Technology News ,India :-The Indian government is dedicated to ensuring that clean and safe tap water is available to all rural households in the country. This commitment led to the launch of the Jal Jeevan Mission (JJM) in August 2019. The mission aims to provide a regular and long-term supply of high-quality tap water to rural households, with the government working in partnership with states for its implementation.Responsibility for planning, approval, implementation, operation, and maintenance of drinking water supply schemes, including those under the Jal Jeevan Mission, rests with State/UT Governments, as drinking water is a state subject. The central government supports states by offering both technical expertise and financial assistance.Since the initiation of the Jal Jeevan Mission in August 2019, substantial progress has been achieved in improving access to tap water in rural households. Initially, only 16.8% of rural households (3.23 Crore) had tap water connections. According to the latest reports from States/UTs as of December 7, 2023, an additional 10.53 Crore rural households have been provided with tap water connections under JJM. As of this date, approximately 71.51% (13.76 Crore) of the country's 19.24 Crore rural households have tap water supply in their homes.Given that drinking water is a state subject, the choice of technology to address water quality issues lies with the respective State/UT Governments. The Indian government collaborates with academic institutions like IITs to provide advice on various technologies available to tackle water quality challenges.The Indian Institute of Technology (IIT) - Madras, for instance, has developed the 'AMRIT' (Arsenic and Metal Removal by Indian Technology) technology. This innovative solution employs nano-scale iron oxy-hydroxide to selectively remove arsenic from water when passed through it. 'AMRIT' serves both domestic and community levels. This technology, recommended by the Department of Drinking Water and Sanitation's 'Standing Committee,' addresses concerns related to water and sanitation.In areas affected by water quality issues, including arsenic, short-term measures are taken until long-term piped water supply schemes from safe water sources are implemented. According to reports from States/UTs in the Integrated Management Information System (IMIS) as of December 6, 2023, all 378 arsenic-affected habitations without tap water supply have been provided with safe drinking water through Community Water Purification Plants (CWPPs) for drinking and cooking purposes.

Space News ,japan :- Japan's Smart Lander for Investigating Moon (SLIM) achieved a successful landing on the Moon, marking Japan as the fifth country to accomplish a gentle touchdown on the lunar surface.Equipped with instruments like a camera, laser altimeter, and magnetometer, the Japan Aerospace Exploration Agency (JAXA) confirmed the spacecraft's landing. These tools are intended for studying the Moon's geology, environment, and resources.However, a setback occurred as SLIM's solar panel malfunctioned, leading to a power generation failure. This complication may curtail the spacecraft's operational time on the moon, according to the Japanese space agency.Observations from space enthusiasts, based on limited spacecraft data, indicate that SLIM's landing wasn't entirely smooth. The orientation of the spacecraft suggests the possibility of rolling during the landing. Currently relying on battery power, SLIM faced uncertainty immediately after landing, with the live stream ending inconclusively. JAXA scientists have been working to address the issue, but progress has been limited.The batteries are projected to last only a few hours, adding to the challenges faced by Japan's SLIM mission on the lunar surface.

Space News ,Japan :- Japan's "Moon Sniper" robot explorer has made it to the moon's surface, but we're not sure how well it's doing, says the Japan Aerospace Exploration Agency (JAXA).The Smart Lander for Investigating Moon, or SLIM, mission landed around 10:20 a.m. ET on Friday (12:20 a.m. Saturday Japan Standard Time). JAXA is currently checking on the lander's condition and will share updates during a press conference.If the landing went well, Japan would become the third country in this century, and the fifth ever, to successfully land a spacecraft on the moon.SLIM, also known as "Moon Sniper," is a small robot explorer launched in September. It's nicknamed "Moon Sniper" because it uses new precision technology for a super precise landing. Unlike previous missions that covered large areas, SLIM targets a landing site just 100 meters (328 feet) across. Its "smart eyes," an image-matching-based navigation technology, takes rapid photos of the lunar surface and adjusts the spacecraft's descent for a precise touchdown on a sloped surface.The Moon Sniper is aiming for a landing site near the Shioli crater in the Sea of Nectar, south of the Sea of Tranquility where Apollo 11 landed in 1969. If the landing is successful, it will briefly study rocks at the site, providing insights into the moon's origin.Scientists are particularly interested in rocks created by impacts on the moon, as they can offer information about the moon's formation. These rocks, resulting from meteorite strikes, provide a peek into the moon's interior and reveal details about its minerals and composition.Landing near sloped, rocky areas around craters is usually risky, but JAXA believes its lander has the technology to safely touch down on such terrain.This moon landing is part of a global space race, with various countries attempting missions in the past year. India, for instance, landed on the moon's south pole in August. However, there have been failures too, like Japan's Hakuto-R lunar lander and Russia's Luna-25.The competition arises from a desire to access water trapped as ice in permanently shadowed regions at the lunar south pole. This water could be crucial for future space exploration, serving as drinking water or fuel. The SLIM lander, if successful, might offer a design that could be used not only on the moon but also on planets like Mars, according to JAXA.

