 Indian Space Research Organisation (ISRO) has successfully launched the ‘RISAT-2B’ Satellite from the Sriharikota’s, Satish Dhawan Space Centre, SHAR. The Polar Satellite Launch Vehicle (PSLV-C46) lifted-off from the First Launch Pad and injectedRISAT-2B into an orbit of 556 km, about 15 minutes and 25 seconds after lift-off. The RISAT-2B is a radar imaging earth observation satellite, weighing about 615 kg. The satellite is intended to provide services in the field of agriculture, forestry and disaster management. The all-weather, radar imaging satellite has the capability to observe and image the earth from about 500 kms. |

 After decades of ground-breaking laboratory works, the world’s scientific and technical community, in a landmark and historic decision has unanimously adopted the resolution to redefine four of the seven base units, the kilogram (SI unit of weight), Kelvin (SI unit of temperature), mole (SI unit of amount of substance), and ampere (SI unit of current). |
| This decision has now enabled scientists and researchers to base the SI units entirely on fundamental properties of nature, which will ensure their ongoing refinement and improvement for years to come. The fundamental constants are invariants of time and space and successfully replaced the artifact based units, and aptly opened up the new era for quantum world by linking all seven base units to fundamental constants/quantum standards. |
| The new SI is being implemented worldwide from 20th May 2019 i.e. the World Metrology Day. The World Metrology Day (WMD) is celebrated annually on this very day as the Metre Convention was signed by representatives of seventeen nations on May 20, 1875. On this occasion, CSIR-NPL also published a book entitled, “Redefined SI Units and Glimpses of NPL Metrological Activities” of almost 100 pages. |

 Microsoft has unveiled fully-managed Azure Blockchain Service that would simplify the formation, management, and governance so that businesses can focus on workflow logic and application development. Instead of supporting cryptocurrency transactions, Azure Blockchain Service will let businesses develop their applications on its Cloud-based platform. Microsoft has also announced a partnership with J.P. Morgan to make “Quorum“, the first ledger available in Azure Blockchain Service. |

 The most powerful operational rocket in the world, SpaceX’s Falcon Heavy, launched its first commercial mission from Florida in a key demonstration for billionaire entrepreneur Elon Musk’s space company in the race to grasp lucrative military launch contracts. The 23-story-tall Heavy, which previously launched Musk’s cherry red Tesla roadster to space in a 2018 debut test flight, blasted off from Florida’s Kennedy Space Center carrying its first customer payload. |

 Astronomers have taken the first-ever image of a black hole, which is located in a distant galaxy known as ‘Messier 87’ (M87). The image which has been captured by a network of eight telescopes across the world shows an intensely bright ‘ring of fire’ surrounding a perfectly circular dark hole. The ‘Event Horizon Telescope’ captured the image from the galaxy that is 50 million lightyears away. |

 South Korea launches the world’s first fully-fledged 5G mobile networks. The system will bring smartphones near-instantaneous connectivity 20 times faster than the existing 4G allowing users to download entire movies in less than a second. It is crucial for the future development of devices ranging from self-driving vehicles that send data traffic to one another in real time, industrial robots, drones and other elements of the Internet of Things. |

 The Indian Space Research Organisation (ISRO) has launched a Defence Intelligence Satellite, EMISAT in its 47th Polar Satellite Launch Vehicle (PSLV) mission, along with 28 other customer satellites, onboard the advanced PSLV-C45 Rocket. The PSLV C45 was launched from ISRO’s Satish Dhawan Space Centre in Sriharikota.It is the first time ISRO is launching satellites in three different orbits. Along with that, the PSLV-C45 launch vehicle is also the first PSLV rocket to use four strap-on motors. |
