UPSC Practice Questions on NASA Space Missions

Q1. Consider the following statements
1. The NewSpace India Limited is the commercial arm of the Department of Space
2. Indian National Space Promotion and Authorisation Center IN-SPACe will facilitate the participation of private sector
Which of the above is/are correct?
1. 1 only
2. 2 only
3. Both 1 and 2
4. Neither 1 nor 2

Answer: 3
Solution: The new Indian National Space Promotion and Authorisation Center IN-SPACe, which is expected to be functional within six months, will assess the needs and demands of private players, including educational and research institutions, and explore ways to accommodate these requirements in consultation with ISRO. Existing ISRO infrastructure, both ground- and space-based, scientific and technical resources, and even data are planned to be made accessible to interested parties to enable them to carry out their space-related activities.

It is not that there is no private industry involvement in Indias space sector. In fact, a large part of the manufacturing and fabrication of rockets and satellites now happens in the private sector. There is increasing participation of research institutions as well. But as Sivan told this newspaper on Thursday, the Indian industry had a barely three per cent share in a rapidly growing global space economy which was already worth at least 360 billion dollars. Only two per cent of this market was for rocket and satellite launch services, which require fairly large infrastructure and heavy investment. The remaining 95 per cent related to satellite-based services, and ground-based systems.

Indian industry, however, is unable to compete, because till now its role has been mainly that of suppliers of components and sub-systems. Indian industries do not have the resources or the technology to undertake independent space projects of the kind that US companies such as SpaceX have been doing or provide space-based services.

Additionally, the demand for space-based applications and services is growing even within India, and ISRO is unable to cater to this. The need for satellite data, imageries and space technology now cuts across sectors, from weather to agriculture to transport to urban development and more. As Sivan told this newspaper, ISRO would have to be expanded 10 times the current level to meet all the demand that is arising.

At the same time, there were several Indian companies waiting to make use of these opportunities. Sivan said there were a few companies that were in the process of developing their own launch vehicles, the rockets like ISROs PSLV that carry the satellites and other payloads into space, and ISRO would like to help them do that. Right now, all launches from India happen on ISRO rockets, the different versions of PSLV and GSLV. Sivan said ISRO was ready to provide all its facilities to private players whose projects had been approved by IN-SPACe. Private companies, if they wanted, could even build their own launchpad within the Sriharikota launch station, and ISRO would provide the necessary land for that, he said.

IN-SPACe is supposed to be a facilitator, and also a regulator. It will act as an interface between ISRO and private parties and assess how best to utilize Indias space resources and increase space-based activities.
