India must build its own space station

India should actively get into building its own space station in the Low Earth Orbit (LEO) as its next space frontier since the time is opportune for this, a retired space scientist has said.

According to M.Y.S. Prasad, who retired as director of the Satish Dhawan Space Centre (SDSC), India should have long-term strategic goals that will have a cascading technological benefit across several areas.

"It is time to look 10-15 years ahead rather than planning for incremental growth activities. Building our own space station will be beneficial on many counts and would also generate around 15,000 high-skilled jobs," the distinguished scientist, a 2014 recipient of the Padma Shri, India's fourth highest civilian honour, told IANS.

Simply put, a space station is a manned satellite in a Low Earth Orbit.

"The future of International Space Station (ISS) is not known post 2025. Then there will only be the Chinese space station in the orbit," Prasad said.

Ruling out the possibility of developed countries coming together again to put up a space station, Prasad said it is an opportune time for India to do that and start planning for it.

"The decision to have a space station will have a positive effect on other connected projects. The plan to have a space station will result in accelerated development of reusable rockets, in-orbit docking systems, manned mission and others," Prasad said.

He said the technology development needed for manned missions to Low Earth Orbit and space stations in Low Earth Orbit will enhance the knowledge and competence of the country`s space agency -- Indian Space Research Organisation (ISRO) -- and the industrial capacity of the country.

The research and development (R&D) activities in these areas need the evolution of re-entry technologies, life support systems, safe recovery systems, more reliable launch and spacecraft systems, long-term platforms operating in space for specialised experiments and others, Prasad remarked.

He said India should get into the development of a rocket that can carry 7.5 tonnes into a Geo-stationary Transfer Orbit (GTO) and 10 tonnes into Low Earth Orbit.

"Such a rocket will cater to India`s needs of launching heavier satellites as well as the space station," Prasad said.

The setting up of a space station will result in the development of orbit-docking technology which countries like the US, Russia and China now possess.

"There can be a possibility of India-China cooperation in the space station sector like the US and Russia joining hands," Prasad said.

According to him, a firm step towards such a long-term goal will be to commit steady budgetary support for the space sector.

Apart from technological development, space stations will enable long-duration manned space missions.

On the strategic side also, space stations will be of immense use.

"Further, instead of launching remote sensing satellites at regular intervals, the space station can act as one," Prasad said.

Agreeing that India should look far as regards space sector goals, former ISRO chairman U.R. Rao told IANS: "Today manned mission is not for prestige. It has become important."

Space agency officials told IANS that the sector got the budgetary support it needed from successive governments.

Earlier India did not look at manned mission and other projects as the cost-benefit ratio was not in favour and hence the focus was on launching communication and remote sensing satellites.

However, former ISRO chairman K. Radhakrishnan offered an alternative instead of India building its own space station.

"India could look at conducting tests at the International Space Station rather than building its own," Radhakrishnan told IANS.

According to him, it is certainly in India's plans to have an Indian presence in the solar system.

"Developing the necessary technology, building and maintaining the space station involve huge financial outlay. Human flight is what ISRO should look at," Radhakrishnan said.

According to Prasad, investment in space technologies cannot be looked in the short-term perspective of cost-benefit ratio.
