Nokia says it has been tapped by NASA to build the first cellular communications network on the moon.
The Finnish telecommunications equipment maker said Monday its Nokia Bell Labs division will build a 4G communications system to be deployed on a lunar lander to the moon’s surface in late 2022.
NASA is awarding $370 million to 14 companies to provide technology for the Artemis moon-landing program. The program’s aim is to establish a long-term human presence on the moon as a warm-up for missions to Mars.
Nokia released more details of its involvement after an announcement last week by NASA, which said it was giving the company’s U.S. unit $14.1 million for the network. The U.S. space agency is also funding other innovations in cryogenic fluid management, lunar surface innovation, and descent and landing capability.
Nokia’s network will provide critical communications capabilities for tasks astronauts will need to carry out, like remote control of lunar rovers, real-time navigation and high-definition video streaming, the company said.
The equipment includes a base station, antennas and software and is designed to withstand harsh launches and lunar landings and extreme conditions in space.
Nokia is partnering with U.S. company Intuitive Machines, which NASA chose to build a small “hopper lander” that can access lunar craters and carry out high-resolution surveys of the lunar surface over a short distance.
“Reliable, resilient and high-capacity communications networks will be key to supporting sustainable human presence on the lunar surface,” Nokia’s chief technology officer, Marcus Weldon, said.
As an off-shoot of renowned Smartphone manufacturing brand Oppo, OnePlus got a huge reputation worldwide for producing flagship killer phones. Day by day, OnePlus has stepped into the realm of flagship phones. On the 14th of October 2020, the OnePlus has launched its latest flagship innovation OnePlus 8T. Can this Smartphone fulfill the users’ expectations? Read this OnePlus 8T review to know its specs, features, and price in Bangladesh.
OnePlus 8T comes with an easy-to-grip flat display. Its glass built backside with metal frame offers a premium experience. Like the 8 Pro version, 8T’s back panel sports a fingerprint-resistant matte finish, which is an upgrade from the OnePlus 8’s fingerprint-hungry glossy finished back. However, 8T lacks the aesthetics of the 3D curved display we got in the OnePlus 8 and the Pro version. The design of 8T looks quite similar to the budget counterpart Nord model.
The OnePlus 8T bears a fast-responsive in-display fingerprint scanner and face unlock feature. However, the 8T lacks the dust and water-resistant rating feature making the OnePlus fans disappointed! However, OnePlus boasts about applying some kind of sealing techniques that would save this gadget from sudden impacts of water splashes.
On the top-right hand side of 8T’s rear panel, a quad-camera setup is housed on a rectangular platform. This is a noticeable change compared with the middle positioned triple rear camera set up of the ancestor OnePlus 8 and 8 Pro versions. The 8T includes a stereo speaker, but no headphone jack. It has no slot for a microSD card. The fresh flagship Oneplus 8T is found in two amazing color options: Aquamarine Green and Lunar Silver.
OnePlus have won the crown of magnificent displays, and its latest 8T continues this legacy offering a Fluid AMOLED panel with HDR10+ display. Its 6.55-inch sized screen size is both manageable to handle and comfortable to watch the contents. The 8T’s full HD resolution (2400 x 1080pixels, 20:9 ratios, and 402 PPI densities) assures flagship-level visual experience through vivid color pallet, contrast, and details.
What is more? By virtue of a 120Hz refresh rate, the OnePlus 8T features a butter-smooth navigation experience. Once you get used to a phone with such a high refresh rate, the 60Hz displays can no more satisfy you! Its front-screen and back panels are protected by the Corning Gorilla Glass 5. With 678 nits brightness, 8T performs great in direct sunlight which many pricier competitors have failed to offer!
The OnePlus 8T is equipped with Kryo 585 octa-core processor with the utmost 2.84 GHz of clock speed. Though fans were expecting the Qualcomm Snapdragon 865 Plus processor in the OnePlus 8T model, it stagnates at the same old SD 865 SoC! It is a pity that OnePlus has applied the same chipset provided in the ancestor OnePlus 8 model. Maybe it happened due to the cost-cutting reasons. The 8T bears Adreno 650 GPU.
You get the OnPlus 8T in two variants: 8/128GB and 12/256GB. Like the 8 versions, 8T carries the LPDDR 4X RAM. However, the pro version’s LPDDR5 RAM was expected in the latest 8T. Nevertheless, with 3.1 data storage technology, the OnePlus 8T out-wins its ‘8 Pro’ version.
