Fuel leak ruins NASA's 2nd shot at launching moon rocket
NASA’s new moon rocket sprang another dangerous fuel leak Saturday, forcing launch controllers to call off their second attempt to send a crew capsule into lunar orbit with test dummies.
The first attempt earlier in the week was also marred by escaping hydrogen, but those leaks were elsewhere on the 322-foot (98-meter) rocket, the most powerful ever built by NASA.
Launch director Charlie Blackwell-Thompson and her team tried to plug Saturday’s leak the way they did the last time: stopping and restarting the flow of super-cold liquid hydrogen in hopes of removing the gap around a seal in the supply line. They tried that twice, in fact, and also flushed helium through the line. But the leak persisted.
Blackwell-Thompson finally halted the countdown after three to four hours of futile effort.
THIS IS A BREAKING NEWS UPDATE. AP’s earlier story follows below.
CAPE CANAVERAL, Fla. (AP) — NASA's new moon rocket sprang another hazardous leak Saturday, as the launch team began fueling it for liftoff on a test flight that must go well before astronauts climb aboard.
For the second time this week, the launch team began loading nearly 1 million gallons of fuel into the 322-foot (98-meter) rocket, the most powerful ever built by NASA. Monday’s attempt was halted by a bad engine sensor and leaking fuel.
As the sun rose, an over-pressure alarm sounded and the tanking operation was briefly halted, but no damage occurred and the effort resumed. But minutes later, hydrogen fuel began leaking from the engine section at the bottom of the rocket. NASA halted the operation, while engineers scrambled to plug what was believed to be a gap around a seal in the supply line.
The countdown clocks continued ticking toward an afternoon liftoff; NASA had two hours Saturday to get the rocket off.
NASA wants to send the crew capsule atop the rocket around the moon, pushing it to the limit before astronauts get on the next flight. If the five-week demo with test dummies succeeds, astronauts could fly around the moon in 2024 and land on it in 2025. People last walked on the moon 50 years ago.
Forecasters expected generally favorable weather at Kennedy Space Center, especially toward the end of the two-hour afternoon launch window.
On Monday, hydrogen fuel escaped from elsewhere in the rocket. Technicians tightened up the fittings over the past week, but launch director Charlie Blackwell-Thompson stressed that she wouldn't know whether everything was tight until Saturday's fueling.

Even more of a problem on Monday, a sensor indicated one of the rocket's four engines was too warm, but engineers later verified it actually was cold enough. The launch team planned to ignore the faulty sensor this time around and rely on other instruments to ensure each main engine was properly chilled.
Before igniting, the main engines need to be as frigid as the liquid hydrogen fuel flowing into them at minus-420 degrees Fahrenheit (minus-250 degrees Celsius). If not, the resulting damage could lead to an abrupt engine shutdown and aborted flight.
Mission managers accepted the additional risk posed by the engine issue as well as a separate problem: cracks in the rocket's insulating foam. But they acknowledged other problems — like fuel leaks — could prompt yet another delay.
That didn't stop thousands from jamming the coast to see the Space Launch System rocket soar. Local authorities expected massive crowds because of the long Labor Day holiday weekend.
The $4.1 billion test flight is the first step in NASA's Artemis program of renewed lunar exploration, named after the twin sister of Apollo in Greek mythology.
Twelve astronauts walked on the moon during NASA’s Apollo program, the last time in 1972.
Artemis — years behind schedule and billions over budget — aims to establish a sustained human presence on the moon, with crews eventually spending weeks at a time there. It's considered a training ground for Mars.
Twitter readies edit feature for premium users
Twitter said Thursday it will roll out an editing feature to subscribers of its premium Twitter Blue service later this month.
In an update on its plans to introduce an edit button, the social media company said it has been testing the feature internally, which it said is one of the most requested features to date.
The edit function will give users 30 minutes to make changes to their 280-character messages such as fixing typos or adding hashtags after first publishing a tweet.
To make it clear that a tweet has been modified, they'll be labeled and appear with an icon and timestamp. Users can look up past versions of the tweet by tapping the label.
Twitter said it's testing the edit feature with a small group of users so it can identify and resolve potential issues.
“This includes how people might misuse the feature,” the company said in a blog post. “You can never be too careful.”
The time limit and version history play an important role, Twitter said. “They help protect the integrity of the conversation and create a publicly accessible record of what was said.
Twitter hinted that the edit feature would eventually be rolled out to all users. Testing helps the company understand how it impacts the way people use Twitter “as well as plan for and anticipate what might happen if we bring it to everyone,” spokeswoman Stephanie Cortez said.
Many Twitter users — among them, Kim Kardashian, Ice T, Katy Perry and McDonald’s corporate account — have long pleaded for an edit button.
The company said in April that it has been working on the feature since last year, a day after Tesla CEO Elon Musk polled his followers on whether they wanted an edit button. About three-quarters of the 4.4 million respondents said yes.
Later that month, Musk offered to buy Twitter for $44 billion with the promise that his ownership would bring big changes to the service. He has since attempted to back out of the deal citing concerns about fake accounts and whistleblower allegations of poor cybersecurity, setting the stage for a bruising legal battle over whether he has to go through with the purchase.
The premium service costs $4.99 per month.

