A bird’s-eye view of farm fires in Haryana, Punjab since 2016

Published

on

Farm fires remain as spread out as before in Punjab and Haryana, but with a gradual reduction in numbers over the last five years, barring 2020, data show.

Satellites detected nearly one lakh fire counts in 2016 in October and November, more than 40 per cent than 2015.

From then on, the counts came down every year till 2020. The number of farm fires last year was 20 per cent lower than 2016, but 60 per cent higher than 2019.

LESS IN NUMBERS, BUT EXTENSIVE IN AREA

The year 2017 recorded a big drop of 32 per cent in stubble burning across Haryana and Punjab, followed by 24 per cent reduction in 2019, an analysis by India Today’s Data Intelligence Unit shows.

That said, stubble-burning events are extensively spread in Haryana and Punjab despite the announcement of Rs. 2,500 an acre bonus for small and marginal farms rejecting the practice. Additionally, Punjab offers incentives to industries for buying stubble.

According to data obtained from NASA satellites, the peak has been recorded in the month of November, especially its first week, for at least the last six years.

The number of stubble burning cases in the first week of November 2016 alone stood at at 34,910, which was almost 77 per cent higher than the previous year. But the counts declined by 60 per cent in the same period of 2017.

However, the stubble-burning number changes every alternate year in the peak period of November, the DIU analysis revealed. In 2020, for instance, fire counts spurt by 60 per cent in the first week of November. In 2021 though, the cases dropped by nearly two per cent compared to the year ago.

FARM FIRES IN 2021

 

Considering the number of farm fires in the first week of November, the year 2021 so far ranked third with 27,941 stubble burning events after 2016 and 2020.

If the declining trend holds firm, the two states may end up with fewer cases of farm fires in October-November this year.

Punjab, Haryana, and Uttar Pradesh follow this practice to clear the fields for sowing winter crops from the last week of September to November.

There is brief window of two to three weeks between harvesting paddy and sowing the next crop.

The burning of residue depends on weather and other factors. The phenomenon in a particular period can, therefore, be recorded better through a comparison of total fire events during October and November than through day-to-day incidents.

According to reliable estimates, Punjab alone produces around 200 lakh tonnes paddy stubble. Haryana produces around 70 lakh tonnes of paddy residue every year.

According to scientists, recent discoveries about an exoplanet made by NASA’s James Webb telescope could change the gam.

Published

on

The exoplanet, known as Bocaparins, was found by NASA’s James Webb Telescope in August of this year. It is a planet outside of our solar system that is 700 light years from Earth. The exoplanet is almost as big as Saturn and much bigger than Earth. But this exoplanet is special because it is 8 times closer to its star than Mercury is to the Sun, making it a very near relative. Around 871 degrees Celsius of heat are produced by the star at the atmosphere’s surface.

Because of this, scientists have started to refer to it as the “Hot Saturn,” and the heat makes the gases that escape into its skies exist only as solitary molecules or in molecular form. In other words, its atmosphere is filled with a variety of gases, including mercury, sulphur, and many more. This has produced an incredibly precise chemical image that gives researchers the opportunity to examine each one separately, including any photochemistry brought on by the host star’s closeness.

According to researchers, this is the first time they have observed photochemistry in action. The ozone layer on Earth is produced in a similar way. Our ozone layer is a product of heat and sunshine working together. This, in their opinion, marks the start of a deeper knowledge of the atmospheres of exoplanets.

CRS-26 mission delayed until November 26 by NASA and SpaceX

Published

on

The National Aeronautics and Space Administration (NASA) and SpaceX resupply mission for the International Space Station has been pushed back to November 26. Weather issues caused the CRS-26 mission, which was scheduled for November 22, to be postponed. This mission marks SpaceX, Elon Musk’s space company, 26th commercial resupply mission.

The agency now plans to debut on November 26 at 2:20 PM ET. The Kennedy Space Center in Florida’s Launch Complex 39A will serve as the spacecraft’s launch pad. The mission was already delayed from November 18 to November 22 because the Dragon spacecraft had a coolant leak.