Running on the up-to-date OxygenOS 11, the 8T is blessed with the latest Android 11 OS. 8T’s OS is rich in the top-notch security features and privacy options. Though the latest OxygenOS11 operating system is highly optimized, it feels lightweight, clean, and super fast. One of the most exclusive features of the OxygenOS 11 is the ‘always-on’ display showing diverse notifications as well as versatile clock styles.
The 8T’s SD 865 CPU and powerful RAM would facilitate the smooth operations of heavy-duty apps and software. Furthermore, the intelligent vapor chamber cooling mechanism has been applied in this gadget in order to prevent the heat generation process. The gamers would love playing the latest multiplayer games such as COD, PUBG, Freefire, Asphalt 9, etc on 8T. However, playing demanding games for a long time can make this device a bit warm.
The OnePlus 8T’s quad rear camera series includes a 48MP f/1.7 prime shooter with a 16MP f/2.2 ultra-wide sensor. 8T also has a 5MP f/2.4 macro and a 2MP f/2.4 depth camera. On the front screen, a 16MP selfie camera is provided which we have also seen in the ancestor 8 version. However, the telephoto lens is omitted in the 8T version.
Its 48MP prime rear sensor takes bright and vibrant 12MP photos applying the pixel binning mechanism. Though its images feature enough detailing and greater dynamic range, it can’t capture full 48MP photos. The shots come up with a bit of imposed color tints and smoothing effects. In the portrait-mode photos, the skin tones of the subjects suffer from an over-whitening effect that everyone may not like. However, the portraits still look decent for uploading on social media.
In the low light situations, the night mode can efficiently illuminate and highlight the dark areas besides adding details. This 48MP camera is built with Sony’s IMX586 sensor which we have also seen in the ancestor 7T Pro. Certainly, an upgraded sensor could make the 8T a more lucrative deal!
Its 16MP ultra wide-angle camera features a 123-degree field of view. This sensor is efficient in capturing large groups, extensive structures, and panoramic landscapes. In ample light, this sensor takes average quality images with good detailing. The ultra-wide sensor also works with the night mode feature. However, the image processing performance is not so overwhelming.
8T’s 5MP macro sensor takes good photos but the detailings are less than the ‘8pro’ version’s micro-lens photos. However, using its 2x digital zooming capacity you can see the details. Moreover, you can shoot pleasing monochrome photos with the 8T’s 2MP monochrome camera. However, this sensor feels like a sort of publicity stunt. The provision of a telephoto lens could do better.
On the front side, the OnePlus 8T holds a 16MP f/2.4 selfie camera like its ancestor 8 and the 8 pro versions. 8T takes pretty selfies revealing sharp edges. Like the rear main camera’s portrait photos, the front shooter’s selfie-portraits bear some added hues, and softening effect.
Starting from 1080p@30fps, the rear main camera's utmost video recording capacity reaches 4K@60fps. And its Super Slow Motion mode can capture 720p footage at 480fps/1080p/240fps. The auto-HDR, gyro-EIS, and Nightscape mode can alleviate the quality of video clips. Though OnePlus claims that 8T’s video recording options include the portrait bokeh mode, its effectiveness is questionable. Besides these, the selfie camera can record 1080p videos at 30fps.
The OnePlus 8T is powered up with a 4,500 mAh battery. At the highest 120Hz refresh rate, 8T provides about 5.5 to 6 hours of screen-on-tome (SOT). Certainly, it is good news for the people who tend to use phones for long hours of the day. Lowering the screen’s refresh rate, you can enjoy longer SOT. The OnePlus 8T takes less than 40 minutes to get fully recharged. Credit goes to its dual battery pack and 65W fast charger. However, we have already seen these features in many budget phones like Realme 7 pro. However, the lack of wireless charging facility questions the fat price-tag of the OnePlus 8T once again.
OnePlus 8T's basic variant (8GB/128GB) is unofficially available at BDT 49,990 in Bangladesh. And the top variant (12GB/256GB) costs about BDT 54,990. The price may vary depending upon circumstances.
The new OnePlus flagship Smartphone 8T presents a combination of flagship-level features such as fluid AMOLED panel, full HD resolution, 120Hz display, powerful RAM, adequate storage, etc. However, in the camera section, the 8T seems to lose its flagship title. And, we have found no significant fresh technology in this phone. Most of the 8T features are available in the ancestor OnePlus phones as well as the contemporary competitor phones. Overall, considering the features, the Oneplus 8T phone’s price-tag seems a bit exorbitant.
