চলতি বছরেই সংযুক্ত আরব আমিরাতের প্রথম মহাকাশযান ‘হোপ’ মঙ্গলের উদ্দেশ্যে যাত্রা করবে। সংযুক্ত আরব আমিরাতের জন্য এটিই প্রথম মহাকাশ মিশন।


তাদের মহাকাশের স্বপ্নকে বাস্তবায়িত করতে যুক্তরাষ্ট্র সহায়তা করছে। মহাকাশযানটির নকশা ও নির্মাণ কাজ দুই দেশের প্রকৌশলীরা মিলিতভাবে সম্পন্ন করে।

সংযুক্ত আরব আমিরাতের পক্ষ থেকে বলা হয়েছে, তারা চাইলে নিজস্ব প্রযুক্তিতে রকেট নির্মাণ করে মহাকাশে পাঠাতে পারতো। কিন্তু এতে অনেকসময় ব্যয় হতো। অল্প সময়ের মধ্যে তারা মহাকাশে নিজেদের অবস্থান শক্তিশালী করতে চায়। এজন্য অন্য দেশের সঙ্গে অংশীদারিত্বে গিয়েছে তারা। তবে অংশীদারিত্ব হলেও উৎক্ষেপণের পর দুবাই থেকেই সব কাজ করা হবে।


 
মহাকাশ গবেষণায় দেশটির সংযুক্তি ভবিষ্যৎ মহাকাশ গবেষণার জন্য বেশ বড় সুখবর। দেশটি হোপ মিশনে খুব বেশি ব্যয় করছে না। এজন্য তাদের পক্ষ থেকে এটিকে ‘টাইট বাজেট’ প্রকল্প বলা হচ্ছে।

জানা গেছে, মঙ্গলের কক্ষপথ থেকে গ্রহটিকে পর্যবেক্ষণ করে তথ্য পাঠাবে হোপ।

নিজস্ব প্রতিবেদন : একদিকে যেমন সবকিছু ডিজিটালাইজড হচ্ছে, ঠিক তেমনই পাল্লা দিয়ে বাড়ছে সাইবার ক্রাইমও। আর এই সাইবার জালিয়াতির দুনিয়ায় সফ্ট টার্গেট হচ্ছে এটিএম কার্ড। সম্প্রতি, কলকাতা ও দিল্লির বেশকিছু ATM-এ কার্ড জালিয়াতির ঘটনা সামনে আসে। একের পর এক অ্যাকাউন্ট থেকে উধাও হয়ে যায় লাখ লাখ টাকা। ATM কার্ড জালিয়াতির হাত থেকে বাঁচতে তাই মেনে চলুন কিছু নিয়ম।

বিপদ এড়াতে সবসময় খেয়াল রাখুন এগুলো-

* নির্দিষ্ট সময়ের পর পর এটিএম কার্ডের পিন পরিবর্তন করুন।


* কার্ডে পিন নম্বর লিখে রাখবেন না, কাউকে কার্ড দেবেন না। এমনকি নিজেও পিন নম্বর কাউকে বলবেন না।

* আপনি যখন এটিএমের ভিতরে থাকবেন, তখন অন্য় কাউকে প্রবেশ করতে দেবেন না।

* এটিএম মেশিনে পিন দেওয়ার সময় হাত দিয়ে আড়াল করে পিন দিন। যাতে অন্য় কারোর নজরে না পড়ে।

* এটিএম থেকে টাকা তোলার পর যে স্লিপ আসে তা কাউন্টারে ফেলে আসবেন না।

* এটিএমের স্ক্রিন যতক্ষন না পুরনো অবস্থায় ফিরে আসছে, ততক্ষণ পর্যন্ত অপেক্ষা করবেন।

* নতুন কার্ড নেওয়ার পর পুরনো কার্ড পুরোপুরি নষ্ট করে ফেলুন।

Uber and Lyft have weathered criticism about pollution and traffic congestion for years, but it’s been difficult to get an exact gauge about how much ride-hailing contributes to daily emissions. A new study released today claims to have a more precise answer to this question.