realme Pad Mini Review: Is it a worthy budget iPad mini of android?
In the recent years smartphone brand realme has got huge popularity among the youths because it didn’t limit itself to one or two features, like camera, processor, etc. Instead they carved out value-for-money devices that brought a unique blend of features, performance, and price. In this legacy, its first tablet, the realme Pad Mini was launched on 8th April 2022 in China. In this article, we take a detailed look at the tablet to see whether it can compete with the likes of other android tabs as well as iPads.
Key Features of realme Pad Mini
Design and Build Quality
The design of the realme would remind anyone of the early Note series from Xiaomi or the Tab 6 from Samsung. The device is rectangular with rounded edges to give it a more ergonomic look.
While the pad mini might look like Tab 6 from the back, it looks much like the iPad mini from the front. Thanks to the reduced bezels on all sides. It's not symmetrical like the iPad mini, but it's definitely a welcomed choice in its price bracket.
Read: Samsung Galaxy Z Fold4 Review: Multitasking King for Utilitarian Users
The build quality of the pad mini is quite decent. users will be getting a dual finish on the back where the back panel itself is glass with the top and bottom along with the frame is made from aluminum. However, there is no protection rating for the front and back glass.
Users will find all the traditional buttons and ports. One thing that stood out was the lack of a fingerprint sensor. understandably, brands cannot opt for under-display fingerprint sensors for such budget devices. But the lack of even a physical fingerprint sensor is disappointing. The only form of biometric protection here is the face unlock system.
Overall, the design and build quality of the pad mini is on par with other budget tablets at this price point. The cut corners for the budget are apparent as ever, but that’s just how things are with this device.

The Display
Even though users can hold the device in one hand, the screen real estate of the pad mini is much larger to suggest that it is by no means, a one-handed device. And that is thanks to the slim bezels across the 8.7-inch IPS LCD.
Most android tablets other than the high-end flagship ones still use LCD panels. The choice is obvious because of the cost and because individual pixel visibility isn’t a great factor for large-screen devices.
Moving on, the display boasts a 1340P resolution with 179 ppi density. On paper, this might seem like nothing. 1340P resolution also puts the display in a weird position as it's neither something that will blow away with performance nor will it let down.
Read: How to Prevent Facebook Hacking: Security measures from Mobile, Desktop
The display choice is somewhat understandable as most android tablets from budget to mid-level range come with a similar setup. We checked the outdoor visibility of the tablet and it was legible in auto brightness mode. There will be occasional color shifts here and there as it is still an LCD panel. But the overall consumer experience will be satisfactory for the price it comes at.
The Camera
Cameras are never the strong suits of any tablets. It feels like back cameras are included in a tablet for the sake of including one. The story is also similar to the front-facing one. With the Realme Pad mini, users will be getting an 8 MP shooter on the back and a 5 MP shooter on the front.
There is nothing great or mentionable about these sensors. These are just other generic lenses that are good for casual shots here and there but nothing that can be called photography standards.

Moving on to the front, the 5 MP camera will be good enough for video calls or conferences. It isn’t an ideal selfie shooter in any way. And to be honest, that has been the goal of Realme to begin with.
And as for the main sensor, it is also aimed as a document scanner rather than a photography tool. Cameras in the tab are all about work utility so there’s hardly any room for complaints.
Processor and Performance
The Realme Pad mini comes with a Unisoc Tiger T616 processor based on the 12 Nm architecture. The octa-core processor has a chip design of 2 2.0 GHz Cortex-A75 and 6 1.8 GHz Cortex-A55 chips.
Read Asus ROG Phone 6 Review: Pros, cons of the hardcore gaming beast
This is a complete entry-level processor which isn’t going to be performance-heavy. But that is hardly stopping the device from being a utilitarian device. Users will be able to blaze through everyday tasks like browsing the web, social media, or content consumption. The processor can even power graphics-intensive games at mid-range settings.
The only drawback is that the device gets heated easily with processor-intensive tasks. Other than that, the performance is right in line with any budget smartphones or tablets out there.
Battery and Charge Time
The realme Pad mini is equipped with a 6400 mAh battery to power the large display. Thankfully, users will also be getting an 18W fast charger in the box which will roughly charge up the device in about 2 hours.