Space News ,China :- A Chinese space startup called Landspace achieved an important milestone by successfully testing a reusable rocket. The test involved a rocket called Zhuque-3 VTVL-1, which took off vertically and landed vertically at the Jiuquan spaceport. This event marked a significant step in the development of their stainless steel Zhuque-3 rocket, initially announced in November 2023. Landspace is targeting the first flight of Zhuque-3 in 2025, with the initial vertical takeoff and landing (VTVL) test originally planned for the previous month.The test rocket, fueled by methane and liquid oxygen, reached an altitude of approximately 350 meters during its brief 60-second flight before safely landing in a predefined area. Landspace reported that the landing was precise, with an accuracy of about 2.4 meters and a landing speed of around 0.75 meters per second.The Zhuque-3 rocket is a two-stage vehicle, measuring 4.5 meters in diameter and having a total length of 76.6 meters. It will weigh about 660 tons at liftoff and will be powered by nine Tianque-12B engines. The rocket's payload capacity to low Earth orbit (LEO) is expected to be 21,000 kilograms when used in an expendable mode. Depending on recovery scenarios, it can carry up to 18,300 kg or 12,500 kg when the first stage is recovered downrange or returns to the launch site.This achievement reflects the growing competition in China's commercial launch sector to develop reusable launch vehicles. Landspace's test follows similar "hop" tests conducted by another Beijing-based startup, iSpace, emphasizing the race to create reusable rockets in the country.The development of reusable rockets in China gained momentum after the government allowed private capital to invest in the space sector in 2014. Several other Chinese companies, such as Deep Blue Aerospace, Linkspace, Galactic Energy, and CAS Space, have also conducted various tests and are planning their own launches with reusable technologies.Landspace has ambitious plans for the future, aiming to launch three Zhuque-2 rockets in 2024, with a goal to increase launch frequency to six times in 2025 and twelve times in 2026. Additionally, the company is working on a powerful engine, expected to be ready in 2028, which will drive a larger reusable launch vehicle challenging a planned reusable rocket by China Aerospace Science and Technology Corp. (CASC), the country’s state-owned main space contractor. The overall trend suggests a significant push towards reusable rocket technology within various Chinese space entities, both state-owned and commercial.Landspace at 0800 UTC today conducted a successful 60-second, 350m hop at Jiuquan.

