May 11: National Technology Day

Every year, `National Technology Day’ is observed across India on May 11.

This day glorifies the importance of science in day-to-day life and motivates students to adopt science as a career option.

National Technology Day is being commemorated to celebrate the anniversary of first of the five tests of Operation Shakti (Pokhran-II) nuclear test which was held on 11 May 1998 in Pokhran, Rajasthan.

Apart from Pokhran nuclear test, on this day first indigenous aircraft Hansa-3 was test flown at Bangalore and India also conducted successful test firing of the Trishul missile on the same day.

Considering all these achievements 11 May was chosen to be commemorated as National Technology Day.

To commemorate this day, Technology Development Board (TDB) has instituted a National Award. This award is conferred on to various individuals and industries for their successful achievement in commercialization of Indigenous Technology.

Huge Lava Lake Spotted on Jupiter’s Moon Io

Huge Lava Lake was spotted on Jupiter’s Moon Io by an extremely powerful telescope on Earth named Large Binocular telescope Interferometer (LBTI).

LBTI located on Mount Graham in Arizona, United States had taken highest resolution ground-based images of Io. This finding was published in the Astronomical Journal.

Images have revealed that the lava lake has thick lava crust which has solidified onto it. This thick lave crust periodically sinks into the lake as it fills up with lava, and then it cools off again.

The discovery provides clues to the interior structure and plumbing of the moon Io. It will also help to pave the way for future NASA missions such as the Io Volcano Observer.

About Jupiter’s Moon Io

  • Io is one of the innermost of the four moons of Jupiter which was discovered by Italian scientist and scholar Galileo (Galilei) in 1610.
  • It is named Loki after the Norse god who is often associated with fire and chaos. Its volcanic feature is called a patera.
  • Loki is 200km in diameter and located at least 373 million miles from Earth.
  • It is one of the most geologically active body in our solar system and has hundreds of volcanic areas dot on its surface, which is mostly covered with Sulphur and Sulphur dioxide.

NASA’s 10-Engine Electric Plane named GL-10 Completes Flight Test

NASA successfully tested a 10-Engine Electric Plane named Greased Lightning-10 (GL-10) that that can take off and land like a helicopter and fly efficiently like an aircraft.

During several test flights, remotely piloted GL-10 prototype successfully transitioned from hover to wing-borne flight.

Key features of NASA’s Greased Lightning-10 (GL-10)

  • GL-10 is remotely piloted plane similar as Unmanned Aerial Vehicle (UAV).
  • It is designed and developed in such a way that it can take off like a helicopter and fly like an airplane.
  • It is a battery-powered 10-engine and has a 3.05 meters wingspan. 8 electric motors are mounted on the wings. 2 electric motors are mounted on the tail.
  • It weighs a maximum of 28.1 kilogrammes at take-off.
  • Due to its versatile vertical takeoff and landing ability produces less noise.
  • Applications: Can be used as UAV for small package delivery or vertical take-off and landing, long endurance surveillance for agriculture, mapping and other applications.
  • Its modified scaled up version can be used as four person size personal air vehicle.
