The Moon once had an atmosphere: NASA study

NEWS : The Moon once had an atmosphere before 3-4 billion years ago.

HOW DO YOU SAY THAT? About 3.5 billion years ago = due to Intense volcanic eruptions - so much gas was released that it would have formed a thin atmosphere around the Moon. Now, it doesn't have an atmosphere because it is too small and doesn't have a strong magnetic field.

EVIDENCE OF CO : The broad dark patches, now we see on the moon, known as maria were created by large lava flows that later cooled to become basalt plains.

  • The two largest pulses of gases were produced when lava seas filled the Serenitatis and Imbrium basins about 3.8 and 3.5 billion years ago, respectively.

  • Lava samples indicate those magmas carried gas components, such as carbon monoxide, the ingredients for water, sulphur, and other volatile species.

WAY FORWARD : 1. Source of ice trapped in the Moon could be used for drinking water, growing food, and other needs by astronauts. 2. It could also provide fuel and air for both lunar surface operations and even missions beyond the Moon.

THIS DAY, THAT YEAR : NICK AND LED

NEWS : On October 9, 1962, Nick Holonyak, Jr. demonstrated the first practical visible light-emitting diode (LED).

ALL ABOUT LED :

  • Small light sources or thin chips, LEDs become illuminated by the movement of electrons through a semiconductor material.

  • LEDs, known for their energy efficiency and long life, are available in multiple colours now. The bright, white light is the most popular solution for home lighting.

  • In terms of energy savings, LEDs use up to 75% less energy when compared incandescent lamps.

  • In terms of lifetime, LEDs last up to 25 times longer than incandescent lamps and up to three times longer than most compact fluorescent lamps (CFL).

  • LEDs are compact in shape, allowing for flexibility in design.

SCHEMES IN NEWS

SCHEME 1 : Intensified Mission Indradhanush (IMI)

IMPLEMENTATION :The Science and Engineering Research Board (SERB), a Statutory body of the Department will implement the Scheme.

SIGNIFICANCE : The Scheme recognizes the value of collaborative research as a crucial element for information sharing among researchers for updating and acquiring knowledge and skills, and also to draw different perspectives to solve a shared problem.

That's it for today folks!