Space News , Japan :- Japan is gearing up for a historic lunar mission as its robotic SLIM spacecraft aims for the country's maiden successful moon landing on January 19. The mission, formally named "Smart Lander for Investigating Moon" (SLIM), is set to commence its touchdown operations at 10 a.m. EST on Friday, with a gentle landing anticipated 20 minutes later, provided all goes as planned.The live coverage of this landmark event will be available on Space.com, courtesy of the Japan Aerospace Exploration Agency (JAXA), or directly through JAXA's channels. The coverage is scheduled to begin at 9 a.m. EST.SLIM embarked on its journey atop a Japanese H-2A rocket on September 6 of the previous year. Sharing its launch with an X-ray space telescope named XRISM, SLIM navigated a lengthy and energy-efficient route to reach the moon. XRISM was successfully deployed into low Earth orbit after launch, delivering its initial test images post a triumphant checkout period.Following its arrival in orbit around the moon on Christmas Day, SLIM spent three weeks preparing for its impending landing. The ambitious objective is for SLIM to touch down within 330 feet (100 meters) of a predetermined spot on the rim of the moon's Shioli Crater. This mission aims to showcase the technological prowess required for precise lunar touchdowns.The nonprofit Planetary Society emphasized SLIM's mission architecture, expressing the aspiration to redefine the standards of lunar landing missions, moving from convenient landing sites to precise, targeted touchdowns.Achieving success in this endeavor would propel Japan into an exclusive group of nations that have accomplished soft landings on the moon. To date, only four countries—the Soviet Union, the United States, China, and India—have achieved this remarkable feat.Notably, SLIM is not Japan's inaugural attempt at a lunar landing. The OMOTENASHI lander, part of NASA's unmanned Artemis 1 mission in November 2022, aimed for the moon but did not reach its destination. In April of the same year, the Hakuto-R spacecraft, developed by Tokyo-based company ispace, encountered a crash during its landing attempt due to complications arising from the moon's rugged topography.This lunar mission is unfolding against the backdrop of recent setbacks in lunar exploration, including a failed attempt by Astrobotic's Peregrine lander. The American lander experienced a fuel leak shortly after its January 8 launch, leading to the cancellation of a planned mid-February landing. Despite the fuel leak, Peregrine managed to reach lunar distance before redirecting back toward Earth, with an anticipated collision over the South Pacific on January 18.

Space News ,U.S :- Axiom Space is all set to launch its third private astronaut mission to the International Space Station (ISS). However, there are some technical issues that have made the launch preparations a bit tight on schedule.On January 16, Axiom, NASA, and SpaceX officials shared in a media teleconference that they are moving forward with the planned Ax-3 mission launch to the ISS on January 17. The Falcon 9 is scheduled to take off at 5:11 p.m. Eastern, carrying a Crew Dragon spacecraft that will dock with the station about 36 hours later.Originally, the launch readiness review, the final major check before launch, was supposed to happen before the media briefing. However, it got postponed to early January 17 to allow more time for the teams to get everything ready.Over the weekend, inspections revealed issues with joints connecting the Dragon spacecraft to the Falcon 9 upper stage. Two of the four joints were adjusted a bit differently than usual, according to Benji Reed, senior director of human spaceflight programs at SpaceX. As a precaution, SpaceX decided to replace the connections, causing a delay in launch preparations.Another challenge found during preparations involved the parachute system. Inspections from a previous cargo Dragon spacecraft splashdown in December showed that certain straps, known as "energy modulators," didn't function as intended. SpaceX took precautions by untwisting these straps in the Ax-3 Crew Dragon spacecraft's parachute system. They are collaborating with NASA to make sure this won't be an issue during the mission.Despite these challenges, the launch teams worked hard to keep the launch on schedule. The Ax-3 mission is part of Axiom Space's series of private astronaut missions, paving the way for commercial modules on the ISS. These modules will eventually become the core of a new commercial space station after the ISS retires.Axiom aims to continue these missions twice a year until their first module is installed in late 2026. The next mission, Ax-4, is tentatively set for the fall of 2024.The Ax-3 mission is led by Michael López-Alegría, Axiom's chief astronaut, and includes pilot Walter Villadei from the Italian Air Force. The mission specialists are Alper Gezeravcı from Turkey and Marcus Wandt from Sweden. Gezeravcı will be Turkey's first person in space, and Wandt will be the second from Sweden, thanks to collaboration with the European Space Agency.While the Ax-3 team faces challenges, they are excited about the mission, especially López-Alegría, for whom this will be his sixth trip to space. He expressed his enthusiasm, saying, "As long as they ask me to fly, my hand will be raised."

