  • Set to arrive on the planet in February 2021, the rover will study a region of Mars where the ancient environment may have been favorable for microbial life.
  • It will collect samples of soil and rock and cache them on the surface for potential return to Earth by a future mission.
  • The mission is the first step in a potential multi ­mission campaign to return carefully selected and sealed samples of Martian rocks and soil to Earth.
  • It results important milestone in NASA’s Journey to Mars to find whether life has ever existed on Mars, and to advance our goal of sending humans to the Red Planet.

4) NASA announces discovery of 104 new planets outside solar system.

  • A team of researchers of NASA has announced the discovery of 104 new planets outside our solar system including four that could have Earth-like, rocky surfaces.
  • Scientists discovered the exoplanets in Hawaii using Kepler space telescope as well as ground observations by Earth-based telescopes, including four on the summit of Mauna Kea in Hawaii.
  • The unmanned Kepler mission has been scanning 150,000 stars in the Cygnus constellation for signs of orbiting bodies, particularly those that might be able to support life.
  • The $600 million Kepler mission has allowed scientists to discover more than 4,600 planets 2,326 of them confirmed since it launched in 2009.

 

5) Glaciers melting at 5 to 20 metre rate annually.

  • Majority of glaciers in India including Gangotri are retreating (melting) at varying rates ranging from 5 to 20 meter per year due to global warming.
  • It was announced by Minister of State (independent charge) of Environment, Forest and Climate Change Anil Madhav Dave in Lok Sabha.
  • The revelations were based on the studies carried out by ISRO, Wadia Institute of Himalayan Geology (WIGH) Dehradun and other institutions.
  • Gangotri, one of the largest glaciers (30 km long) of Uttarkahand followed by Satopanth glacier (14 km) are retreating but not at an alarming rate.

6) Genes of 6000-year-old barley grains sequenced for first time.

  • Scientists for the first time succeeded in sequencing the genes in 6000-year-old barley seeds.
  • With this, the ancient barley has become the oldest plant genome to be reconstructed to date. Before this, only prehistoric corn was genetically reconstructed.
  • The 6000-year-old Chalcolithic barley grains were retrieved from Yoram Cave in Israel, close to the Dead Sea.
  • Genetically, the prehistoric barley is very similar to present-day barley grown in the Southern Levant.
  • It supports the existing hypothesis of barley domestication having occurred in the Upper Jordan Valley.
  • The analysed grains, together with tens of thousands of other plant remains, were retrieved during a systematic archaeological excavation headed by Uri Davidovich, from The Hebrew University of Jerusalem, and Nimrod Marom, from University of Haifa in Israel.
  • In order to determine the age of the ancient seeds, the researchers split the grains and subjected half of them to radiocarbon dating. The other half of the grain was used to extract the ancient DNA.

7) Teal unveils world`s fastest production drone.

  • US-based startup, Teal has unveiled what it claims is the world`s fastest production drone.
  • It can fly at speeds up to 112 kmph, has a two-mile range and 20-minute flight time and can withstand winds traveling at 64 kmph.
  • The $1299-drone features a 13 MP 4K camera and offers built-in apps for controlled flying, racing and follow mode.

8) Face book’s Aquila Internet drone completes first test flight.

  • Facebook Inc announced the successful completion of test flight of a solar-powered drone named Aquila.
  • The social media giant believes that Aquila will help to extend Internet connectivity to every corner of the planet.
  • The company ultimately hopes to have a fleet of Aquilas that can fly for at least three months at a time at 60000 feet and communicate with each other to deliver internet access.
