Defence Research and Development Organisation (DRDO) has successfully test-fired an indigenously-developed 500 kg class guided bomb from a Sukhoi combat jet at Pokhran in Rajasthan. The 2.5-tonne air-to-surface missile has a range of around 300 km, and it will significantly enhance the IAF's combat capability and  hit the target with high precision. The ministry said, all the mission objectives have been met during the test firing of the bomb, adding it is capable of carrying different warheads.

A resolution to redefine four of the seven base units was passed by representatives of 60 countries at the General Conference on Weights and Measures (CGPM) of the International Bureau of Weights and Measures (BIPM), Paris on 16 November 2018. For the first time, the kilogram has got an update that makes it very accurate. It adopted a global resolution to redefine four of the seven base units – (kilogram, Kelvin, mole and ampere). This is a move expected to have far-reaching effects, including changes in textbooks. Over 100 countries have adopted the metric system of measurements, also known as the International System of Units (SI), which has been in practice since 1889.

A next-generation plastic that can be fully recycled into new materials of any colour, shape, or form, without loss of performance or quality has been created by the scientists. A recyclable plastic that, like a Lego play set, can be disassembled into its constituent parts at the molecular level, has been designed by a team of researchers at the US Department of Energy's (DOE) Lawrence Berkeley National Laboratory.

Common Script

A unified script for nine Indian languages is being proposed as a common script for India. This is developed by a team headed by Professor V. Srinivasa Chakravarthy at IIT-Madras. His team developed a method for reading documents in Bharati Script by using a multi-lingual optical character recognition Scheme which is also known as OCR. The integrated script includes Devnagari, Bengali Gurumukhi, Gujarati, Oriya, Telugu, Kannada, Malayalam and Tamil. This is very similar to the system in European languages. Urdu and English were not integrated so far because of their very different phonetic organisation.

Chandrayaan-2
Dr K. Sivan, the Chairman of the Indian Space Research Organisation (ISRO) announced that India’s second lunar mission Chandrayaan-2 is scheduled to be launched between 9th and 16th of July 2019. Dr. Sivan is popularly known as the "Rocket Man" for his significant contribution to the development of cryogenic engines, for India's space programme. The Chandrayaan-2 lander will touch down near Moon’s South Pole.
Lunar’s South Pole would be historically significant as it would give ISRO opportunity to name that site on the moon. It was stated by the chairperson of ISRO, on 6th September 2019. Chandrayan-2 mission would land on southern pole of the moon, which is still to be explored by any of the countries in the world. Therefore landing of spacecraft near South Pole of the Moon would be historically significant for ISRO.