Space News ,World :- Astrobotic recently shared an important update about its Peregrine spacecraft. Originally planned to land on the moon, the spacecraft faced a challenge due to a propellant leak. Instead, it is now set to reenter Earth's atmosphere soon.In their social media post on January 13, Astrobotic explained that Peregrine, launched with the help of Vulcan Centaur, ended up in an unusual orbit, going beyond the moon's orbit. The plan was for it to swing back around the Earth and enter the moon's orbit. However, the propellant leak created uncertainty about the spacecraft's path.The company now predicts that Peregrine is heading towards Earth and will likely burn up in the atmosphere. The exact time and location of reentry were not disclosed, but estimates point to late January 18 near Australia.On January 14, Astrobotic confirmed their decision not to attempt any maneuvers with the remaining fuel. They consulted with NASA and received recommendations from the space community and the U.S. Government on the safest course of action. The decision was made to let the spacecraft burn up during reentry, ensuring the responsible conclusion of Peregrine's mission and preserving the future of cislunar space.Peregrine faced a propellant leak shortly after its January 8 launch. Astrobotic traced the issue to a valve failure in the helium pressurization system, causing an oxidizer tank to rupture. Despite initial concerns about running out of propellant, the spacecraft continues to operate. Astrobotic has even powered on several payloads, including those from NASA's Commercial Lunar Payload Services (CLPS) program.In the latest updates, the propellant leak has slowed considerably, and the spacecraft has enough fuel to maintain its attitude and perform small maneuvers until the end of the mission. A media briefing about the mission is scheduled for January 18, where NASA and Astrobotic will provide more details.

Technology News , World :- In the year 3023, people might have an incredible way to see how the Arizona desert looked a thousand years ago. It's all thanks to a unique project known as the Millennium Camera, an art and science initiative by Jonathon Keats, an experimental philosopher from the University of Arizona College of Fine Arts. This camera aims to capture an extraordinarily long-exposure photo, spanning a thousand years, offering future Tucson inhabitants a glimpse of what has changed and what has remained the same.To achieve this, Keats drew inspiration from the past, designing the Millennium Camera based on the ancient pinhole camera, invented around 1,000 years ago. The camera is a copper cylinder with a thin sheet of 24-karat gold on one end, featuring a tiny hole punched into it. Sunlight passes through this hole, reaching a light-sensitive surface coated with layers of rose madder, an oil paint pigment.Mounted on a steel pole and pointed toward a Tucson neighborhood, the controlled light exposure will gradually fade the pigment, creating a millennium-long exposure photo. Over the centuries, there will be noticeable movement in the frame, making future observers squint to decipher the changes. However, Keats finds charm in this, as stable elements like mountains will appear bold, while changing objects like buildings will be semi-transparent, emphasizing the impermanence of humanity.Despite the ambitious plan, uncertainties loom over the camera's fate, considering natural disasters, theft, or changes to the landscape over the next millennium. However, the Millennium Camera serves a dual purpose – not only as a time capsule for future generations but also as a present-day inspiration. Located near a hiking trail on Tumamoc Hill, the camera invites hikers to ponder the future while appreciating the present view. Keats envisions installing similar cameras in different directions in Arizona and in locations like Griffith Park in Los Angeles, China, and the Austrian Alps.Keats believes that contemplating potential future scenarios, even bleak ones, can motivate people to take action to shape a better future. So, whether or not the Millennium Camera survives its intended timeframe, it stands as a symbol encouraging us to think about the past, present, and future.

