  ISRO has transferred its indigenous technology to produce space-grade Li-Ion cells to Bharat Heavy Electricals Limited (BHEL). In March 2018, BHEL signed the Technology Transfer Agreement with ISRO for acquiring the Li-Ion Cell production technology. This production facility is primarily targeting to meet Li-Ion Cell requirements for ISRO and other strategic sectors. BHEL can also produce and sell Li-Ion cells for meeting other national/commercial applications by suitably modifying the space-grade cell which can lead to cost reduction. BHEL is in the process of establishing the Li-Ion production facility near Bangalore in Karnataka.

  India’s Polar Satellite Launch Vehicle, PSLV-C47 will launch Cartosat-3 and 13 commercial nanosatellites into Sun Synchronous orbit from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota on 25th November. Cartosat-3 satellite is a third-generation agile advanced satellite having high-resolution imaging capability. This will be the 74th launch vehicle mission from SDSC SHAR, Sriharikota. PSLV-C47 is the 21st flight of PSLV in ‘XL’ configuration, that is with 6 solid strap-on motors. PSLV-C47 will also carry 13 commercial nanosatellites from the United States of America as part of a commercial arrangement with NewSpace India Limited (NSIL), Department of Space.

  NASA has detected a massive thermonuclear explosion coming from outer space, caused by a massive thermonuclear flash on the surface of a pulsar. The crushed remains of a star that long ago exploded as a supernova. The explosion released as much energy in 20 seconds as the Sun does in nearly 10 days. NASA’s Neutron Star Interior Composition Explorer (NICER) telescope on the International Space Station (ISS) detected a sudden spike of X-rays on August 20, reports the US space agency. The X-ray burst, the brightest seen by NICER so far, came from an object named “J1808”. The observations reveal many phenomena that have never been seen together in a single burst.

  A team of astronomers has discovered a haul of 20 new moons orbiting the ringed planet, Saturn. This discovery has brought its total to 82 moons, while Jupiter, by contrast, has 79 natural satellites. The moons were discovered using the Subaru telescope on Maunakea, Hawaii. Each of the newly discovered objects in orbit around Saturn is about 5 km in diameter and 17 of them orbit the planet “backwards” i.e. retrograde direction. The other three moons orbit in a prograde direction i.e. the same direction as Saturn rotates. Dr Scott Sheppard of the Carnegie Institution for Science in Washington DC led the team of astronomers including David Jewitt of University of California, Los Angeles (UCLA), and Jan Kleyna of the University of Hawaii.
