Indian space exploration pdf




















Vikram Sarabhai also known as founding father of space programme recognised the benefits of space technologies in India. Further, in , the first rocket was launched from India in November 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.

India's Chandrayaan-2 Moon Mission: All you need to know. 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. 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. SLV-3 launched second time with Rohini. The mission was successful. A joint manned mission of India and Soviet Union has been launched. In this mission the first Indian cosmonaut, Rakesh Sharma, spends eight days in Russian space station Salyut 7.

After the launch of Sputnik in he recognized the potential that satellites provided. India's first prime minister, Jawaharlal Nehru, who saw scientific development as an essential part of India's future, placed space research under the jurisdiction of the Department of Atomic Energy in Sarabhai as Chairman in The Indian Rohini programme continued to launch sounding rockets of greater size and complexity, and the space programme was expanded and eventually given its own government department, separate from the Department of Atomic Energy.

In the s Sarabhai had taken part in an early study with NASA regarding the feasibility of using satellites for applications as wide as direct television broadcasting, and this study had found that it was the most economical way of transmitting such broadcasts.

Having recognized the benefits that the satellites could bring to India from the very start, Sarabhai and the ISRO set about designing and creating an independent launch vehicle, capable of launching into orbit, and providing the valuable experience needed for the construction of larger launch vehicles in future. Recognizing the advanced capability India had in building solid motors with the Rohini series, and that other nations had favoured solid rockets for similar projects, the ISRO set about building the technology and infrastructure for the Satellite Launch Vehicle SLV.

Inspired by the American Scout rocket, the vehicle would be a four-stage all-solid vehicle. Meanwhile, India began developing satellite technology anticipating the remote sensing and communication needs of the future.

India concentrated more on practical missions, directly beneficial to people instead of manned space programs or robotic space explorations. The first launch in was a failure, attributed to a control failure in the second stage. By this problem had been worked out. The first indigenous satellite launched by India was called Rohini Following the success of the SLV, ISRO was keen to begin construction of a satellite launch vehicle that would be able to put truly useful satellites into polar orbits.

This vehicle would be designed as India's workhorse launch system, taking advantage of both old technology with large reliable solid-stages, and new liquid engines. At the same time, it was decided by the ISRO management that it would be prudent to develop a smaller rocket, based on the SLV, that would serve as a testbed for many of the new technologies that would be used on the PSLV.

Eventually, the ASLV was flight tested in , but this launch was a failure. In this mission the first Indian cosmonaut, Rakesh Sharma, spends eight days in Russian space station Salyut 7. Developed in s and has become the Indian space mission's most reliable workhorse.

In , PSLV carried out its first mission and its first successful mission was held in next year. No doubt for next 20 years, it launched several satellites for historic missions like Chandrayaan and Mangalyaan. Almost a decade ago, India's first unmanned lunar probe was launched and was a landmark in India's space mission. Do you know that after this ISRO joined an elite list of just six space organisations to send an Orbiter to the moon?

India became the first country in the world to insert a spacecraft into the Martian orbit in its very first attempt. Of these six satellites, TeLEOS-1 is the primary satellite whereas the other five are co-passenger satellites.

This is the thirty third consecutively successful mission of PSLV. What is Space Station and how many Space Stations are present in space? Its headquarter is in Bengaluru. It is among the top six government space agencies in the world where various scientists and technical experts of different fields are working for future space missions. Do you know that ISRO has a record of more than successful space missions?
