VL-SRSAM: Successful Launch of Short Range Surface to Air Missile

Tags: Science and Technology

Recently Vertical Launched Short Range Surface to Air Missile (VL-SRSAM) was successfully flight tested from an Indian Naval Ship at Integrated Test Range (ITR), Chandipur, Odisha.

  • The test was conducted jointly by the Defence Research and Development Organisation (DRDO) and the Indian Navy.

  • About VL-SRSAM -

  • The VL-SRSAM has been jointly designed and developed by three units of the Defence Research and Development Organisation for deployment on warships of the Indian Navy.

  • The missile has the capability to neutralise various airborne threats at close range including sea-skimming targets.

  • Sea skimming is a technique used by many anti-ship missiles and some fighter or strike aircraft to evade radar and infrared detection.

  • The missile is designed to strike high-speed air targets at a range of 40 to 50 km and an altitude of about 15 km.

  • Its design is based on the Astra missile, which is an air-to-air missile beyond visual range.

  • Features

  • Cruciform Wings: They are four small wings arranged like a cross on four sides and provide a stable aerodynamic position to the projectile.

  • Thrust vectoring: It is the ability to change the direction of thrust, angular velocity and position of the missile with its engine.

  • Thrust is the force that moves the aircraft through the air.

Canistered System: It controls the environment inside, thus making it easier to transport and store, and to make the weapon durable.

Microplastics found in Antarctica for first time

Tags: Popular Science and Technology

Scientists have found microplastics in fresh ice in the Antarctic for the first time.

  • Scientists have warned that the microplastics in the fresh snow of Antarctica would accelerate the process of melting of ice. 

  • The researchers found an average of 29 microplastic particles per litre of melted snow.

  • There were 13 different types of plastic found.

  • The findings, published in The Cryosphere Journal, point to a serious threat to the Antarctic region.

  • Impact of microplastic on environment

  • Studies have shown that microplastics negatively impact the health of the environment, as well as limit the growth, reproduction and normal biological functions of organisms.

  • Studies show that the global usage of plastic is set to increase by three fold by the year 2060. 

  • Microplastics have been discovered inside fish and under Arctic ice in the deepest ocean depths.

  • Microplastics if found in humans have negative health effects.

  • In 2019, Alex Aves, a PhD student at the University of Canterbury in New Zealand, collected ice samples from the Ross Ice Shelf in Antarctica.

  • The researchers found in the laboratory that every sample from even remote sites on the Ross Ice Shelf contained plastic particles.

  • Microplastics were found in ice samples from 19 sites in the Ross Island region of Antarctica.

  • What are Microplastics?

  • These are defined as plastics less than five millimetres in diameter.

  • They are small plastic particles that result from commercial product development and the breakdown of larger plastics.

  • Microplastics are non-degradable and insoluble in water.

  • As a pollutant, microplastics can be harmful to the health of the environment, humans and organisms.

‘Abnormal’ dinosaur egg found in India

Tags: Science and Technology

Researchers from Delhi University have discovered a unique set of fossilized dinosaur eggs in Dinosaur Fossils National Park in Dhar district of Madhya Pradesh, with one egg nesting inside another.

  • Eggs within eggs are a rare phenomenon, found only in birds and never in reptiles.

  • This discovery brings to the new links between reptiles and avian evolution.

  • The findings of discovery are published in the journal 'Scientific Reports'.

  • The Upper Cretaceous Lameta Formation of Central India is long known for its dinosaur fossils.

  • Scientists found evidence of 52 titanosaurid sauropod nests near Padalia village near Bagh town in Madhya Pradesh.

  • One of these nests contained 10 eggs, one of which was an "abnormal" egg.

  • About Dinosaur

  • Dinosaurs of the Sauropod family were among the largest animals ever found on land and were found in India millions of years ago.

  • Dinosaurs are a diverse group of reptiles.

  • Fossils of these animals have also been found in Gujarat, Madhya Pradesh and Meghalaya.

  • Most Dinosaurs died out by the end of the Cretaceous period.

  • Modern birds are a type of dinosaur because they share a common ancestor with non-avian dinosaurs.

  • Dinosaur fossils have been discovered on all seven continents.

  • All non-avian dinosaurs became extinct about 66 million years ago.

  • The earliest known dinosaurs look during the Triassic period (about 250 to 200 million years ago).

  • One of the biggest dinosaurs was the Argentinosaurus.

  • Lizards, turtles, snakes and crocodiles are all descendants of dinosaurs.

  • Dinosaurs could not survive and became extinct due to climate change.