According to the Union of Concerned Scientists, ride-hailing trips today result in an estimated 69 percent more climate pollution on average than the trips they displace. In cities, ride-hailing trips typically displace low-carbon trips, such as public transportation, biking, or walking. Uber and Lyft could reduce these emissions with a more concerted effort to electrify its fleet of vehicles or by incentivizing customers to take pooled rides, the group recommends.

“TRIPS MUST BE POOLED AND ELECTRIC [AND] DISPLACE SINGLE-OCCUPANCY CAR TRIPS MORE OFTEN”
“However, those strategies alone will address neither the increases in vehicle miles traveled nor rising congestion concerns,” the report says. “For ride-hailing to contribute to better climate and congestion outcomes, trips must be pooled and electric, displace single-occupancy car trips more often, and encourage low-emissions modes such as mass transit, biking, and walking.”

It’s a tall order, but both Uber and Lyft have shown a willingness to reduce their carbon footprint. So far, their methods include introducing bike- and scooter-sharing services, integrated public transportation scheduling and ticketing into their respective apps, and incentive programs to get drivers to switch to electric cars.

Lyft rolled out a multimillion-dollar investment to become a completely carbon-neutral transportation service through the purchase of carbon offsets, while Uber explored providing cash incentives to some North America-based drivers who use electric vehicles.


But despite these efforts, the vast majority of trips that take place on both Uber and Lyft’s platforms are in gas-burning vehicles. The companies have tried promoting pooled rides, but customers have shown a reluctance to share their trips. Their efforts to better connect to mass transit have been slow and piecemeal at best. And their bike and scooter sharing services are subject to local regulations and market conditions, and as such can be unreliable.

A more systemic effort to address climate pollution has yet to emerge from either Uber or Lyft. And the solutions they’ve proposed so far are unlikely to address the core problem with ride-hailing: it is often more convenient and less expensive than other, less-polluting transportation options.

Update February 25, 11:39AM ET: “We want Uber to be a part of the solution to address climate change by working with cities to help create a low carbon transportation future,” a spokesperson said. “To unlock the opportunities we have to reduce emissions, we will continue to invest in products and advocate for policies that reduce car ownership, promote more pooled trips and support greater adoption of bikes, scooters, green vehicles and the use of public transit.”

Lyft, meanwhile, dismissed the report as “misleading.”

“This report, like many before it, makes misleading claims about rideshare,” a spokesperson said. “Lyft encourages the use of shared rides, was the first rideshare company to put public transit information into our app, and last year, made one of the largest single deployments of electric vehicles in the nation. We are eager to continue this work in partnership with cities, to advance shared, sustainable transportation.”

ICT / Star Wars: The High Republic is Disney's new Star Wars saga
« on: Yesterday at 11:31:07 PM »
In December The Rise of Skywalker ended the Star Wars sequel trilogy. But fear not, Jedis and Sith Lords, Disney and Lucasfilm have plenty of Star Wars in the pipeline for you. On Monday the two companies unveiled Star Wars: The High Republic, formerly known as Project Luminous, which combines novels, children's books and comics to tell one interconnected story.

The High Republic saga is set 200 years before The Phantom Menace, the first prequel film. That puts it at about 260 years before the original Star Wars flick. At this stage in the Star Wars universe, the Jedi Order still has the Galactic Empire very much under control. No Machiavellian, secretly Sith politicians around here, no sir.

According to Michael Siglain, director of Lucasfilm Publishing, this quote from Obi-Wan Kenobi is the inspiration for the new saga: "For over a thousand generations the Jedi knights were the guardians of peace and justice."

"[It's] a line that we've been hearing since 1977, and we thought, 'what does that look like?'" Siglain explains in a teaser trailer for The High Republic. The teaser also features creators on how they envisage the Jedi of this era as "the Jedi Knights of the Round Table" -- which is to say the Jedi Order is at the peak of its heroism and badassery.


But of course, calamity will strike and heroes will be tested. The threat emerges from the Nihil, imagined as "space vikings" who live on the fringe of the Galactic Empire, according to the creators. The Jedi won't be the only stars, though, as new smugglers, scoundrels and bounty hunters will also see time in the spotlight.