Technology News ,World :- Guess what? Wi-Fi is about to get a major upgrade, and it's called Wi-Fi 7, officially known as 802.11be. Brace yourself because our homes and offices are on the verge of experiencing incredible speeds—almost 5.8 Gigabits per second (Gbps). Yes, you read that right!I have a little secret to share. I find it hard to believe when Intel claims that a typical Wi-Fi 7 laptop can reach a maximum speed of 5.8 Gbps. But, let's not get caught up in the top-end numbers. What I can believe is that Wi-Fi 7 can deliver real-world speeds of around 4 Gbps, which is more than fast enough for most people, unless you're running a high-performance supercomputer cluster at home.So, what makes Wi-Fi 7 stand out from its predecessor, Wi-Fi 6E, which can reach speeds of up to 1.5 Gbps? Well, Wi-Fi 7 achieves these blazing speeds thanks to some cool new features:Increased Channel Bandwidth:- Wi-Fi 7 doubles the maximum channel bandwidth from 160MHz to 320MHz, allowing for faster data transmission. Bigger bandwidth means higher wireless download speeds.4K Quadrature Amplitude Modulation (QAM):- This feature lets each signal pack up to 120% more data into a channel compared to Wi-Fi 6E. Multi-Link Operation (MLO):- This feature allows devices to connect across two or three bands (2.4 GHz, 5GHz, and 6GHz), boosting speed and stability. It seamlessly switches to another band if one is out of range. Improved Latency:- Integrating all three bands reduces airtime restrictions, making immediate data packet transmission more likely. This is great for applications requiring low latency, like online gaming and video conferencing. MU-MIMO Enhancement:- Wi-Fi 7 supports more multi-user, multiple-input, multiple-output (MU-MIMO) spatial streams, enabling routers to communicate with more devices simultaneously, especially in crowded environments. Multi Resource Units (RU):- Unlike older Wi-Fi standards, Wi-Fi 7 allows the channel to be shared if there's available room in itWi-Fi 7 operates on the familiar 2.4GHz, 5GHz, and 6GHz bands, making it backward compatible with previous Wi-Fi standards. However, older devices won't fully benefit from its higher performance and new features.To make the most of Wi-Fi 7, all your gear needs to support the new standard. With the right equipment, you can enjoy 8K movies, augmented reality/virtual reality gaming, and lightning-fast large file downloads.For home networks, Wi-Fi 7 enhances the performance of smart home devices, providing a more reliable connection for Internet of Things technologies. The improved bandwidth and speed are perfect for families with multiple devices streaming high-definition content simultaneously.In businesses, Wi-Fi 7 supports more devices with minimal interference, making it ideal for large offices and coworking spaces. The improved speed and stability facilitate seamless video conferencing and efficient cloud-based applications.Now, here's a bit of a downside. The 6 GHz wireless spectrum, while great for fast data transfers at close range, struggles with long distances and interference from physical obstructions. However, the Federal Communications Commission (FCC) is working on a solution that will increase Wi-Fi 7's range and overall performance.Wi-Fi 7 routers are already available, but they come with a hefty price tag. If you're eager to experience the cutting edge, go ahead and invest. But for most people, it might be wise to wait until more devices support Wi-Fi 7, and prices come down. After all, this new standard is a significant leap forward in wireless technology, and it's only going to get better!

Technology News ,World :- Researchers at Harvard's School of Engineering have created an innovative lithium metal battery that can be charged and discharged over 6,000 times, surpassing other batteries in durability. The breakthrough not only introduces a novel method for making solid-state batteries but also enhances our understanding of the materials crucial for these potentially game-changing batteries.Traditional lithium metal anode batteries are considered highly desirable due to their capacity, which is ten times greater than commercial graphite anodes. This could significantly extend the driving range of electric vehicles. Xin Li, Associate Professor of Materials Science at SEAS and senior author of the paper, emphasized the importance of this research in moving towards practical solid-state batteries for industrial and commercial use.A major challenge in designing these batteries is the formation of dendrites on the anode's surface. These dendrites, similar to roots, grow into the electrolyte, causing short circuits or even fires. The researchers addressed this issue by using micron-sized silicon particles in the anode to control the lithiation reaction, preventing dendrite formation and facilitating even plating of a thick layer of lithium metal.Unlike traditional lithium-ion batteries, where lithium ions penetrate deep into the anode, the solid-state battery design constrains the lithiation reaction to the surface of silicon particles. This results in lithium metal plating around the silicon core, creating a uniform surface that prevents dendrite growth. The even surface also allows for quick plating and stripping, enabling the battery to recharge in just about 10 minutes.The researchers successfully tested a postage stamp-sized pouch cell version of the battery, which outperformed other pouch cell batteries on the market by retaining 80% of its capacity after 6,000 cycles. The technology has been licensed to Adden Energy, a Harvard spinoff company, for further development into a smartphone-sized pouch cell battery.Li and his team also identified the unique properties of silicon that facilitate the lithium diffusion process, providing a pathway to discover new materials for battery design. This research opens up possibilities for developing batteries with enhanced performance and durability, bringing us closer to a future of more efficient and long-lasting energy storage solutions.
