10. TESS, NASA’s mission to search for exoplants. The super earth exoplanet is named Gj357 discovered orbiting dwarf star and 22% larger than the earth.and found a planetary system by the name of TOI 270 and is about 73 light years away from earth. Located in the constellation Pictor.

11. Union Minister for communication launched Centre for development of Telematics (C- Dot’s) latest innovations, C sat Fi( C-Dot satellite WiFi), XGSPON 10G symmentrical Passive Optical Network and C- Dot Interoperable set top Box (CiSTB) is based on Optimal Utilization of wireless and satellite communication to extand connectivity to the remote islands and difficult terrains.

12. Russia launched an unmanned rocket carrying life sized robot to the International Space Station from Baikonur cosmodrome in Kazakhstan. Robot named – Fedor(Skybot F850) short for Final Experimental Demonstration Objest Research- is the first sent into space by Russia.

13. Bangladesh is studying the Feasibility of applying STERILE INSECT TECHNIQUE(SIT) to Conrol the dengue outbreak.Team of experts from WHO-FAO and IAEA arrived in Dhaka. SIT is a mosquito fights mosquito technique. Under this radition sterilised male mosquito are released in areas with dengue causing female Adese aegpti mosquitos turning them infertile.This technique has been tested successfully at two sites in Guangzhou in China.

14. Chandrayaa 2 might have failed in an objective, but mission itself is not a failure. Robotic lnder Vikram followed the predetermined descent trajectory and came just within 2 km of the lunar surface before contact was lost. There have been 38 attempts so far by other countries to land a rover on the moon and have succeded only little more than half the time. This april, Israel’s Beresheet lunar crashed to the lunar surface. BUT early January this year , China’s Chang’e-4 touched down on the lunar far side and developed the Yutu-2 rover to explore the South Pole Aitken basin. While the power landing of Vikram and exploration of the moon’s surface for 14 earth days by the Pragyan rover were one of the main objective of Chandrayan 2, it is wrong to think that the mission itself has failed.90-95% of the mission objective have already been “accomplished” The Orbiter is safe in the intended orbit around the moon.Orbits life span will extand to almost seven years. And help making high resolution maps of the (1) Lunar Surface, (2) Mapping the minerals (3) Understanding the moon’s evolution and most mportantly looking for water molecules in the polar regions.

15. Assam tea growers may take AI route : Drones can address shortage of wrkers as well as spray hazardous pesticides with precision.

16. India’s first largest biotechnology conference- the Global Bio-India (GBI) Summit, 2019 concluded in New Delhi. Organised by Department of Biotechnology, Ministry of Science & Technology, Government of India along with Biotechnology Industry Research Assistence Council(BIRAC)

17. PSLV marked its Golden Jubilee on 11 Dec 2019 by injecting India’s advance radar imaging satellite RISAT-2BR1 and nine other customer satellite from Japan, Italy, Israel and the US into their intended orbits. It is its 50^th launch, radar RISAT-2BR1 used for national security. PSLV has failed only twice- maiden flight of PSLV D1 in Sep 1993 and PSLV C-39 in Aug 2017.Duchifat 3, small remote sensing satellite weighing 2.3 kg biult by students from Israel.
