Washington, Feb 21: NASA's Jet Propulsion Laboratory will provide daily weather reports for Mars, thanks to the Red Planet's newest robotic resident, InSight, mission scientists announced Thursday.

"The InSight lander is close to the Martian equator -- just north of the equator -- so it is experiencing Martian winter," said Don Banfield, the mission's lead for the lander's Auxiliary Payload Subsystem (APSS).

APSS is a suite of meteorological sensors on the lander's deck that also helps with quake detection.

"For our mission, APSS will help us filter out noise in our data and know when we're seeing a Mars quake and when we aren't," said Banfield, a principal research scientist at Cornell University in the US.

"But by operating continuously, we'll also see a more detailed view of the weather than most surface missions, which usually collect data for just a few hours at a time," Banfield said in a statement.

Currently, Mars' northern hemisphere sits in winter -- the stormy season, researchers said.

"Since the lander is close to the equator, I did not think we would see any evidence of the storms that are 60-degrees north latitude, but we are already seeing evidence of the high and low pressure-signal waves that create weather on Mars," Banfield said.

"We can see those waves all the way down near the equator, as the waves are big enough that they have a signature. That was a surprise," he said in a statement.

The pressure signals oscillate every 2.5 sols (the name for days on Mars), and the waves are easier to predict as opposed to how pressure waves behave on Earth. One sol is about 24 hours, 39 minutes long.

"High and low pressure is indicative of the weather systems," Banfield said.

"Compared to Mars, Earth is pretty chaotic. Mars has a nearly perfect, smooth sinusoidal (up and down) waves -- it is a very regular seesaw guided by a metronome on Mars. On Earth, the pressure is guided by a hyperactive child," he said.

Mission scientists said the coldest temperatures -- as cold as minus 59 degrees Celsius -- occur at around 5 am local time. The warmest temperatures have been minus five degrees Celsius.

When the sun heats up the Martian surface, scientists have observed strong convective overturning.

"Think of a pot of water boiling -- the water is overturning vigorously. That happens on Mars, too," Banfield said.

"The atmosphere near the ground bubbles up like a buoyant plume of air. It happens on Earth, too, but you don't feel it as much. On Mars it happens with a lot more vigour," he said.

In another surprise, mission scientists are observing many "dust devils" -- those ghostly, low-pressure, tornado-like whirls of Martian soil.

"They spin at nearly 96 kilometres per hour. They do shake the lander, and we have seen a lot of that. They even tilt the ground, because we have such a sensitive seismometer," Banfield said.

"On Earth, the desert's dust devils would be likely 15 metres across and almost a kilometer tall. On Mars, they can be five to 10 kilometers tall. Big ones are 100 metres or more in diameter," he said.

The InSight craft landed on Mars in late November and is preparing to monitor the geologic interior of the planet.

Claiming that e-commerce giants like Amazon import as much as 80 per cent of the items sold on their platforms, small manufacturers' body has said that their business models do not benefit local industry and are creating jobs of delivery boys only.

"Neither manufacturers nor traders are getting any benefit from the business models of Amazon and Flipkart because they largely import their products from China and Korea and sell here. Nearly 80 per cent of their products are imported," said Anil Bhardwaj, Secretary General, Federation of Indian Micro and Small & Medium Enterprises (FISME).

Bhardwaj said that the global e-commerce players generally source and sell products through their own preferred suppliers and as a result a large number of local manufacturers and traders get crowded out.

He listed out deep discounting and buying products from preferred companies as unfair practices.

"Even if they buy products from local suppliers the commission charged is very high," Bhardwaj said adding that the issues related to unfair practices have been raised with Commerce Ministry on multiple occasions.

FISME maintains that the technology-driven retail is way forward and one cannot be oblivious of the benefits it brings to consumers but at the same time the local industry can also not be ignored given its role in job creation.

"If both traders and local manufacturers are crowded out then how would the local industry survive and employment be generated?" asked Bhardwaj.

As Amazon Founder and CEO Jeff Bezos is currently on his three-day visit to India, the local traders are up in arms against the "unfair" trade practices of the tech giant. Delhi-based Confederation of All India Traders (CAIT) has launched a countrywide protest against the company and has organised protests across 300 cities.

