Achievements:

  • The first sounding rocket designed and built in India was RH 75 (Rohini-75) launched in 1967. It was launched from TERLS and had a total mass at lift off of not more than 32 kg. The Rohini series was designed and built by the Indian space research organization for atmospheric and meteorological investigations
  • ISRO constructed its own first satellite mission in 1975 and that satellite was named Aryabhata. It was developed by Soviet Union.
  • The first Indian launch vehicle was Satellite Launch Vehicle (SLV) of which SLV-3 was the third generation. It was used to launch the first indigenously built satellite Rohini in the year 1980.
  • In the year, 1982, ISRO put into operation its first communication satellite called the INSAT. It was launched as INSAT-1A but this mission was unsuccessful.
  • ISRO also put into orbit the first Remote Sensing Satellite in the same year 1988.
  • It has three categories of vehicles namely PSLV, GSLV and LVM or GSLV Mark III.
  • ISRO geared up for the first lunar expedition the mission named Chandrayaan I was launched in 2008.
  • Still, perhaps its most ambitious was the launch of the Mars Obiter Mission (MOM) or Mangalyaan in 2014. By doing this India emerged as the first country to have sent a satellite into Mars orbit in the first attempt.
  • ISRO has put into orbit many small satellites most of which are used for testing and experimentation. Such as Aryabhatta and YouthSat etc.
  • Scramjet (Supersonic Combustion Ramjet) Engine – Scramjet or Supersonic Combustion Ramjet was tested by ISRO in August 2016. The former acts as fuel while the latter which is the oxidizer is sourced from the atmospheric air most especially the oxygen.
  • The ISRO in its space programme made the sixth world record in 2017 for launching as many as 104 satellites in one go to the orbit on a single rocket mission.

Some of the major space research of ISRO in recent times: —

  • On February 17, 2022, ISRO has orbited the Earth Observation Satellite named as EOS-04 through PSLV-C52.
  • SSLV (Small Satellite Launch Vehicle): ISRO designed a new generation vehicle termed as SSLV for launching small satellites and was planning for its maiden developmental flight.
  • Chandrayaan-3 Mission: ISRO was able to put a critical mission to the moon titled Chandrayaan-3 which included a lander and rover. This mission was the third mission of India to moon after Chandrayaan-2 (in which ISRO got success of soft landing).
  • Aditya-L1 Mission: This was ISRO’s first solar mission launched in the interest to study Solar Physics. Aditya-L1 mission will be useful for coronal studies, solar wind study and all other solar phenomena and activities.
  • ISRO also achieved the successful launching several satellites in these mission which were meant for social, scientific or other space related usage.

ISRO's Upcoming Missions:

  • Gaganyaan: with it India is trying to send a crew of three persons into a 400 km orbit that too for three days and ensuring their safe homecoming. The stated plan of action is to be implemented through the best of strategies based on state-of-art technologies which are available with international agencies as well with intra-country competence of Indian industry, intellectuality of academicians and research establishment in the country. Gaganyaan’s mission has some prerequisites, namely the development of several vital technologies. These are human friendly launch vehicle for a safe and comfortable ride into space, life support systems to ensure the crew stays healthy in space like environment, availability of safe means to evacuate the crew from the spacecraft, and develop some of the crew management characteristics like how to train the crew for an outing, how to enhance their return to earth etc.
  • NISAR: NISAR is a Low Earth Orbit (LEO) remote sensing satellite mission under implementation from NASA in collaboration with ISRO. NISAR will image the entire planet in 12 days and have spatial and temporal consistency, to better study the Earth’s biosphere, ice sheets, vegetation, biomass, sea level, water table and natural hazards: earthquakes, tsunamis, volcanoes, landslides and more.

Challenges Faced by ISRO:

  • Technological Complexities and Innovation: However as ISRO contemplates the complex Missions like Gaganyaan and Inter-planetary missions, but the problem is trying out new Technologies. These projects demand very complex and reliable technological equipment the qualities of which are not easy to achieve.
  • Financial Resources: As the projects of ISRO are getting challenging, a similar trend in the utilisation of monetary means is observed. Procuring the funds needed for big missions like the Gaganyaan and Chandrayaan is always a bit complex given the stiff international competition and now the new more aggressive private players.
  • Human Resources: ISRO has very competent scientists and engineers but talent is required for new and even more challenging assignments. Another major problem for ISRO is that today’s youths are reluctant to take science and engineering as a career and they can hardly be motivated to participate in ISRO’s missions.
  • International Competition: There is growing competition in the world regarding space. These new and innovative companies include Space-X the futuristic space exploration companies forming a strong market in space. For this reason, ISRO has to not only build up new technological and commercial skills, but also protect its place in the international market.

Way Forward:

  • Financial support in the budget: Central government is enhancing the budget for ISRO and is allocating more and more fund for it so that it can accomplish its planned missions effectively and efficiently. Out of Rs 39,81,205 crore for the year 2023-2024 in Union Budget 2023-2024, Rs 13,700 crore has been proposed for ISRO. This allocation is required for future strategic programs like Gaganyaan, Chandrayaan 3 and other future large scale programs
  • Partnership with private sector: There have been so many policy pointers that the government has made in order to encourage commercial participation in the space industry. Of them one is the move by the Government of India in 2020 to opened up the space industry for private firms and creation of an organization like IN-SPACe (Indian National Space Promotion and Authorization Centre). This enables commercial organisations to book for ISRO’s facilities and launch their own space missions. This would also imply reduced pressure on ISRO in terms of cash outlay and more synergy with the business community.
  • Promotion of technical innovation: The government has extended policy as well as financial support to the ISRO to boost up the IT and technology. Under this there has been a lot of focus on the expenditure in research and development (R & D) on new technologies. For instance, huge capital investment is being made in the development of hypersonic, quantum communication and micro/nano satellites.
  • Human resource development: The government of the nation has come up with several measures that it has instituted to promote Space education in the country. This will in turn encourage the young generation in seeking for a career in space science.
