Centre For Avian Ecotoxicology Inaugurated In Coimbatore

A National Centre for Avian Ecotoxicology was inaugurated at Salim Ali Centre for Ornithlogy and Natural Sciences (SACON).
The centre, inaugurated by Union Environment and Forest Minister Prakash Javadekar, would explore the impact of chemical contaminants on individual species of birds and, where possible, link them to population and communities.
The centre would study the movement of environmental contaminants such as pesticides, heavy metals, poly-cyclic aromatic hydrocarbons, poly chlorinated biphenyls and drugs through food chain, and their harmful effects on birds.
Ecotoxicological studies assume significance at a time when ecological factors are unable to explain continued mortality of birds leading to population decline over a period of time.
Highlighting the near extinction of vultures, from 40 million to nearly one thousand in India, Javadekar said the Centre had banned diclofenac given to cattle, due to which the vultures were dying.
The Ministry through a project at an estimated cost of Rs 4 crore funded modernising the facility at SACON, a centre of excellence, to handle the challenges posed by the continued entry of newer chemicals into the environment.

Chandrayaan 2 Sends First Moon Picture

Chandrayaan 2, a day old in its orbit around the moon, started undergoing phased manoeuvres to shorten the elliptical orbit in preparation for the September 7, 2019 landing. ISRO compressed the current elliptical orbit to 4,412 km at the far end from the moon.
ISRO chief K. Sivan said the crucial process of taking up soft landing of the Vikram Lander will be taken up in the early hours of September 7, 2019.
Elaborating about the complexity involved, he said the speed of the spacecraft needs to be brought down to "zero".
The Mare Orientale basin and Apollo craters are identified in the picture.

NASA Found More Than 40 Pieces Of Debris Created By India's Anti Satellite Test

More than 40 pieces of debris created by India's anti-satellite test, are still moving around in space even as majority of the debris has disintegrated, a survey conducted by NASA has found.
A report in Orbital Debris Quarterly News journal, published by the National Aeronautics and Space Administration's (NASA) Orbital Debris Program Office, has found that of the 101 pieces that were big enough to be tracked, 49 continue to be in the orbit.
According to the report, it is possible that more pieces created by the test, albeit much smaller in size, are floating in space, but they are not being tracked.
On March 27, 2019, India had shot down its Microsat-R satellite with the intention of demonstrating that it can shoot down space-based infrastructure of an enemy country. The test made India only the fourth country to have demonstrated this capability.

Lens That Works Like Human Eye

A team of researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a new lens that functions a lot like the human eye.
Not only is the instrument capable of focusing in real-time thanks to an elastomer muscle, it features none of the bulk of a traditional spherical lens. It can even do some things the human eye can't, including adjusting for astigmatism and image shift, two variables that lead to blurry vision.
The flat lens design this new artificial eye takes advantage of is called a metalens. It uses tiny nanostructures to focus light. In this way, it's able to focus the entire visible light spectrum at a single point.
By contrast, traditional lenses use multiple elements to achieve the same feat, which is why they get so bulky.
Prior to this latest breakthrough, the SEAS team says they were only able to manufacture metalenses that were "the size of a piece of glitter." By contrast, their latest invention is larger at approximately one centimeter in diameter Bigger, in this case, is better because it makes it more feasible to use the technology in a host of modern applications.

"Gaganyaan" Programme Envisages Two Unmanned And One Manned Flight To Mars

A human mission to Mars has always been the next big dream for space enthusiasts, with space barons like SpaceX CEO Elon Musk, Blue Origins CEO Jeff Bezos and Virgin Galactics founder Sir Richard Branson along with NASA aiming to send humans to deeper space, and eventually Mars, in years to come.
India, which created history nearly five years back with becoming the first country to enter Mars orbit in its maiden attempt with "Mission Mangal", is also looking to send a manned mission to send a manned mission to space by 2022.
India also has ambitions to land a probe on Mars, as its lunar mission Chandrayaan-2 gets ready to drop the Vikram lander on Moon on September 7, 2019.
The country's ambitious "Gaganyaan" programme envisages two unmanned and one manned flight to space.
India's human space mission, which is one of the pet projects of the Prime Minister, is estimated to cost around Rs 10,000 crore and the Indian Space Research Organisation's (ISRO) and Human Space Flight Centre (HSFC) is targeting to send an astronaut to space by 2022.
