Chandrayaan 3 by ISRO: Chandrayaan-3 is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface. It will be launched by GSLV Mk-III from Satish Dhawan Space Center, Sriharikota. The propulsion module will carry the lander and rover configuration till 100km lunar orbit.
The propulsion module has: Spectro-polarimetry of HAbitable Planet Earth (SHAPE) payload.
Lander payloads: Chandra’s Surface Thermophysical Experiment (ChaSTE): To measure the thermal conductivity and temperature. Instrument for Lunar Seismic Activity (ILSA): To measure the seismicity around the landing site. Langmuir Probe (LP): To estimate the plasma density and its variations. A passive Laser Retroreflector Array from NASA is accommodated for lunar laser ranging studies.
Rover payloads: Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS): For deriving the elemental composition in the vicinity of landing site.
2022 Resilient Democracies Statement:India, along with the G7 nations and four other countries (Argentina, Indonesia, Senegal and South Africa) signed a statement that called for “guarding the freedom, independence and diversity of civil society actors” and “protecting the freedom of expression and opinion online and offline”. These countries have expressed commitment to a rules-based international order.Principles include:
Global Responsibility: This includes promoting respect for the territorial integrity and sovereignty of other countries; Information Environment: Ensuring an open, open, global, interoperable, reliable and secure Internet, etc.Civil Society: This includes protecting the freedom and diversity of civil society workers; Inclusion and Equality: promoting inter-religious dialogue; Social integration and inclusion etc. are included.
EOS-06 satellite: EOS-06 is third generation satellite in the Oceansat series, which provides continued services of Oceansat-2 with enhanced payload capability. The satellite onboard carries four important payloads viz. Ocean Color Monitor (OCM-3), Sea Surface Temperature Monitor (SSTM), Ku-Band Scatterometer (SCAT-3), ARGOS. To observe ocean color data, sea surface temperature and wind vector data to use in Oceanography, climatic and meteorological applications. Also supports value added products such as potential fishing zone using chlorophyll, SST and wind speed and land based geophysical parameters.
Recyclable Plastic:Recently, scientists from Boise State University in the US have just developed a new kind of plastic that, unlike existing plastics, isn’t made from crude oil and its derivatives. The new recyclable plastic is based on Poly(ethyl cyanoacrylate) or PECA, which is prepared from the monomer used to make Super Glue.It is formed through a process of polymerization.It has comparable properties to existing plastics and is stable in hot, humid environments.The long polymer chains of the PECA plastic can be thermally ‘cracked’ at temperatures of 210 °C and the resulting monomers distilled into a clean product to use again.
Ethyl cyanoacrylate is a highly reactive monomer that has been used nearly exclusively to make Super Glue and related fast-setting adhesives.Polymerization is a process in which relatively small molecules called monomers combine chemically to produce a very large chainlike or network molecule, called a polymer.The monomer molecules may be all alike, or they may represent two, three, or more different compounds.
