M-Sand

TN M-Sand Manufacturers’ Welfare Association has filed a writ petition to declare the TN Prevention of Illegal Mining, Transportation and Storage of Minerals & Mineral Dealers Rules of 2011 illegal and unconstitutional.

  • Manufactured Sand (M-Sand) is artificial sand produced from crushing hard granite stones into sand sized angular shaped particles, washed and finely graded to be used as construction aggregate.
  • M-Sand is the most effective and efficient substitute for river sand as it is the most robust sand. The size of M-Sand is less than 4.75mm.
  • M-Sand is used for the production of concrete for construction purpose.
  • The demand for M-Sand is high due to the depletion of river sand and fast-growing construction industries.

P-Sand

  • Plastering M Sand (P Sand) is a very fine grade of sand. It is free of silt and clay particles and has denser particle packing than natural sand.
  • It is used for wall plastering and brickwork purpose. It will provide plastering strength to the construction structure.
  • The proper and fine quality of sand material is a must when it comes to providing strength to any sort of building and construction structure.
  • Plastering M Sand is produced from hard granite stone which is cubically in shape with round edges washed and graded with consistency.
  • P Sand is used as a substitute for river sand which is used for preparing concrete, plastering and also other non-concrete constructions like flooring works, etc.

Supersonic Missile Assisted Torpedo System

Defence Research and Development Organisation (DRDO) developed Supersonic Missile Assisted Torpedo (SMART) System gets successfully launched from Wheeler Island in Odisha.

  • The SMART system is a next generation long-range missile-based standoff torpedo delivery system.
  • [A torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target.]
  • The SMART system has been designed to enhance anti-submarine warfare capability far beyond the conventional range of the torpedo.
  • This canister-based missile system consists of advanced technologies viz. 2- stage solid propulsion, electro-mechanical actuators and precision inertial navigation.
  • The missile can cover a range of distances.

Wheeler Island

  • Dr. Abdul Kalam Island, formerly known as Wheeler Island, is an island off the coast of Odisha, India, around 150 kms east of Bhubaneswar.
  • The island was originally named after English commandant Lieutenant Hugh Wheeler.
  • Odisha government has formally renamed it as APJ Abdul Kalam island as a tribute to the former President of India on his 2nd death anniversary (2017).

Black Box of the Earth

A steel vault that will record the Earth’s warming weather patterns is being built in Tasmania Australia, an Australian island state off the south coast.

  • This vault is dubbed as the ‘Black Box of the Earth’, is a 33-foot-long box made of 3-inch-thick steel.
  • The Earth’s Black Box will operate much like a plane’s Black Box, which records an aircraft’s final moments before crashing.
  • It will listen to what we say and do.
  • It will create an archive that could be critical to piecing together the missteps that should humanity be destroyed by climate change.
  • Data - The box will record leaders’ actions (or inaction) by scraping the internet for keywords relating to climate change from newspapers, social media and peer-reviewed journals.
  • It will collect daily metrics - average oceanic and land temperatures, atmospheric carbon dioxide concentration and biodiversity loss.
  • Eventually, the data will be stored on a giant, automated, solar-powered hard drive with a capacity to collect information for about 50 years.
  • Tasmania was chosen for its relative geopolitical and environmental safety.
  • The vault   will be designed to be resilient against threats including cyclones, earthquakes and, with its sloped walls, attacks by vandals.