Price of realme Pad Mini
Realme Pad Mini is officially available in Bangladesh. The price of the Pad mini is 21,349 BDT.
Verdict
The android tablet has always been a hit or miss for whoever tried to venture into this space. Unlike Apple, no company was able to enjoy unrivaled success as the iPads still account for the majority of tab sales across countries.
realme here didn’t try to reinvent the wheel. Rather they took the existing cues and made a device that delivers on all fronts. Other than the camera, there really isn’t much to complain about the realme Pad mini. And that really makes it a great budget option for those looking for an android tablet in the market.

Take 2: NASA aims for Saturday launch of new moon rocket
NASA will try again Saturday to launch its new moon rocket on a test flight, after engine trouble halted the first countdown this week.
Managers said Tuesday they are changing fueling procedures to deal with the issue. A bad sensor also could be to blame for Monday’s scrapped launch, they noted.
The 322-foot (98-meter) rocket — the most powerful ever built by NASA — remains on its pad at Kennedy Space Center with an empty crew capsule on top.
The Space Launch System rocket will attempt to send the capsule around the moon and back. No one will be aboard, just three test dummies. If successful, it will be the first capsule to fly to the moon since NASA’s Apollo program 50 years ago.
Read: NASA scrubs launch of new moon rocket after engine problem
Proceeding toward a Saturday launch will provide additional insight, even if the problem reappears and the countdown is halted again, said NASA’s rocket program manager, John Honeycutt. That’s better “than us sitting around scratching our heads, was it good enough or not.”
“Based on what I’ve heard from the technical team today, what we need to do is continue to pore over the data and polish up our plan on putting the flight rationale together,” he said.
During Monday’s launch attempt, readings showed that one of the four main engines in the rocket’s core stage could not be chilled sufficiently prior to the planned ignition at liftoff. It appeared to be as much as 40 degrees Fahrenheit (5 degrees Celsius) warmer than the desired minus-420 degrees Fahrenheit (minus-250 degrees Celsius), the temperature of the hydrogen fuel, according to Honeycutt. The three other engines came up just a little short.
All of the engines appear to be fine, according to Honeycutt.
The chilling operation will be conducted a half-hour earlier for Saturday afternoon’s launch attempt, once fueling begins that morning. Honeycutt said the timing of this engine chilldown was earlier during successful testing last year, and so performing it sooner may do the trick.
Read: Facebook parent settles suit in Cambridge Analytica scandal
Honeycutt also questioned the integrity of one engine sensor, saying it might have provided inaccurate data Monday. To change that sensor, he noted, would mean hauling the rocket back into the hangar, resulting in weeks of delay.
Already years behind schedule, the $4.1 billion test flight is the opening shot in NASA’s Artemis moon-exploration program, named after the twin sister of Apollo in Greek mythology. Astronauts could strap in as soon as 2024 for a lap around the moon and actually attempt a lunar landing in 2025.
Android 13: Features, Biggest New Additions
Android 13 was officially released by Google as the most recent version of the Android operating system on August 15, 2022. The introduction of the redesigned Pixel series was timed to coincide with the massive update to Material You. The Google Pixel 6, 6 Pro, Pixel 5a 5G, Pixel 4, 4a 5G, 4XL, 5, and 5XL will be among the devices that are certain to get support for Android 13. It offers a large number of new user-facing features and functionalities that you should get familiar with. This operating system update is intended to cover as many of the newly introduced features as possible. Stay with us to know more about Google's latest Android OS, Android 13.
What are the Significant Additions to Android 13
Wallet Access
Before the release of Android 13, Google Pay transformed into Google Wallet, which serves as a one-stop shop for all of your necessary items. The new version of Google Wallet will, at some point in the future, be able to enable digital forms of identification in addition to the payment cards and loyalty cards that are presently supported by Google Pay.
Google is collaborating with governments all around the globe to support driving licenses, and it seems like a few states in the United States will be the first to adopt this initiative before the end of this year.

