Above Medium Earth Orbit is known as GEO. Geosynchronous Earth Orbit starts from 35000 kilometers to around 45000 kilometers (around 28500 Miles) from sea level.
    • GEO is a Geocentric Orbit.
    • The orbit speed is approx 11000 km/S and orbital time approx 24 hours.
