Cassini beams back images of Saturn’s solstice |
---|
Cassini, spacecraft launched by the United States’ National Aeronautics and Space Administration (NASA), has beamed back images of a giant storm erupting on Saturn as the ringed planet’s solstice arrived on on 25th May 2017, marking a milestone in the mis- sion that is approaching the end of its 20- year-long journey. A planet’s solstice is the longest day of sum- mer in the northern hemisphere and the shortest day of winter in the southern hemi- sphere. On Saturn, it occurs about every 15 Earth years as the planet and its entourage slowly orbit the Sun, with the north and south hemi- spheres alternating their roles as the summer and winter poles. Reaching the solstice, and observing sea- sonal changes in the Saturn system along the way, was a primary goal of Cassini’s Solstice Mission – the second extended mis- sion of the spacecraft. |
DRDO’s aero test range inaugurated |
---|
Over a decade ago, when a new international airport for Bangalore was being planned at Devanahalli, its private developers feared that the new landing site and paths of its civil flights would clash with a World War II air- field, some 70 km away at Kolar. The Defence Research & Development Organisation was using the airfield to test its new projects.To cut the story short, Bangalore (as it was then called) got a new civil airport in May 2008 and, in the bargain, the DRDO got a new flight testing place for itself although much farther than Kolar. The new Aeronautical Test Range (ATR) has been up and running for a few months. It was inaugurated on May 28 by acting Defence Minister Arun Jaitley. |
