ISRO chairman AS Kiran Kumar on Monday said the country has the capability to set up a space station, but it needed a long-term approach and an ambitious planning.
His comment follows Indian Space Research Organisation (ISRO) display of technological prowess last week by launching 104 satellites in a single mission.
“We have all the capabilities to set up a space station. The day the country takes the decision, we will ‘ok’ the project. Just draw a policy and provide us necessary funds and time,” Kumar said here.
He was in the city to attend the foundation day ceremony of Raja Ramanna Center for Advanced Technology (RRCAT).
“We still talk about what would be the immediate benefits of a manned space mission. That is why the country hasn’t made up its mind about when to invest in a space station,” he said.
A long-term thinking was needed for setting up a space station, he said, adding “the sooner the better.”
Kumar said ISRO was also mulling tying up with the industry to enhance the country’s satellite launching capability.
Many more satellites were needed to keep a tab on the land and weather conditions and to enhance the communication network, he said.
This would be possible with increase in the number of satellite launches, for which the country needed to enhance the basic infrastructure and reduce the cost of equipment, he added.
The number of companies manufacturing small satellites has gone up across the world, but these companies could not launch them, therefore this area had immense commercial potential and India could tap it by enhancing the launch facilities, the ISRO chief said.

The researchers found that powerful radio jets from the black hole are stimulating the production of cold gas in the galaxy’s extended halo of hot gas. This supply of cold gas could eventually fuel future star birth

In a surprising discovery, astronomers have observed a black hole producing cold, star-making fuel from hot plasma jets and bubbles.
The researchers found that powerful radio jets from the black hole — which normally suppress star formation — are stimulating the production of cold gas in the galaxy’s extended halo of hot gas.
This newly identified supply of cold, dense gas could eventually fuel future star birth as well as feed the black hole itself, said the study published in the Astrophysical Journal .
The researchers studied a galaxy at the heart of the Phoenix Cluster, an uncommonly crowded collection of galaxies about 5.7 billion light-years from Earth.
The team analysed observations of the Phoenix cluster gathered by the Atacama Large Millimeter Array (ALMA), a collection of 66 large radio telescopes spread over the desert of northern Chile. The researchers believe that the new findings may help explain the Phoenix cluster’s exceptional star-producing power. They may also provide new insights into how supermassive black holes and their host galaxies mutually grow and evolve.
“With ALMA we can see that there’s a direct link between these radio bubbles inflated by the supermassive black hole and the future fuel for galaxy growth,” said study lead author Helen Russell, an astronomer with the University of Cambridge in Britain.

What the researchers believe to be happening is that, as jets inflate bubbles of hot gas near the black hole, they drag behind them a wake of slightly cooler gas.

The bubbles eventually detach from the jets and float further out into the galaxy cluster, where each bubble’s trail of gas cools, forming long filaments of extremely cold gas that condense and rain back onto the black hole as fuel for star formation.IANS
