ISRO is an acronym for Indian Space Research Organization. It is an Indian space agency centered mainly in Bangalore, India.

It was founded on August 15, 1969 by the scientist Vikram Sarabhai and currently owned by the Government of India. It has an annual worth of 1.18 billion in USD dollars.

ISRO was initially named as INCOSPAR (Indian National Committee for Space Research) from the year, 1962 to 1969.

Aryabhata was its first satellite, which was launched by the USSR (Union of Soviet Socialist Republics), while Rohini was its first satellite, which was placed in orbit by SLV-3. SLV-3 (Satellite Launch Vehicle) is a launch vehicle made by India.

ISRO made India the first country to successfully send their Mars Orbiter into the Mars Orbit, at first attempt.

Before Mars Orbiter Mission, ISRO's first mission was Moon, where a lunar orbiter was sent named Chandrayaan-1.

Besides SLV-3, ISRO has developed the following more advanced launch vehicles:

  • ASLV: ASLV is a short form for Augmented Satellite Launch Vehicle. It was a solid propellant rocket with five stages. Though, it had the power to place a satellite of 150 kg into the Low Earth Orbit, it was decommissioned later as it did not proved to be much successful.
  • PSLV: PSLV is a short form for Polar Satellite Launch Vehicle. It has the capability to launch small as well as big satellites into the GTO ( geostationary transfer orbit) and Sun synchronous orbits respectively. It is termed as expendable launch system.
  • GSLV | & ||: GSLV is a short form for Geosynchronous Satellite Launch Vehicle. It is also an expendable launch system and one of the heaviest ISRO's launch vehicle capable of placing a payload of at most 5 tons.
  • LVM3 (earlier called GSLV |||): This launch vehicle is currently under development and it is expected that it will be the heaviest vehicle ISRO has ever built, which will be capable of lifting the mass of nearly 640 tons. It will reduce the dependency on foreign rockets for lifting heavy mass.

After the successful implementation of Aryabhata and Rohini, ISRO has launched several other satellite programs as well:

  • Indian National Satellite System (INSAT) Series: The satellite series is generated to meet the requirements of search-and-rescue, broadcasting, telecommunications and meteorology. It is said to be the largest communication system in the whole Asia-Pacific Region.
  • Indian Remote Sensing satellites (IRS) Series: The series is developed keeping in mind the need to boost the remote sensing services.
  • Radar Imaging Satellites: The satellites, RISAT-1 and RISAT-2, focus on providing images, which have vivid, coarse and high spatial resolutions.
  • Kalpana-1: Kalpana-1, initially called as GSAT series, is the series of the geostationary satellites meant for experimental purposes. The name of the satellite series was kept after late Indian born NASA astronaut Kalpana Chawla.
  • SARAL: The Indo-French satellite is used for monitoring the sea-levels and oceans surface.

ISRO also built two satellite navigation systems namely, GAGAN (GPS Aided GEO Augmented Navigation) satellite navigation system and IRNSS (Independent Regional Navigation Satellite System) satellite navigation system.

Latest Invention by ISRO

ISRO has used a scramjet engine to launch a rocket, which will help them develop an air breathing propulsion system. They used scramjet engine in place of liquid and cryogenic fuels because Scramjet-powered rockets show greater thrust than the above-mentioned fuels. On successfully developing the project, ISRO has now entered into an elite club.

Career in ISRO

ISRO conducts their own tests for various posts and allow only those candidates to appear in the test, whose CGPA is equal to or more than 6.84 and in case of percentage, it needs to be at least 65%.

For most of the jobs, they set an age limit of 35 years.

The recruitments are conducted through ICRB, which means ISRO Centralised Recruitment Board.

Do not forget to carry your original documents at the time of interview.

If selected, ISRO offers you a salary of no less than 15.6K and no more than 46K. They have different centers all across India, you can be placed in any of the centers.
