A massive carving of a resting cat on the slope of a steep hill was discovered there.
The Nazca Lines are a group of very large geoglyphs made in the soil of the Nazca Desert in southern Peru.
They were created between 500 BCE and 500 CE by people making depressions or shallow incisions in the desert floor, removing pebbles and leaving differently coloured dirt exposed.
There are many figurative designs of animals and plants.
The figures include pelicans (the largest ones sized around 935 feet long), Andean Condors (443 feet), monkeys (360 feet), hummingbirds (165 feet), and spiders (150 feet).
Geometric shapes, such as triangles, trapezoids and spirals, are also found.
Some designs have been associated with astronomical functions as well.
The Lines were declared a World Heritage Site by UNESCO in 1994.
Trial run of Delhi’s buses on Hydrogen-blended CNG (HCNG) launched
The trial run of Delhi’s buses on Hydrogen-blended CNG (HCNG) was recently launched.
Ministry: Ministry of Petroleum & Natural Gas
HCNG is a hydrogen-enriched compressed natural gas (CNG).
In Delhi, instead of physically blending hydrogen with CNG, hydrogen spiked CNG will be produced using compact reforming process patented by Indian Oil Corporation.
H-CNG blends can be produced directly from CNG, bypassing the energy-intensive electrolysis process and high-pressure blending costs.
The flexible and robust process allows the production of H-CNG on-site, in less severe conditions, and under low pressure.
It provides a higher yield H-CNG mixture by up to 4% to 5% compared to CNG’s input quantity.
The cost of H-CNG production by the above process is about 22% cheaper than conventional physical blending.
The Supreme Court had suggested in 2019 to look at hydrogen-run vehicles as a solution for Delhi NCR’s poor air quality
An SC directive in July 2018 had led to Indian Oil Corporation Limited (IOCL) and Indraprastha Gas Limited (IGL) collaborating to put up this first semi-commercial plant.
Mixing hydrogen with CNG physically is a difficult proposition and that is why IOCL came up with the compact reforming process, which reforms CNG and there is no need for mixing.
NASA’s OSIRIS-REx to collect samples from Asteroid Bennu
NASA’s OSIRIS-REx — Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer — spacecraft shall collect samples of dust and pebbles from asteroid Bennu and deliver them back to Earth in 2023
The asteroid was named after an Egyptian deity by a nine-year-old boy from North Carolina in 2013 who won NASA’s “Name that Asteroid” competition.
The asteroid was discovered by a team from the NASA-funded Lincoln Near-Earth Asteroid Research team in 1999.
Bennu is an asteroid located at a distance of about 200 million miles away from the Earth.
Asteroids are rocky objects that orbit the Sun, much smaller than planets.
They are also called minor planets.
Asteroids are divided into three classes.
First, those found in the main asteroid belt between Mars and Jupiter, which is estimated to contain somewhere between 1.1-1.9 million asteroids.
The second group is that of trojans that share an orbit with a larger planet.
NASA reports the presence of Jupiter, Neptune and Mars trojans.
In 2011, they reported an Earth trojan as well.
The third is Near-Earth Asteroids (NEA), which have orbits that pass close by the Earth
Over 1,400 NEA are classified as potentially hazardous asteroids (PHAs).
OSIRIS-REx mission is NASA’s first mission meant to return a sample from the ancient asteroid.
The mission was launched in 2016, it reached its target in 2018 and since then, the spacecraft has been trying to match the velocity of the asteroid.
Scientists study asteroids to look for information about the formation and history of planets and the sun since asteroids were formed at the same time as other objects in the solar system.
Another reason for tracking them is to look for asteroids that might be potentially hazardous.
Aditi Urja Sanch inaugurated
The Union Minister of Science and Technology and Earth Sciences recently inaugurated the Dimethyl ether (DME) fired “Aditi Urja Sanch” unit along with the DME-LPG blended fuel cylinders.
It is a newly designed Burner.
The new design is efficient for both DME and the blend of DME and LPG.
Novel design and flexible air access.
The new nozzle design allows optimum oxygen access for combustion.
The angles at which nozzles are placed maximize the heat transfer area across the utensils.
Optimum flame velocity can be obtained.
The length of the flame (high, low, and medium) can be adjusted by altering the oxygen ingress.
The experiment shows that it increases the heat transfer rate as well.
Dimethyl ether (DME) is an ultra-clean fuel.
CSIR-NCL has developed nation’s first kind of DME pilot plant with 20-24Kg/day capacity.
The conventional LPG burner is not suitable for DME combustion as DME density is different than LPG.
To address this issue, CSIR- NCL’s “Aditi Urja Sanch” was developed.
The new Burner is fully designed and fabricated by NCL for DME, DME -LPG blended mixtures and LPG combustion.
Kavaratti to be commissioned into the Indian Navy
The last of four indigenously built Anti-Submarine Warfare (ASW) stealth corvettes (a small warship) “INS Kavaratti” under Project 28 (Kamorta class) is scheduled to be commissioned into the Indian Navy on 22 October 20.
It is referred to as a potent Stealth ASW Corvette.
It has anti-submarine warfare capability
Indigenously designed by: The Indian Navy’s in-house organisation, Directorate of Naval Design(DND)
Built by: Garden Reach Shipbuilders & Engineers (GRSE), Kolkata
Kavaratti has a state-of-the-art weapons and sensor suite capable of detecting and prosecuting submarines.
The ship also has a credible self defence capability and good endurance for long-range deployments.
Environmental Clearance given to the Kaleshwaram project void
Recently, the National Green Tribunal has ruled that the Environmental Clearance given to the Kaleshwaram project in December 2017 was void.
This was so because the Telangana government subsequently changed the design of the project to increase its capacity.
The petition filed in 2018 stated that while the Kaleshwaram Project was a lift irrigation system, the state government had wrongly claimed, until the grant of environmental clearance (EC), that the project was not for lift irrigation, but only for drinking water supply.
The NGT has now directed that until the Telangana government obtains final forest clearance, it should stop all work except the drinking water component.
The Kaleshwaram Lift Irrigation System is considered to be one of the world’s largest multi-purpose projects.
It is designed to provide water for irrigation and drinking purposes to districts in Telangana, apart from Hyderabad and Secunderabad.
The project starts at the confluence point of Pranahita River and Godavari River.
CSIR Ushered Repurposed Drugs (CuRED)
Recently, Union Health and Science and Technology Minister launched CuRED.
It is a website that gives comprehensive info about the numerous COVID-19 clinical trials that the Council of Scientific & Industrial Research (CSIR) is engaged in partnership with industry, other government departments and ministries.
It provides information about the drugs, diagnostics and devices including the current stage of the trials, partnering institutions and their role in the trials and other details.
