Breaking a space exploration record on New Year’s Eve, NASA first asteroid-sampling mission, OSIRIS-REx, entered into orbit around the Bennu, making it the smallest object ever to be orbited by a spacecraft.

Inching around the asteroid at a snail’s pace, OSIRIS-REx’s first orbit marks a leap for humankind.


Never before has a spacecraft from Earth circled so close to such a small space object – one with barely enough gravity to keep a vehicle in a stable orbit.

The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) arrived at asteroid Bennu on December 3.

The spacecraft, 110 million kilometres away, carried out a single, eight-second burn of its thrusters on Monday.

“The team continued our long string of successes by executing the orbit-insertion maneouvre perfectly,” said Dante Lauretta, OSIRIS-REx Principal Investigator at the University of Arizona, Tucson, US.

“With the navigation campaign coming to an end, we are looking forward to the scientific mapping and sample site selection phase of the mission,” Lauretta added.

“Entering orbit around Bennu is an amazing accomplishment that our team has been planning for years,” Lauretta said.

Now, the spacecraft will circle Bennu about a 1.75 kilometres from its centre, closer than any other spacecraft has come to its celestial object of study.

Previously the closest orbit of a planetary body was in May 2016, when the Rosetta spacecraft orbited about seven kilometres from the centre of the comet 67P/Churyumov-Gerasimenko.

The spacecraft is scheduled to orbit Bennu through mid-February at a leisurely 62 hours per orbit.

The December 31 manoeuvre to place the spacecraft into orbit about Bennu is the first of many exciting navigation activities planned for the mission.

The OSIRIS-REx team will resume science operations in late February.

At that point, the spacecraft will perform a series of close flybys of Bennu for several months to take high-resolution images of every square inch of the asteroid to help select a sampling site.

During the summer of 2020, the spacecraft will briefly touch the surface of Bennu to retrieve a sample.

The OSIRIS-REx mission is scheduled to deliver the sample to Earth in September 2023. (IANS)

Bullying may occur anywhere, at any time, in person or online (cyberbullying), and can take many forms, including verbal, physical, and social.

What Is Bullying?

Bullying is a pattern of recurrent aggressive behavior in which one person (or a group of individuals) in a position of authority intentionally intimidate or abuse another individual to cause bodily or emotional harm to that other. Bullying may take place in either a physical or verbal manner. Bullied individuals, as well as those who bully others, may have long-term repercussions.

Bullying may occur anywhere, at any time, in person or online (cyberbullying), and can take many forms, including verbal, physical, and social. Bullies utilize their position of power — such as physical strength, knowledge of something embarrassing, or popularity — to exert control over or damage other people. Many people assume that bullying occurs solely during childhood; nevertheless, bullying does not necessarily stop after a person reaches the age of adulthood.

Copper earrings

Silver and gold have always been preferred when it comes to wearing jewellery. Right from the times of monarchy in India, wealth and riches have been associated with wearing gold and silver for the various properties they have. Copper is a metal that has always been worn by the poor. It is not a metal that carries a significant association with health or wealth, but wearing at least one article of copper is extremely beneficial for health.

Copper is a reddish-brown metal that cannot be worn on its own. It has to be worn in the form of an alloy to prevent a reaction. Copper oxidizes in air and forms a green layer on it when exposed, much like the Statue of Liberty. Usually, bangles, chains, or rings of copper always have brass and traces of silver in them which helps with stabilizing its reactivity.

Traditional players are very strong in the consumer laptop market.

By Md Waquar Haider

When popular smartphone brands like Xiaomi and realme entered the laptop market in India last year, they were expected to shake the existing giants, specifically under the Rs 50,000 category. However, chip shortage and supply crunch have somewhat dented their plans to make a significant mark to date. According to industry experts, the issue with smartphone makers entering the laptop category is two-fold. The first one is a massive supply crunch in the laptop component market and only big brands are able to get volume and supplies.

The other factor is that the traditional players are very strong in the consumer laptop market. Top 3 players control more than 70 per cent of the market and strong portfolio, distribution, and channel reach as well as brand marketing has helped them massively. "New brands can surely make a dent in the consumer laptop market but are challenged by supply issues right now. Watch out for them in 2022 as and when supply situation eases up," Navkendar Singh, Research Director, Client Devices & IPDS, IDC India told IANS.

Dominated by HP Inc, Lenovo and Dell, the traditional PC market (inclusive of desktops, notebooks, and workstations) in India continued to be robust as the shipments grew by 50.5 per cent year-over-year (YoY) in the second quarter (Q2), according to IDC. Notebook PCs continue to hold more than three-fourth share in the overall category and grew 49.9 per cent YoY in 2Q21, reporting a fourth consecutive quarter with over 2 million units. Desktops also indicated a recovery as shipments grew 52.3 per cent YoY after recording the lowest shipments of the decade in 2Q20.

According to Prabhu Ram, Head, Industry Intelligence Group, CMR, driven by the pandemic and the associated accelerated pivot to remote work, learn and unwind culture, PCs have been witnessing heightened demand. "Despite the current supply chain constraints, PCs are here to stay in the new never normal. In the run-up to the festive season, established PC market leaders will continue to leverage their brand salience and gain market share," Ram told IANS.