In addition to a safe location to keep information on your vaccination history, you will get office badges, hotel room keys, and digital automobile keys. When you search for directions using Google Maps, you will be able to see how much money is left on your metro card since all of this will be connected with other Google applications as part of Android 13.
Multi-device Play
After laying the framework with Chromecast and Fast Pair, Google aims to make the transition between devices even smoother in Android 13. The casting process is being expanded to include not just televisions, computers, and mobile gadgets, but even certain automobiles. In the event that you are viewing a video on a tablet and a call comes in on your phone at the same time, your headphones will switch the audio for you automatically.
Soon, it will be possible to copy text, online URLs, and photographs on a phone, and then paste them on a tablet without first having to manually share them with the tablet. This capability will become available soon. All of this is made feasible by the upcoming smart home standard known as Matter, which will be integrated into Android 13 from the ground up.

More Security
Android 12 placed a significant emphasis on security, but there is still opportunity for further development in this area. One of the key priorities is RCS support for Google Messages, which is gaining end-to-end encryption for group conversations. At the moment, it can only be used to send messages between two people, but later on in this year, support for a larger audience is expected to become available.
Apps will now be required to ask permission for individual files or images prior to sharing, rather than gaining access to your entire photo library, and a new security screen will highlight areas that you might want to improve in order to keep your data safe from those who would do you harm. This is done in order to keep your data safe from those who would steal it.
More Stuff That Relates to You
If Android 12 was the point of departure for a whole new visual design, then Android 13 is going to simplify it even more than it already is. For more granular control over the appearance of your home screen, Google has made it possible for third-party app icons to now match the colors that you choose in addition to those that Google provides.
Read How to Use eSIM in Bangladesh?
There are now a number of free presets available for you to choose from if you do not want the colors of your theme to match the wallpaper that you have chosen. The material you skills have been added to the media control notification tray widget. It may now change color depending on the artwork of the album, and the progress bar can also move along to the rhythm of the tunes you are listening to.
Tablet-friendly
Although it was first tested as part of Android 12L, an experimental operating system specifically designed for large displays, it now seems like Android 13 will make the most of those adjustments.
The new taskbar will be located at the bottom of the screen, making it easier to access commonly used programs even while they are currently being shown on the screen. Do you want to see this in full screen? You have the option to conceal the taskbar and then swipe to reveal it again.
Read Home Audio Speaker Buying Guide, Price Ranges in Bangladesh
The notification tray has been overhauled with a new two-column structure that makes greater use of the additional space afforded by tablets. This new design can be found in the updated version of the app. Multitasking through dragging and dropping windows around is now supported, and you can also pin app pairings to the Recents pane for easy access.
More than 20 of Google's own applications, such as YouTube Music and Google Maps, are in the process of being updated to accommodate larger screens as part of an upcoming project by Google. The improvements should be available far before the official release of Android 13, and beta testers will have the opportunity to try them out before everyone else.
Opt-in Notifications
Android has traditionally been superior to iOS when it comes to the management and presentation of alerts. Nevertheless, there is one aspect of Apple's ecosystem that we like and value. Applications need to expressly seek you for permission before they're authorized to send alerts.
Read Cloud Computing Benefits: Perfect Cloud Service Provider Choosing Tips
When you install applications on Android 13, you will no longer be able to get installation alerts unless you specifically grant the permission to do so. Previously, Android allowed apps to send installation notifications. Be aware that this change will only affect applications that were installed after you upgraded to Android 12, thus it will not affect any functionality that was already in place.
Conclusion
The features of Android 13 include "user-facing" options and changes. You may expect to see or run across the new features when you update your phone. However, this most recent version of Google's operating system incorporates a variety of changes and upgrades that take place behind the scenes.
Though the options and features of Android 13 seem more sophisticated and reliable than Android 12, it does not have as many features as the ancestor version. Over the next few months, we anticipate a large number of original equipment manufacturers, or OEMs, including Samsung, Oppo, OnePlus, and many more, to give their own unique take on this construct.

Samsung Galaxy Z Fold4 Review: Multitasking King for Utilitarian Users
Expectations from Samsung have always been high. In line with their innovative approach, the company launched its first-ever foldable smartphone, the Galaxy Z Fold in 2019. While the first had a few critical drawbacks, the company has since fixed and upgraded its offerings. Samsung launched the Galaxy Z Fold 4, the latest and greatest in their foldable lineup on august 25th 2022. In this article, we take a look at the specs and ergonomics of the device to see whether it can replace conventional smartphones.
Key Specifications of Samsung Galaxy Z Fold4
Design and Build Quality
The design elements of the Samsung Galaxy Z4 Fold are similar to the previous iterations. The display, both the inside and cover are exactly the same size as last year. But Samsung has made some cool changes in the overall dimensions. The device is now slightly thinner and shorter all the while maintaining the same screen real estate. It just makes the device more manageable.
Everything else is positioned right where they were last year. On the side, there is the power and volume rocker. The power button acts as the side-mounted fingerprint scanner. As expected, there is no headphone jack on the device.