Phase one of The High Republic debuts in August at the Star Wars Celebration Anaheim convention, and will feature five releases: young adult novel Into the Dark, middle grade novel A Test of Courage, comic book series The High Republic Adventures, another comic book series (this one from Marvel) called simply The High Republic, and finally a novel called The Light of the Jedi.

Nasa has been able to confirm that Mars is seismically active after its Insight spacecraft was able to detect two quakes large enough to be tracked back to their source.

First landing in November 2018 in the Elysium Planitia region, Insight (pictured above) detected over 100 “Marsquakes” in its first year on the planet. However, there was some debate amongst scientists as to whether the vibrations detected were legitimate seismic activity or just Martian wind rattling its instruments.

Dr Bruce Barnerdt, InSight principal investigator and lead author on one of the studies, said: “We finally have, for the first time, established that Mars is a seismically active planet.”

The first so-called “Marsquake” was recorded by InSight’s onboard sensors in April 2019. Since then, it has detected more than 450 quivers, much smaller than anything that would be felt on Earth.

Two of the quakes were found to emanate from a geologically active area known as Cerberus Fossae, around 1,000 miles east of Elysium Planitia.

The finding is significant as the quakes are thought to be created by the cooling and subsequent shrinking of the planet, alongside general tectonic plate shifting like we have on Earth.

The Martian seismic activity recorded by the lander’s seismometer - a ground-motion detection sensor - was found to be greater than that of the Moon, but less than that of Earth.


“As the planet cools, it contracts and then the brittle outer layers have to fracture in order to sort of maintain themselves on the surface. That’s kind of the long-term source of stresses,” said planetary geophysicist and mission principal investigator Bruce Banerdt.

The team believes that understanding more about the seismic activity of planets other than Earth could reveal clues about how the Solar System formed.

Dr Domenico Giardini, of ETH Zurich in Switzerland and lead author on one of the studies, added: “Marsquakes have characteristics already observed on the Moon during the Apollo era, with a long signal duration (10 to 20 minutes) due to the scattering properties of the Martian crust.”

The researchers devised a magnitude scale tailored to Mars, but similar to the one used for earthquakes. The strongest of the quakes were a little less than magnitude 4, meaning they would be felt on the surface perhaps dozens of miles from the epicenter but probably would not do much damage.

Evidence of dust devils, which are whirls of Martian soil whipped up by the wind that spin like a tornado at nearly 60mph, were observed a month after InSight touched down on Mars.

The £633 million Nasa mission is expected to continue for another year.

In June, Nasa’s Curiosity rover discovered the largest amount of methane measured during its near seven-year mission, a potential sign of life after recent doubts about how much methane the planet really produces.

The attorney general of the US state of New Mexico is suing Google, accusing the company of illegally collecting the personal data of school children.

The tech giant is alleged to have collected data on which websites pupils visited, passwords, videos watched, contact lists, and other information.

The data was allegedly gathered from Google's Chromebook laptops and G Suite for Education programme.

Google disputes the claim, with a spokesman calling it "factually wrong".

Google Chromebooks and the G Suite for Education - which includes Gmail, Calendar, Drive, Docs and others - are offered for free to more than 60% of students in New Mexico, according to the lawsuit.

Attorney General Hector Balderas said Google had failed to get parental consent from children under 13 and collected their data for commercial purposes, in violation of the Children's Online Privacy Protection Act.

"Student safety should be the number one priority of any company providing services to our children, particularly in schools," Mr Balderas said in a statement. "Tracking student data without parental consent is not only illegal, it is dangerous."

"Google should be telling parents that they're going to stalk and track these children, and under the guise of education," he added, according to KRQU News in Albuquerque.

The lawsuit says that more than 80m teachers and students in the US use Google's education platform and tools.

Jose Castaneda, a spokesman for Google, said their programme "allows schools to control account access and requires that schools obtain parental consent when necessary".

"We do not use personal information from users in primary and secondary schools to target ads," his statement added.

    YouTube fined over using kids' data to target ads

The attorney general told US media that he had contacted school districts across the state to assure them that there was no imminent threat in continuing to use Google products.

Last year Google reached a $170m (£130m) settlement with the Federal Trade Commission over allegations that it illegally harvested personal data from children on YouTube.