7,700 pounds of supplies, machinery, and other scientific experiments will be carried by SpaceX’s Dragon spaceship. The Harmony module of the International Space Station will be reached by the spaceship on its own. The next two Roll Out Solar Arrays for the International Space Station are part of the cargo (iROSAs). The scientific laboratory on board the power is anticipated to greatly increase thanks to the arrays.

Four CubeSats from the NASA Educational Launch of Nanosatellites, or ELaNa, programme are also included. Among these is Measurement of Actuator Response in Orbit (MARIO), which will add telescopes to an existing CubeSat, Research and Education Vehicle for Evaluating Radio Broadcasts (TJREVERB), developed by high school students to test the strength of iridium radio signals, Scintillation Prediction Observation Research Task (SPORT), a joint Brazilian-American scientific investigation into the formation of plasma bubbles, and petiSAT, which will examine the impact of plasma bubbles on communication signals, GPS, and radar signals

After dropping off the payload, the Dragon spacecraft will return to the planet in a controlled fall with the reusable Falcon 9 payload.

The Arecibo Observatory will once more collapse, according to the National Science Foundation

Published

on

The breakdown of the world’s most remarkable radar and radio telescope didn’t kill the science at the Arecibo Observatory, yet the Public Science Establishment (NSF) may.

Puerto Rico’s Arecibo Observatory started seeing in 1963 and gathering crucial information for three distinct kinds of science – until December 2020 when it fell after two supporting links fizzled. In October 2022, NSF, which possesses the site, reported its choice to supplant the widely acclaimed logical foundation with another training community and simply toss pocket cash at it. Albeit the ongoing financial plan proposed by NSF increments by almost 20%, NSF has no designs to restore the telescope so Arecibo can keep on assuming a significant and unmistakable part in motivating science and researchers concentrate in Puerto Rico.

With this choice, the NSF avoided the majority of what Congress requested from them in Segment 10365 of the CHIPS Act: “to investigate chances to reinforce and extend the job of the Arecibo Observatory in Puerto Rico through reception of the Arecibo Observatory in Puerto Rico.” instructive projects, mindfulness and variety, and future examination, capacities and innovation at the site” . Right now, the US has generally lost its reality administrative role in environmental science, radar cosmology, and radio stargazing. Every one of these sciences straightforwardly affects our future as a country. Without a trace of another Arecibo observatory, specialists have needed to group perceptions from different offices, however very little can somewhat supplant Arecibo’s capacities. The observatory has given unrivaled and profoundly point by point planning and following of close Earth space rocks of expanding interest; air and geospatial perceptions critical to recording environmental change and the super climate it causes; and definite radar perspective on planets and moons for future investigation.

The Observatory’s one of a kind capacities were obvious even days after the NSF’s foolish choice, declared in October, when reports of Arecibo researcher Sean Marshall’s sightings on the asset The way of the space rock Phaethon overwhelmed the press on October 1. 17. His discoveries will educate the send off regarding another shuttle, as well as add as far as anyone is concerned of the likely danger. As per NASA, there are 2,000 “possibly risky” close Earth space rocks. Arecibo assumed a significant part in the investigation of a large number of them.

Researchers gauge that reconstructing another manifestation of the Observatory with new innovations and capacities will cost about $454 million. (For correlation, NASA has spent more than $10 billion on the James Webb Space Telescope.) The observatory just necessities about $12 million every year to work, a modest number contrasted with space science. NSF is giving not exactly a portion of that sum, or $5 million north of five years, to Arecibo’s Middle for STEM Training and Exploration, in addition to extra upkeep reserves. Americans and our regulative delegates from all ideological groups concur that space research is significant. Arecibo’s significance to our public future is perfect to such an extent that it has been explicitly perceived in the CHIPS Act. Arecibo Observatory’s record is amazing, both in the logical and instructive fields. The restoration of quite possibly of the best telescope on earth ought to be inside the span of the most extravagant country on the planet.