In a setback to Amazon and Walmart-backed Flipkart, the fair market watchdog Competition Commission of India (CCI) has ordered probe into the business operations of both the companies on multiple counts including deep-discounts and exclusive tie-up with preferred sellers.

"For the first time some concrete step has been taken against Amazon and Flipkart who are continuously violating the FDI policy in indulging in a vicious racket of controlling and monopolising not only the e-commerce but even the retail trade as well," CAIT National Secretary General Praveen Khandelwal said after the CCI order.

New Delhi, Jul 18: India's national cybersecurity agency CERT-in, has warned people of credit card skimming spreading across the world through e-commerce platforms.

Attackers are typically targeting e-commerce sites because of their wide presence, popularity and the environment LAMP (Linux, Apache, MySQL, and PHP), the Computer Emergency Response Team (CERT-In) said in a notice on Thursday.

Recently, attackers targeted sites which were hosted on Microsoft's IIS server running with the ASP.NET web application framework, it said.

Some of the sites affected by the attack were found to be running ASP.NET version 4.0.30319, which is no longer officially supported by Microsoft and may contain multiple vulnerabilities, CERT-In said.

The notice also included a list of best practices for website developers including the use of the latest version of ASP.NET web framework, IIS web server and database server.

The advisory is based on research by Malwarebytes which found that this skimming campaign likely began sometime in April this year.

Credit card skimming has become a popular activity for cybercriminals over the past few years, and the increase in online shopping during the pandemic means additional business for them, too, Malwarebytes said in a blog post, adding that attackers do not need to limit themselves to the most popular e-commerce platforms.

Researchers from global cybersecurity and anti-virus brand Kaspersky had warned in December last year that more cybercriminal groups will target online payment processing systems in 2020. 

It said that over the past couple of years, so-called JS-skimming (the method of stealing of payment card data from online stores), has gained immense popularity among attackers. 

Kaspersky researchers in their report said they are currently aware of at least 10 different actors involved in these type of attacks.

Their number will continue to grow during the next year, the report said, adding that the most dangerous attacks will be on companies that provide services such as e-commerce as-a-service, which will lead to the compromise of thousands of companies.

In the wake of the gas leak at a factory in Visakhapatnam, the National Disaster Management Authority (NDMA) has issued detailed guidelines for restarting industries after the lockdown and the precautions to be taken for the safety of the plants as well as the workers.

In a communication to all states and union territories, the NDMA said due to several weeks of lockdown and the closure of industrial units, it is possible that some of the operators might not have followed the established standard operating procedures.

As a result, some of the manufacturing facilities, pipelines, valves may have residual chemicals, which may pose risk. The same is true for the storage facilities with hazardous chemicals and flammable materials, it said.

The NDMA guidelines said while restarting a unit, the first week should be considered as the trial or test run period after ensuring all safety protocols.

Companies should not try to achieve high production targets. There should be 24-hour sanitisation of the factory premises, it said.

The factories need to maintain a sanitisation routine every two-three hours especially in the common areas that include lunch rooms and common tables which will have to be wiped clean with disinfectants after every single use, it added.

For accommodation, the NDMA said, sanitisation needs to be performed regularly to ensure worker safety and reduce the spread of contamination.

To minimise the risk, it is important that employees who work on specific equipment are sensitised and made aware of the need to identify abnormalities like strange sounds or smell, exposed wires, vibrations, leaks, smoke, abnormal wobbling, irregular grinding or other potentially hazardous signs which indicate the need for immediate maintenance or if required shutdown, it said.

At least 11 people lost their lives and about 1,000 others were exposed to a gas leak at a factory in Andhra Pradesh''s Visakhapatnam on May 7.

The incident took place after it restarted operations when the government allowed industrial activities in certain sectors following several weeks of lockdown.

The lockdown was first announced by Prime Minister Narendra Modi on March 24 for 21 days in a bid to combat the coronavirus threat. The lockdown was then extended till May 3 and again till May 17.
