ISRO aims for the space tourism

The Indian Space Research Organisation (ISRO) is known to be taking space tourism very seriously. With the new chief Dr K Radhakrishnan in position, the organization is exploring new strategies and technologies for low cost space tourism. Thus far space tourism has been very expensive. The Russian Space Agency is providing space tourism. A flight on the Soyuz to the International Space Station is known to have been costing $20-35 million. The space tourists also conduct research for third parties.
“Space tourism is something where India can play a niche role with its affordable solutions. However, this will take some time. India’s Chandrayaan programme was less costly than the private jet gifted by Mukesh Ambani to his wife.” says Ajey Lele from the Institute for Defence Studies and Analyses (IDSA). A space tourism operator called Virgin Galactic has been charging $200,000 for a few minutes of space experience.

ISRO’s cryogenic tech will be a game-changer in space

Success of the indigenous cryogenic engine technology will bolster India's attempts to become a full-fledged competitor in the $4 billion global satellite launch services market. Until now, the Indian Space Research Organisation (ISRO) has used Russian-made cryogenic engines for putting its satellite launch vehicles into space.The polar satellite launch vehicle (PSLV) is used for launching remote sensing satellites into polar orbits and geosynchronous satellite launch vehicle (GSLV) for launching communication and meteorological satellites into geosynchronous transfer orbit.But later this month, if the Indian space agency's attempt to launch its largest rocket, the GSLV-D3 with an indigenous cryogenic engine succeeds, then India will join the elite club of five nations in the world to have successfully developed such technology.For the country's rocket scientists, the yet-to-be-achieved breakthrough is significant on two fronts--one, they will achieve self reliance and conf…

ISRO exploring low-cost access to space