The drama unfolds Tuesday as the U.S. takes its first crack at collecting asteroid samples for return to Earth, a feat accomplished so far only by Japan.
Brimming with names inspired by Egyptian mythology, the Osiris-Rex mission is looking to bring back at least 2 ounces (60 grams) worth of asteroid Bennu, the biggest otherworldly haul from beyond the moon, reports AP.
The van-sized spacecraft is aiming for the relatively flat middle of a tennis court-sized crater named Nightingale — a spot comparable to a few parking places here on Earth. Boulders as big as buildings loom over the targeted touchdown zone.
“So for some perspective, the next time you park your car in front of your house or in front of a coffee shop and walk inside, think about the challenge of navigating Osiris-Rex into one of these spots from 200 million miles away,” said NASA’s deputy project manager Mike Moreau.
Once it drops out of its half-mile-high (0.75 kilometer-high) orbit around Bennu, the spacecraft will take a deliberate four hours to make it all the way down, to just above the surface.
Then the action cranks up when Osiris-Rex’s 11-foot (3.4-meter) arm reaches out and touches Bennu. Contact should last five to 10 seconds, just long enough to shoot out pressurized nitrogen gas and suck up the churned dirt and gravel. Programmed in advance, the spacecraft will operate autonomously during the unprecedented touch-and-go maneuver. With an 18-minute lag in radio communication each way, ground controllers for spacecraft builder Lockheed Martin near Denver can’t intervene.
If the first attempt doesn’t work, Osiris-Rex can try again. Any collected samples won’t reach Earth until 2023.
While NASA has brought back comet dust and solar wind particles, it’s never attempted to sample one of the nearly 1 million known asteroids lurking in our solar system until now. Japan, meanwhile, expects to get samples from asteroid Ryugu in December — in the milligrams at most — 10 years after bringing back specks from asteroid Itokawa.
Bennu is an asteroid picker’s paradise.
The big, black, roundish, carbon-rich space rock — taller than New York’s Empire State Building — was around when our solar system was forming 4.5 billion years ago. Scientists consider it a time capsule full of pristine building blocks that could help explain how life formed on Earth and possibly elsewhere.
“This is all about understanding our origins,” said the mission’s principal scientist, Dante Lauretta of the University of Arizona.
There also are selfish reasons for getting to know Bennu better.
The solar-orbiting asteroid, which swings by Earth every six years, could take aim at us late in the next century. NASA puts the odds of an impact at 1-in-2,700. The more scientists know about potentially menacing asteroids like Bennu, the safer Earth will be.
When Osiris-Rex blasted off in 2016 on the more than $800 million mission, scientists envisioned sandy stretches at Bennu. So the spacecraft was designed to ingest small pebbles less than an inch (2 centimeters) across.
Scientists were stunned to find massive rocks and chunky gravel all over the place when the spacecraft arrived in 2018. And pebbles were occasionally seen shooting off the asteroid, falling back and sometimes ricocheting off again in a cosmic game of ping-pong.
With so much rough terrain, engineers scrambled to aim for a tighter spot than originally anticipated. Nightingale Crater, the prime target, appears to have the biggest abundance of fine grains, but boulders still abound, including one dubbed Mount Doom.
Then COVID-19 struck.
The team fell behind and bumped the second and final touch-and-go dress rehearsal for the spacecraft to August. That pushed the sample grab to October.
“Returning a sample is hard,” said NASA’s science mission chief, Thomas Zurbuchen. “The COVID made it even harder.”
Osiris-Rex has three bottles of nitrogen gas, which means it can touch down three times — no more.
The spacecraft automatically will back away if it encounters unexpected hazards like big rocks that could cause it to tip over. And there’s a chance it will touch down safely, but fail to collect enough rubble.
In either case, the spacecraft would return to orbit around Bennu and try again in January at another location.
With the first try finally here, Lauretta is worried, nervous, excited “and confident we have done everything possible to ensure a safe sampling.”
The iPhone 12 has just been announced which means another year for mobile phone aficionados to rally behind Apple’s latest technological breakthroughs. Certain leaps like camera quality and processing speed are always appreciated, but there are a few basic features that have been put on the wayside over the years. We understand that Apple’s minimalist goals promote a more user-friendly experience, but we’d like to walk down memory lane and reminisce over some of the older features we miss from previous iPhones.
