Underground und lake detected on Mars It is the first stable body of liquid water found on the red plant and is about 20 km wide


  • Using a radar instrument on an orbiting spacecraft, scientists have spotted a sizeable salt-laden lake under ice on the southern polar plain of Mars, a body of water they called a possible habitat for microbial life.

Enlighten about the lake

  • The reservoir they detected — roughly 20 km in diameter, shaped like a rounded triangle and located about 1.5 km beneath the ice surface — represents the first stable body of liquid water ever found on Mars.

Enlighten about the detection

  • The detection was made using data collected between May 2012 and December 2015 by an instrument aboard the European Space Agency’s Mars Express spacecraft that transmits radar pulses, which penetrate the Martian surface and ice caps.

Locations’s radar profile

  • This took long years of data analysis to find a good method to be sure that what we were observing was unambiguously liquid water
  • The location’s radar profile resembled that of subglacial lakes found beneath Earth’s Antarctic and Greenland ice sheets.
  • Mars long ago was warmer and wetter, possessing significant bodies of water, as evidenced by dry lake beds and river valleys on its surface.
  • There had been some signs of liquid water currently on Mars, including disputed evidence of water activity on Martian slopes, but not stable bodies of water.
  • The water in the Martian lake was below the normal freezing point but remained liquid thanks in large part to high levels of salts.

  • With the launch of the platform Indians will be able to upload and rate their/organizations innovation on the platform

State Specific

Gurupriya bridge on the river Gurupriya Built at a cost of Rs 187.25 crore in a record time of four years in Chitrakonda, the 910-meter long and 8.4-meter wide bridge provides a vital connectivity to 151 villages.


  • With the inauguration of the much-awaited Gurupriya bridge by Odisha Chief Minister Naveen Patnaik on Thursday, over 150 cut-off villages of Balimela reservoir in the Maoist-infested Malkangiri district got connected to the rest of the State after almost five decades.
  • Announced a special package of Rs 100 crore for the people living in the Swabhiman Areas (formerly known as cut-off areas) in the Maoist hinterland of Odisha's Malkangiri district.
  • The special package includes a fishery project in the reservoir, construction of two roads in the erstwhile cut-off areas, electrification, drinking water supply, provision of healthcare and a new bridge at Manyamkonda.

Enlighten about the bridge

  • The bridge was a dream project of the State government.
  • Over 30,000 tribals of these villages had got cut off from the mainland in 1972 because of the Balimela reservoir created due to a hydel project.
  • Since then the villagers have had to cover distances of up to 60 km by boats
  • Because of its extreme remoteness and only land link with Visakhapatnam district in adjoining Andhra Pradesh, the cut-off region became a safe haven for Maoists.
  • The work order for the bridge was awarded to Gammon India in 2006 but it could not progress due to technical challenges and Maoist threats.
  • The construction of the bridge was also a technical challenge as it had to be erected in 70- to 90-foot-deep water.
  • The bridge took around three and a half years to complete. The Border Security Force had to be deployed in the area for anti-Maoist operations and for providing security cover for the construction work.

Parliament Bills/Amendments

  • It also provides for a Relief and Rehabilitation Committee and Rehabilitation Fund with an initial allocation of ₹ 10 crore.
  • It prescribes forfeiture of property used or likely to be used for the commission of an offence.
  • Begging has been included as an aggravated crime as it involves an extreme form of violence.
  • The bill ensures that the victim is given witness protection during the investigation".
  • The Bill provides for the establishment of a National Anti-Trafficking Bureau to investigate cases.
  • It provides that every state government will appoint a State Nodal Officer, who will be responsible for follow-up action, as per the instructions of the State Anti-Trafficking Committee.
  • The proposed law provides for the setting up of Anti-Trafficking Units at district level and establishment of Anti-Trafficking Relief and Rehabilitation Committees at the national, state and district levels.


  • The provisions for confiscation of properties likely to be misused
  • The need for community-based rehabilitation for survivors.

Science and Technology

Astronomers confirm theory of relativity Einstein’s theory of gravity was upheld in measurements of a star that recently made a close pass by the supermassive black hole at the center of the Milky Way, as shown in this artist’s conception illustrating the star’s trajectory over the past few months.


  • A consortium of astronomers for the first time confirmed a prediction of Albert Einstein’s theory of general relativity by observing the gravitational effects of a supermassive black hole on a star zipping by it.
  • A single star, careening around the monster black hole in the center of the Milky Way, has provided astronomers with new proof that Albert Einstein was right about gravity
  • As light escapes a region with a strong gravitational field, its waves get stretched out, making the light redder, in a process known as gravitational redshift.
  • The scientists, a team known as the GRAVITY collaboration, used the Very Large Telescope array, located in the Atacama Desert of Chile, to demonstrate that light from the star was redshifted by just the amount predicted by general relativity.
  • Scientists have observed gravitational redshift before. In fact, GPS satellites would fail to function properly if gravitational redshift weren’t taken into account. But such effects have never been seen in the vicinity of a black hole.
  • At the Milky Way’s heart there lurks a hulking supermassive black hole, with a mass about 4 million times that of the sun
  • The researchers zeroed in on one star, known as S2, which completes an elliptical orbit around the black hole every 16 years.

Enlighten about the Research

  • Researchers from the GRAVITY consortium led by the Max Planck Institute for Extraterrestrial Physics realised that they had a “perfect laboratory” to test Einstein’s theory with the black hole Sagittarius A* in the centre of the Milky Way.
  • Black holes are so dense that their gravitational pull can trap even light, and the supermassive Sagittarius A* has mass four million times that of our sun, making it the biggest in our galaxy.
  • Astronomers followed the S2 star as it passed close to the black hole on May 19 at a speed in excess of 25 million kmper hour.
  • They then calculated its velocity and position using a number of instruments and compared it with predictions made by Einstein that the light would be stretched by the gravity, in an effect called gravitational redshift. Newtonian physics doesn’t allow for a redshift.
  • The results are perfectly in line with the theory of general relativity” and are “a major breakthrough towards better understanding the effects of intense gravitational fields
