The Indian Space Research Organisation (ISRO) is India's space agency, established in 1969 with a vision to use space technology for national development. ISRO has launched many satellites using its family of launch vehicles like PSLV and GSLV. Notable missions include India's first satellite Aryabhata launched in 1975, INSAT for telecommunications, and Indian Remote Sensing satellites which form the largest civilian remote sensing constellation. Current and future missions include Chandrayaan-2 to the moon, Aditya-1 solar mission, and development of reusable launch vehicles. ISRO has achieved numerous firsts for India including successful Mars and moon missions.

2. The Indian Space Research Organisation (ISRO) is the
space agency of the government of INDIA.
 Its vision is to "harness space technology for
national development", while pursuing space science
research and planetary exploration.
 ISRO lanched many space satlites since it's
formation .
 Now ISRO is not only an official representative of
Indian space program , it becomes a leader of
global satlite market with much reliability .

6.  India's first satellite, the Aryabhata, was
launched by the Soviet Union on 19 April
1975 from Kapustin Yar using a Cosmos-3M
launch vehicle.
 INSAT (Indian National Satellite System) is a
series of multipurpose geostationary
satellites launched by ISRO to satisfy the
telecommunications, broadcasting,
meteorology and search-and-rescue needs of
India.

7.  Indian Remote Sensing satellites (IRS) are a
series of earth observation satellites provides
remote sensing services to the country. The
Indian Remote Sensing Satellite system is the
largest constellation of remote sensing
satellites for civilian use in operation today in
the world.
 GAGAN satellite navigation system is an
indigenous Satellite-Based Regional GPS
Augmentation System as part of the Satellite-
Based Communications, Navigation and
Surveillance (CNS)/Air Traffic Management
(ATM) plan for civil aviation.

8.  IRNSS satellite navigation system is an
independent regional navigation satellite
system is designed to provide accurate
position information service to users in India
as well as the region extending up to 1500
km from its boundary.
 The maximum number of satellites launched
by the PSLV in a single launch is 20, in the
PSLV-C34 launch on 22 June 2016.

9.  Chandrayaan-1 was India's first mission to
the moon. ISRO launched the spacecraft using
a modified version of the PSLV on 22 October
2008 from Satish Dhawan Space Centre,
Sriharikota. The vehicle was successfully
inserted into lunar orbit on 8 November
2008.
 Chandrayaan-1 became the first lunar
mission to discover existence of water on the
Moon.

11.  The Mars Orbiter Mission or Mangalayaan,
was launched into Earth orbit on 5 November
2013 by ISRO and has entered Mars orbit on
24 September 2014.
 India is the first country to enter Mars orbit
in first attempt.
 It was completed at a record cost of $74
million.

12.  Reusable Launch Vehicle-Technology
Demonstrator (RLV-TD).
 The ULV or Unified Launch Vehicle is a launch
vehicle in development that will enable the
replacement of the PSLV, GSLV Mk I/II and
GSLV Mk III with a single family of launchers.
 Chandrayaan-2 will be India's mission to the
Moon which will include an orbiter and
lander-rover module. Chandrayaan-2 will be
launched (by GSLV-MkII) around 2016–2017 .
 Aditya-1 (400kg) is the First Indian space
based Solar Coronagraph to study solar
Corona in visible and near IR bands.
