INDIAN ROCKET THAT US ONCE ‘GROUNDED’ WILL PUT ISRO-NASA SATELLITE IN SPACE INDIAN ROCKET THAT US ONCE ‘GROUNDED’ WILL PUT ISRO-NASA SATELLITE IN SPACE - In 1992, the US under President George Bush had slapped sanctions on Indian Space Research Organisation (Isro) and prevented Russia from sharing cryogenic engine technology with the Indian space agency so as to check India from making missiles. Two decades later, US space agency Nasa has joined hands with Isro to co-develop the world's most expensive earth imaging satellite that will cost the two countries over $1.5 billion. The irony is GSLV, which is likely to place this Nasa-Isro Synthetic Aperture Radar (NISAR) satellite into orbit in 2021, is the same rocket for whose cryogenic engine the US put sanctions on India.    More

RUSSIA JUST REACTIVATED 3 MYSTERY SATELLITES - AND WE STILL DON'T KNOW WHY THEY EXIST RUSSIA JUST REACTIVATED 3 MYSTERY SATELLITES - AND WE STILL DON'T KNOW WHY THEY EXIST - Three Russian satellites that were sent into low orbit in 2013 are on the move again, and no one knows what they are for, The Daily Beast reports. Having been idle for more than a year, one of the satellites went hundreds of metres off its orbit last month to within 1,200 metres of a piece of a Chinese weather satellite that China smashed in a 2007 anti-satellite rocket test. The manoeuvre, which is pretty impressive for such a small spacecraft, is also rather close by orbital standards.   More

SPACE DEBRIS AND THE PRICE OF BEING A PIONEER SPACE DEBRIS AND THE PRICE OF BEING A PIONEER - Scientists will tell you, "Space debris is an urgent issue. We've got novel technology to deal with it. But we can't get the funding." It's a lot like climate change. But do we really want to wait until it's too late? Pioneers carry a heavy burden. Everything is new and you're the first to try them out. If you fail, it's moon dust on your face. And those who follow will follow you with the benefit of being able to learn from your mistakes.   More

HOW BUILDING SATELLITES IN ORBIT WILL CHANGE OUR FUTURE IN SPACE HOW BUILDING SATELLITES IN ORBIT WILL CHANGE OUR FUTURE IN SPACE - Satellites lead a double life. Our sats are designed to survive in two very different environments: the microgravity of orbit and the intense forces of a rocket launch. But the extensive support structures they need to endure the brutal trip off-planet are useless once the launch is over. And what's more, having to build satellites this way limits their effectiveness in orbit because it restricts the size of components like transmitters and solar arrays, as well as the choice of materials that can be used in construction.   More
