Chandrayaan 3 follows the Chandrayaan 2 mission which did not achieve the desired soft landing on the surface of the moon in 2019, disappointing the scientists.

The mission objective is to ensure data continuity of ocean color and wind vector data to sustain the operational applications.

The 6-metre tall launch vehicle Vikram-S is named after Vikram Sarabhai, the father of the country's space programme and lifted off at 11.30 am.

The Indian Space Research Organisation on Sunday faced a blip in its plan to tap the small satellite launch vehicle market, as an anomaly in the placing of the satellites by the rocket led to deviation on its path thereby becoming 'no longer usable', Chairman S Somanath said on Sunday.

The launch marks a significant milestone for the space agency as it is the 50th flight of PSLV and the 75th vehicle mission from Sriharikota. The 628 kg satellite is meant for applications in various fields like agriculture, forestry and disaster management support. It would also serve military purposes.

The ISRO is aiming for a soft landing of the lander in the South Pole region of the moon where no country has gone so far.

India scripted history by successfully launching EMISAT, a military satellite, and 28 foreign nano satellites on-board its polar rocket from Sriharikota on Monday, in a complex mission which marked many a first for Indian Space Research Organisation.

The mission life of the 2,250kg GSAT-7A, built by ISRO, is eight years. It will provide communication capability to users in Ku-band over the Indian region.

The primary goal of HysIS, whose mission life is five years, is to study the earth's surface in visible near infrared and shortwave infrared regions of the electromagnetic spectrum.

The 3,423 kg GSAT-29 carries Ka and Ku band high throughput transponders intended to meet the communication requirements of users, including in the North East and in Jammu and Kashmir.

The successful orbiting of the satellites by the Polar Satellite Launch Vehicle PSLV C-40 comes four months after the Indian space Research Organisation's mission to launch backup navigation spacecraft IRNSS-1H onboard PSLV-39 ended in a rare failure.

A S Kiran Kumar, chief of ISRO, said the mission was unsuccessful because the satellite housed within the heat sink could not be injected.

Prime Minister Narendra Modi lauded the scientists saying, "with this successful launch, we will determine our own paths powered by our technology".

The Indian Space Research Organisation successfully launched India's fifth navigation satellite IRNSS-1E from Sriharikota.
