ISRO Launches PSLV C-45 Carrying EMISAT with how many Nano satellite?

India successfully completed 'Mission Shakti' operation where it destroyed a live satellite on a low earth orbit (LEO) using an Anti-Satellite (ASAT) missile in three minutes. India has become the 4th country after the US, Russia and China in the world to achieve this historic feat. Anti Satellite weapons also called the ASAT are developed to destroy satellites. Mission Shakti is a joint programme of DRDO and the Indian Space Research Organisation (ISRO). Mission Shakti will help the country in standing strong and secure. It will further protect the nation from disharmony and bring peace.

On January 31,2019, astronomers from Italy, the UK, Germany and the United States discovered newly discovered galaxy consists of red giant particles. Bedin 1 is a new dwarf spheroidal galaxy. This ancient galaxy is one of the oldest galaxy and was named after Luigi Bedin, a researcher at Italy's National Institute for Astrophysics. Bedin 1 is located 28.38 million light years from Earth.

NASA has announced a new space telescope mission dedicated to understanding the origins of life and the universe. It's called the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer or SPHEREx, for short. The space agency is aiming for a 2023 launch. Once SPHEREx is in orbit, it will observe and collect data on over 300 million galaxies, some as far as 10 billion light-years away from Earth, and 100 million stars in our own Milky Way every six months. The space telescope's main goals, though, are to search for water and organic molecules within the Milky Way. It will also look for those ingredients of life in regions where stars are born.

A group of researchers, led by astronomers at San Diego State University, by using data from NASA's Kepler Space Telescope, detected the new Neptune-to-Saturn size planet orbiting between two previously known planets Kepler-47b and Kepler-47c. This new planet named as Kepler-47d. The research was recently published in the Astronomical Journal.According to a new study, Kepler-47d is about seven times larger than Earth and also the largest of the three planets in the Kepler-47 circumbinary system. The Kepler-47 system is approximately 3.5 billion-years-old and it is 3,340 light years away in the direction of the constellation Cygnus.

Karnataka's swimmer Srihari Nataraj has emerged as the most prolific gold medal winner at the Khelo India Youth Games. He has won 7 Gold medals in swimming events. P Likith from Karnataka won five gold medals and a bronze medal in swimming at the Khelo India Youth Games. They both were the most decorated gold medalists of the Games.

China launched two Tianhui II-01 satellites from Taiyuan Satellite Launch Centre, also known as Base 25. The purpose of the satellite is to perform scientific experiments, land resource and geographic survey, and mapping. The satellites were launched by a Long March 4B carrier rocket also known as Chang Zheng 4B. This was the 303rd successful mission of the Long March series carrier rocket.

Space Exploration Technologies Corp. (Space X) launched its 17th commercial resupply mission to the International Space Station (ISS) by using Falcon 9 rocket with Dragon Spacecraft. The 213-foot-tall rocket lifted off from Cape Canaveral Air Force Station in Florida. This mission is a part of NASA's Commercial Resupply Services (CRS) program, which uses commercial spacecraft to deliver cargo to the ISS.

ISRO Planning to Launch 32 Space Missions in 2019. The missions include the second lunar mission Chandrayaan-2 (Rs.800-crore mission) to land on the moon with lander and rover. India's maiden human space mission in 2021-22, Gaganyaan, will also be pursued this year. Among the ISRO's achievements in 2018 were launch of the heaviest satellite GSAT-29 (3,423 kg) on November 14 and building the heaviest communication satellite GSAT-11 (5,854 kg), launched on December 5 onboard the Arianespace space agency's rocket from French Guiana on the north Atlantic coast of South America.

Helium hydride ion (HeH+), the first molecule that formed almost 14 billion years ago, was detected by NASA's flying observatory SOFIA towards a planetary nebula. It is the first type of molecule (first molecular bond) that formed in the universe after the Big Bang. At that time, ionised hydrogen and neutral helium atoms reacted to form HeH+. Once the universe cooled down, hydrogen atoms started to interact with helium hydride, creating molecular hydrogen, which set the stage for star formation. From that point on, stars created the other elements of the cosmos.

A Pune-based IT firm is developing software for the world's largest ground-based telescope, the Thirty Metre Telescope (TMT), which is likely to come up on Mauna Kea in Hawaii. The telescope is being constructed jointly by India, US, China, Japan and Canada and is likely to become operational in the mid-2020s. India is building the telescope's complex optical structure, called the Segment Support Assembly (SSA), which will comprise 492 hexagonal mirror segments, collectively forming the primary mirror. An eight-member team at the IT firm, ThoughtWorks, is designing three different software - Common Software Services (CSS), Data Management Services(DMS) and Executive Software (ES) - to deal with the control systems to manoeuvre the telescope and manage the big data that will be generated once it becomes operational.