Having a Charger and Earphones WITH an IPHONE
Let’s address the elephant in the room from iPhone 12’s reveal. It’s safe to assume that no one was expecting Apple to throw a curveball like this in their latest announcement. Regardless of brand, a charger and earphones are uncompromising staples every consumer would expect when picking up a brand-new phone, but the iPhone 12 has changed this status quo - and we worry a day might come when other phone companies decide to follow suit. We understand their attempt to reduce the carbon footprint on a massive scale; it is admirable, but at what cost? Apple acknowledged that with over 2 billion existing chargers out in the wild (excluding external brands) and over 700 million earphones, there was too much wasteful manufacturing from a logistics standpoint. It’s hard to argue with these eye-opening figures but an alternative over a deletion would be nice.
Going wireless can be seen more as a preference than technological advancement. Sometimes, the wired alternative gives us a chance to use certain headphones that offer the perfect sound we’re looking for; and other times, it’s just easier on the wallet. Regardless, having a headphone jack gave us an extra option that we now do not have. The new adapters are an acceptable replacement, but the cable quality can vary between working wonders for almost a year to fizzling out in just a couple of months. The plus side is that replacing the jack with an additional speaker did make sound distribution a lot better, but some may argue that it wasn’t worth the sacrifice. On top of that, we’ve had to say our goodbyes to the good old days of charging our phones while listening to music without an adaptor. Granted, it has been a few years since iPhone users have had to go jack-less, but that doesn’t mean that this feature will be sorely missed.
Having the magic home button on the iPhone removed has in no way made the iPhone series less desirable, but we’d be lying if we said that not a single person in the community wanted it back. The introduction of facial recognition on the debut of the iPhone X was a game-changer and definitely boasted Apple’s proficiency in innovative technology (let’s pretend Samsung doesn’t exist for a moment). Your phone being able to only recognise your face is certainly by leaps and bounds more secure than a fingerprint scanner on a button; but we could make a case for preferential differences for unlocking speed and convenience. Apple did implement a setting that allowed the user to freely place a digital home button anywhere on the screen, but it isn’t quite the same. Given the current global situation, masks are probably the bane of everyone who uses facial recognition at the moment.
Environment, Forest and Climate Change Ministry’s Secretary Md. Ziaul Hasan termed the country’s electronics giant Walton’s factory as very clean, hygienic and environment-friendly.
At every stage of production, Walton’s engineers have been successfully using latest and environment-friendly technologies and machineries, he said adding: “I am very pleased witnessing the compliance maintained and environment-friendly Walton factory."
The environment secretary came up with the remarks after visiting Walton factory at Chandra in Gazipur on Saturday (October 17, 2020).
While visiting Walton AC Manufacturing Unit, the environment secretary unveiled a new model of Walton’s air condition named ‘Inverna.’ Worldwide recognized environment-friendly R410a refrigerant has been used in the Walton’s new model of AC.
During his visit, he also said, Walton is a great achievement and also a pride for Bangladesh. Walton reduced the country’s import dependency. After meeting the local demands, Walton is earning foreign currencies from export.
As per the Montreal protocol, Walton in association with Environment Division and UNDP has been implementing the phase-out projects of hazardous substances, he noted.
Ziaul Hasan also praised on the prevailing good relationship between workers and owners at Walton factory. For workers, he said, hygienic dinning and accommodation facilities have been available.
In fact, Walton established a compliance and environment-friendly factory in Bangladesh, he said adding that Walton made an example in setting up a compliance, hygienic and environment-friendly factory, saying it the environment secretary added, Walton’s such initiative could be followed by the country’s other private sectors.
Along with the environment secretary, Additional Secretary of Environment, Forest and Climate Change Ministry Mahmud Hasan, Senior Assistant Director Shahidul Hoque Patwary and Assistant Director of Department of Environment in Gazipur Ashraf Uddin also visited Walton factory.
Environment Ministry’s Additional Secretary Mahmud Hasan said, Today’s visit at Walton factory has enriched our knowledge on the establishment of a eco-friendly factory. Like Walton, other private industries should come forward in the development and progress of Bangladesh as well as preservation of environment.
Earlier on Saturday morning, Walton Hi-Tech Industries Limited Directors SM Mahbubul Alam and Nishat Tasnim Shuchi welcomed the guests with flower bouquets.
