ISRO's space odyssey started on August 15, 1969.
Within six years it achieved its first milestone on April 19, 1975 when the first Indian satellite -- Aryabhatta -- successfully entered outer space with the help of the Soviet space agency. Weighing 360 kg, Aryabhatta had a mission life of just six months. For India, that was its 'one small step, one giant leap' moment.
In many ways, the scale of Isro's space odyssey can be understood from how it journeyed from the age of Aryabhatta in 1975 to the age of something as complex as Chandrayaan-2 in 2019.
In this period, Isro sent 105 Indian satellites into space, developed its own independent launch systems, carried out 75 launches, reached the Moon twice, successfully sent a spacecraft orbiting Mars, besides sending 297 satellites of 33 countries and 10 satellites designed and built by Indian students
Of the 75 launches that Isro has carried out till date, only eight were unsuccessful. Besides this, two satellites failed in their orbits after being successfully launched while one suffered partial failure.

ISRO’s Timeline of Space Programme
1960's: Journey of the formation of ISRO
Year |
About Mission |
1962 |
The Indian National Committee for Space Research
is formed under the leadership of Vikram Sarabhai who is also known as
father of India's space program and physicist Kalpathi Ramakrishna
Ramanathan. |
1963 |
The first sounding rocket is launched from Thumba
Equatorial Rocket Launching Station in Kerala which is used for probing
upper atmospheric regions and space research. It marks the beginning of
the Indian space program. |
1965 |
Space Science and Technology Centre (SSTC) was established in Thumba on 1 Jan, 1965. |
1967 |

1975 |
On 19 April, first Indian Satellite, Aryabhata
was launched into space. It marked a milestone in India's space
programme because it was completely designed in the country and launched
from a Russian facility. |
1977 |

The first experimental remote-sensing satellite
which was built in India was launched namely Bhaskara-I. The images send
by it are used to study hydrology and forestry and oceanographic
studies. |
1980s: Satellite launch Vehicle, Communication satellite, remote sensing satellite launched
Year |
About Mission |
1980 |
India's first experimental satellite vehicle was
launched namely Satellite launch Vehicle-3 (SLV-3) which makes ISRO
sixth nation in space program. SLV-3 launched second time with Rohini.

Developed in 1990s and has become the Indian
space mission's most reliable workhorse. In 1993, PSLV carried out its