Samsung has stacked the Z Fold4 with cameras just like last year. The inner and the cover display each has a selfie shooter along with triple primary lenses.
The hinge mechanism has been updated to make way for a smoother opening and closing. But you still hear that bone squeaking noise albeit at a lower pitch.
Overall, the design and the build quality remain the same. We get Samsung’s idea of refined iterations and the company clearly went in that direction.

The Display
There are two displays on the Samsung Galaxy Z Fold4. The main inner display is a Dynamic AMOLED 2X panel with a 120 Hz refresh rate and HDR10+ support. The 2X is just a fancy adage to surmount the foldability of the device.
The 7.6-inch display also boasts a 1200 nits peak brightness for perfect outdoor visibility. Coming to quality, this display is everything you’d expect from Samsung. It's bright, color-accurate, and pixel-dense. The viewing angles are perfect with zero color distortion.
The only noticeable gripe with the inner display is the crease. It's still present in the Z Fold4 and might be an eyesore for some.

While it is much more toned down than previous generations and most users say they get used to it after a while, it is still there and becomes increasingly apparent when using dark mode.
There is also a protective layer over the display which is an absolute dust and fingerprint magnet.
Other than these minor drawbacks, the Z Fold 4 features a perfect set of displays that is both functional and utilitarian all the while being at the top of its range.

The Camera
Users will be getting a total of five cameras with the Z Fold4. The triple camera sensors on the back are a 50 MP dual pixel PDAF sensor with a 10 MP telephoto and a 12 MP ultrawide complementing the main one.
This time, Samsung means business as they upgraded the sensor to be better in line with their traditional flagship devices. Each of the sensors delivers its capabilities.
The main sensor takes far better pictures compared to the Z Fold3. There is great preservation of the dynamic range and details. The exposure was also perfect in every shot during outdoor shots.

The cameras also performed well in artificial lights. Samsung automatically varies the shutter speed to capture more light which results in a near grain-less image even in minimal lighting conditions.
There are two selfie cameras on the Z Fold4. One is a 4 MP under-display one on the inner screen and the other is a 10 MP one on the cover display. The under-display camera is a disappointment just as last year. It’s probably only good for video calls or conferences, nothing more. On the other hand, the cover display camera does a better job and produces usable quality pictures.
The videography of the Z Fold4 is rated at 4K at 60 fps. With the specs and capabilities, one would expect up to 8K support like the standard models. But unfortunately, users won’t be getting that with the Fold4.

Processor and Performance
The Samsung Galaxy Z Fold4 is powered by the Snapdragon 8+ Gen 1 chipset built on the 4 Nm architecture. This is the latest and greatest processor from Qualcomm for mobile use. The processor has 1 3.19 GHz Cortex-X2 and 3 2.75 GHz Cortex-A710 and 4 1.80 GHz Cortex-A510 chip designs for efficient yet powerful output.
And the results are clearly visible. The Z Fold4 blazes through whatever that’s thrown at it. Samsung has developed a unique split screen feature where it splits at the joint. This allows for a perfect multitasking operation. Many users are calling it the best multitasking device out there because of its sheer processing capability and ease of use.
In addition to multitasking, users will also enjoy superior performance in gaming. The device can play the leading 3D graphics-intensive titles with ease and on max settings.

To sum it up, the processor and performance of the Z Fold4 are on par with the best flagships out there. In fact, it even outshines many because of the multitasking usability.
Battery and Charge Time
The Samsung Galaxy Z Fold4 comes equipped with a 4400 mAh battery. Now the 4400 mAh battery might seem very small for a 7.6-inch device. But the efficiency of the 8+ Gen 1 chip and the cover display means that the device will be able to comfortably last a day’s use on a single charge.
There is also 25W fast charging included in the device which can charge it up to 50% in 30 minutes.

Price of Samsung Galaxy Z Fold4 in Bangladesh
The Samsung Galaxy Z Fold4 is currently available for pre-order in Bangladesh. Users can pre-order the device from the Samsung website for around 240,000 BDT for the 12/256 Gb variant. The price is subject to change depending upon company policy and other issues.
Final Words
The Samsung Galaxy Z Fold4 is an incremental upgrade to the Z Fold3. The company addressed the issue regarding ergonomics and cameras. These are welcomed changes that made the Z Fold4 even more streamlined as a daily driver.
However, the creaking hinge noise and the crease on the display are still something that might be a deal breaker for some. But as things stand now, the Z Fold4 is slowly becoming a mainstream daily driver, albeit at a very high price point and out of budget for many.
